Transcripts
hello everyone
thank you for joining us today during
this webinar we will cover etap etrax
the latest integrated solution for
designing planning
and operating rail traction power
systems
etrax is utilized by railway operators
owners and engineering consultants as an
integrated traction power design and
management system
there are many project goals and
objectives that may be required during
the traction power project
and too many challenges are still
present due to out-of-date technology
still utilized for these projects we
will be discussing these challenges
as well as existing solutions provided
by e-trax
the solutions include an integrated ac
and dc
system that uses a digital twin
which allows traction power groups to
use the same model created in the design
and planning phase
within the operation stations for
traction scada and power management
when we do traction power analysis we
need to understand
the existing and planned substation
capacity
from there we can look to implement
energy efficiency initiatives
and enhanced trained timetables this
will allow us to reduce
energy consumption and power losses
which is a constant priority for
traction power
operators and engineers also as demand
increases
we look to analyze the existing
infrastructure to handle additional
trains
or we evaluate and optimize the system
and improve the overall design when
these changes are proposed
safety and protection is also evaluated
so there is a requirement to integrate
traction power analysis
with the ability to analyze potential
faults
perform protection and coordination
studies and optimize arc flash results
as we've discussed these project goals
and objectives with many of our users
here are some of the challenges that are
extending the timeline of these projects
we've heard things from an archaic
graphical user interface
so using old technology that hasn't been
up to date
and it's cumbersome to find the
locations of characteristics or how it's
consolidated
another one is multiple products for
multiple objectives
so we previously talked about the goal
of doing traction power studies
but then moving into short circuit
protection phases
and with that you have to have a
completely separate software
to either integrate or to
to use altogether because one product
doesn't have
everything so it's different products
for multiple objectives
we made our own but it's not up to date
many of our etab users have previously
created their own traction power
software
but have switched to etap because that
company's focus is not
on the software side they're trying to
do services not not develop and design a
software
and of course interfacing with
third-party applications many of the
data we collect or handed to us
on the front end is from different
interfaces like cad drawings or excel
data
or having the inability to bring in that
data to save time has been a problem for
many of our users
until switching to e-tracks
engineering information is manually
shared with the operations team
the engineering team does all this work
to build the digital twin to build the
model and do that analysis
and then the operation team has to
recreate that scada from scratch
without being able to take advantage of
all the information that was
input into the engineering design and
planning model
some of them are are technical issues
running ac and dc analysis in two
different databases
so in many projects you have an ac
transmission transmission system
integrated with dc traction power and ac
signaling and the softwares or the
technology they use
requires two different databases to run
each
each system the ac system and the dc
system completely separately
and then of course you have different
conditions and scenarios
and managing it is extremely time
consuming
and with these models you have
integrated rolling stock
and it's it's difficult to add the
rolling stock information and analyze
performance they don't have a library of
rolling stock information and if they do
it's very difficult to add it
themselves and then one of the ones that
are very popular right now is energy
storage having
technology having a project that can't
assess energy storage systems is a
problem today
so this is the conversations we've had
with many of the traction power
engineers and operators and and this is
why we developed etrax
etap etrax is a software for design
planning optimization and operation of
integrated ac and dc railway traction
systems
and this is done on a gis application or
a one-line diagram
and this will we will go through and
cover a lot of the quotes we previously
heard
from from existing users of this type of
technology
we will cover how etrax overcomes these
challenges
to overcome the challenges that are
prevalent within the industry
you need a traction power solution which
is your single source of truth
containing information regarding the
geographical landscape
rolling stock routes
train timetables and other information
that we will be going through
we will use this to analyze and improve
train performance
and manage the system and with etrax
this is all done with an easy to use
graphical user interface which we will
soon demonstrate
here are some of the capabilities we
will be going through specifically
etrax contains a unified time series ac
and dc
traction power simulation on one
synchronized geospatial view
and one line diagram the model includes
equipment for traction systems like auto
transformers and rectifiers
substation assets are also included and
can be pulled at any time from the
templates provided by e-trax
this is considered for trained
performance calculations which converts
mechanical characteristics of the
traction system
such as elevation track bend radius
into low demands and electrical care
calculations
and this can be expanded to attraction
e-scada
energy management system and incorporate
the real-time data
to perform predictive simulations so you
can go from design
to operation before we go into the
software
i want to summarize some points on the
foundation of the traction system
the model would be geospatial and
logical logical
being the one line diagram the
geospatial view
provides functionality to automatically
create spacing between stations
which we will soon see and the results
generated
as well as the train animation can be
seen on the geospatial view
or the one line diagram now let's take a
look at creating a model
etap allows you to import from different
file formats
including openstreetmap and excel and
others
so in this project i'm going to import
an excel file the excel file containing
information about the track segment
track nodes train stations and markers
we can provide the excel sheet to you
and you can update it with your project
information and once you import it
the gis will automatically create the
traction power system
based on that excel or the the
application that you use to import it
all the data will come in and the
modeling and the connectivity
and from there we can automatically
generate a one line diagram
so then you'll have a synchronized gis
with the one line
so we see the station and the track
information now
if you need to align equipment
we have alignment tools that allows you
to select how you want to align it and
it automatically align the station with
the routes
so now we can see the traction power
network
on the one line or the gis system
and once it's in etap you have the
ability
to add equipment with the using the
toolbar as well
so on this train station we can add
additional tracks and this is done very
similarly to
if if you're familiar with etap in
general this is done just the same as
any etap
project file with with equipment so we
can add the tracks and you'll see the
the shape total the length is
automatically generated from gis
we can add another station
and we can apply we can apply
bend radiuses so right now we can apply
the bend radiuses on different points of
the track
and update the information
and then you can reshape edge based on
that bend radius and the software will
automatically smooth out the curve
and we can add speed limit markers and
all of this will
also update the one line diagram so
they're completely in sync
so now let's look at a project we've pre
previously configured
i have a full gis view here that you can
see and you see the traction powered
network overlaid on top
and a corresponding one line diagram
and we can zoom in to see where the
train stations are we can get a closer
look
and you see here these boxes represent
the train stations
and within the corresponding one line if
i wanted to see where this train station
was i can just show
on one line view and you'll see this
automatically
changes and highlights the location of
that corresponding
station and of course i can go back the
other way
and find in my distribution view and
highlight that that station
and in the one line diagram if we zoom
out here
i can see that i have my medium voltage
traction power network
modeled so we want to take a full look
at the one line
i see my medium voltage traction power
network and the connected transmission
system
so we have our transmission equipment
connected as well
the system and that's also integrated
with
our low voltage signaling power so
in this model we have three phase single
phase
ac and dc and etrax will run
all of this in a unified engine so so
again the ability to run an
ac dc unified engine three phase or
single phase in this project
and for those who are familiar with etap
once you have the one line created
we can use the standard toolbar to add
any equipment we want
to the one line diagram from the
transmission system or the signaling
you can either use the toolbar and build
it or you can take advantage of our
templates
that we've provided within etap so if i
go to the substation folder you'll see a
number of
of templates that have been provided
that you can take advantage of in your
project
as well as create your own and save them
so if you have
if you have models that are very similar
in nature you can save them to a
template folder anywhere in your
directory pass them to any individuals
from your team
to access and take advantage of from
project to project
next we can configure and assign our
train information
so i can pull up the track groups
directly from gis
and that one opens up the specific one
that i selected
but within here i can see all the track
groups that my
that is composed of my project and this
goes from station to station and as i
select it
it the gis is updated based on my
selection and all the components
incorporated in that track group are
shown
with the details now if i change
anything in gis
this tabular view is automatically
updated so this is in sync
and this contains our all the the
information within the track group
gis components lengths bend radiuses
anything that we need to consider is
incorporated here
after the track groups we can look at
the route so each route again is
highlighted
and as i select the route the gis is
updated to show the one i'm selecting
and it's color coded so we can we can
assign a color
track route and that's done in the theme
manager
so if i go to route i can assign a color
the distance is automatically calculated
and the stations
are identified for each route and per
group
so we know track one contains these four
track groups
from from one station to another and the
distance
after that we have our routes and we go
to to
input or import the train schedule
so you can import from an excel sheet or
you can manually
add one so you can add the number of
trains train name start time headway
time dwell time
or we can import this data or you can
have the if it's an existing project and
you don't have this information you can
have etrax
automatically populate a train schedule
to get started
and this this does you can assign the
trained schedules per day
so i can assign specific days for these
schedules and you can do it per
route and of course all of this is
unlimited there's no limit to what you
can do
and this will contain the arrival time
the dwell time departure and trip time
per station and you have it for each
train
so each train is shown
now what are these trains composed of
that's in the train config
so i can assign a train from the etap
library we can assign passenger or
freight train
and we can put the acceleration limit
and deceleration limit
and you select it from the library which
many people who are familiar with etap
are familiar with the etap library
so there's different manufacturers and
models within the library
and you and you can add them here or you
can have us add them so you can call in
and have
us add them and these libraries can be
project specific so this one's a
minimized to this project
however if you have you can use the main
etab library that contains
all of the locomotives that we have or
create a project specific one
and this is unlimited so you can assign
as many train configuration
configurations as you like and then
assign those configurations to the train
ids
so we have the train ids that we saw on
the track and here i can select which
configuration i want the number of
consists it contains
and you can mix and match so if if you
want you can have
it's very flexible in the sense that you
can have train 9517
contain a combination of different
configurations
there are different results we we can
analyze to improve trained performance
we can determine the tractive effort
which considers the performance curves
for tractive or breaking versus speed
incorporated in the locomotive library
we can analyze trip times
calculate power consumption and demand
and since we do have the integrated
rolling stock library we can
easily simulate the effect of upgrades
and retrofits
and all this analysis can be done while
incorporating planned
or unplanned events in different
scenarios
to get a complete picture of train
performance in many different conditions
or configurations
and not only is it analyzing the train
itself but it's taking a look at the
overall infrastructure
there's different methods and analysis
and studies
we can do to optimize the substation
location and capacity
with an existing system it's very easy
to identify
power supply inadequacies and pinch
points
an etap wall will automatically generate
a train schedule an optimized train
schedule for an existing system
but if you have a new system you need to
consider multiple multiple scenarios
an e-trax allows for an unlimited amount
you can have different revisions and
configurations
make many different changes to the
system incorporating them into scenarios
and pull out the scenario
at any time to rerun the study and when
you're sizing equipment
many industry standards are incorporated
and it automatically sizes that
equipment against industry standards
or alert you if you've exceeded any of
the guidelines
as we all know there's a large demand
with renewable energy
and traction power systems are not any
different
different technology is used to maximize
energy efficiency such as battery energy
storage
flywheel storage and regenerative
braking
this project that we were previously
working on does have a battery energy
storage system and regenerative braking
so i can look at the battery energy
storage
through the editor and this is selected
from the etap libraries i have a lithium
ion battery
and the bms is set that if dc bus
4 is greater than 101 percent
then dc bus 4 will charge the battery
but if dc bus
4 which is here becomes less than 100
percent
then this battery will discharge
improving the voltage at this location
before we run this case let's take a
look at the whole the solution
parameters
so we know we're running an unbalanced
ac dc unified engine
and here i can assign what i'm going to
run
what i'm going to include in my
simulation so i'm going to run a
simulation for monday
and i'm going to select the tracks i'm
going to run
i'm going to run track 1 2 3 4 and you
can also select the stations that you
want to run
i'm going to run them all for monday and
you can do it for a user-defined
specified amount of time
or i can do it for the complete train
schedule
you also can assign particular events so
in the study case
in the study case i have these events
set for 9 00 am
i have specific amount of switches that
are being open
and others that will close at the same
time so you can configure different
events
and isolate different equipment and that
will
be incorporated into the simulation at
the specified time
we have certain alarming you can set so
you can do loading alarming you can look
at voltages at the bus or track nodes
you have alarming specific to the
pentagraph so you have the critical
alarm set you can apply marginal if you
like
set the duration that that it needs to
exceed to alert you
and then transfer and then alerts for
the transformer and rectifier
specifically
so we have average load rolling demand
and peak demand
the duration and of course the interval
so this will
alert you based on the options you've
selected here
and finally determining which devices
you want to plot
so any of the devices you select here
will create an output plot
that will show after the simulation is
run we have certain amount of buses
selected
we have the battery selected dc track
nodes are included
and we'll show some of the plot
characteristics after the simulation
we run the simulation from the toolbar
this toolbar allows you to access
specific items for e-tracks one of them
being the train schedule that we
uh accessed earlier from the gis
you can actually access it from the
toolbar directly as well
display options which will help
determine which results you're going to
show
on the screen once the train is running
so we'll add a couple more options to
the train results
and from here i can run the calculation
now this system will show you how much
time is the last and how much time you
have remaining so you'll always know
what you have remaining for the
simulation to take for the simulation to
complete
so initially i see my initial conditions
of the system
where the trains are starting you can
see the starting location of each train
you see the bus voltages and you can see
this across the entire transmission
system
so again the results are running across
the transmission system
and we'll continue to do so as we move
the trains across their
their routes and also to get a visual
effect on the results
we can turn on contouring
this will give me a visual snapshot i i
want my entire background filled so i'm
just going to fill
background
now i can drag my solution
my my time slider and instantly see
at any particular time shown on the time
slider i can see the results at that
time
another option i have is to just play
the time slider and let it run on its
own
i'm going to set the playback to every
one second once i hit play
you'll see the trains are dynamically
moving and the results are adjusting
every second so the simulation and
animation on the one line makes it very
easy to see the results
as the trains are moving from station to
station so i see the bus voltage is set
at 99 percent right now
we have a highlight of activity coming
from the energy management system
we know that the battery is going to
discharge if dc bus 4 is less than 100
so we see the discharge
current we see the discharge rate and we
also see some current going
up into the inverter from the feeder and
that's due to the regenerative braking
of some of the particular trains in the
station
but you do notice once we hit 100 the
battery is no longer discharging
as set in the battery the battery energy
storage management system
we can also take a look at the events we
set in the study case editor
so we set switches to open at 00 9am
those
events are tracked in the in the
traction power time slider
we can move forward through particular
uh time stamps i have it set every 10
seconds but this is user defined
so you can set how often you want the
time slider to move
forward reverse or event based
and we can pause and at any time we can
open the display options and
decide which values we want to display
on the one line
for the results currently i'm showing
the the train
of energy i'm showing tractive effort
and neck acceleration i can easily just
change it to route
and in this case we see the speed
location and distance from the train
station
and the grade which is essentially the
incline right now it's pretty nil
but you can see the distance from the
the last station and the speed at which
the chain is traveling so as it arrives
as it arrives towards its destination
you'll see this train decelerate
since this train has arrived at the
station it's now stopped and showing
zero kilometers per hour
the results are calculated throughout
the entire network
so we can view the transmission system
and even as the change
as the trains are moving we can clearly
see the the flows
throughout the transmission substation
are are moving
are dynamically updating we we look at
the current flows being fed through the
transformers
and this is a unified ac dc
engine so again as the ac transmission
is
is being affected by the dc traction
system all the flows are being updated
now that we've run the simulation and
the studies let's take a look at the
plot options
so essentially i can select the train
9517
i'm going to choose to plot the speed
energy
location and distance the results we saw
in the one line however as you see in
the list
there are many many different result
types we can plot from
i'm also going to select to plot the
battery and show the current from the
battery
rectifier 11 and from the rectifier
we're going to plot the average demand
rolling demand and peak demand and i'm
going to select to combine the plots
you can either show them on their
individual xy coordinates of their own
plots or you can combine them into one
plot showing all so the first one i'm
pulling up is the rectifier
you can see the rectifier demand so we
have that the average demand
in purple and the rolling demand in red
and the peak demand in green
as shown now when i click any of those
results that plot disappears so you can
you can click to hide it or to activate
it
next plot is the train we we plotted
train 9517
we decided to show the speed kilowatt
hour location and distance
so we can see on the y-axis that we do
have those we have distance speed and
energy showing
we can zoom in from the bottom at any
particular spot of time
so the bottom allows us to zoom in
another way to zoom in is by just
selecting a specific area
so if you select this region it'll
automatically zoom in and you can double
click to zoom out
or we can just drag and the final plot
we wanted to look at was the battery so
we see the current we can see when it
was charging
and when it discharged across the axis
and again zoom into any particular
region these plots are extremely nice
you can have them in dark mode you can
keep the labels on and off
or you can have them with a white
background and on the bottom left corner
you see the configuration and the report
type now
in a different project i ran for
multiple sets of days so this provided a
3d data 3d
plot because now i have three three
points of references i have the current
and then i have time and day so
etap etrax allows us to plot in 3d
and it and we can zoom in we can zoom
out we can scroll around the 3d plots
wherever your mouse touches the plot
you'll see the results of those
coordinates
so we see x y and z at that particular
location
these plots are are very nice way to
view the results for traction power
systems
and the heat map is generated for
alarming so we see that the red
is showing for alerts
and then we have yellow for marginal and
the remaining items are in blue
now we also have live plots so as i run
the simulation
with these plots activated
the results of the plots will fill as
the simulation runs
so right now on the battery on the
current we can see the discharge
and now that the train 9517 has kicked
in
the results are dynamically updating
live with the simulation as the train is
running
and wherever you place your cursor you
can see the result the result points at
that particular location so these are
live
plots you have the option to copy this
plot to clipboard as an image
to put it on any deliverable you can
export all the data points to excel
you can export the plot as an image or
print directly from the plot analyzer
that train is done with the results we
can also see the battery is continuing
to charge and discharge throughout
the whole time stamp that we selected to
run from 8 20 am to 12
15.
and finally you can also take a look at
any of the results
through the report manager if i select
any report type you'll see we have a
plethora of excel reports to choose from
with all the results tabulated in a nice
easy to read
excel report we have now covered the
trained performance calculation of etrax
and this only included the views the
modeling the train calculation
the unified engine but there are other
expansion add-ons you can add to e-trax
we we looked at the transmission system
we did not however see
the relays that were integrated you can
take the distance and over
current protection and incorporate star
z which is disrespect
distance protection onto your etrax
model and as with etap there are many
different applications that you can
add on to your license so if you want to
do unbalanced short circuit calculations
harmonics
analyze ground grid look at the
underground cabling and do
perform thermal analysis on the
underground cablings in duck bank or
direct buried
and then we will cover soon the traction
scada
power management system capabilities and
for safety
whenever you're doing any changes or
even if you're not you haven't done your
arc flash
you can incorporate ac and dc arc flash
calculations to your
traction model to your transmission
system
and make sure any switch plans that are
provided to the operators can be
simulated within e-tracks as well
successful and continuous management of
data in a digital substation
is a complex process and it requires
orchestration that addresses data
management
training for personnel integration
between systems maintenance testing
documentation
and any change order workflows all these
needs including improving reactive
procedures
slow lagging health indicators crew
delays and restoring outages
unplanned downtime grid failures
ineffective change
management are ultimately impacting the
customer
whether it be a consumer for
distribution company a transportation
station
or a bulk system operator for a
generation plan
there are many reasons for an
organization to embark on a digital
transformation
and it always begins with digitization
we have the digital twin from the design
and planning side
but we want a single source of truth for
the operators
and this provides it because of the
digital twin
you now have information to
look at real-time data on the model the
model can be validated against this
real-time data
and before any expansion projects are
started you will know that the digital
twin you're using to simulate these
conditions
is validated against your as it is
environment
you can also use etaps event playback
for root cause analysis
if you want to look at something that
happened historically you can bring that
back
into e-tracks and re-run simulations for
forensic analysis and replace sequence
of events
you can evaluate switch plans for
restoration or schedule maintenance
and the predictive alarms on this will
prevent any incorrect switching
operations
and we can take a look at simulated data
versus estimated data at non-telemetered
locations
telemeter alarms are very common so when
you have a meter it's very easy and
common to have an
alarm against that equipment that that
is metered
but certain devices don't have meters
attached to them
it is very difficult to get alarms for
non-telemetered devices
but we can use estimated measurements
for non-essential locations
providing us the information we need to
set alarms for this equipment
and these locations this traction power
project
expanded the use of a design model to a
digital twin
which can be used for operation
information
etap contains native communication to
ieds
rtus scada servers and other devices
using industry standard
protocols such as modbus opc ua
dmp3 and iec 61850
this model shows when the switches are
changing position or if a breaker opens
or closes
and is set to display any configuration
change from the field
within the model the meter data is shown
in blue
and is updating at an interval set by
the operator
so you can set it for every second two
seconds the frequency
of the model updates in the real-time
data is operator set
the data in red is state estimation data
state estimation processes telemetry
data such as power measurements
to obtain an estimate of the magnitudes
and phase angle
of the buses at non-telemetered
locations
using state estimation can drastically
reduce
the amount of meters required since
there are only
since they are only needed in critical
locations
using real-time data with state
estimation highlights the areas with
data errors
this helps validate the engineering
model and the scada system together
also the alarm management system is
triggered
for any thresholds or
event changes set by the operator so if
you have
power flow thresholds you can set those
or in this case we see the circuit
breaker trips
set an alarm or returning the switches
back to normal
are another notification and these
alarms can be acknowledged at any time
they can be deleted
they also can be sent via text or email
to to the personnel out on the field
and there's a very easy to use filtering
system so you can filter by device type
time stamps you can look at at different
times to see what alarms triggered at
those particular
during that time period i'm here we're
showing it by
by device type so i can filter per
device to see what alarms were triggered
for that device component name
you can filter by measurement by message
priority so you can set the different
thresholds as a priority based alarm
and then filter by that priority level
the traction scada hmi provides a modern
dashboard
with electrical intelligence and
situational awareness
this is a view of a substation from a
scada screen
this shows the high level connectivity
and signifies any alarms
in a very easy to use interface
we can look at the details of the
substation
i also have one for the train lines so
in this case i'm looking at the train
lines from station to station
and any alarms are immediately displayed
and very easy to identify
another key component to the digital
transformation journey
is an asset management system etap
eprotect
is a centralized enterprise protection
asset management solution
that communicates with field protection
relays
and the etap protection and coordination
modules to manage location
information and settings throughout the
life cycle of protective relays and
substation assets
in this webinar i'm not going to go into
too much detail about each protect
since we have an existing detailed
webinar on our website
but to make sure we understand the
digital journey of a traction power
network i wanted to cover
the asset management system having an
asset management system
increases the data quality by
automatically validating the settings in
your model
against actual field settings
you can manage relay setting changes
with the tools provided
and keep an up-to-date report on
protection system maintenance plans
and these items allow you to comply with
any local regulatory standards you may
need to submit reports to
and all of this information is viewable
on clear defined dashboards provided
which contain critical protection
information
for health monitoring and maintenance
and if you integrate
eprotect with etips advanced fault
analysis system
you can then determine fault types you
can improve
fault location accuracy and this overall
picture provides a thorough assessment
and validation of relay settings
eprotect communicates with the
protective relays via
ftp sftp iec 61850
and retrieves the settings from the
field and passes the as found settings
to the design and protection modules
after the engineers complete the
protection studies the protection
engineers can send their recommendations
back to the eprotect database all this
is done with full documentation on
versioning control
and management which can be viewed on
user created dashboards
the e-protect centralized database can
also download waveforms from the relays
rtus dfrs and store the events
and disturbance records which can then
be passed back to the analysis station
to perform further forensic analysis
this analysis can be done to determine
the accurate location of the fault
this fault location can be used in other
systems such as your outage management
system
or restoration but ultimately the life
cycle management between the engineering
model
and field settings keep your protection
assets verified and validated
for any operation and optimization
decisions
a big part of the job of operators is
education
on the specific project and system that
they're working on
eots which is an operator training
simulator
utilizes the etab digital twin
foundation to provide
operators with an effective learning
environment this is to improve and
augment their knowledge of the actual
system
with a digital twin foundation and
learning environment interfaces for
operators
the interfaces are based on scada
screens pms
or even the oms system the training
simulator provides realistic responses
to actions taken by the operator to
evaluate normal and emergency conditions
this ensures operator readiness for any
current or future conditions
and emergencies whether it is steady
state or dynamic event
having a detailed operator training
simulator allows
operator teams to bring new hires up to
speed in a much faster timeline
here is a quick architecture showing the
flow of information
in the center sits the instructure which
can receive real-time data
from the existing scada it can receive
historical data from the etap playback
service
or simulated data from the etap analysis
machine
from here the trainer can use this
real-time historical
or simulated data to initialize the
trainer's environment
the trainees then can run through the
training plan performing
operator actions and seeing the system
responses by the digital twin
all while operating on the various scada
interfaces
finally the trainee's actions are sent
to the trainer for review
the etap quality assurance program
ensures that our software meets the
highest standards and regulations
whether it's our arc flash software
traction power software or power
management system
etap is thoroughly verified and
validated
e-track specifically is validated
against field measurements provided by
projects and industry standards
including cases within cenelec en 50641
both ac and dc traction power analysis
have been verified and validated
this plot is showing the results versus
field measurements of total energy
this was done for mrvc a mumbai railway
project
etrax is used for many different types
of railway projects
including ac railways dc metros
high speed rail freight heavy rail light
rail
signaling systems consulting firms many
consultant firms are using e-tracks for
these projects
universities research and rolling stock
manufacturers
why do our clients use etap so we've
talked about many of the reasons here
today
but in summary from a technology
perspective
the advanced technology provides an easy
to use graphical user interface
a synchronized gis in one line diagram
an integrated ac and dc analysis
solution
multi-dimensional database for unlimited
scenarios
interfaces with other applications and
attraction e-scada for real-time
predictive analytics
so in summary etrax is becoming the
global standard for traction power
systems
centralize all your information from
planning protection and operations
into one digital twin model this will
help
with improving train performance
optimizing substation capacity
analyzing unplanned events on electrical
demand
and eliminate any estimation using
real-time data
with a verified and validated solution
