摘要
旋转整流器是同步交流发电机的核心部件,容易发生故障。通过仿真分析,验证基于小波变换的同步交流发电机旋转整流器故障诊断方法。仿真实验结果表明该方法不仅能够有效判别是否发生故障,同时能够判别故障类型,诊断正确率高,基于小波变换的诊断方法可用于同步交流发电机旋转整流器故障模式的快速诊断。
The rotating rectifier is the core component in the synchronous AC generator.But it is easy to fail.The fault diagnosis of the rototing rectifier of the synchronous AC generator based on Wavelet Transform is verified.The results in experiments show that the fault diagnosis method can be used to effectively detect fault and classify failure modes.The proposed method is of high accuracy and it can be used for the rapid fault diagnosis of the rotating rectifier.
