Analysis of Self Excited Induction Generator Driven By Wind Turbine System Using Current Source Inverter Technology

Abstract

This paper describes the simulation model and the harmonics analysis of Current Source Inverters fed RL load. The SEIG fed PWM Current Source Inverter for variable speed wind energy conversion systems are considered for various stand-alone applications. In this paper, the SEIG fed IGBT PWM Inverter for RL load system are clearly explained with the help of MATLAB/SIMULINK models. The generated voltage of wind driven self-excited induction generator (SEIG) is mainly depending on the wind velocity fluctuations, suitable capacitance magnitude and load conditions. The PWM Inverter has interface with the wind driven self-excited induction generator. The main objective of this paper is to extract maximum power from the generator to the grid connected wind energy conversion system. The variable magnitude, variable frequency voltage of the generator can be controlled by choosing the proper modulation index. The simulation analysis of the proposed inverter will be discussed and the total harmonic distortion will be evaluated.
