High-voltage circuit interrupter fault diagnosis method based on grey correlation fuzzy clustering

Abstract

The invention discloses a high-voltage circuit interrupter fault diagnosis method based on grey correlation fuzzy clustering. A fuzzy similarity relation matrix is gained by means of a correlation coefficient method, and then a transitive closure operation is conducted. On the basis, clustering analysis is conducted, so that a class which a fault to be diagnosed is in can be gained. By searching for a fault which is similar to the fault to be diagnosed in the class, the component which produces the fault can be gained. The grey correlation analysis method is a powerful tool for resolving a fault diagnosis with little data and weak conditions, and has the advantages of being simple in modeling, little in needed data, and capable of gaining an accurate fault diagnosis under the condition that a confidence level is not very good, thereby providing a basis for reasonable recondition arrangement and safe operation. Large amount of human resource is saved and unnecessary waste is reduced. By adopting the high-voltage circuit interrupter fault diagnosis method based on grey correlation fuzzy clustering in the fault diagnosis of a high-voltage circuit interrupter, the work volume is reduced greatly. The high-voltage circuit interrupter fault diagnosis method based on grey correlation fuzzy clustering has a good application prospect.

Description

technical field [0001] The invention relates to a high-voltage circuit breaker fault diagnosis method based on gray relational fuzzy clustering, and belongs to the technical field of high-voltage circuit breaker fault diagnosis. Background technique [0002] With the rapid development of the economy, the form of power supply in my country is becoming increasingly tense, and the economic losses caused by the failure of the power grid system in all parts of the country are as high as trillions. The main reason for the analysis is that the failure of the power grid system cannot be dealt with in time. We It is known that the high-voltage circuit breaker plays a key role in protecting the power grid system. The high-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, but also pass through when the power grid system fails. The role of the connected relay protection device is to cut off the ...

Problems solved by technology

At present, although enough attention has been paid to the fault diagnosis of high-voltage circuit breakers, the progress is slow, and the optimal method for fault diagnosis of high-voltage circuit breakers has not been explored. The fault analysis at this stage is cumbersome and complicated, and the fault of high-voltage circuit breakers cannot be quickly given diagnosis in order to deal with the fault in time, affecting the normal power supply and causing economic losses
