摘　　要：智能操作票系统在实际应用时需要提前配置大量的规则模板,存在工作量庞大且易出错的问题。采用图论思想对智能操作票系统进行模块化分析,构建电网拓扑数学模型完成规则推理,实现电网拓扑结构存储及数学矩阵分析。在改进原系统的基础上设计了一种针对不同级别事故的误操作告警系统,在操作票导出前对操作指令进行电网系统仿真,判断仿真运行电网稳定性,判定导出操作票是否为误操作。基于模糊评判方法对操作人员在长期工作中的操作可靠性进行评估,进行告警与数据查询。算例验证结果表明,该系统能有效预防人为操作失误,减少风险发生概率。The intelligent operation ticket system requires a large number of rule templates to be configured in advance,which can result in a significant workload and potential errors during configuration.The idea of graph theory is used to conduct modular analysis of the system,construct a mathematical model of the power grid topology to complete rule reasoning,and realize storage of the power grid topology structure and mathematical matrix analysis.Based on an improved version of the original system,a misoperation alarm system is designed.Before an operation ticket is exported,the power grid system is simulated for the operation instructions,the stability of the simulated power grid is judged,and it is determined whether the exported operation ticket is a misoperation.Finally,the fuzzy evaluation method is used to evaluate the operational reliability of operators in long-term work,and an early warning system for different levels of accidents is designed to provide alarm and data query.The numerical example verification results show that the system can effectively prevent human operating errors and reduce the probability of risk occurrence.
