摘　　要：在智能电网调度防误操作拓扑分析过程中,当电网结构改变时,需要实时修正的内容会突然增加,严重影响分析效率,分析方法的工作效率需要进一步提高。针对该问题,提出基于故障树的智能电网调度防误操作拓扑分析。利用故障树技术中的各类符号描述不同的调度操作,在故障树中设定优先级,将调度操作的各项数据保存到故障树的叶节点中,并在各个节点之间建立起联系,根据优先级的高低处理不同的节点数据,完成对调度防误操作的诊断,同时利用电网的设备信息建立调度防误操作知识库,将其与诊断结果相结合,完成对智能电网调度防误操作的拓扑分析。实验结果表明提出的分析方法在不同操作环境下数据对接速度快、分析计算收敛速度高,整体工作效率得到了提升。In the process of topology analysis for anti-misoperation of smart grid dispatching,when the grid structure changes,the content that needs real-time correction suddenly increases,which seriously affects the analysis efficiency,and the work efficiency of the analysis method needs to be further improved.To solve this problem,a fault tree analysis based anti misoperation topology analysis for smart grid dispatching is proposed.Various symbols in fault tree analysis technology were used to describe different scheduling operations.Priorities were set in the fault tree,the data of scheduled operations was saved to the leaf nodes of the fault tree,and connections were established between the nodes.Different node data were processed according to the priority level,and the diagnosis of scheduling error prevention operation was completed.At the same time,the equipment information of the power grid was used to establish the knowledge base of dispatching anti-misoperation,and the topological analysis of the anti-misoperation of smart grid dispatching was completed by combining it with the diagnostic results.The experimental results showed that the proposed analysis method had fast data docking speed,high analysis and calculation convergence speed under different operating environments,and improved the overall work efficiency.
