Hello, I am trying to observe the governor response following a generation loss event of around 2000 MW. for this at first I sum up all the PELEC of all the generators(except the unit which tripped) in no-fault condition and get a curve of the accumulated PELEC. then I create that generation loss event and sum up the PELEC of all the generators again (except the unit which tripped) and get a curve of the accumulated PELEC. Then I subtract the old curve from this new curve to get the governor response. But thing is that the governor response is too high. For the loss of 2000 MW, I am getting governor response of 80,000 MW. So I assume I did any mistake in the procedure. So what should be the correct way to plot governor response?

Select Subsystem Power Total for All Buses. This will add five channels with total PMECH, PELEC, PACCEL, PLOAD and PE-PL for all generators. Channel PMECH FOR ALL BUSES shows the the total turbine power in MW.

An example with trip og generator 3018 in savnw network: image description

After trip of generator 3018 the total PMECH is 3185.7 MW. At the new steady state the turbine power is 3266.4 MW. The total governor response is 3266.4-3185.7 = 80.7 MW.
