摘要： A control system for a floating offshore wind turbine (FOWT). The FOWT includes a floating base, a tower, a nacelle, and rotor with blades that harvest energy from wind passing the FOWT. Without a rigid support, however, the FOWT is able to move. The controller uses generator speed and platform pitch position of the FOWT as inputs and manipulates blade pitch and torque resistance to achieve stability.

摘要： The present invention relates to a multirotor wind turbine comprising at least two rotor nacelle assemblies mounted to a support arrangement via respective yawing systems, and a toe angle control system for controlling the toe angles of the rotor nacelle assemblies with respect to the support arrangement; wherein the toe angle control system is configured to operate in a first mode in which the rotor nacelle assemblies are held at positive toe angles while the wind turbine is generating power in a main production mode; wherein the toe angle control system is further configured to monitor the operating mode of the wind turbine, and to switch to a second mode in which the yawing systems of the rotor nacelle assemblies are operated to reduce the toe angles of the rotor nacelle assemblies if an operating mode-based trigger condition has been met.

摘要： A method for determining at least one blade misposition of a rotor blade of a rotor of a wind power installation having multiple rotor blades with an adjustable blade angle, wherein the blade misposition describes a blade angle variance of the blade angle of the rotor blade from a reference blade angle, the wind power installation has a nacelle having the rotor and an azimuth adjustment device, wherein a circumferential rotational position of the rotor is referred to as the rotor position, and the azimuth adjustment device has at least one activable azimuth actuator in order to adjust an azimuthal position of the nacelle, comprises the steps of a detection step comprising detecting an azimuthal movement of the nacelle while the at least one azimuth actuator is inactive, and a determination step comprising determining the blade misposition on the basis of the azimuthal movement detected in the detection step.

摘要： A method of operating a wind turbine in an active idle mode is provided, the wind turbine including a rotor hub with a plurality of blades which are configured to be pitched. The method including the following steps: detecting a fault of the wind turbine; determining a number of faulty blades, whose pitching operation is faulty or affected by a fault; and operating the wind turbine in the active idle mode based on the determined number of faulty blades.

摘要： An information generating device includes a control unit for causing a motor to rotate a pinion gear meshing with a ring gear while a predetermined braking force is applied to brake rotation of a turnable part of a wind turbine, thereby causing a fastening part to deform, where the fastening part is provided to fixedly attach the motor to a target part, a deformation amount obtaining unit for obtaining an amount of deformation experienced by the fastening part, and an information generating unit for generating correlation information indicating a correspondence between a driving torque of the motor and the amount of deformation experienced when the driving torque is used to rotate the motor.
