摘要：
The compensation capacitor fault of jointless track circuit has an important impact on the safe operation of high-speed trains. In order to solve the problem of multiple compensation capacitors breaking at the same time in jointless track circuit, a fault diagnosis method based on the amplitude characteristics of induced voltage envelope curve is proposed. Firstly, the shunt state model of track circuit is established, and the envelope curves of induced voltage amplitude corresponding to the disconnection fault of compensation capacitors at different positions are obtained by simulating analysis. Secondly, taking the distance between adjacent compensation capacitors as a step, the envelope curves of induced voltage amplitude corresponding to the faults of compensation capacitors at different positions are calculated, and the curves are segmented by according to the half step distance, and the eigenvalues of each segment are computed. Thirdly, the characteristic values of each segment are detected from the transmitter to the receiver to find the specific values, so as to realize the preliminary fault diagnosis of the compensation capacitor. Then, in order to make the fault diagnosis of compensation capacitor more accurate, according to the unique fault type, the slope is employed as the constraint condition for secondary diagnosis, so as to locate the fault capacitor position when multiple compensation capacitors break at the same time. Finally, by building a simulation platform and selecting the actual data of a road section, the proposed method is verified and compared. The results show that the algorithm can diagnose the position of the fault capacitor when multiple compensation capacitors on the track circuit break at the same time. The accuracy of the proposed algorithm is 99.04%, and it has high real-time performance. © 2022, Editura ELECTRA. All rights reserved.
