    摘要:

    各地配网自动化建设尚处于大规模试点阶段,很多区域的故障信息感知和定位手段有限,不同性质的停电事件又来源于多个业务系统,在条件有限的情况下实现停电事件精准分析的需求尤为迫切。本文结合电力公司的停电管理实际业务流程,设计停电池功能,综合分析变电站、馈线、台区、用户多层主配网数据,在分层分级研判基础上建立信号可信度模型,结合证据理论算法(Dempster/Shafer,DS)融合分析,多维度灵活地挖掘分析停电事件,提高故障点定位的容错性,满足在差异化场景下构建可靠的结构化停电信息资源池实现数据的共享发布。

    Abstract:

    The construction of distribution network automation in various regions is still in a large-scale pilot stage. The method of sensing and locating fault information in many areas is limited, and the outage information comes from multiple systems. Therefore, the need to achieve accurate analysis of outage events under limited conditions is particularly urgent. The actual outage management process of the power utilities is considered and integrated in this paper. An outage information pool is created. Multi-layer data of substations, feeders, distribution transformer areas and customers scattered in transmission lines and distribution lines are analyzed comprehensively. Information credibility profiles are established based on hierarchical analysis. Dempster/Shafer evidence theory algorithm is used to analyze outage events flexibly from multiple dimensions. The method in this paper effectively increases the fault tolerance of fault location, and also enables information sharing and releasing by establishing a reliable structured outage information pool under different conditions.
