Abstract

In order to address problems in incipient fault detection of traction system for high⁃speed trains, firstly, data collected from the system was processed by GAE. Then, statistics were tested on residual generator carrying fault information, which could effectively enhance fault detection ability. Finally, effectiveness and feasibility of the proposed method were validated on a traction system platform of high⁃speed trains, where four kinds of faults were studied, including air gap eccentricity, bar breaking, end link and bearing. The results show that the residual generator of GAE has strong applicability and sensitivity, and can adapt to the nonlinear characteristics of traction system. There is no false alarm phenomenon in fault detection, and the missing alarm ratio is less than 6%. © PHYSOR 2022 China Safety Science Journal. All rights reserved.
