Application of Solid State Transformer in DFIG Based Wind Energy Conversion System

In wind energy systems the central frequency transformer goes about as a key component between the WECS and the grid As of late there have been endeavors to supplant this transformer by a power electronics based solid state transformer This paper aims to provide a setup that incorporates the doubly fed induction generator based wind energy conversion system and Solid state transformer operation The principle target of the proposed setup is to combine the turbine with the grid while giving upgraded efficiency and performance .In this configuration SST controls the real power flow to/from the rotor side converter therefore taking out the grid side converter. The proposed framework meets the ongoing grid code necessities of wind turbine activity under fault conditions A definitive simulation is done in MATLAB to approve the execution of the proposed configuration and a prototype of the setup is also built
