专利汇可以提供WIND POWER PLANT WITH AN AUXILIARY POWER DEVICE FOR MOVING ROTOR BLADES IN A FAULT SCENARIO专利检索,专利查询,专利分析的服务。并且The invention relates to a wind power plant, comprising means for moving the rotor blades (RB) about the longitudinal axis (LA). Said means have at least one actuator (SA) with a control motor (SM) for moving at least one rotor blade (RB), at least one auxiliary generator (HG) for supplying electrical energy from the kinetic energy of the rotor shaft (RW), a fault detection device (SI) which is active in a fault scenario (FF), and a switching-over device (US). When activated, said switching-over device conducts the electrical energy of the auxiliary generator to at least one control motor, in order to move at least one rotor blade into a flag position (FS). Associated with this is the advantage that low-wear, low-maintenance control motors can be used without a static auxiliary energy device.,下面是WIND POWER PLANT WITH AN AUXILIARY POWER DEVICE FOR MOVING ROTOR BLADES IN A FAULT SCENARIO专利的具体信息内容。
