配电网关联矩阵的生成及其应用

The Generation and Application of Incidence Matrix in Power Distribution System

在高压配电网的矩阵算法中,利用线段与结点的关联矩阵描述了配网的拓朴性质.但是由于高压配电网具有多支线多结点的特征,因而使关联矩阵的维数较高(当配网结点为100个,则关联矩阵为100×100的二维矩阵).当将点作为配网原始数据存入配网参数数据库,必将占有较大的存贮容量.为此,本文提出了一种简单的配网关联矩阵的自生成方法,当对配网运行参数进行计算时,可利用本文方法先在计算机中生成关联矩阵,再进行所需运行参数的计算。由于不需要把关联矩阵存入配网参数数据库,因而使数据库所占用的存贮客量大大减少.

In the matrix method of computing a high voltage power distribution system, the incidence matrix is used to describe the topology properties of the electrical networks. Because of a lot of branches and nods in the distribution system, the dimensions of incidence matrix are generally very large.(With the number of nods being 100, the incidence matrix will be two dimensional matrix of 100 x 100.) It will occvpy a large space in the data base of the distribution system. This paper provides a simple method to generate the incidence matrix by itself. There—fore, in the process of analysing a distribution system by computer, it's not necessary to store the incidence matrix in the data base of the distribution system, so it occupies a smaller memory space.
