Abstract

A power system reduction method is described for use in harmonic state estimation (HSE). The new method uses harmonic measurements at non-harmonic-source buses, such as those of generators, without loads or linear loads, to estimate the system-wide harmonic levels. In general, non-harmonic-source buses are more numerous and accessible, and are also better equipped with measurement instruments than those of remote and non-linear loads. The new solution provides optimal measurement locations thus reducing the monitoring costs attached to harmonic state estimation. The enhanced HSE algorithm has been tested in the New Zealand power system with promising results. (C) 2000 Elsevier Science S.A. All rights reserved.
