How will the value of the output frequency change if the load is removed from a turbo generator having a governor speed droop setting of 3%?

Correct Answer: Option C — It will increase.

Governor speed droop dictates that prime mover speed increases as electrical load decreases. With a 3% droop setting, shedding full load causes system frequency and speed to rise by approximately 3% until the governor reaches its no-load speed setpoint.
