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...
متن کاملMatlab 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...
متن کاملAdaptive Hysteresis Current Control of Shunt Active Filter for Three Phase Four-wire System
In a balanced three phase system, only harmonics of positive sequence(7 th , 13 th ,..etc) and negative sequence (5 th , 11 th ,…etc) are produced. However, the harmonic currents produced by single phase non-linear loads like switch-mode power supplies in computer which are connected between phase to neutral injects third order zero sequence harmonics (3 rd ,9 th ,15 th …etc) (Mehmet et al 2008...
متن کاملOptimum Control Strategy of Three-Phase Shunt Active Filter System
The aim of this paper is to identify an optimum control strategy of three-phase shunt active filters to minimize the total harmonic distortion factor of the supply current. A classical PIPI cascade control solution of the output current of the active filter and the voltage across the DC capacitor based on Modulus–Optimum criterion is taken into consideration. The control system operation has be...
متن کاملModelling of Three-phase Shunt Hybrid Active Power Filter
The three-phase Shunt hybrid APF topology for harmonic mitigation in low and medium voltage power distribution systems consists of a VSI based three phase shunt active filter (SAF) and tuned passive filters (TPF) connected in parallel with the load. This chapter discusses the modelling of shunt active filter and design of filter interfacing inductor, DC bus capacitor, tuned passive filters. It ...
