“…21 Considering the total installation costs of the C-type filter and the conventional single-tuned passive filter presented in Abdel-Aziz et al, 15 Figures 9 and 10 show installation cost comparison between the two filters for the system under study in Cases 1 and 3, respectively. The conventional single-tuned passive filter data are taken from Zobaa et al 6 and Abdel-Aziz et al 15 However, it must be mentioned that the equivalent resistance of the reactor at fundamental frequency was ignored in Zobaa et al 6 and Abdel-Aziz et al 15 ; thus, in the comparison it is assumed to have the smallest acceptable value of 1% of the fundamental value of the compensator reactor. This allows it to be taken into account in the results rather than being neglected.…”

“…It has been shown that under distorted supply voltages, any trial to increase the power factor results in an increase in the ITHD. 6,18 However, the individual harmonic supply currents and the TDD percentage meet the standard limits defined in IEEE 519.

“…Degradation of the load power factor, increases in transmission line losses, and reduction of the transmission network efficiency are all expected due to the advance and sophistication of nonlinear loads; the level of voltage harmonic distortion in distribution networks will also increase significantly.

Among these solutions, shunt passive filters are the most frequently employed in power-quality markets because of their low cost, which represents the main interest of most users, in the case of power factor © Islam F.

Abstract:In the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance, and compensating reactive power in order to improve the load power factor while taking into account economic considerations. Optimal sizing of the C-type filter parameters based on maximization of the load power factor as an objective function is determined. The total installation cost of the C-type filter and that of the conventional shunt (single-tuned) passive filter are comparatively evaluated. Background voltage and load current harmonics are taken into account. Recommendations defined in IEEE standards 519-1992 and 18-2002 are taken as the main constraints in this study. The presented design is tested using four numerical cases taken from previous publications, and the proposed filter results are compared with those of other published techniques. The results validate that the performance of the C-type passive filter as a low-pass filter is acceptable, especially in the case of lower short-circuit capacity systems. The C-type filter may achieve the same power factor with a lower total installation cost than a single-tuned passive filter.
