![]() ![]() Additional problem is High Voltage that shows in proximity to the generators.ģ. Constant Model, same issues when I have generators and utility on the same feeder. setting I should chose if setting in the field is not known?Ģ. I can swing this reactive energy flow in the opposite direction, and then it is in the correct direction (relative to the voltage magnitude). Please explain how am I suppose to interpret these results? I noticed that by playing with the generator scheduled voltage in p/u. In all fairness this is happening with models only when I have utility source and generator source on the same model Generator source far downstream of the utility bus). (Generator was set at 1.0 pu, and source at TS was set at 1.0 pu too) I expect that reactive power flow should always be going from higher to lower voltage bus in the system. It is going from source of lower voltage to the source of higher voltage. Problem I have with this is that I noticed Reactive Power Flow is going in different direction that I would expect. I don’t have problem with this, since all generators are exactly working this way in reality. I noticed that when I use PV machine model machine (generator) pumps out as many +/- VAR’s as needed to keep generator terminal voltage at preset value. When are we supposed to use which model and why?ġ. Induction machine with negative active power There are 3 different ways we can model generators in PSS software.ģ. ![]()
