Modelling of doubly fed induction generator connected with a wind turbine

Abstract

There has been a tremendous rise in the use of the renewable energy resources. Global wind energy capacity soared by a fifth to 238GW at the end of 2011. India is the 5th largest player globally, accounted for 16 GW. Wind energy is an important form of renewable energy as there is no greenhouse gas emission compared to non-renewable fossil fuels. There has been a rising demand for wind energy ever since its first implementation.This project work studies the power-speed characteristics and the torque-speed characteristics and the fundamentals of wind electrical systems along with the modeling of the various wind turbine features and simulation of the same using MATLAB-SIMULINK. This paper develops a simple DFIG wind turbine model . This paper deals in conversion theory of (d – q) model . By using the equations of d-q model, dfig equations are simulated in matlab Simulink .
