Abstract
Official abstract text for this publication.
A wind turbine and a method for controlling the temperature of a wind turbine generator are disclosed, the wind turbine comprising a generator, generator temperature control means and means for providing input representative of at least one temperature of the generator to the generator temperature control means, the generator temperature control means including a closed-loop regulation arranged to determine a deviation of the input from at least one desired value, compute the magnitude of at least one control output in dependency of the determined deviation, and feed the control output to at least one controller of the wind turbine in order to reduce the deviation, the controller comprising control means for controlling the operation of the wind turbine in response to the at least one control output by changing one or more operational parameters of the wind turbine, which parameters influence the at least one temperature of the generator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wind turbine, comprising: a wind turbine rotor comprising one or more blades, a generator coupled to the wind turbine rotor, a yaw actuator configured to adjust a yaw angle of the wind turbine, a generator temperature controller, and an estimator configured to estimate a temperature of the generator using a measured value of at least one of stator and rotor currents associated with the generator and provide the estimated temperature to the ge…
