摘要
本文对500千伏线路和变压器的运行方式进行了分析,指出在500千伏系统投产初期,总有大量的充电功率过剩,因此,对感性无功补偿应予充分重视,以避免发生高电压现象。文中叙述了华东500千伏系统采用可投切的低压电抗器作为感性无功补偿的主要手段,还对低压电抗器的选型及其接线作了探讨。
The operation characteristics of 500kV lines and transformers show that special attention should be paid to the reactive power compensation to avoid the occurence of abnormal high voltage due to plentiful surplus of charging current on 500kV lines during initial stage. Low voltage reactors, which can be switched on or off conveniently, are used as the main device of reactive power compensation in East China 500kV system. Selection of types and specifications of the low voltage reactors and the connection schemes are also discussed.
