英文摘要：

The principle of ultrasonic localization method of partial discharge in power transformer is ex- pounded and the hybrid genetic algorithm is applied to the ultrasonic localization, so that an ultrasonic lo- calization method of partial discharge in power transformer is presented based on hybrid genetic algorithm. The result of its localization is compared with that of other localization methods such as genetic algorithm, simulated annealing algorithm, particle swarm optimization （PSO） algorithm, and linear particle swarm optimization algorithm. It is shown by the results of calculation example that the hybrid genetic algorithm can effectively prevent the localization from being caught in local optimal, making the effectiveness of lo- calization with hybrid genetic algorithm ideal and better than all other intelligent algorithms mentioned a- bove.
