In recent years, shunt hybrid active power filters are being increasingly considered as a viable alternative to both passive filters and active power filters for compensating harmonics. In literature, their applications are restricted to balanced systems and low voltage applications and therefore not for industrial applications. This paper investigates the performance of a modular cascaded multilevel inverter based Shunt Hybrid Active Power Filter (SHAPF) for reactive power compensation and selective harmonics elimination under distorted/unbalanced grid voltage conditions in medium voltage levels. In the proposed control method, reactive power compensation is achieved successfully with a perceptible amount and the performance results of harmonic compensation are satisfactory. Theoretical analysis and simulation results are obtained from an actual industrial network model in PSCAD. The simulation results are presented for a proposed system in order to demonstrate that the harmonic compensation performance meets the IEEE-519 standard.

A novel hybrid series active power filter to eliminate harmonics and compensate reactive power is presented and analyzed. The proposed active compensation technique is based on a hybrid series active filter using ATS algorithm in the conventional Sinusoidal Fryze voltage (SFV) control technique. This chapter discusses the comparative performances of conventional Sinusoidal Fryze voltage control strategy and ATS-optimized controllers. ATS algorithm has been used to obtain the optimum value of Kp and Ki. Analysis of the hybrid series active power filter system under non-linear load condition and its impact on the performance of the controllers is evaluated. MATLAB/Simulink results and Total harmonic distortion (THD) shows the practical viability of the controller for hybrid series active power filter to provide harmonic isolation of non-linear loads and to comply with IEEE 519 recommended harmonic standards. The ATS-optimized controller has been attempted for shunt active power filter too, and its performance has also been discussed in brief.

Traditionally, the major part of the electrical power is generally consumed by the non-linear loads due to frequent application of the semiconductor devices in the form of domestic and industrial loads. This results from distortion in the actual supply voltage waveform at the source end due to the interference of the multiple harmonics generated out of semiconductor devices used at load end and excessive absorption of the reactive power. The insufficiency of these compensation techniques leads to the advent of the phase multiplication techniques as well as the most reliable and economic active power filtering scheme. A deep analysis showing tedious waveforms using the ORCAD simulation package for the various kind of loads in conjunction with the single-phase active power filter shunted to the single-phase line at the load end for the two current control techniques (i.e., hysteresis band current control, triangularization of current control) has been done. The results are analyzed and tested to lead the optimistic approach for APF (active power filters).

Simulation Results

Passive power filter (PF) has problems that source impedance may strongly affect the filtering characteristics and cause system resonance in power system applications. Hybrid active power filter (HAPF) can improve the performance of passive filter and realize harmonics restraint and reactive power compensation in big power situation. In this paper, the principle of HAPF is analyzed, the model of HAPF is established, and the simulation results are discussed.
