| Abstract |
Active power filters (APFs) are an effective tool against several disturbances affecting the electric grid. Their proper operation ensures a general increase of power quality on the grid and as a consequence they avoid that disturbances generated by highly polluting loads may affect other users. If remedies were applied by a large amount of facilities and customers, distorted waveforms would be bounded to a restricted area and could not propagate across the electric grid. Nowadays a large debate is still open among the researchers on how to share the responsibility on the power quality deterioration between customers and utilities. Perhaps in the future electrical utilities will introduce tariffs to penalize customers who are responsible for a big amount of harmonic distortion. Today this does not happen. For this reason highly polluting customers don’t realize any kind of economic convenience in using such devices. So the aim of this work is to find a solution to achieve active filters cost reduction. The proposed solution, relevant to single phase non-linear loads, relies on using both a current reference different from the classical one and a fuzzy logic based control technique. Proposed approach allows proper disturbance compensation with lower switching frequency and low power level involved as pointed out by simulation results. |
