摘要： A method for feeding electric power into an electric supply network by means of a wind park comprising several wind turbines. The method comprises the steps of feeding the electric power at a network connection point, recording at least one network state parameter at the network connection point by means of a park control unit, checking the supply network for the presence of a transient process and sending, and/or sending at an increased clock rate, the values measured by the park control unit and/or the control values determined by the park control unit to the wind turbines, once the presence of a transient process has been detected.

摘要： A wind turbine is controlled in response to an estimate of vertical and/or horizontal wind shear. A tilt moment is estimated from flapwise and edgewise blade bending moments, azimuth and blade pitch positions and used to estimate vertical wind shear. A yaw moment is also estimated from flapwise and edgewise blade bending moments, azimuth and pitch position and used to estimate horizontal wind shear. A tip speed ratio is determined from an estimate of wind velocity over the rotor plane and is used to set a blade pitch angle which is passed to a blade pitch controller. The pitching may be collective or individual. In the latter case, the tip speed ratio is determined from a plurality of rotor plane positions to derive a cyclic pitch reference for each blade.

摘要： The present invention relates to a control system for thrust-limiting of wind turbines, which wind turbine comprises at least one tower, which tower carries at least one nacelle which nacelle comprises a rotating shaft, which shaft is rotated by one or more blades, which blades at pitch regulated by a pitch control system. It is the object of the present invention to reduce mechanical load and stress of a wind turbine. A further object is to reduce the maximal load on tower of a wind turbine. The thrust-limiting control system performs control of the pitch angle, which thrust-limiting control system performs regulation of the pitch angle based on at least a first input from a wind estimator and a second input from a turbulence estimator. By thrust-limiting control, reduction in the maximum mechanical load on a tower, or maybe also a nacelle, can be achieved by a relatively high percentage of the load in a way where it has only very limited influence on the power production of the wind turbine.
