摘要
在长电缆供电变电站中,为限制工频过电压和操作过电压,须安装高压并联电抗器。结合洋山110kV变电站的实际情况,分析了高压并联电抗器的限压效果,讨论了并联电抗器接在母线上与接在进线电缆末端两种不同接线对运行操作带来的影响作用。
It is necessary to install high voltage shunt reactor in the substation supplied with long power cables to limit the power frequency overvoltage and switching overvoltage. Based on the practical condition of 110 kV substation at Yangshan island, the effect of voltage limitation by high voltage shunt reactors is analyzed. The influences of two connections, with shunt reactors connected to bus or connected to cable end, on substation running and operation are also discussed.
