“…Faults related to winding insulation comprise between 21% and 40% of total failures in electrical machines [27], [28] depending on the type and size of the machine. A comprehensive review of CM and fault detection regarding winding insulation can be found in [28], [29]. Winding faults are usually the final result of the slow and continuous aging of the windings insulation.…”

“…Finally, the slot insulation or insulation of another phase can be affected, leading to a catastrophic phase-ground or phase-phase failure. This process develops rather quickly [29]. If appropriate measures are not taken within a few seconds, the localized failure can evolve to catastrophic failure [28].…”

“…Many solutions have been proposed in the literature to detect and compensate ITSC fault. Isolation testing technique based on the partial discharge analysis was proposed in [11] as a solution for detecting ITSC. Jeong et al [12] proposed the negative sequence currents analysis approach for diagnosing ITSC faults.…”

Short-Circuit Fault Tolerant Control of a Wind Turbine Driven Induction Generator Based on Sliding Mode Observers

et al. 2017

Abstract:The installed energy production capacity of wind turbines is growing intensely on a global scale, making the reliability of wind turbine subsystems of greater significance. However, many faults like Inter-Turn Short-Circuit (ITSC) may affect the turbine generator and quickly lead to a decline in supplied power quality. In this framework, this paper proposes a Sliding Mode Observer (SMO)-based Fault Tolerant Control (FTC) scheme for Induction Generator (IG)-based variable-speed grid-connected wind turbines. First, the dynamic models of the wind turbine subsystems were developed. The control schemes were elaborated based on the Maximum Power Point Tracking (MPPT) method and Indirect Rotor Flux Oriented Control (IRFOC) method. The grid control was also established by regulating the active and reactive powers. The performance of the wind turbine system and the stability of injected power to the grid were hence analyzed under both healthy and faulty conditions. The robust developed SMO-based Fault Detection and Isolation (FDI) scheme was proved to be fast and efficient for ITSC detection and localization.Afterwards, SMO were involved in scheming the FTC technique. Accordingly, simulation results assert the efficacy of the proposed ITSC FTC method for variable-speed wind turbines with faulty IG in protecting the subsystems from damage and ensuring continuous connection of the wind turbine to the grid during ITSC faults, hence maintaining power quality.

This article is intended as an introduction to the field of induction machine fault diagnosis. Its objective is to give an overview of the problems that arise in this field and the methodologies used to solve them, so that readers are given access to the abundant available technical literature. In the first part of the article, basic concepts and terminology used in this field are introduced. A classification of the different types of faults is made, and the concepts of on‐line, off‐line, stationary or transitory diagnosis, and diagnostic methodologies in the time domain, frequency domain, or the time–frequency domain are explained. The most widely used mathematical tools are also introduced in a conceptual way and are related to the previous concepts. In the second part of the article, a section is dedicated to each of the main types of faults. In each case, the causes of the fault, the consequences, and the physical phenomena they produce are explained. These physical phenomena are the basis of the fault diagnosis techniques, which are explained below. For each type of fault, the most widely used methodologies in the industrial field are presented, and in some cases alternative methods proposed in the literature, aimed at solving specific problems, are also commented. Throughout the article numerous examples based on laboratory tests and measurements obtained under real operating conditions are presented, which facilitate the understanding of the concepts being explained.
