Comparison of Current Control Strategies for Three- level Four-leg Shunt Active Power Filter
This paper presents a comparison of two control strategies for 3-level 4-leg Shunt Active Power Filter (SAPF). The first method is based on hysteresis controllers. The second, proposed method is the Model Predictive Control (MPC) with a finite control-states set (FS) based on phase-to-phase model. The two methods are described and simulation results are presented and analyzed. Comparison is per...
متن کاملHybrid direct power/current control using feedback linearization of three-level four-leg voltage source shunt active power filter
Introduction The excessive use of power electronic equipments, which represent nonlinear loads, in a distribution network has caused many disturbances in the quality of power such as harmonic pollutions, unbalanced load currents, and reactive power problems. As a result poor power factor, weakening efficiency, overheating of motors and transformers, malfunction of sensitive devices etc. are enc...
متن کاملA Comparative Performance Analysis of Four Control Algorithms for a Three Phase Shunt Active Power Filter
Shunt Active Power Filters (SAPFs) represent the most important and widely used filter in industrial purposes due to the fact that, they not only eliminate the harmonic current with a neglected amount of active fundamental current supplied to compensate system losses, but also they are suitable for a wide range of power ratings. One of the key issues for a proper implementation of an active fil...
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 ...
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...
