Paper Title - Desing & Simulation Of Shunt Active Power filter Using P-Q Theory For Power Quality Improvement
Nowadays, the active filters represent a viable alternative for controlling harmonic levels in industrial
consumers’ electrical installations. It must be noted the availability of many different types of filter configurations that can
be used but there is no standard method for rating the active filters. This paper focuses on basic principle of SAPF and the
theoretical concepts describing the shunt active power Filter structure and design. The filter controller is based on
instantaneous power theory (p-q theory) and the circuit performing as an inverter with PWM hysteresis control. To validate
the performance of shunt active filters a Matlab-Simulink model was developed. Simulation results are presented which
verifies the power quality of the grid is enhanced.
