Synchronous generator based wind energy conversion system feeding isolated load using vft

This paper aims to explore the possibility of synchronous generator (SG) based wind energy generation system feeding an isolated load using a power transmission technology i.e. variable frequency transformer (VFT). The configuration proposed in this paper does not employ any power electronics based interface as in conventional SG based stand-alone wind energy conversion systems (SWECS). The simulation models of proposed as well as conventional configuration have been developed using MATLAB for analysis. Further to analyze the effectiveness of the proposed method; the efficiency, total harmonic distortion (THD) of output voltage and THD of output current of the proposed method have been compared with those of the conventional method. From obtained results, it is observed that the proposed method is simple and does not produce harmonics. From the cost analysis, it is observed that the proposed system is cheaper than the conventional system.
