Performance Analysis of Self Excited Induction Generator Based Stand-Alone Wind Energy Conversion System

Abstract

The wind energy system is rapidly developing as one of the most favourable renewable energy sources in the present scenario. Due to the constant research in the field of wind energy related technology and generic growth in power electronics system, wind power generation becomes simpler and economical. For low power wind energy system, SEIG is a good choice as a wind power generator. It has lower cost compared to other generator, lower maintenance demands and natural protection against short circuit. The project mainly focuses on the dynamic analysis and modelling of self-excited induction generator used for low power wind energy system. A wind turbine emulator model using torque imitation scheme is developed to drive the IG using MATLAB/Simulink environment. WTE gives the real characteristics as of a wind turbine for better analysis of SEIG under roof. The dynamic performance of SEIG is carried through Simulink and the validation of the Simulink results are established by experiment.
