摘要

本文提出了一种利用谐波分量对双三相永磁同步电机(pmms)进行快速有效的开相故障(OPF)诊断方法。诊断包括故障检测和定位两部分,其中基于四次谐波的指标用于检测OPF是否发生,基于二次谐波的指标用于定位OPF。这种两步故障诊断方法可以在1/5个电气周期内定位故障,速度快,计算效率高。此外,它不依赖于电机参数,对运行条件的变化具有鲁棒性。与现有方法相比,该方法适用于各种控制策略的表面安装和内部电机。实验和比较验证了所提方法的性能。

A Fast and Efficient Two-Step Open Phase Fault Diagnostic Method for Dual Three-Phase PMSMs Using Harmonic Components
This letter proposes a fast and efficient open phase fault (OPF) diagnostic method using the harmonic components for dual three-phase permanent magnet synchronous machines (PMSMs). The diagnosis consists of fault detection and localization, in which the indicator based on fourth harmonic is derived to detect whether OPF happens, and the indicator based on second harmonic is derived to locate the OPF. This two-step fault diagnostic method can locate the fault within 1/5 electrical cycle, which is fast and computation-efficient. Moreover, it does not depend on motor parameters and is robust to operating condition change. Compared with existing methods, the proposed method is applicable to both surface-mounted and interior motors with various control strategies. Experiments and comparisons are conducted to validate the performance of the proposed method.

期刊介绍: The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
