摘　　要：在输电系统短路容量不断增加的情况下,提高等级或更换设备不是解决短路电流超标的较佳方案。介绍了采用TPSC加外接的串联电抗器作为短路电流限制器,以其设计的高可靠性,大利用率以及在美国南加州多个500kV变电站的成功投用,实现了FACTS技术在高压输电系统中对故障电流限制的突破。Increasing the ratings of equipment or even replacing them are not the best methods for solving the excessive short-circuit current, which is due to the increasing short-circuit capacity of transmission system. Adopting TPSC with externally linked series reactor, the short-circuit current limiter with its high reliability, availability, and its successive application to 500 kV substations in South California of USA, helps the FACTS technology break the fault current limitation in high voltage transmission system.
