摘　　要：为了解变耦电抗式可控串补的各种操作特性,对串补装置典型操作时的电流、电压进行了试验和分析。提出用于串补装置暂态分析的通用等值电路,利用特性参数建立电路方程解的通用结构。利用特性参数法分析线路开关投入装置时的过流、过压,以及装置在逐级和大跨级调节换级过程中的电流、电压特性。采用电磁仿真软件EMTDC对旁路开关投、退串补装置的操作过程进行了仿真;还进行了动态模拟试验以及装置在典型换级过程中的电流、电压的特性测试。结果表明和理论分析是一致的。In order to understand the various operational characteristics of TCSCAC （Thyristor Controlled Reactance Series Compensation by Adjustable Coupling）,the current and voltage during the typical opera-tion of TCSCAC device are analyzed and experimented. Its general equivalent circuit is proposed for the transient-state analysis and its general frame of circuit equation solutions is built with its charac- teristic parameters. The over-current and over-voltage during device switch-on operation and the current and voltage characteristics during one-step and multi-step regulations are analyzed. The operational pro- cess of device switch-on and switch-off by bypass switch is simulated with EMTDC software,the dy- namic simulative tests are carried out and the current and voltage characteristics during typical tapchanging process are investigated. The test results accord with the theoretical analysis.
