Detection and Diagnosis Solutions for Fault-Tolerant VSI

Fault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault

In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...

Diagnosis and Fault - Tolerant

Overview of Fault Detection Security and reliability are of great importance in control system technology. To ensure a reasonable level of security and reliability, the need for failure detection (diagnosis) techniques has long been recognized. Roughly speaking, a failure is any kind of malfunction of the system that leads to unacceptable performance. Failure detection consists of techniques fo...

Sensor Fault Diagnosis of Wind Turbines for Fault Tolerant

This paper aims at the blade root moment sensor fault detection and isolation issue. The underlying problem is crucial to the successful application of the individual pitch control system which plays a key role for reducing the blade loads of large offshore wind turbines. In this paper, a wind turbine model is built based on the closed loop identification technique, where the wind dynamics is i...
