An Innovative Approach of Control and Simulation Based Analysis of Doubly Fed Electrical Machines for Harnessing Wind Energy

摘要

Background/Objectives : Wind energy systems are need of the hour from electrical energy system point of view. Doubly fed electric machines are best suited for wind systems due to their ability to work under variable speed conditions. Methods/Statistical Analysis : This paper proposes a new configuration of doubly fed induction generator (DFIG) called as single external feeding of DFIG (SEF-DFIG) which has significant merits over the former system. Findings : The operating mode is presented with detailed analysis of the proposed system. Extensive simulation study is carried out by considering a hybrid energy system which consists of wind as well as other renewable energy sources. Application/Improvements : The results obtained during the simulation case study demonstrate the usefulness of the proposed system.
