Abstract

Presents the dynamic modelling of variable speed constant frequency [VSCF] wind energy conversion scheme [WECS], employing self excited induction generator, connected to the utility grid through an AC-DC-AC converter scheme with uncontrolled rectifier and PWM inverter. The proposed scheme for regulating the flow of power through the link ensures reduced reactive power burden on the self excitation capacitor banks, reduced harmonic injection into the host power utility grid and efficient utilization of available wind energy. Modelling of the subsystems and simulation of the unified system with pulse width modulated [PWM] inverter control, to reduce harmonics injected into the utility grid are also presented
