A study of the measurement chain in the power active filters. Uncertainty and control performances

摘要

Active filters represent one of the most performant solutions for improving power quality in distribution networks. The development of active distribution grids imposed new requirements for active filters, as they are installed in points of common coupling (PCC) and considering that the grid parameters can change in time. In the paper a thoroughly approach of the measurement chain and associated uncertainties is going to be presented, together with a set of recommendations for a more robust design.
