摘要

本文提出了一种用于变速发电的双馈感应电机(DFIM)早期电气故障检测的诊断技术。在这种应用中，定子绕组直接连接到电网，而通过磁场定向控制(FOC)方案控制转子电流的转换器为转子供电。本文的目的是介绍一种基于转子逆变器输出电压分析的新型诊断技术。特别是，它将表明，这些信号的频率分析导致一个有效的诊断程序。所提出的系统适合于插入任何现有的foco - dfim驱动系统。

A General Diagnostic Method for Doubly Fed Induction Machine Drives Based on Field Oriented Control

This paper presents a diagnostic technique for the detection of incipient electrical faults in a doubly fed induction machine (DFIM) used for variable speed generation. In this application the stator windings are directly connected to the grid, whereas a converter, which controls the rotor currents by means of a field oriented control (FOC) scheme, supplies the rotor. The aim of this paper is to introduce a new diagnostic technique based on the analysis of the rotor inverter output voltages. In particular it will be shown that the frequency analysis of these signals leads to an effective diagnostic procedure. The presented system is suitable to be easily plugged in any existing FOC-DFIM drive system.
