针对风电接入点的电网电压稳定性问题，根据宁夏局部电网的特点，对风电接入点的电网电压波动进行研究，结合实际情况通过仿真软件进行模拟潮流计算，验证包含风力发电的不同因素对电力系统电压性能的影响。结果表明：受风电场无功补偿水平、风电有功出力以及接入方式的影响，风电接入点的电网电压随着风电有功出力的变化呈现先上升后加速下降的波动趋势，该结果可为控制风电场接入点的电压稳定水平提供参考。

Aiming at the problem of the access point voltage stability between wind power farm and power grid,according to the characteristics of partial power grid in Ningxia,researches the voltage fluctuation of wind power access point. Combining with the actual conditions,simulates power system tide calculation by simulation software,verifies the influence of various factors including wind power generation system on power system voltage performance. The result shows that:affected by the reactive power compensation levels,the active power output and the access ways of wind power farm,the access points voltage appear the fluctuation trend of first rising then accelerating decline,this result can offer the reference for control access points voltage stabilization level of wind farm.
