Novel Power Coefficient for extracting the maximum power in Wind power based Doubly fed Induction generator (DFIG) using vector control

Abstract

Abstract This Paper shows behaviour of the Doubly fed Induction generator(DFIG) for extracting the maximum power using vector controlled mechanism. This paper present the controlling of rotor side converter(RSC) and grid side converter(GSC) through conventional method of gate triggering by using d-q theory The paper includes the simulation model of DFIG and further the maximum power extraction from wind is estimated by using power coefficient which is completely dependent on pitch angle, tip to speed ratio(TSR). The novelty in power coefficient has design to harness the maximum power. Firstly the mathematical model of DFIG is developed with incorporated wind turbine as mechanical input and then vector controlled method is used. DFIG is broadly used in wind power applications which are more robust, reliable and very efficient system. The complete system is implemented using MATLAB software tool.
