Abstract
In order to improve the fault diagnosis accuracy of on load tap changer(OLTC)for transformers,it proposes an OLTC fault diagnosis method.Firstly,it extracts six feature quantities of OLTC operating stateusing variational mode decomposition(VMD)method.Secondly,with the six features as input and OLTC fault type as output,it uses the golden jackal optimization(GJO)algorithmto optimize the network parameters of deep belief networks(DBN).Finally,it constructs a GJO-DBN model and carries out the fault diagnosis of OLTC using the GJO-DBN model.The case analysis results show that the diagnostic accuracy of the GJO-DBN model is as high as 98.88%,and the average computation time is only 12.33 s.This model can not only improve the fault diagnosis accuracy of OLTC,but also shorten the calculation time,verifying the effectiveness of the proposed OLTC fault diagnosis method.关键词
