Reliability Analysis of Fault Tolerant Wind Energy Conversion System with Doubly Fed Induction Generator

Abstract

Abstract. This paper deals with the design of a reliable fault tolerant converter topology for grid connected Wind Energy Conversion System (WECS) with Double Fed Induction Generator (DFIG) based on functional redundancy. The main contribution of the developed topology consists to achieve a reconfiguration mechanism based on the functional compensation principle in the presence of components failures. Various reliability analyses based on Markov chain model are developed to determine the effectiveness of this fault tolerant control topology against failures. Application results are presented on a WECS simulator.
