Integration of solid-state lead-lag VAr compensator and self-excited induction generator for low cost power generation

Application of inductively loaded current controlled solid-state lead-lag (ICSL) VAr compensator for voltage control of SEIG has been reported in this paper. From both theoretical and experimental results it is observed that the integrated system of ICSL VAr Compensator and SEIG is able to supply power to wide range of loads at constant output voltage with acceptable supply frequency variation. The system is proposed for application in renewable energy conversion where the SEIG can be driven by unregulated microhydro turbine in constant water head or by wind turbine in a limited range of wind speed variation. The results are critically analysed and the effectiveness of the system for low cost remote area power supply has been discussed in the paper.
