摘　　要：为使风电并网后的能够稳定运行,从双馈风电机组的自身特点为角度分析双馈风力发电并网对电网系统稳定性的影响,以Matlab/Simulink为平台搭建风电并网的模型,模拟仿真双馈风机在三相故障时加入两种无功补偿装置后的情况,比较得到最优的无功补偿装置以改进风电在并网时的稳定性。结果表明,静止同步补偿器在提升风电并网电力系统稳定性比SVC静态无功补偿器方面有更好的效果。In order to enable the stable operation of wind power grid connection,from the perspective of the characteristics of doubly-fed wind turbines,the influence of doubly-fed wind power grid connection on the stability of the grid system is analyzed,and a wind power grid connection model is built and simulated on Matlab/Simulink platform.Simulate the situation of adding two kinds of reactive power compensation devices to the doubly-fed wind turbine when the three-phase fault occurs,and compare the optimal reactive power compensation device to improve the stability of wind power during grid connection.The results show that the static synchronous compensator has a better effect in improving the stability of the wind power grid-connected power system than the SVC static reactive power compensator.
