-This paper presents an approach based on Response Surface Methodology (RSM) to find the optimal parameters of the single-tuned passive filters for harmonic mitigation. The main advantages of RSM can be underlined as easy implementation and effective computation. Using RSM, the single-tuned harmonic filter is designed to minimize voltage total harmonic distortion (THDV) and current total harmonic distortion (THDI). Power factor (PF) is also incorporated in the design procedure as a constraint. To show the validity of the proposed approach, RSM and Classical Direct Search (Grid Search) methods are evaluated for a typical industrial power system.

This paper analyzes and proposes technical considerations for the selection and design of passive filter schemes rated at several mega-vars to compensate reactive power and current harmonics in mining power distribution systems. The paper includes technical information and analysis required to select the most adequate passive filter topology, to select the tuning frequency for each unit, to calculate filter parameters, and to distribute reactive power between passive filters. Passive filter schemes analyzed in this paper are used to compensate mining power distribution systems, especially when high power grinding mill drives energized from 12-pulse cycloconverters are used in conjunction with several other nonlinear loads. The manuscript also analyzes technical limitations that passive filters present in the attenuation of low frequency current harmonics. Finally, two power distribution systems with different passive filters schemes are evaluated, and the limitations in the attenuation of low frequency current harmonics generated by cycloconverters are demonstrated with measured results.Index Terms-Passive filters, mining power distribution, current harmonic compensation, sub and inter-harmonic components, cycloconverter drives, power quality.

“…To improve the power factor, two techniques are proposed in literature i.e. passive filters and active filter [9]- [12]. The required rating of these filters can be as high as 50% of the rectifier kVA rating [12].…”

“…Because of this reason (high cost), passive filter becomes more attractive as compared to active filters. Passive filters applied to variable-voltage rectifiers are mainly designed for compensating reactive power (to improve input displacement power factor) [9], [10]. This leads to significantly high reactive power rating of the filter.…”

This paper presents a thyristor-based tap changing transformer and diode rectifier for variable-voltage highcurrent DC applications. Back to back thyristors are connected in series with the transformer taps on the primary side. Thyristors are phase-controlled in a continuous manner to achieve variable AC voltage at the secondary side of the transformer. This leads to a variable DC voltage at the output of three-phase diode rectifier connected at the secondary side of transformer. A passive filter is added at the primary side to achieve power factor improvement over the range of output voltage. This scheme is optimized to determine optimum turns ratio of the transformer and optimum reactive power rating of the passive filter. Design guidelines are presented for various values of power factor along with optimum turns ratios and passive filter rating. A 62.5 kW experimental system with passive filter of 17.5 kVA (reactive) is developed to verify the system performance. In the end, a comparison of the proposed topology with other state of the art topologies is also presented.
