Title:
METHOD AND SYSTEM OF CONTROLLING WIND TURBINES IN A WIND TURBINE FARM
Document Type and Number:
WIPO Patent Application WO/2017/107920
Kind Code:
A1
Abstract:
Method and system for operating a wind turbine farm, comprising a plurality of wind turbines (1) having at least one ambient sensor (8) and at least one operating sensor (10). The wind turbines (1) are in communication with a control unit (2), which in turn is connected to at least one database (3) in which the ambient data and the operating data are stored. The control unit (2) determines a desired first control parameter (11) for controlling a selected wind turbine. A second control parameter (12) is then calculated based on the first control parameter (11) using a relationship (13) between a first operating parameter (11) and a second operating parameter (12). This relationship (13) and a normal second control parameter are used to generate a reduced second control parameter (12) which is transmitted to the selected wind turbine. The control unit (2) monitors the change of the first operating parameter (11) to determine when the selected wind turbine has reached the reduced operating level.
