Research and Development of an Improved Intelligent Operation Ticket System

With the development of power system informatization, the operation ticket expert system has been widely used in power system. This study designs the dynamic behavior reasoning mechanism of Petri net based on the knowledge base of operation ticket constructed by Petri net model. By modifying the operation rules of Petri net and introducing suppression arc, the reasoning process is simplified, the reasoning efficiency is improved, and the conflict resolution in the reasoning process is realized. The example shows that the system can manage the power grid structure hierarchically, solve the problem of “state combination explosion”, and improve the universality and adaptability of the whole operation ticket expert system.
