摘　　要：本文介绍了电网中的两个系统在用某220kV智能变电站220kVⅠ、Ⅱ母联测控同期合母联断路器时所发生的非同期合闸事故,并通过对此事故发生原因以及暴露问题的深入分析,结合测控同期装置的工作原理,提出合理的解决方法,为今后变电站同期合闸的安全操作以及类似事故的分析和处理提供了参考方法。Two systems in the power grid make use of the 220 kV intelligent substation 220 kV Ⅰ and Ⅱ bus joint measurement and control when closing the bus joint breaker in the same period, the asynchronous closing accident occurs. Through the thorough analysis of the causes of the accident and the exposed problems, combined with the working principle of the measurement and control synchronization device, the reasonable solutions to the problems exposed by the accident are put forward it provides a reference method for the safe operation of synchronous closing of substation and the analysis and treatment of similar accidents.
