摘要
基于8XC196MC单片机的双馈风力发电机组控制系统,由两个不同变流器、复合斩波器、双馈电机、8XC196MC微控制器系统等组成。运行时机组的两个控制环同时工作,实现变速恒频。低于额定风速时,通过整流器及逆变器控制双馈异步发电机的电磁转矩,实现对风力机的转速控制;反之采用节距调节的方法除去多余的能量。
The control system for double-fed asynchronous wind-driven generator based on 8XC196MC microcomputer is made up of two different converter, complex chopper, double-fed generator, 8XC196MC microcontroller. Two control ring work together to realize variable speed constant frequency. When being low specified wind speed, the electromagnetic torque of double-fed asynchronous wind-driven generator was controlled by rectifier and inverter to realize the speed control of wind generator. Contrariwise, supperfluous energy was removed by using festival square regulation ways.
