摘　　要：为了研究大容量双馈式风力发电系统的运行控制特性,根据双馈式感应电机(doubly-fed induction generator,DFIG)动态数学模型,采用典型控制策略,分别在PSCAD/EM TDC、RTDS仿真平台下建立了4.5 M W双馈式风力发电机系统的动态模型。在此基础上,对风力发电系统在不同风速下的运行控制特性进行了仿真研究。仿真分析结果表明,所建立的大容量双馈式风力发电系统有较好的动态响应与控制特性,与理论分析相吻合。In order to research the operation and control features of large-capacity DFIG system, a 4. 5 MVA DFIG system was built in PSCAD/EMTDC and RTDS simulation environment respectively. Based on the dynamic mathematical model of the doubly-fed induc- tion generator （doubly-fed induction generator, DFIG） and the typical operation control strategies, the simulations were carried out for the opertion of the system under different wind steps. The simulation results show that dynamic response and control performance of the large-capacity DFIG system are satisfied and consist with the theoretical analysis.
