Abstract

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.

Description

technical field [0001] The present invention relates to a megawatt-level multifunctional wind power generator energy-saving control device, which belongs to a kind of three kinds of wind power generators commonly used at home and abroad: direct drive permanent magnet generator, doubly-fed generator and asynchronous induction generator , An energy-saving control device that can reduce power generation costs. Background technique [0002] At present, the world is facing huge challenges in terms of resources, environment, energy conservation and emission reduction. Experts at home and abroad estimate that in the next fifty years, whoever masters low-carbon technology and renewable energy technology will master the world. Wind power is undoubtedly an important part of renewable energy technology. In the control technology of wind power generation, the pitch control technology and motor speed control technology are the core of the key technology. The quality of the output powe...
