Analysis on the ultrasonic online location for partial discharge in the stator winding of generator
摘要
Abstract
The propagation characteristics of the partial discharge's ultrasonic signal in the stator of generator and the difference between the ultrasonic signal and the running background noise are analyzed with experiments. Ultrasonic online location for partial discharge is proven to be feasible. For non-blind area monitoring, the stator is divided into several equal parts. Locating equations are established with electroacoustic detection method and optimized with genetic algorithm. The simulation results indicate that the proposed method of ultrasonic online location for the partial discharge in the stator of generator is correct.关键词
