摘　　要：风电具有随机性和间歇性,大规模风电接入会对电力系统安全稳定运行产生较大影响。提出了一种适用于大规模风电接入后系统静态电压稳定性的分析方法,该方法在常规连续潮流的基础上,考虑了网内风机由于低电压穿越能力不足而脱网对系统静态电压稳定的影响。将所提模型和方法应用于含大型风电场的某省级电网静态电压稳定性分析,结果验证了所述方法的合理性和有效性。Due to the stochastic and intermittent characteristic of wind power, large-scale wind farm integration has a great impact on the power system stability. An analysis method on static voltage stability of system with large-scale wind power integration is proposed. This method considers the effect of low voltage ride-through ability inadequacy of wind generator on system static voltage stability based on the conventional continuous power flow. The method and model proposed are applied to analysis of a provincial power network static voltage stability with large scale wind farm integration and the results verify its validity.
