Design and Simulation of Single Phase Shunt Active Filter using MATLAB

Matlab Simulation of Single Phase Shunt Active Filter Based on PQ Theory

ABSTRACTThis paper presents the simulation of single phase shunt active filter based on PQ theory. Generally PQ theory is used for 3 phases 3 wires or 3 phases 4 wire system but here it is used for single phase system. This paper also concentrates hardly on reduction of THD of load current. Since the system has only single phase signal for both voltage and current, thus the dummy signal with 12...

Single-Phase Shunt Active Power Filter Using Indirect Control Method

A single-phase shunt active power filter is used mainly for the elimination of harmonics in single-phase AC networks. In this paper a single-phase shunt active power filter based on, an indirect control technique is designed and simulated. This control technique is achieved by phase shifting the input signal(voltage/current) by π/2.The overall action of the shunt active power filter to eliminat...

Design and Simulation of Three Phase Shunt Active Power Filter Using SRF Theory

Active power filters are widely used for the reduction of harmonics in the power system caused by nonlinear loads. The Shunt Active Power Filter (SAPF) injects a suitable compensating current at a point of the line known as the point of common coupling (PCC) so that the harmonics present in the line are cancelled out and the sinusoidal nature of voltage and current waveforms are restored. A thr...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

Shunt Active Power Filter Design using Genetic Algorithm Method

-This paper deals with the active power filter design controlled by using hysteresis technique. The genetic algorithm is used to design the controllers to minimize the %THD of the source current. The results are compared with that designed from Ingram and Round approach. The simulation results confirm that the genetic algorithm can provide the minimum %THD of the source current compared with th...
