| 摘 要： | 抽水蓄能机组具有四象限运行能力,在电网调峰中发挥重要作用。山西电网配置有4×300MW的西龙池抽蓄机组,为接纳更多的风电,需要西龙池抽水蓄能电站多台机组抽水运行,由此会带来西龙池电站500k V母线电压降低,影响电网安全运行。本文通过仿真分析和现场试验的手段研究了西龙池电站在3台及以上机组抽水工况下,机组发出无功量对机组安全、电网电压及系统稳定性的影响,给出了机组运行的最优无功值。

| Abstract: | Pumped storage power plant can run at four quadrant operation, which plays an important role in the peak load regulating of power system. More than two units of Xilongchi power plant need pumping operation to improve wind power integration ability. Then the 500kV bus voltage of Xilongchi will be lower than normal level, having impact on the safe operation of power grid. The units safety voltage level and stability of power grid is studied by simulation and experiment. The optimal reactive Var of every unit is presented. |
