基于矢量坐标搜索法的地区电网网络拓扑方法的研究

提出了一种面向对象的抽象电力网络拓扑的模型，并用此模型实现了用系统矢量图的坐标关系自动生成原始拓扑的方法。该方法是根据设备图元对象的端点坐标位置自动搜索确定的原始拓扑关系，即设备图元的连接关系，基于连接规则和节点融合的快速拓扑分析算法，根据原始拓扑关系确定各支路与母线的连接情况，该方法可用于电网动态着色和状态估计，潮流调度，安全分析，无功优化等网络分析程序之中。

Research of a network topology method based on vector coordinates

An abstract object-oriented model for power network topology is built up and an automatic generation method of primary topology is introduced,which applies the model and system vector coordinates.The primary topology is determined by automatic searching according to the end coordinates of device elements,i.e.the connection relationships.With fast topology analysis algorithm based on connection rules and node merging,the connection conditions of branches and buses are determined according to the primary topology.The method can be applied to power system analysis software,such as dynamic coloring,state estimation,power flow and so on.
