Multilevel Statcom Based on PID and Fuzzy Control


To investigate the performance of Multilevel STATCOM based on PID with fuzzy controller under fault conditions. Static Synchronous Compensator is used to inject voltages by regulating DC link voltages in the system which consists of two standard inverters associated in cascaded to obtain five level output. Generally DC link voltages are controlled by PI controller. When there is a fault occurrence in the system, then time response of PI controller will be slow and overshoot problems raised. To rectify this problem, PID with fuzzy controller is proposed. By using PID with fuzzy controller, DC link voltages are synchronized; a dq reference frame theory is used in this system for STATCOM to recompense the harmonics. The proposed controller gives less Total Harmonic Distortion, Response Time, Settling Time and Rise Time.
