Voltage Regulation of Non Linear Load Using STATCOM with Fuzzy Technique

V. Bala, Dr. K. Elango

Abstract: In distribution systems, sudden change in load draws non-sinusoidal currents and causes the load harmonics, excessive neutral currents creates disturbance and changes in Power factor. Static Synchronous Compensator (STATCOM) is used to provide reactive power to the transmission line. In this paper proposes with Fuzzy Logic Controller (FLC) to tune PI controller gain values under different operating condition. Tuned values operate with PI controller and provides gate signal to voltage source converter which decides amount of reactive power to be injected into bus. Power factor value also improved. This method not affected by the initial gain settings, changes of system conditions and produces better and desired response. By providing reactive power and power factor correction system performance increased and also improves voltage regulation.

Keywords: Fuzzy logic controller, PI controller, STATCOM, Voltage regulation, Power factor correction, Reactive power compensation, non linear load
