从而验证了该方法的有效性。

Abstract

In order to overcome the influence of the fault diagnosis results of the transformer fault sample data

in this paper

based on rough set

a new method of fault diagnosis for the fault diagnosis method of artificial fish swarm is constructed

in this method

the rough set is used to reduce the 16 conditional attributes in the decision table;Secondly

according to the most simple rule table

the training sample is encoding

and the training sample of encoding is used to train the extreme learning machine.The weight and the threshold value of the extreme learning machine are optimized by artificial fish swarm optimization method;Finally

using the method of the training of good limit learning machine to the good sample of encoding fault diagnosis.This method can improve the accuracy of fault diagnosis by combining rough sets with the excellent characteristics of the incomplete data and the good generalization ability of the extreme learning machine.The comparison analysis of the case shows that the method proposed in this paper has higher diagnostic accuracy

and the validity of this method is verified.
