Energy-saving control device of megawatt level multifunctional aerogenerator

The invention relates to megawatt multifunctional wind-power generator energy-saving controller, especially for normally used three kinds of wind power generator as direct driving permanent magnet generator, double-feed generator and induction generator, which can reduce generation cost. The inventive megawatt multifunctional wind-power generator energy-saving controller consists of controller and speed meter, insulated grid diode-triode IGBT switch trigger circuit, controllable silicon rectifier SCR trigger circuit, DC overvoltage protector and two transformers each is separately connected with controller. Rotation speed detection end of speed meter is connected with rotor of controlled wind power generator.
