省级配电自动化主站的停电信息资源池功能设计

各地配电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信息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。文中结合电力公司的停电管理实际业务流程,设计停电信息资源池功能,综合分析变电站、馈线、台区、用户多层主网和配电网数据,在分层分级研判基础上建立信号可信度模型。结合DS证据理论算法融合分析,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。

Function Design of Power Outage Information Resource Pool for Provincial Distribution Automation Main Station

The construction of distribution automation is still in a large-scale pilot stage. In many areas, the means of fault information perception and location are limited. The information of different power outage events come from multiple business systems. It is particularly urgent to achieve accurate analysis of power outage events under limited conditions. Combining with the actual business process of power outage management of the electric utilities, this paper designs the function of power outage information resource pool, comprehensively analyzes the data of multi-layer main network and distribution network of substations, feeders, distribution transformer areas and users, and establishes the signal credibility model on the basis of hierarchical study and judgment. Combining fusion analysis of DS evidence theory algorithm, multi-dimensional flexible mining and analysis of power outage events, the fault tolerance of fault location is improved, and a reliable structured power outage information resource pool is built to achieve data sharing and publishing in different scenarios.
