摘要：This paper presents a method of fault features extraction based on the stacked auto-encoder (SAE), and this method can be used to rotating rectifier diodes open-circuit fault detection of brushless ac synchronous generator. First, exciter generator field current is collected, and then processed by Fast Fourier Transform (FFT) to obtain the frequency components. Secondly, these components are deeply learned and evaluated by the stacked auto-encoder to extract features automatically. Finally, fault detection can be carried out with Euclidean distance calculation. The algorithm is validated based on a brushless ac synchronous generator test rig, and the experimental results show perfect fault detection performance under different load conditions.
