电力系统断路器遮断容量实时校核

Real-time check of circuit breaker interrupting capacity in power system

介绍了基于EMS的短路电流实时计算与分析,叙述了几种典型接线方式下,流经断路器的最大短路电流的求取原则,并说明了断路器遮断容量校核的方法和标准。

The real-time calculation and analysis of short-circuit current based on EMS were introduced. The cal- culation principle for maximum short-circuit current flowed through the circuit breaker under several typical connect- ing modes was expatiated. The method and standard for checking circuit breaker interrupting capacity were explained also.
