HARMONIC CURRENT COMPENSATION IN SELF EXCITED INDUCTION GENERATOR USING ACTIVE FILTER

The Self-Excited Induction Generator (SEIG) is more suitable for wind energy conversion systems in remotely located areas. The system consists of squirrel cage induction machine coupled with wind turbine through a gear box, Voltage Source Converter (VSC) as active power filter, fixed capacitor bank and diode rectifier with RL load. SEIG feeding nonlinear load causes current harmonics in the generator current. This paper focuses on minimizing the current harmonics to some extent using shunt Active Power Filter. The performance of the wind turbine driven self-excited induction generator is analyzed with shunt active filter for supplying nonlinear load. The system is designed and simulated using MATLAB Simulink environment. It is also verified with experimental results obtained with prototype hardware model.
