A kind of distribution automation switch fault diagnosis method, equipment and readable storage medium

Abstract

The invention discloses a fault diagnosis method, equipment and readable storage medium for a power distribution automation switch. Index system; Step 2, establish the fuzzy evaluation model factor set and stratification, judge the membership function of the factors, and finally establish a distribution automation switch state evaluation model based on the hierarchical fuzzy comprehensive evaluation; Step 3, according to the improved gray correlation of fuzzy C-means Using the degree method, a fault diagnosis model of distribution automation switches based on fuzzy C-means clustering was established. The invention uses the fuzzy C-means clustering method to cluster the reference sequence to select the most representative sequence, the improved analysis method improves the calculation efficiency, and achieves the purpose of using the system information to complete efficient fault diagnosis; By distinguishing the results, it is not easy to produce biased judgment errors, which improves the accuracy and efficiency of fault identification.

Description

【Technical field】 [0001] The invention belongs to the field of power distribution automation switch fault diagnosis, and relates to a power distribution automatic switch fault diagnosis method, equipment and readable storage medium. 【Background technique】 [0002] With the continuous development of economy and society, the whole society has put forward higher requirements for the reliability of power supply. As a terminal system that has a direct relationship with users, the distribution network reflects the requirements of users in terms of safety and economy in real time, and its safety and stability are very important. The improvement of the reliability of the power supply of the distribution network is inseparable from the highly reliable distribution automation switchgear. Improving the reliability of distribution automation switches is an inevitable requirement to improve the stability of the power supply of the distribution network. [0003] In order to improve the ...

Problems solved by technology

There are literatures that use the sampling method to evaluate the switchgear as a whole, and use online monitoring data for individual evaluation, but it only starts from the individual switchgear and lacks the consideration of the overall operation of the power grid; Quantify the information of electric switchgear and obtain its overall state evaluation results, but it does not carry out weight analysis on the layered part, and only completes the state evaluation; there are also literatures that propose a layered fuzzy comprehensive evaluation combined with entropy weight theory solution, but it does not consider the cause of the fault, and cannot be used as a reference for fault diagnosis
