摘要
本文以双馈风力发电系统为研究对象,建立了双馈风力发电系统的动态数学模型,包括风速、风力机、双馈发电机以及补偿电容器四个部分。利用Matlab/Simulink建立了仿真系统模型,详细论述了仿真的方法和过程,并对风电场接入电力系统进行了动态稳定分析,论文同时就如何提高风电系统短路故障后的动态稳定性进行了研究。
Taking doubly-fed wind power system as an object, the paper presents the dynamic model of doubly-fed wind power system, including wind speed, windmill, doubly-fed generator and capacitor. The method and process of the dynamic simulation based on Matlab/Simulink are discussed in detail, and the dynamic stability on the wind-farm connected to power system is analyzed. At the same time, the thesis studies how to improve dynamic stability of wind power system after the short-circuit fault is occurred.
