【摘要】 提出了一种配电网简化模型 :将配电网的馈线开关当作节点 ,将馈线当作弧。定义了描述配电网潜在连接关系的网基结构矩阵和描述配电网当前连接关系的弧结构矩阵 ,并讨论了根据配电网潜在连接关系和馈线开关的位置推算出配电网当前连接关系的方法。定义了负荷矩阵 ,并讨论了根据节点负荷推算出馈线供出负荷的方法及根据馈线供出负荷推算出节点负荷的方法。基于这些新模型 ,发展了故障区域判断、健全区域优化恢复供电、配电负荷均衡化及配电网调度仿真的方法 ,即使在严重缺乏量测数据的情况下 ,也实现了配电自动化高级应用功能更多还原

【Abstract】 A new approach to modeling distribution system is presented, i.e., the feeder switches are regarded as the vertexes of a graph and the feeder lines are regarded as the arcs. Several data structures are defined to describe the distribution system, such as net base matrix, arc matrix and load matrix, etc. The transforms of base to shape, vertex to arc and arc to vertex are dealed with. Based on the new model, the method to detect and isolate the fault section is discussed together with the process of load balancing, optimum restoration and dispatching simulation.Advanced functions are feasible even in the case of being lacking in necessary data.更多还原
