I was thinking that because xL = jwL, inductive reactance would go down as frequency decreases. And as current will be staying the same, there will be less inductive reactive power (VAR). Then, I figured I would need less capacitive reactive power to compensate.
I'm converting a first generation, fixed speed wind turbine from 60Hz operation to 50Hz operation. There are passive PFC capacitor banks in the downtower box on the turbine. How are the capacitor banks derated for 50 Hz operation? Is it as simple as, for example, downsizing from 15 to 12.5...
