Abstract
Wind turbines with induction generators consume reactive power.
Apart from the no load consumption, which is nearing constant and
is being compensated for using capacitors, the consumption of
reactive power varies almost proportional with the power
production, which can vary immensely. Except that the supply line
must deliver the reactive current with ensuing losses, the strong
variation also will cause varying inductive voltage losses in the
supply with flicker as a consequence. With power electronic
equipment it is possible to produce the reactive power on location
and reduce the losses and voltage fluctuations in the line. In the
paper a description is being given of a 100 kvar power electronic
reactive power compensator built by SILCON Ltd and Technical
University of Denmark in cooperation with ELSAM and Nordkraft. The
compensator was tested connected to three wind turbines in a
windmill farm in Western Denmark. The electrical circuit and the
working principle of the compensator are described and some
measurements are given. Further is being described a 2x4 Mvar
reactive power compensator placed in another wind mill farm on
totally 24 WM in Western Denmark for compensating the whole farm.
Commissioning of the compensator is planned to January 1997. The
compensator is a result of an EU-project with participation of
SIEMENS (D), who is constructing the compensator, ELSAM (DK), SH
(DK), UMIST (UK) and DTU (DK).
