Abstract

The main goal of this paper is to investigate the robustness of some procedures recently proposed in the literature for harmonic pollution metering, in respect to the effects of the uncertainty sources present in the measurement chain. Both single point and multipoint methods are discussed. The research is based on computer simulations performed on an IEEE test system suitable for studies related to harmonics in power distribution networks. The estimate of the combined uncertainty affecting the measurement results is achieved by exploiting a Monte Carlo statistical approach. The results are discussed to highlight some important findings on the practical usability of these monitoring techniques.
