Sammendrag
This paper discusses cause and effect of harmonic voltages
and severe lighting equipment flicker that were observed by
low voltage end consumers in connection with the operation
of a pumping station connected to a 22 kV radial line of a
typical MV distribution network of a Norwegian utility. The
pumping station, consisting of three wound-rotor induction
motors rated at 1.75 MW, 6.6 kV, forms part of a local
medium-size hydro power scheme. The voltage disturbance
is a 7.harmonic (and partly 5.harmonic) component
fluctuating with a frequency of approximately 2 Hz,
resulting in considerable flicker problems in lighting
equipment at end customers, causing customer complaints.
