Abstract
Genetic Algorithm toolbox (GA) provided by MatLab software is selected to find the optimal sizing of parameters of C-type passive filter. The optimal design of the proposed filters considers three optimization problems- minimization of the total current, voltage harmonic distortion and maximizing power factor. Each optimization problem considers practical constraints such as load power factor , total current and voltage harmonic distortion limitation at certain specified ranges, considering source and load nonlinearities, while taking into account compliance with IEEE Standard 519-1992 and IEEE Standard 18-2002. Finally, the effectiveness of C-type harmonic passive filters is demonstrated by means of various study cases, including a comparison between the results of the three objective functions. A comparative study between C-type filter and single tuned passive filters is represented, comparing with the uncompensated system configuration under non-sinusoidal conditions
