基于配电网拓扑结构聚类的设备改造分区划分研究

目前,配电网设备改造计划安排主要依据设备的健康水平、运行年限等指标,改造项目间的协调优化尚有欠缺,分散无序的改造会导致配电网运行存在安全隐患。提出设备运行状态评分指标,利用改进凝聚聚类分析技术对配电网设备改造需求进行分析,用配电网拓扑结构联络关系作为约束判据,将需要改造的设备进行聚类分区划分。算例分析表明基于配电网拓扑结构聚类的设备改造分区划分方法优于传统的设备改造计划安排,能够统筹设备改造各类影响因素,为改造项目时序安排提供有效依据。

Area division research of equipment transformation based on distribution network topology

Equipment transformation programs primarily depend on the health level, operation life and other indicators of equipment. And now, it is still lacking of coordination and optimization between these transformation projects. This paper uses agglomerative clustering technology to analyze the transformation requirements. A marking index of equipment operating status and contact relationships between equipment are proposed as constraints to cluster the data of transformation. The experimental result shows that the partitions of equipment transformation divide method, which is based on distribution network topology, is better than traditional programs. It provides an effective basis for the transformation projects.
