Supervision of DC Link Pi Control In A D-Statcom Based on Fuzzy Logic
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2013, Vol 1, Issue 7
Abstract
PI controller with control algorithms are used for load compensation and voltage regulation in D-STATCOM. Because of variation in dc capacitor voltage, load changes might affect the compensation. In this paper, a fuzzy logic based supervisory method is proposed to improve the transient performance of the dc link. Proportional and integral gains of the PI controller varies the transient period time immediately after the load variation. PI gains using expert knowledge of system behavior and higher sampling during the transient period improves the performance of the controller. Error in dc link reduces capacitor voltage during load change compared to normal PI controller. Efficiency and settling time of voltage is also fast, will be proved using this proposed approach with MATLAB simulation results.
