Abstract:

Power quality is an important issue now a days. Especially in distribution network, where different loads are connected through power system network. They disturb quality of voltage and current of the distribution system like voltage sag, swell, harmonics in current and voltage, reduce power factor etc. thereby load draw excessive current for same power output with increase copper losses, reduce efficiency of system, produce excessive heat due to in nonlinear load condition produce pulsation in torque in dynamic load condition and also create disturbance in power quality of neighboring loads. For solution of these entire problems a reactive power compensation device is required. So here put up the work on Shunt Active Power Filter to improve the power quality problems. Shunt Active Power Filter to improve power factor and THD of source current in inductive and nonlinear load respectively. The Fuzzy logic controller based control scheme is used for Shunt Active Power Filter. Fuzzy logic can deal with virtually any proposition expressed in natural language. The input and output membership functions are applied with 49 fuzzy If Then weighted rule bases was designed to maintain the capacitor voltage constant by providing the required reference current amplitude.
