Transcripts
hey everyone in this lesson we would
like to discuss how to do a simple
single line diagram in each program so
in order to do a single line diagram we
will use all of our elements inside here
for easy measurements and DC now first
step is that we can add our elements in
this white port or we can activate the
grid in order to see all of the lines or
align all of our elements so in order to
activate the grid you can see here this
small sample show grid lines so that you
can simply align all of your elements
easily inside a tab now what is the
first step first step we would like a
grid ok a power grid you'll see here we
have here a power great click on it one
click then go anywhere one click and go
anywhere for example here like this ok
now another thing I would like a
transmission line you will see here is
this one a transmission line click on it
then put it like this ok now we need a
transformer so if you go here you will
find here a 2 winding transformer click
and put it here for example another
thing we would like Lambeth load or a
cable cable at first if we go here you
will see this one impedance this one is
our cable click on it then put it for
example here ok then we need our load
for example we'll choose a long bit load
so the run bit load will have a sample
of this one ok one click and would it
anyway for example here now we have the
power grid providing power through
the transmission line then this
transmission line will go to a
transformer a step-down transformer for
example then giving this a cable coming
from the transformer to our loot okay
so we need to connect all of these
elements using passports so you'll see
here a pass one click and you can see
here for example like this so we have
only one bus okay we don't have any bus
you'll see the mouse only here but I
would like to add a pass power here
which is this one another one after the
transmission line which you connect this
between the transmission line ends a
transformer and honest up a spot here
another pass bar here so in order to do
this instead of just one click and doing
it every time we have a very simple
solution you can double click on the bus
power okay double click then go anywhere
for example here you will see that I
have now the past power ok again so I
can put it like this another one here
and so on now if I finished my using the
power you can click on the mouse ok now
we need to connect to the elements you
will see that here this is a power grid
when I come close to it it becomes a
paint color click on it and drag click
and drag in order to connect it anywhere
you'd like
I would like to connect it to passport
number one you will see that when I come
close to passport number one when I
select it you will see it becomes the
paint means it is connected to it so
leave the mouse they are connected to
each other take this one and drag and
connect take this one and drag to
connect take the transformer and connect
take this transformer ok we need to move
this click and drag in order to move the
world
okay click this one and put it here
click this one and move it here okay and
you can do another thing you can click
on the cable and for example move toward
the Z pass you'll see that it becomes
pink means they will connect then leave
the mouse so they are connected you can
select and drag like this and move it as
you would like okay
the Lambuth load like this okay so now
we have a power grid through a
transmission line power transformer then
underground the cable for example to our
load now if I would like to align all of
these elements together I will select
all of these elements then right click
then alignment then you can choose any
alignment form you would like as an
example I will choose this one okay this
a line you will see that here this one
sees a written word here or written
sentence here okay
alignment you will see that here it says
align selected elements in vertical at
the central location of the anchor
element they add the element which I
selected okay so if I click like this
you will see that now all of the
elements or send art together
okay now we would like to do another
sync if I would like to add another
cable and root okay or save this one as
a template in order to use it several
times so I can click like this and
select this two elements which is the
cable ends along bedload then you will
see that here there is upward here an
option called get done plet or add to
only V template one-line view template
add to one line view template like this
you will see that here it tells you to
save stemple
it as you would like for example I will
call it template number 2 ok and save ok
following a wall generator successively
add this extension ok now what is the
next step if I would like to add more
than one cable end lumbered load simply
go back get template ok and you see
template number two which is a cable and
long bed load then ok now we will find
here this is the element which we saved
before okay very nice so we can take
this and add it like this move it like
this select and move okay and we can do
a nice thing to zoom in like this ok
let's go down order to see all of our
elements ok so get the mouse now what is
the next step
now what if I deleted this element for
example delete this one ok you will find
that the template when I selected this
one all of the components are selected
together why because they are a template
now right click and click ungroup okay
so this element you can select it alone
or this element or even the passport so
for example if or how it deleted the
long blood like this click on delete now
if I would like to get it back you will
find it in here system dumpster click on
it you'll find here this is the one
which we deleted before okay
this load now you can control see then
get back to the online diagram and
control V now I got back the element
which I deleted
okay I copied it from that system
dumpster and returning it back here okay
now what if I have a very larger system
okay a very large system and I would
like to add it as a network
okay so network composite which is a
here composite network one click and
click anywhere so find its called
network number one okay okay now I would
like to connect it to this pass bar we
can click on this pass bar and extend it
like this okay click and drag for
example now I will connect it for
example to this point okay now if I
double click on the network you'll find
it is having a four point one point
connected to pass three they left the
point the right one and the bottom point
okay it has four points the upper the
lower the Aza bottom right and the left
you will find that the upper one is
connected to post number three let's get
back window and only v1 edit it okay if
we get back you'll see that here the
upper one is connected to post number
three exactly as it says inside the
network now we can double click the
network in order to add any line diagram
we would like another line diagram if it
is a very large system okay so we can
click on get template for example we'll
use this loot okay and we'll connect it
for example to the bottom one okay or
not the bottom one we will connect it to
the upper one like this okay so what
happens here okay let's move this so
what happens here is that this load is
connected to the upper point and the
upper point is connected to passport
number three so if we get back window or
le v1
you'll find that this point is connected
to the upper point of the network which
is connected to our loot okay so from
this you can add several elements inside
the network and connect it to this point
or this point or this point and getting
back to our Oh le V we can use this
point or this point of this point to
connect it to a different elements in
the power system so in this video we
learn it how to do a simple single line
diagram
