Grid isolating wind farm control

Abstract:

Disclosed is a method of controlling wind turbines of a wind farm, each connected to a wind farm grid, in case of a disconnect from a main grid. During the disconnect from the main grid, at least one demand value is transmitted from a digital master grid controller to respective converter units of the wind turbines via a digital data link such that the converter units receive the at least one demand value substantially simultaneously and are operable to keep the wind turbines online and synchronised to the wind farm grid during the disconnect from the main grid.
