基于馈线区间和GIS的配电网网损计算拓扑分析方法

结合配电自动化的工程实际问题 ,提出将馈线区间作为一个图 ,并将区间内各节点作为图的顶点 ,节点间线段作为图的弧 ,以线路潮流的方向作为弧的方向 ,并由此建立了配电网馈线区间的数学模型。在该模型的基础上定义了区间的网基结构矩阵和有向描述矩阵 ,并将其进一步结构化。从而得到能与GIS平台拓扑分析功能紧密结合的数据结构和计算分析方法。最后 ,描述了基于该方法的网损计算过程 ,并讨论了对不完整量测数据的处理问题。

Topology analysis method for loss calculation of distribution network based on feeder sections and GIS

Combined with engineering practices, this article proposes that feeder section is regarded as graph, the nodes inside the section are treated as vertexes of graph, and the lines between nodes as arcs. Their directions are load flow's directions in the lines, and the model of feeder section in distribution network is constructed. Based on this model, network-base structure matrix and directional describing matrix are defined, and deeply, they are structured. Therefore, we get the data structure and methodology which are combined with the topology function of GIS closely. Finally, the procedure of calculation based on this method is described, and the problem of incomplete measured datas is discussed.
