摘要
电压水平是衡量电能质量的重要指标。随风电场容量日益增加,风电接入电网的规模不断扩大,风电并网的电压问题也逐渐暴露出来。文中利用电力系统分析综合程序(power system analysis software package,PSASP),对不同运行方式下的甘肃电网进行了潮流计算,根据给出的电压调节原则和手段对研究区域110 k V及以上等级越限母线电压进行了调节。在此基础上,通过改变玉门地区风电集群的有功出力研究了其对于系统静态电压的影响,并对出现这种影响的原因进行了分析。
Voltage level is an important indicator to measure power quality.With the expanding scale of wind power and its increasing capacity,voltage problems caused by wind power integration have been gradually exposed.In this paper,PSASP（power system analysis software package） is used to calculate the power flows of Gansu Grid indifferent operating modes and regulate the grade-limit voltage of 110 kV and above voltage levels in a specific study area.On this basis,study the impact on system static voltages by changing the wind farm output in Yumen area and then analyze the reasons.
