Abstract

Transformer is the core equipment of power grid

winding deformation is one of transformer common faults

and frequency response analysis is a widely used winding deformation detection method.In order to improve the performance of classifying and diagnosing winding deformation

this paper proposes a transformer winding deformation classification method based on particle swarm algorithm optimizing support vector machine

the mathematical statistical method is used to extract the characteristic parameters of frequency response curves

which are imported into SVM model to perform the training.The particle swarm algorithm is used to optimize the parameters of SVM model

to effectively distinguish variable winding fault types.In order to prove the effectiveness of the presented method in diagnosing transformer winding faults

a series of fault emulating experiments are carried out on a specially manufactured model transformer.The data process result indicates that the SVM model after training presents high performance;moreover

compared to the traditional grid searching parameter optimization method

the SVM which is optimized by particle swarm algorithm can remarkably improve the performance of classifying transformer winding deformation faults.
