Research and Application Analysis on the Real-time Axle Temperature Monitoring and Diagnosis Logic of High-speed Multiple Units

Autor: HUANG Di, LI Zixian, HOU Zhaowen, LIU Can, LIN Bo, ZANG Xiaobin

Publikováno v: Kongzhi Yu Xinxi Jishu, Iss 3, Pp 109-114 (2024)

The conventional diagnostic logics for hotbox warning/alarms are mainly based on predefined absolute temperature thresholds and temperature rising slope thresholds. They often fall short in effective analysis and judgments when encountering fluctuati

Diagnosis of broken rotor bar fault in open‐ and closed‐loop controlled wye‐connected induction motors using zero‐sequence voltage

Autor: Ming Ye, Hou Zhaowen, Jin Huang, Liu Zijian, Jiaqiang Yang, He Liu

Publikováno v: IET Electric Power Applications. 11:1214-1223

This study proposes a method to detect and quantify broken rotor bar fault using zero-sequence voltage in a wye-connected squirrel-cage induction motor. The zero-sequence voltage is analysed and two fault severity factors are defined. The factors are

No‐load losses based method to detect demagnetisation fault in permanent magnet synchronous motors with parallel branches

Autor: Jin Huang, He Liu, Ming Ye, Hou Zhaowen, Jiaqiang Yang, Liu Zijian

Publikováno v: IET Electric Power Applications. 11:471-477

For permanent magnet synchronous motors with parallel branches, circulating currents are induced by a partial demagnetisation fault. The induced currents increase the losses of the motor. Therefore, detecting such a fault becomes possible by analysin

Stator inter‐turn fault detection in closed‐loop controlled drive based on switching sideband harmonics in CMV

Autor: He Liu, Jiaqiang Yang, Ming Ye, Hou Zhaowen, Jin Huang

Publikováno v: IET Electric Power Applications. 11:178-186

This study proposes a method for stator fault detection of inverter-fed induction machine in closed-loop control. The sideband response of inverter switching harmonics in common-mode voltage (CMV) is employed to detect the stator inter-turn fault, th

Fault Detection of Accelerometer and Fault-Tolerant Control for Maglev

Autor: Guo Wei, Chen Ke, Hou Zhaowen, Wang Wentao, Xu Shaolong, Chen Qihui, Gan Weiwei

Publikováno v: 2019 IEEE Vehicle Power and Propulsion Conference (VPPC).

Electrical magnetic suspension system is widely used in medium-low and high speed maglev vehicles. The system is an unstable and nonlinear complex system. Accelerometers are widely used in the system to obtain acceleration information for electromagn

Quantitative broken rotor bar fault detection for closed‐loop controlled induction motors

Autor: Zhao Lihang, He Liu, Jin Huang, Hou Zhaowen, Wang Tong

Publikováno v: IET Electric Power Applications. 10:403-410

In an induction motor with broken rotor bars, stator currents contain fault-related components. The fault information propagates to voltages when the motor is in a closed-loop control. The control has an effect on the currents and voltages. Relying s

Inter-turn fault detection for the inverter-fed induction motor based on the Teager-Kaiser energy operation of switching voltage harmonics

Autor: He Liu, Jin Huang, Hou Zhaowen, Yan Sun, Wang Tong

Publikováno v: 2015 18th International Conference on Electrical Machines and Systems (ICEMS).

This paper presents a stator inter-turn fault detection approach for the inverter-fed induction motor (IM) based on the Teager-Kaiser energy operation (TKEO). The zero sequence voltage under the excitation of the inverter switching harmonics is analy

A current product signal analysis method for rotor fault diagnosis in induction motors

Autor: He Liu, Zhao Lihang, Hou Zhaowen, Wang Tong, Jin Huang

Publikováno v: 2015 IEEE 10th International Symposium on Diagnostics for Electrical Machines, Power Electronics and Drives (SDEMPED).

This paper proposes a new current based diagnosis method, which is the so called current product signal analysis method (CPSA), for rotor fault diagnosis in induction motors. The major theoretical principles of CPSA are presented in this paper and it
