Harmonic Analysis of Doubly Fed Induction Generator for Wind Energy Conversion Systems Using MATLAB/Simulink

Y.Mastanamma, S.Deepthi

In order to meet power needs, taking into account economical and environmental factors, wind energy conversion is gradually gaining interests as a suitable source of renewable energy. A Wind Energy Conversion System (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas the power output of a WECS depends on the wind. In this paper the steady state characteristics of a WECS using doubly fed induction generator (DFIG) is proposed and simulated Wind Turbine and doubly-fed induction machine used in generating mode to produce electrical energy on a power network. Simulation analysis is performed to investigate harmonic analysis for DFIG based WECS.
