Two-phase Three-wire Shunt Active Power Filter Control By Using The Single-phase P-q Theory

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...

Current harmonics compensation with three- phase four-wire shunt hybrid active power filter based on modified D–Q theory

This study presents aD–Q current controlmethodwithmodified phase lock loop to generate the required reference current for shunt hybrid active filter (SHAPF) to improve the power quality. The performance of the proposed controller has been evaluated in terms of harmonic current mitigation and reactive power compensation under different grid conditions. Here, the passive elements of SHAPF have be...

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

Modelling 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 ...

Review on Shunt Active Power Filter for Three Phase Four Wire System

This review provides a survey of shunt active power filter based on inverter in three phase four wire system. These topologies are applied to solve problem due to non linear load in power system network such as a power quality issue, reactive power compensation and harmonic current suppression. In making a review it should be noted that this paper will not attempt to give an all encompassing re...
