Abstract: With the global search performance of genetic algorithm and the local search capability of back propagation (BP) algorithm, this paper raised a kind of fast convergence improved genetic mixed algorithm, which was applied in power transformer fault diagnosis to analyze gases dissolved in the oil. The actual result shows that the algorithm can classify effectively for each kind of fault in power transformer, with faster convergence speed and higher diagnosis accuracy.
Key words: power transformer; genetic algorithm; artificial neural network; fault diagnose
