摘　　要：随着城市电网的建设发展,其结构愈加复杂,而城市居民对于用电的要求也逐渐提高,在电网发生非瞬时故障时,需要迅速恢复无源区域供电,因此,能快速实现电网的拓扑分析并生成转供电方案十分重要。文中提出了一种基于图数据库算法和模式匹配自动生成转供电方案的方法,将电网结构以图的形式存储于图数据库中,并将转供电方案生成过程中需要的主接线特征预先从图数据库中采用双向广度优先算法进行提取。在实际故障发生时,根据告警信息和电网状态进行有源性分析,运用生成的主接线模式查询能作为失压设备源节点的设备及对应的恢复供电路径,结合路径上各设备实际状态,得到相应的动作开关,并基于操作的快捷性和系统的安全性建立转供电方案评价体系,确定最佳转供电方案。With the development of the urban power grid,its structure is becoming more and more complex,and the requirements of urban residents for power consumption are gradually improved.When permanent fault occurs in the power grid,it is necessary to restore passive area power quickly.Therefore,it is very important to realize the grid topology analysis and generate the power transfer scheme as soon as possible.In this paper,a method for automatically generating a power transfer scheme based on graph database algorithms and pattern matching is proposed.The grid structure is stored in the graph database in the form of graph,and the main wiring characteristics that may be used in the process of generating the power transfer scheme are extracted from the graph database by double breadth first search algorithm.When an actual fault occurs,the active analysis is carried out according to the alarm information and the grid diagram.Query the equipment that can be the source node of the voltage-loss equipment and the corresponding restore power supply path based on the generated main wiring mode,and generate corresponding switch operations with the actual status of the equipment on the path.An evaluation system for the power transfer scheme based on the quickness of operation and the safety of the system is established to determine the best transfer power supply scheme.
