Claim 0:
1. A controller for a wind turbine, the controller comprising a power controller unit for controlling a power output of an electric generator comprised in the wind turbine, the power controller unit operating the electric generator according to a speed reference value and a power reference value, the speed reference value and the power reference value being chosen along a linear operating trajectory in a power vs speed graph, the linear operating trajectory including a point corresponding to the nominal power and the nominal generator speed, wherein the power controller unit includes a slider command for selecting an angular position of the linear operating trajectory in the power vs speed graph,
wherein the linear operating trajectory is movable in the power vs speed graph between a vertical operating trajectory and an inclined operating trajectory, an angle being provided between the vertical operating trajectory and the inclined operating trajectory, the value of the angle being selectable through the slider command of the power controller unit between 0° and 90°.
