矢量控制在双馈风电网侧变换器中的应用

Space Vector Control Used in Wind Power Doubly-fed Induction Generator Grid Side Converter

提出一种双馈风电系统中网侧变换器的设计与控制方案。首先,根据网侧变换器原理设计控制策略,控制策略采用d,q轴控制;其次,介绍了空间矢量脉宽调制(SVPWM)的一般实现方案,并根据TMS320F2812提出了一些改进;详细介绍了系统的软件设计;最后给出实验结果证明了该方案的可行性和有效性。

This paper proposes based on the design and control of doubly-fed induction generator system grid side con- verter.At first,according to the principles of grid side converter the control strategy is desisned which uses d,q axis control.Then general method of space vector pulse width modulation （SVPWM） is introduced, which is improved based on TMS320F2812.The software design is presented.At last,the experimental results prove that the method is available.
