“…The PHFs are commonly used in practice because they are low cost, simple in structure, easy to maintain, very efficient in terms of individual harmonic reduction, and easily applicable in low voltage (LV), medium voltage (MV), and high voltage (HV) systems [28][29][30][31]. But in comparison to the shunt active power filter (SAPF) and HAPF, they are less efficient in terms of power quality improvement and their work efficiency in terms of harmonics mitigation depends (in certain cases) on the grid impedance [32,33].…”

This paper presents a case study in which the influence of the 6-pulse thyristor-bridge input reactor size on the shunt active power filter (SAPF)’s work performance is investigated. The purpose of using an SAPF in the power system is in most cases for fundamental harmonic reactive power compensation, harmonics and asymmetry mitigation. The work efficiency of such a filter depends not only on the designed control system, interface filter and dc-link capacitor parameters, but also on the parameters of the electrical system in which it is connected. Therefore, it is necessary to study and know the power system (supplier and consumer sides) before its installation. For instance, in the electrical system with diode or thyristor-bridge as loads, the SAPF performance efficiency may not be satisfied due to the high rate of current change (di/dt) at the points of commutation notches. In this paper, the performed simulation and laboratory experiments show that for a better operating efficiency of the SAPF, the input reactor parameters should be selected based not only on the effective reduction in the inverter switching ripple or the control system demand, but also on the parameters of the load, such as the parameters of the diode or thyristor-bridge input reactor. Apart from the experimental demonstrations on how the input reactor size influences the SAPF work efficiency, the novelties in this paper are: the formulated recommendations on how to choose the SAPF input reactor parameters (the SAPF is more efficient in terms of harmonics, asymmetry and reactive power mitigation when the inductance of its input reactor (L-filter) is smaller than the one of the diode or thyristor-bridge input reactor); the proposed SAPF control system; the proposed expressions to compute the SAPF input reactor inductance, DC voltage and capacitor.

“…The growth of nonlinear loads causes distortions in the current and voltage waveform [2][3][4], which are represented as harmonics. These harmonics may have several adverse effects on power systems, including power loss, power factor reduction, equipment malfunctioning, deterioration, and damage [5][6][7][8][9][10][11]. Several techniques, utilizing components such as reactors and chokes, active power filters (APFs), passive power filters (PPFs), different transformer connections, and a higher pulse number converter, have been developed to solve these problems.…”

Harmonic distortion in power systems is a significant problem, and it is thus necessary to mitigate critical harmonics. This study proposes an optimal method for designing passive power filters (PPFs) to suppress these harmonics. The design of a PPF involves multi-objective optimization. A multi-objective bee swarm optimization (MOBSO) with Pareto optimality is implemented, and an external archive is used to store the non-dominated solutions obtained. The minimum Manhattan distance strategy was used to select the most balanced solution in the Pareto solution set. A series of case studies are presented to demonstrate the efficiency and superiority of the proposed method. Therefore, the proposed method has a very promising future not only in filter design but also in solving other multi-objective optimization problems.

The use of switch mode power supply (SMPS) load such as computer, laptop, etc in residential as well as commercial areas give rise to harmonics pollution in the electrical power distribution system which causes the quality of power poor and the function of equipment connected to the electrical system is affected. Many electrical appliances have an SMPS design that characteristically draws a distorted current that flows back to the input supply and causes distortion in the voltage waveform. To ensure the safe functioning of various electrical devices, there is a need for the implementation of effective harmonics mitigating techniques. Passive filters have been used for mitigating voltage and current harmonics. This paper proposed an analytical approach to designing the passive filter instead of trial and error or a complex approach for harmonics mitigation. The Simulation Model of SMPS is developed in MATLAB/Simulink and used for validating the proposed approach. Simulation results show the attractive findings of the proposed approach for harmonic mitigation with the improvement of the power factor.
