Sawmill loads are disturbing loads. When connected to a power system, they constitute sources of harmonics, voltage fluctuations and flicker. In this paper, measurements of power quality parameters carried out in a case study of MERENSKY Northern Timbers Sawmill Ltd at Tzaneen, Limpopo Province of South Africa are reported. The report indicates that, due to some mitigation measures implemented by...
This paper investigates the impact of supply harmonic voltages on DFIG stator current and power spectra. The influence of individual higher order supply harmonics on DFIG stator current and on total instantaneous power spectral content is investigated using a time-stepped circuit model. The observed effects are identified in experimental data obtained from a laboratory test rig. A set of analytical...
