摘要
分析了近年来山东电网东部地区500kV变电站的母线电压在低限附近运行,对电网的安全、经济运行带来不利的影响。并定量分析了在高峰负荷下切除部分线路高抗,对500kV系统暂态稳定及500kV变电站电压增加的影响。
The bus-voltage of 500kV substation operates near the low-limit due to the on-going heavy power flow to east,which do harm to safety and economical operation of power network. So the high-voltage reactor is removed in heavy flow to increase the voltage level.
