Revision history [back]

I have a REPCTA model with the frequency droop enable, Fflag=1 and Dup=0 and Ddn=0. therefore, during a system frequency test the power does not response increasing or decreasing power as TSO comments: "The expected response for the generator would be for the real power output to remain constant during this simulation."

The TSo has tested Frequency response test too: "Low and high frequency conditions are imposed at the generator's point of interconnection". I imagine that the changes in frequency are perfomed at generator's bus deleting the REPCTA module. Is it correct? I have set a playback connected to the genertor bus by a ideal line and modified f between 60.2 and 59.8HZ but active power does not change. I have not seen anything in REECA linked to frequency. Nevertheless, the TSO has showed me a plot in which P changes. How is the test perfomed at the machine level?
