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, comprising:
- monitoring a temperature of a component of the wind turbine to obtain a temperature progression for the component;
- monitoring an ambient temperature for the component;
- determining a gradient of the temperature progression;
- and
- curtailing a power output of the wind turbine on the basis of the gradient of the temperature progression, wherein an amount of curtailment is proportional to the gradient of the temperature progression;
- and wherein the amount of curtailment is also based on the ambient temperature for the component.
A wind turbine comprising:
- a temperature monitoring arrangement configured to monitor a temperature of a component of the wind turbine;
- an ambient temperature sensor configured to monitor an ambient temperature for the component;
- and
- a controller including
- a processing module configured to determine a temperature progression of the monitored temperature and to determine a gradient of the temperature progression;
- and
- a curtailment module configured to curtail a power output of the wind turbine on the basis of the gradient of the temperature progression, wherein an amount of curtailment is proportional to the gradient of the temperature progression, and wherein the amount of curtailment is also based on the ambient temperature for the component.
