Abstract
A method is disclosed for determining an individual maximum power level for one or more wind turbines in a wind power plant. The method comprises storing a wind turbine type maximum power level for one or more types of the one or more wind turbines, storing one or more fatigue load values relating to a range of power levels for each of the one or more types wind turbine, and storing one or more parameters relating to site conditions at the wind power plant. The method further comprises determining, based on at least the stored one or more fatigue load values and the stored one or more parameters, the individual maximum power level for each wind turbine of at least a first type of the one or more types.

A method for determining an individual maximum power level for one or more wind turbines in a wind power plant, the method comprising:
- storing a wind turbine type maximum power level for one or more types of the one or more wind turbines;
- storing one or more fatigue load values relating to a range of power levels for each of the one or more types;
- storing one or more parameters relating to site conditions at the wind power plant;
- and
- determining, based on at least the stored one or more fatigue load values and the stored one or more parameters, the individual maximum power level for each wind turbine of at least a first type of the one or more types.
An apparatus for determining an individual maximum power level for one or more wind turbines in a wind power plant, the apparatus comprising:
- a memory adapted to:
- store a wind turbine type maximum power level for one or more types of the one or more wind turbines;
- store one or more fatigue load values relating to a range of power levels for each of the one or more types;
- and
- store one or more parameters relating to site conditions at the wind power plant;
- and
- one or more processors adapted to determine, based on at least the stored one or more fatigue load values and the stored one or more parameters, the individual maximum power level for each wind turbine of at least a first type of the one or more types.
A method comprising:
- simulating a load spectrum for two or more test power levels to determine a respective load on a wind turbine type for each test power level of the two or more test power levels;
- comparing the determined load for each test power level with a design load for the wind turbine type;
- setting a wind turbine type maximum power level for the wind turbine type as a maximum test power level of the two or more test power levels at which the determined load does not exceed the design load for the wind turbine type;
- storing one or more fatigue load values relating to a range of power levels for the wind turbine type;
- storing one or more parameters relating to site conditions at a wind power plant;
- and
- determining, based on at least the stored one or more fatigue load values and the stored one or more parameters, an individual maximum power level for the wind turbine type.
