Implementation of Three-Phase Shunt Active Filter Using Instantaneous Real Power Calculation and Triangular Carrier Current Control

摘要

The power quality improvement has been done with a three-phase shunt active filter (ShAF) using instantaneous real power calculation (IRPC) and triangular carrier current controller. Instantaneous real power calculation method uses the instantaneous real power (p) for reference current generation along with the triangular carrier current controller (TCCC) to produce ShAF switching pulses. The harmonics produced by the nonlinear load can be filtered out using the ShAF to a great extent using the proposed control method. The effectiveness of the algorithm is verified using PSIM simulation software for a nonlinear load of 5 kW power fed by distribution of 400 V, 50 Hz system, and then its performance is compared with that of the conventional IRPT algorithm.
