Abstract
A method of operating a wind turbine is provided. The method includes steps of monitoring the temperature of a component of the wind turbine to obtain a temperature progression for that component; determining the gradient of the temperature progression; and curtailing the power output of the wind turbine on the basis of the temperature progression gradient. The disclosed further describes a wind turbine including a curtailment module configured to curtail the power output of the wind turbine on the basis of a temperature progression gradient.
Claims15
A method of operating a wind turbine, which method comprises:
- monitoring the temperature of a component of the wind turbine to obtain a temperature progression for that component;
- determining the gradient of the temperature progression;
- and
- curtailing the power output of the wind turbine on the basis of the temperature progression gradient, wherein the amount of curtailment is proportional to the gradient of a temperature progression.
A wind turbine comprising
- a temperature monitoring arrangement configured to monitor the temperature of a component of the wind turbine;
- and
- a controller including
- a processing module configured to determine the temperature progression of the monitored temperature and to determine the gradient of the temperature progression;
- and
- a curtailment module configured to curtail the power output of the wind turbine on the basis of the temperature progression gradient, wherein the amount of curtailment is proportional to the gradient of a temperature progression.
The wind turbine according to 19, temperature monitoring arrangement comprises at least one temperature sensor arranged in proximity to a region of thermal significance of a component.
