摘　　要：介绍了双馈感应风力发电机组发电系统的原理,针对虚拟惯量控制通常给系统带来的频率恢复时间变长以及频率二次跌落现象,文章提出一种通过双馈感应风电机组为系统提供频率支撑的新策略,并在Matlab/Simulink仿真软件上搭建了双馈感应风电机组发电系统模型,仿真结果证明文章所提出策略能够在有效提高电力系统频率的动态响应性能的同时,避免频率的二次下跌。The principle of DFIG power generation system is introduced and three kinds of frequency control technology which include the pitch angle control, maximum power point tracking control and virtual inertia control are analyzed at first.And then, aiming at resolving the problem of longer frequency recovery time and secondary drop phenomenon resulted from virtual inertia control,a new strategy of power system frequency support provided by doubly-fed induction wind turbines is proposed.In the last, the model of DFIG power generation system is build by MATLAB/Simulink software.The simulation re- suits show that the proposed strategy can effectively improve the dynamic performance of the power sys- tem frequency response and avoid frequency secondary drop.
