摘要

A method for the operation of a variable-speed wind turbine having pitch and torque control means that includes additional steps for providing to the torque control means, in case of an environmental situation where the air density Á is greater than a predetermined value Á ref , i.e. a situation combining low temperature and low height, a reduced nominal generator speed © nr , instead of the rated nominal generator speed © n , which is determined dynamically as a function of at least the air pressure Pr, the temperature T and the wind speed V, for decreasing the wind turbine loading. The invention also refers to a control system arranged for performing said regulation.
