摘要
分析了传统的双馈风力发电控制策略,并在网侧变换器和转子侧变换器中分别使用了电网电压定向和转子侧定子磁链定向的矢量控制。传统的控制策略比较复杂,对其提出了改进方案,改进后的控制方法大大简便。利用PSCAD/EMTDC平台进行仿真表明,改进后的控制方案是正确的。
The traditional control strategy of doubly-fed wind generation is analyzed in this study first. A new control strategy has been proposed in this study with voltage oriented and stator flux oriented vector control in grid side and rotor side of the converter adopted respectively. The traditional control strategy is much complex. The new improved control strategy is much simpler than the traditional one. The digital simulation has been done using the PSCAD/EMTDC platform. The results verify the correctness of the new control strategy.
