Title:
METHOD AND CONTROL ARRANGEMENT FOR CONTROLLING CENTRAL CAPACITORS IN WIND POWER PLANTS
Document Type and Number:
WIPO Patent Application WO/2011/150932
Kind Code:
A3
Abstract:
The present invention relates to a control system and an associated method for controlling an amount of reactive power delivered from a wind power plant to an associated power supply grid, the control system comprising a wind power plant controller and a number of wind turbine controllers each being in communication with said wind power plant controller, wherein the wind power plant controller is adapted to provide a grid voltage reference in response to a required total amount of reactive power to at least one wind turbine controller and operating a Switched Capacitor bank.
