Abstract :
In this paper, various dynamic slip control topologies are proposed for the control of grid connected opti-slip induction generator (OSIG). An elegant technique based on rotor voltage measurement has also been presented for mitigating output power fluctuations from OSIG, due to sudden wind gusts, tower shadow effect, etc. The control of OSIG is achieved using the basic principle of chopper control for varying the rotor resistance. The proposed technique has also been extended to control the amount of real power flow into the grid at the desired value. The proposed dynamic slip control topologies and the control algorithm have been simulated and tested using PSCAD/EMTDC software. The results are presented and discussed in detail.
