摘　　要：系统拓扑结构分析是电力系统运行、分析与控制的基础工作,发电厂、变电站为电力系统拓扑网络的节点,而且其主接线最为复杂。通过对各种主接线形式的拓扑关系分析,提出电力系统主接线的状态描述方法,该方法不仅能够用解析方法描述设备间和间隔间的网络拓扑关系,而且可以利用信号流图方法求解支路的导通状态,并给出解析形式的支路联通增益。Network topology analysis is one of bases for power systems operating,analyzing and controlling.Power plants and substations are nodes of power systems network topology,and they are the most complex connections.In this paper,a statement space method of main electrical connection is described.Not only the network topology structure of main electrical connection but also the conduction states of switch devices are represented by this method,and the analytic solution of the branch switch logical gain between any two nodes is given.

关 键 词：状态模型 网络拓扑 信号流图
