Fault Diagnosis of Power Transformer Based on DGA of Algorithm for SVM
In response to parameter selection seriously affect classification results in SVM
this paper proposes a method using differential evolution optimizes on parameter of kernel function g and penalty parameter c
aiming to getting the SVM machine model for the fault diagnosis of transformer. Firstly
this paper analyzes the feasibility of using differential evolution algorithm for SVM optimization based on the brief introduction of SVM. Through pretreating the collecting data samples and using the mutation
crossover and selection of differential evolution optimizes on RBF
the best parameters c and g are found out
and the parameters to obtain the SVM model are verified. The results show that
compared with non-optimized SVM
GRID-SVM
GA-SVM and PSO-SVM
this method has the lowest misjudgment rate and good global search ability and better robustness.
