A nuclear power plant was initially operating at 80 percent power in the middle of a fuel cycle with the main generator connected to an infinite power grid with the following main generator output parameters:
60 Hz
25 KV
300 MVAR (out)
800 MW
A hydraulic oil system malfunction occurred that caused the main turbine steam inlet valves to slowly drift closed.
After 10 minutes, the main generator real load decreased to 600 MW.
Assuming no operator actions were taken, how were the remaining main generator output parameters affected after the above 10 minute period?
