| Abstract: | Seeing that the open-phase protection for generator circuit breakers of 660 MW units in Shajiao C Power Station has only alarm circuit but no trip circuit, this paper analyzes the problems of the generator circuit breaker protection, and puts forward corresponding amelioration scheme. The scheme takes under advisement the function realization, protection configuration and misoperation prevention, etc., thus optimizing the open-phase protection for generator circuit breakers. |
