中文摘要：

以双馈风力发电机DFIG（doubly-fed induction generator）网侧变换器滞环直接功率HC-DPC（hysteresis controller direct power control）和基于空间矢量调制SVM（space vector modulation）的预测（predictive,P）直接功率控制（SVM P-DPC）的性能比较为研究目的,采用理论分析与实验验证相结合的方法,根据网侧变换器的数学模型,分别采用HC-DPC和SVM P-DPC策略,对提出的2种策略进行对比实验。实验结果表明：两种策略均具有快速的动态响应能力,但HC-DPC输出电流和输出功率谐波含量高;SVM P-DPC输出电流正弦度好,输出功率波动小,同时具有良好的静态和动态特性。验证了所提策略的可行性和正确性。

英文摘要：

Comparative study between hysteresis control direct power control （HC-DPC）and predictive direct power control （SVM P-DPC ） for the grid side converter （GSC） in doubly-fed induction generator （ DFIG）-based wind energy generation system is regarded as study object in this paper. HC-DPC and SVM P-DPC are proposed based on mathe- matical model of GSC. The method of theoretical analysis and experimental verification are used. Experimental platform for doubly-fed wind power system is set up to test the proposed control strategies. The experimental results indi-cate that both HC-DPC and SVM P-DPC have good dynamic characteristics. But SVM P-DPC has better static perfor-mance than HC-DPC. Experimental results confirm that the control strategies are feasible and efficient.
