Renewable energy based experimental study of doubly fed induction generator: Fault case analysis

Abstract

Environmental-friendly technologies, such as wind power based generators having much attention, and the study of these generator's behaviour under fault conditions and to overcome these undesirables during operation have become an essential topic. In this article, the simulation and experimental analysis of Double-fed induction generators (DFIG) dependent wind type are discussed and introduced to these unwanted conditions. The simulation and experimental outcome show that the decline of parameters, i.e. transient time, maximum current and voltage drop at the common coupling point (PCC) and grid side converter (GSC) of DFIG, occurs after an unwanted short-circuit. Exciting simulation and theoretical outcomes represented a sensitive and robust point under DFIG's symmetric short-circuit (SSC). Present results report a significant variance between GSC and PCC points under SSC fault disorder. The fault point performance study is expected to identify and measure the comparative of sensors sensibility for protection strategies. It also will be geared to develop renewable energybased advanced control schemes and the selection of an effective system.
