摘要

状态监测和性能诊断的变速交流驱动器今天是一种需要,或多或少,取决于他们的应用。诊断可以帮助避免意外停机,在发生故障时可以进行紧急操作,或者在发生故障时缩短维修时间。对于电压源型逆变器,可能存在几种故障。本文对这些故障及其诊断进行了介绍。列出了可能出现的故障和补救策略。列举了当今标准保护系统的故障诊断方法。主要的故障,通常不包括在这些系统中,是晶体管开路故障和直流母线电容故障。在这些领域,诊断方法正在研究中。这里概述了该领域研究小组的一些不同报告,作为对其功能和性质的调查。

Some diagnosis methods for voltage source inverters in variable speed drives with induction machines - a survey
Status monitoring and performance diagnosis for variable speed ac drives today is a need, more or less, depending on their application. Diagnosis can help to avoid unplanned standstill, to make possible to run an emergency operation in case of a fault or to keep the time to repair short in case of a fault. For the voltage source inverter several faults are possible. In this paper, these faults and their diagnosis are covered. Possible faults and remedial strategies are listed. It is enumerated, which faults in today's standard protection systems are diagnosed. The main faults, in general not covered in these systems, are the transistor open circuit fault and the dc bus capacitor fault. In these fields diagnosis methods are under research. Some of the various reports of research groups in this field are outlined here as a survey with respect to function and properties.
