Application of Hybrid Algorithm Based on GA-BP in Transformer Diagnosis Using GAS Chromatographic Method

In this paper, a hybrid algorithm which combines improved genetic manipulation with artificial network is applied to fault diagnosis of power transformer. It overcomes the .shortcomings of entrapment in local optimum, slow convergence of ordinary BP algorithm and the premature convergence of basic GA effectively. Simulation diagnosis results of practical examples show that the convergence rate of the proposed method is faster and the computational result is more accurate than others, the proposed method fulfils the requirements of fault diagnosis of power transformer.
