摘　　要：当前五防闭锁都是基于规则逻辑实现的,这种方式具有诸多的缺点。在基于IEC61850的智能变电站中,分析全站SCD文件中的SSD部分,从中读出一次设备拓扑信息,经归一化处理为双端设备后,构建图论拓扑模型。描述了基于设备类型的防误元规则和拓扑防误的过程。所设计的在线防误以基于拓扑的防误闭锁引擎为主,实现拓扑设备的防误;以基于规则逻辑的防误闭锁引擎为辅,实现非拓扑设备的防误。现场实际运行证明所设计的在线防误系统运行可靠,维护简单。The present five preventive blocking is based on the rule logics,which has many shortcomings. The SSD （Substation Specification Description） of SCD （Substation Configuration Description） of IEC61850- based smart substation is analyzed to extract the topological information of all primary devices. The single- terminal or multi-terminal device is then normalized as dual-terminal device and its graph theoretical topology model is constructed. The element rules of misoperation prevention based on device types and the process of topological misoperation prevention are described. The designed online misoperation prevention mainly applies the topology-based misoperation preventive blocking engines to prevent the misoperation of topological devices while supplementarily applies the misoperation preventive blocking engines based on rule logics to prevent the misoperation of non-topological devices. Site operation shows that,the designed online misoperation prevention system runs reliably and its maintenance is simple.
