Transcripts
hello there in this lesson we would like
to do the load flow analysis for
different loading categories okay so now
we have our system which we discussed
before now I would like to add for
example three loops okay instead of
having two loads we would like to add an
extra one so remember that we had a
template for this load so we can click
on get template same template number two
then okay okay you can do this but of
course we don't have the values of zero
so we can delete this one and select
this like this right click copy then
paste then take it like this and connect
this point to the passport okay so now
we have a swinging loads
now what's the next step the next step
is that we would like to do the load
flow for a different loading categories
so if we go to that load flow analysis
okay and you will see that here a prompt
here click on run load flow okay the
name for example load flow 1 ok I will
just copy this then ok so now this is a
load flow analysis for what for the
design procedure ok if we go back to the
edit mode go to the loads click on load
and go to the nameplate your fan tears
that loading category for the load
itself you will find we have the design
the loading which is hundred percent in
the design and this is the megawatt
negev are produced in case of the motor
load and the static load and we have
here's a norm
which is assumed as a hundred percent we
have the break when two loads on a load
and etc now for the winter okay for
example the winter we will assume for
example 70% okay and for that someone
let's assume 90% okay as a loading
factor winter 70 summer night then click
on ok second load complete assume that
during winter we will assume for example
80 and during summer 95 okay for the
third route we will assume 50 and some
load night okay so now we what did we do
now we for each of these loads we
provided the values in case of summer in
case of winter for each of these loads
during the summer it will be loaded for
example by 70 percent during winter will
be 50 percent okay according to the
values we have what is the benefit of
this we do the load flow analysis for
different periods or different
categories now what if I would like to
edit the name you can go to the project
then settings then loading categories so
here you can rename any of this loads
for example if it is not winter in it
any other time a spring for example you
can edit this and type spring so in each
of these loads you will find that number
four is a spring load okay okay now
forces generator double click on
generate rating then you'll find also
the design normal and emergency for
example we'll assume that
for the stone the boy case for example
not this one not the mega wall not the
voltage is a megawatt for the megawatt
instead of 1 megawatt we will assume a
point setting ok 0.7 megawatt ok so now
we have for the three loads summer load
and winter dude and for the generators a
normal mode or design mode and second
one is a standby mode okay what is the
next step go to the load flow analysis
then run load flow analysis ok you will
see that here this is one which you
already do load flow number one in case
of the normal condition now what if I
would like to do it for the winter for
example how can I do this simply go to
the case study here edits the case of
study or study case ok then go to that
loading you will find here that loading
category this loads a three loads they
are operating in the design mode for
example I can choose that winter load ok
and ok now go to sow want then those a
load flow analysis and name it as number
two ok now this is the values in case of
what in case of the winter okay we do
now the root analysis for the loading in
winter if I would like to do it in
summer go here click here then it case
study loading make it summer load okay
then run load flow name it as number
string okay now you'll see that the
values it changes as if we are in some
ok this is our summer values
okay now what if I would like to make
this generator here you'll see that the
generator here this generator is
producing one megawatt which is a design
value which we put inside the program
okay one megawatt as a value okay but if
we operated it in the the in the standby
mode we will have a whole point megawatt
as I remember I entered 0.8 so let's see
what will happen if we operate in the
loading category of the stand deploy so
go to case study edit study case or
whatever it is then go to loading then
generation category I choose it has a
standby mode I would like to see the
load flow inside the system in case of
the standby mode click on and loading
category for example went okay anything
you would like okay then run load flow
name it as number four okay now let's
see what happened to the generator the
generator is now providing point seven
megawatt okay instead of what instead of
one megawatt why because in the standby
mode we input the value as 0.7 mega watt
okay so we learn it in this video how
can we do the front case studies
according the tools that loading
category is it in summer winter is it in
the design mode in the normal mode
whatever it is fall down in emergency
according to your own category you can
do the load flow analysis and see the
alerts inside the system
