配电网的模型化方法

Approach to Modeling Distribution System

提出将配电网的馈线开关当作图的顶点 ,将配电网的馈线当作图中的弧的配电网数据模型化方法 .定义了网基结构矩阵、弧结构矩阵和负荷矩阵等数据结构以及基形变换、点弧变换和弧点变换等数学变换 .在建立的模型基础上 ,提出了判断和隔离故障区域的过热弧搜寻法 ,讨论了配电网负荷均衡化。

A new model of distribution system is presented,whereby the feeder switches are regarded as the vertexes of a graph and the feeder lines are regarded as the arcs. Several data structures are defined to describe the distribution system such as net base matrix, arc matrix and load matrix, etc. Based on the proposed data structure, the transforms of base to shape,vertex to arc, and arc to vertex are discussed together with the process of detection and isolation of fault sections,load balancing, optimum restoration and dispatching simulation.
