I'm a total noob when it comes to one-line diagrams and power system modeling. I'm using PowerWorld Simulator to create a simple model of my college campus' electric grid (as an independent project) and am unsure of how to model a few components in the one-line diagram. Any help will be greatly appreciated.
The first screenshot (on the left) contains two symbols I'm unfamiliar with. "Chiller Starters" is next to the first symbol (box with an x through it) and is followed by a circular symbol. Are these chillers, and should they be modeled as loads? If so, how can I find the MW/Mvar values?
The second screenshot (on the right) contains a transmission line connected to a node with three loads. I was told that the "45E" and "65E" next to each fuse is the maximum current capacity for the line proceeding from the fuse. To determine the MW value for each load, I multiplied this value (45 amps or 65 amps) by the load voltage (I was told this is 208 V). But I realize that this simple V*I calculation only yields the apparent power, where I want the real and reactive power values. How do I determine these values? Would I need to use the 500/112.5/75 KVA values next to each transformer (the transformer capacity)? Or will I need to request the MW & Mvar values from campus facilities?
Again, thanks in advance for any insight you can provide.
