针对风电场并网带来的电压稳定性问题，以双馈风电机组为研究对象，根据双馈风电机组的运行特性，对风电机组的静态电压稳定和暂态电压稳定进行了理论分析，在Matlab／Simulink中建立了双馈风电场并网系统和静止无功补偿器模型，通过绘制双馈风电机组的P-V曲线，研究随着风电场出力的增加，电网静态电压稳定性的变化情况，并通过仿真验证了静止无功补偿器对于改善风电场并网系统的静态电压稳定性和暂态稳定性的作用．

With the proportion of the installed capacity of wind farm in the grid increasing, the impact of wind farm on the power system voltage stability becomes obvious. Based on the operating principle, the paper, studied the doubly fed induction generator as the object, and analysed the steady voltage stability and transient voltage stability of DFIG. Models of the wind farm system connected into the power grid and the static var compensator were established in Matlab/Simulink environment. According the simulation re sults, the P-V curve was drawn, so the voltage changes with the output power increasing can be observed. The simulation results show that SVC can improve the steady voltage stability and transient stability of wind farm.
