电力系统分块网络拓扑法的建模分析

摘要

The traditional topological analysis on the power network often repeats path search.With increasingly large scale of power networks, the network topology is becoming more and more complex,thus displaying slow speed and low efficiency of traditional topological methods which can not meet the requirement of application software of the power system on high efficiency.Therefore,this paper proposes a partitioned network topology and introduces the concept of switch cell,whereby the equipment model is abstracted into nodes and a node adjacency list is established before partitioned network topological analysis is made in line with certain rules established according to the characters of the switch cell.The purpose of updating topology of the whole network is thus attained by re-establishing partial network topology involved in the changes of the network topology when they take place.%传统的电网拓扑分析方法往往重复搜索路径，随着电网的规模日益加大，电网拓扑的复杂程度日益加重，更凸显了传统拓扑分析方法的速度慢、效率低，无法适应电力系统应用软件高时效性的要求。因此，提出一种分块网络拓扑法，引入开关间隔概念，将设备模型抽象成节点，建立节点邻接表，根据开关间隔特点设立一定规则对电网进行网络分块拓扑分析，当电网拓扑发生变化时通过涉及变化的局部网络拓扑重建达到全网拓扑更新的目的。
