part4/chapter8/sec2-9.11.2:“Alternative suitable protection, such as generator differential protection, which will trip the generator circuit breaker in the event of a fault in the generator or in the supply cable between the generator and its circuit breaker, would also be acceptable.”没有明确提出发电机功率大小。
但CCS和LR等中明确提出“容量为1500kVA 或以上的发电机应配备一合适的保护装置或系统,以能在发电机内部或发电机至其断路器之间的供电电缆发生短路的情况下,使发电机灭磁并使其断路器分断”-通常这种保护以差动保护方式实现。 |
