Abstract: Introduction was made to the basic principle and algorithm steps of genetic algorithm. This paper rebuilt its coding and decoding plans, restricting conditions’ treatment, searching speed and global optimization etc., so as to enable new mass body’s quality better and to quicken the optimization process. The improved genetic algorithm was adopted to carry out optimization for electromagnetic calculation design of dry type power transformer, applied in the single goal and dual goal optimization design for SGB-800/10 dry type power transformer. The actual example parameters comparison and analysis show that the algorithm is actually feasible with better optimization effect.
       Key words: dry type transformer; improved genetic algorithm; optimization design
