摘　　要：针对双母接线形式下的母差保护装置互联启动原因进行了详细分析,根据双母接线变电站出现的互联启动异常情况,综合母差运行方式、继电保护装置等信息因素,对母差保护进行动作行为的深入探究,提出了非正常启动方式下,母线保护装置互联启动分析流程,总结出母线差动保护装置中互联装置启动逻辑关系,对防止保护发生误动或拒动提出了有效的解决方法和运行方案。The paper analyzes the cause of the interconnected startup of bus differential protection device with double bus in detail. According to the abnormal interconnected startup in double bus substation, combined with the operation mode of the bus differential protection and the information of relay protection device, the paper studies the action of the bus difference protection, proposes the analysis process of the abnormal interconnected startup, summarizes the logical relation of the interconnected action, and puts forward the effective solution and operation scheme for avoiding the protection misoperation or failure.
