摘要
通过分析配电网的有向拓扑图，建立了配电网的数学模型——节点线段关联矩阵，并在该数学模型的基础上，分析归纳出节点阻抗矩阵各元素的计算方法。结合配电网的特点，提出了一种简单、准确的配电网短路计算机算法。
Through analyzing the directed topological graph, a mathematical model of distribution system, i.e., the correlation matrix of nodes and line segments, is built. On the basis of this model the calculation method for each element in node impedance matrix is derived, and a simple and accurate algorithm of distribution network short circuit fault is put forward.
