Study on distilling fault character of converter based on genetic programming

The traction convertor is a key part to the whole system of the type CMS-3 maglev. Aming at the difficult problem of distilling the tractive fault character of the converter, the genetic programming method is adopted to distill the best fault character in this paper and the answers achieved by this method can effectively solve the problem. Compared with the method which uses the primitive fault characters to diagnose the traction converter, experiments show that the genetic programming method is proper, and it can find the best tractive fault character of the converter and distinguishably raise the diagnosing rate.
