摘要
给出了基于故障电流补偿的配电网络短路计算网络图形模型,提出了“结点”图形模型概念。“结点”包含网络拓扑结构中所有的“节点”,是连接网络其他图形模型的交叉点。根据结点和其他图形元件的连接关系分析获得短路计算网络拓扑结构算法。该算法不仅能够准确地描述配电网络拓扑结构,还能生成短路计算所需的数据。在实际系统运行中表明,该算法具有一定的实用价值。
The graphic network models for power distribution short circuit calculation based on faultcurrent compensation are given. The 'crunode' model conception is proposed. 'Crunode' is the cross point connecting other graphic models,which includes all network nodes. According to the connective relationship between crunode and other graphic element,a network topology algorithm for short circuit calculation is obtained,which describes the distribution network topological structure exactly and generates the data necessary for short circuit calculation. The applications show its practical value.
