摘　　要：基于PSD-BPA软件搭建了风电并网典型仿真模型,针对风电系统中经常出现的低频振荡和低电压穿越现象,通过仿真计算,分析了动态无功补偿装置对于提高电网动态稳定性的作用,对3种不同类型动态无功补偿的控制效果进行了比对分析。This paper establishes a typical wind power integration model based on power system simulation software PSD-BPA. In order to solve the problems such as low-frequency oscillation and low voltage ride-through existed in the wind farm integration, the paper analyzes the effect of dynamic reactive power compensation on improving the dynamic stability of power system-connected wind power through simulation calculation, and comparatively analyzes the control effect of three different kind of dynamic reactive power compensation.
