摘要
介绍了500kV变电站死区故障的情况,分析了加装光电流互感器和加装站域保护这两种应对方案。以500kV杨高站为例,论述了加装站域保护的设备配置方案,介绍了保护装置的外部接口与技术原则,并分析了工程中的注意事项。实践表明,加装站域保护应对死区故障的效果良好。
The circuit breaker failure of 500 kV substation was introduced,and the two countermeasures of adding photocurrent transformer and installing substation protection were analyzed.Taking 500 kV Yanggao substation as an example,the equipment configuration scheme of installing substation protection was discussed.The external interface and technical principle of the protection device were introduced,and the precautions in the engineering were analyzed.Practice has shown that the effect of installing substation protection is an effective way to deal with circuit breaker failure.
