Abstract: 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.
