摘要
华电芜湖电厂一期(2×660MW)工程中,升压站为500kV电压等级,采用121断路器接线。启备变接入1(1/2)断路器串中,这使得该工程启备变保护用电流互感器的配置不同于一般的变压器。本文通过计算分析,提出了启备变1(1/2)断路器接线中保护配置方案及电流互感器的选型。
1（1/2）circuit breaker connection of high voltage distribution device is used in the first phase of the project（2×660MW） of Huadian Wuhu Power Plant.The booster stations have 500kV voltage class.Startup/standby transformer is connected in 1（1/2） circuit breaker connection,which makes the relay protection and secondary wiring complicated.By computational analysis and engineering example,a relay protection and current transformer configuration of 1（1/2） circuit breaker connection are proposed in this paper.
