On the AC-Side Interface Filter in Three-Phase Shunt Active Power Filter Systems
The proper selection of the AC-side passive filter interconnecting the voltage source converter to the power supply is essential to obtain satisfactory performances of an active power filter system. The use of the LCL-type filter has the advantage of eliminating the high frequency switching harmonics in the current injected into the power supply. This paper is mainly focused on analyzing the in...
متن کاملDesign of Three-Phase Hybrid Active Power Filter for Compensating the Harmonic Currents of Three-Phase System
Power quality standards (IEEE-519) require to limit the total harmonic distortion within satisfactory range caused by power electronic based devices. Our work deals with the design of hybrid active filter to reduce current perturbations produced by power electronics based devices. The Instantaneous Active and Reactive Power Method (pq) is used to perform the identification of disturbing current...
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 کاملShunt Active Power Filter with Hysteresis Current Control for three Phase Ac-Dc Converter
This paper represents the simulation of Shunt Active Power Filter(SAPF) based on p-q theory and using hysteresis current control to obtain the gating signals for three phase ac-dc converter. The proposed active power filter is employed to reduce the current Total Harmonic Distortion (THD) drawn by the non-linear load and compensate the reactive power. The PI controller is employed to reduce the...
متن کاملFrequency Estimation of Unbalanced Three-Phase Power System using a New LMS Algorithm
This paper presents a simple and easy implementable Least Mean Square (LMS) type approach for frequency estimation of three phase power system in an unbalanced condition. The proposed LMS type algorithm is based on a second order recursion for the complex voltage derived from Clarke's transformation which is proved in the paper. The proposed algorithm is real adaptive filter with real parameter...
