【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。
[Abstract]:Voltage level is an important index to measure power quality. With the increasing capacity of wind farm, the scale of wind power connected to power grid is expanding, and the voltage problem of wind power grid is gradually exposed. In this paper, the power flow of Gansu power network under different operation modes is calculated by using the power system analysis program (power system analysis software package / PSASP. According to the principle and means of voltage regulation, the overrun bus voltage of 110 kV and above in the study area is adjusted. On this basis, by changing the active power output of the wind power cluster in Yumen area, the influence on the static voltage of the system is studied, and the reasons for this influence are analyzed.
