“…The problem of symmetrisation has already been considered in the available publications for three-phase systems mainly. Issues of symmetrisation of systems for different types of deformations have already been discussed in many publications (works [1][2][3][4][5][6][7] refer to sinusoidal deformations and works [8][9][10][11] refer to periodic deformations). In later works the problem of symmetrisation has been considered for N-phase systems as well for three phase systems with simplified structure of the symmetrising system [12][13][14][15].…”

The research work has principally been related to selected problems in the field of analysis and synthesis of systems aimed at symmetrisation and improvement of some power quality parameters. This paper constitutes the second part of the report on the research. It has been devoted to three-phase system symmetrisation as well as effective elimination of higher harmonics and substantial improvement of power quality by means of hybrid active power filters.

“…Nonlinear loads cause harmonic distortion within the voltage and current waveform in the power system. Harmonics result in numerous problems such as low power factor and overheat on the power systems, electrical devices and transformers (Lee and Wu 1998; Snal et al 2004; Hamadi et al 2010; Sekkeli and Tarkan 2013). In order to protect other users in power system from the effects of the harmonics caused by nonlinear devices, the IEEE 519-1992 standard has imposed specific limits on levels of voltage and current harmonics.…”

Harmonics is one of the major power quality problems for power systems. The harmonics can be eliminated by power filters such as passive, active, and hybrid. In this study, a new passive filter configuration has been improved in addition to the existing passive filter configurations. Conventional hybrid passive filters are not successful to compensate rapidly changing reactive power demand. The proposed configure are capable of compensating both harmonics and reactive power at the same time. Simulation results show that performance of reactive power and harmonic compensation with advanced hybrid passive filter is better than conventional hybrid passive filters.

“…In the works presented earlier, the problem of symmetrization for periodic non-sinusoidal waveforms has been considered mainly for three-phase systems supplied from ideal (Klinger, 1979;Szidlowskij and Kuzniecov, 1985;Pasko, 1991;Czarnecki, 1992) and non-ideal (Pasko and Debowski, 1997;Lee and Wu, 1998;Nedeljkovic et al, 1999;Hsu and Czarnecki, 2000;Chindris et al, 2001), sinusoidal and periodic non-sinusoidal voltage sources. It has also been considered for multi-phase systems supplied from ideal periodic non-sinusoidal voltage sources (Pasko and Debowski, 2002).…”

Purpose -The problems presented in the paper concern a three-phase four-wire system with periodical non-sinusoidal voltage sources with inner impedances and asymmetrical linear three-phase loads. Generally, the line currents of the system are asymmetrical. The purpose of the paper is to improve the working conditions of the system by means of symmetrization. Design/methodology/approach -A method of symmetrization of these systems has been proposed. In this paper, the symmetrization problem has been solved by using the symmetrical components theory and compensation of reactive power for each of voltage harmonics under consideration. Findings -After symmetrization currents become symmetrical and their RMS values and active power on source impedances become lower. The realization of symmetrization makes possible: reduction of RMS values of source currents, an assurance of equal loads for individual phases of the system supplied from sources with inner impedances, after symmetrization the voltage source generates and load consumes greater useful active power. Originality/value -The simplified structure of the compensator has been proposed in the paper. The symmetrization has been presented with reference to new structure of the compensator.
