Abstract

The invention discloses an improved fuzzy Petri field fault diagnosis method for electric power communication, which comprises the following steps: an improved dynamic fuzzy petri net algorithm is defined; based on the algorithm, a dynamic fuzzy petri net model for fault diagnosis in electric power communication field is constructed; and the constructed dynamic fuzzy petri net model is applied tothe fault diagnosis of electric power communication field. Based on the fuzzy Petri net theory, the present invention proposes a dynamic electric power communication network field fault diagnosis method, effectively avoids the error caused by artificial subjective factors in the fault diagnosis process of the fuzzy Petri net, and improves the accuracy of the reasoning process.

Description

technical field [0001] The invention relates to the technical field of electric power communication field fault diagnosis, in particular to an improved fuzzy Petri electric power communication field fault diagnosis method. Background technique [0002] In recent years, the scale of power communication network has grown rapidly, effectively improving the safety level of power grid dispatching and control, enterprise production and operation management, and ensuring the reliability of various information transmissions in power systems in harsh climate environments. But at the same time, the degree of coupling between communication networks is getting closer and closer, and the complexity of the grid topology is also rising sharply, which has brought adverse effects on on-site operation and maintenance and troubleshooting. With the rapid development of computer technology and automation technology, professional network management systems, intelligent devices, sensors and other ...
