An online fault diagnosis method for high-voltage switchgear based on multi-agent collaboration

Abstract

The invention provides an online fault diagnosis method for a high-voltage switchgear based on multi-Agent cooperation. Including: S1. Use the Apriori algorithm to calculate the correlation coefficient between the failure factors and failure rates of the high-voltage switchgear, and establish a panoramic model of the high-voltage switchgear state; S2. According to the international, national and industry standards of the IEC 61968 / 61970 power industry, access The data of each application system is associated with information and multi-dimensionally processed to form a data frame; S3, through the redundancy and complementarity of the high-voltage switchgear state fault diagnosis and analysis method through the data frame, construct a multi-Agent collaborative diagnosis model; S4, through the The information fusion agent determines the importance weight of each index on the agent hierarchical structure diagram, calculates the relative weight of the diagnosis results of each agent at the scheme layer, and fuses the results with differences and redundancy of each diagnosis agent to obtain the online accident details. The method of the invention has high efficiency, and the overhaul of the repairing equipment is timely.

Description

technical field [0001] The invention relates to the technical field of online fault diagnosis of high-voltage switch cabinets, in particular to an online fault diagnosis method for high-voltage switch cabinets based on multi-Agent collaboration. Background technique [0002] The high-voltage switchgear is a very critical equipment in the distribution network system. It bears the heavy responsibility of putting some power lines into operation or cutting out. It is related to the operation level, safety degree and power supply service quality of the distribution network. Once the high-voltage switchgear occurs Faults will first cause damage to related power equipment and lines, and then cause large-scale power outages and other power supply accidents that affect the normal production and life of the people. [0003] For high-voltage switchgear and other important electrical equipment, at present, the distribution network equipment is generally overhauled regularly, which can e...

AI Technical Summary

Problems solved by technology

[0012] The above method of periodic inspection or diagnosis by inspectors is relatively simple, and since most of the current online diagnosis systems are single systems, the diagnostic ability of the above method of periodic inspection or diagnosis by inspectors is relatively weak on the whole. The diagnosis effect of the switchgear fault is not good
