Applied research work to identify an alternative voltage control
solution for a 60MW 132kV connected windfarm, in a complex
network with a high degree of legacy generation.
A 132kV-connected windfarm is being investigated with aim to
control real and reactive power flow to maintain the 132kV system
voltage at the wind farm substation to within the range +7%, -4%.
Currently if the windfarm is unable to maintain voltage to within
these limits a trip signal is automatically sent by the DNO to the
open the connecting circuit breakers.
The existing network is weak and subject to high network losses.
The windfarm manages voltage control to stay connected within the
