Abstract
A method and a controller for controlling a wind turbine connected to a utility grid are disclosed/ The method includes: detecting whether control data from a central controller are receivable, wherein the central controller is provided for controlling the wind turbine and a plurality of other wind turbines; if it is detected that control data from the central controller are receivable, receiving the control data from the central controller; if it is detected that control data from the central controller are not receivable, receiving the control data from a local controller of the wind turbine; and controlling the wind turbine based on the received control data.
Claims14
A method for controlling a wind turbine connected to a utility grid, the method comprising:
- detecting whether control data from a central controller are receivable, the central controller is provided for controlling the wind turbine and a plurality of other wind turbines;
- receiving the control data from the central controller when the control data from the central controller are receivable;
- receiving the control data from a local controller of the wind turbine when the control data from the central controller are not receivable;
- and
- controlling the wind turbine based on the received control data.
A wind turbine controller for controlling a wind turbine connected to a utility grid, the wind turbine controller comprising:
- a detection unit adapted to detect whether control data from a central controller are receivable, wherein the central controller is provided for controlling the wind turbine and a plurality of other wind turbines;
- a switching unit adapted to switch:
- from receiving the control data from the central controller when it is detected that control data from the central controller are receivable, and
- to receiving the control data from a local controller of the wind turbine when it is detected that control data from the central controller are not receivable;
- and
- a control unit adapted to control the wind turbine based on the received control data.
