Study on the Short Circuit Current Delay Over Zero Factor of Generator Source Based on RTDS

In generator unit, the possibility of short circuit current zero delayed occurred will affect the breaking of the Generator circuit-breaker when failure occurs in the system, and it's an important test of the breaking capacity of the Generator circuit-breaker. This paper obtained the condition...

Summary:In generator unit, the possibility of short circuit current zero delayed occurred will affect the breaking of the Generator circuit-breaker when failure occurs in the system, and it's an important test of the breaking capacity of the Generator circuit-breaker. This paper obtained the condition of the Generator-source short-circuit current delayed using the RTDS, established an arc black box model Generator circuit-breaker Based on an actual engineering of a hydropower station generator parameters and the data of arc voltage and arc current measured in the type test of a prototype Generator circuit-breaker , focus on affect of the generator circuit breaker arc resistance, for providing reference to judging the breaking capacity of generator circuit-breaker.
