In this paper, single control loop based scheme for regulation of voltage and frequency of Self Excited Induction Generator (SEIG) based stand-alone 3-phase 4-wire renewable energy conversion system under source and balanced/unbalanced load perturbations is presented. The regulation is accomplished by maintaining reactive and active power balance across individual phases of SEIG using a Generalized...
This paper describes the implementation of multirate sampling technique for carrier space vector pulse width modulation based direct torque control (CSVPWM DTC) of induction motor (IM) drive with an objective to reduce the electromagnetic torque ripple. The benefit of the proposed technique for CSVPWM DTC based IM drive; it gives lower torque ripple as compared to single rate sampling technique. In...
In this paper, a UPF power conditioner for an optimal extraction of output power from grid connected variable speed wind energy conversion system (VSWECS) is presented. The system consists of a variable speed wind turbine coupled to a permanent magnet synchronous generator (PMSG) through a gear box, two PWM power converters and a maximum power point tracker (MPPT). Output power from PMSG is first...
