摘要: There is disclosed a protecting apparatus for secondary excitation type variable speed AC generator/motor having primary winding connected to an electric power system and each phase of which excited by independent converter unit. The arranged detect electrical event includes at least one overvoltage overcurrent appearing the generator/motor, decide whether detected meets predetermined condition close, when in respect any phases decided as meeting condition, switch circuit corresponding winding.
