摘要
针对于变速风力发电系统中的逆变器,提出了谐波消除(Harmonic Elimination简称HE)、电流滞环(Current Hysteresis简称CH)和空间矢量(Space Vector简称SV)三种PWM控制策略,并对三种方法进行了具体的分析和比较,最后还对这三种方法进行了仿真研究,结果证明了理论分析的正确性。
The paper puts forward control strategys of Harmonic Elimination, Current Hysteresis and Space Vector based on variable-speed wind generation inverter. Moreover, the paper analyzes the three methods and compares them each other. It is, at last, investigated with simulation, and the results proved that the theoriotical analysis are true.
