| Abstract: | Power transformer partial discharge location with ultrasonic is discussed in this paper.A mathematical model for ultrasonic localization is developed and simplified to a nonlinearly continuous function optimization problem.Particle swarm optimization（PSO） algorithm with Chaos Search is proposed to solve the problem.The results of calculating examples show that the algorithm can effectively prevent finding local extremes,and it can find the partial discharge source quickly and accurately. |
