面向馈线的中压配电网拓扑分析

鉴于中压配电网线路和设备众多,但不同线路上的设备之间的联系很少,故将中压配电线路连同相关的设备定义为馈线;从而分段开关将馈线分成若干馈线段,馈线通过变电站出线开关连接到变电站母线上,馈线之间通过联络开关连接,构成供电环网。面向馈线的网络拓扑分析算法为:首先进行馈线拓扑分析,然后通过联络开关进行连接线分析,最后通过变电站出线开关状态分析完成整个中压配电网络的拓扑分析。所提出的方法通过对对配电网络进行分割,缩小了搜索的范围,从而提高了络拓扑分析的速度。

Circuit Oriented Topology Analysis of MediumVoltage Distribution Network

As there are lots of lines and equipment components in mediumvoltage distribution network, but less connection of equipments among various lines, the object "circuit" is defined in this paper as "collection of conducting equipments including lines (overhead lines, cables and related equipment components", thus the distribution network consists of different circuits that are connected with each other through interconnection switches, and each circuit is divided into several circuitsections, and connected to the bus of substation via its outlet switches. The circuit oriented topology analysis method in this paper is as follows: to analyze the circuits first, then the connection lines based on interconnection switches, and finally the whole network based on the onoff states of substation outlet switches. The proposed method has high speed as it devides the network into circuits, and thus the search scope of analysis becomes smaller.
