摘　　要：针对电网发生电压跌落故障时风力发电系统大规模从电网解列将对电网造成严重威胁,为满足风力发电系统低电压穿越技术的研究需要,提出了两种模拟电网电压跌落的实现方法,给出了电路拓扑结构,并在双馈风力发电实验平台上予以实验验证。结果表明,该方法简便、有效、可行,可实现对电网电压跌落模式和跌落时间控制,为风电系统测试中VSG方案的选择和实现提供参考。When power system voltage-sag fault occurs, dramatic wind power generation system detaching will result in serious risks to the power system. In order to fulfill LVRT technology research in power generation system, two methods of simulating power system voltage-sag are presented and the related topological structures are provided. They are verified on the Double-Fed Induction Generation system plant. The results show that the methods are simple, effective and feasible. They can realize the control of the power system voltage-sag model and duration, and provide a reference to VSG method selection and realization in wind power generation system testing.
