配电网络建模、结线分析及动态网络着色

首先说明现有的输电网络建模方法因为没有考虑到配电网络的特殊结构和配电应用软件的具体要求，所以不宜直接用于配电管理系统，然后提出适合配电网的网络建模方法和数据库设计结构，通过引入一些新模型来描述辐射型配电馈线、馈线段和供电电源，使用户能直观、方便地建立配电网络数据为好配电网络线分析策略，通过变电站开关和馈线开关变位的分别处理，提高了结线分析速度和效率；最后介绍配电网络的动态着色功能及其实现方法。

DISTRIBUTION NETWORK MODELING,CONNECTIVITY ANALYSIS AND DYNAMIC NETWORK COLORING

This paper firstly points out that the present network modeling method for EMS may not be suitable for DMS because the specific structure of distribution network and the requirements of the distribution application software are not considered. Then a modeling method and the database structure suitable for distribution network are proposed. A number of physical models designed deliberately for describing distribution feeders, feeder sections, supply sources etc. are introduced. which help to define the radial distribution network easily and visually. After that, the search strategy for distribution connectivity analysis is presented. It processes a switch position change in a substation or on a feeder respectively, so as to improve the efficiency and speed of connectivity analysis. Finally, the functions of dynamic network coloring in DMS and their implementations are discussed.
