Abstract: An electric generator for a wind turbine is provided including a stator or rotor, the stator or rotor having plurality of winding systems, each winding system covering a respective angular portion of the stator or rotor about an axis of rotation of the electric generator, and a controller for controlling the current flowing in the winding systems. The controller is configured for receiving or determining a thickness of an airgap between the stator and the rotor and controlling the current flowing in at least one of the winding systems so that a respective magnetic radial force is generated, the magnetic radial force acting on the stator and/or rotor for increasing the airgap where the airgap is below a threshold airgap value.

Abstract: A stator segment of a stator of a generator for a wind turbine is provided. The stator segment includes a base body extending between a first axial end and a second axial end in axial direction and in circumferential direction of the generator, wherein the base body includes a circumferential end face extending between the first axial end and the second axial end. Furthermore, an end tooth structure extends in radial direction from the base body and extends between the first axial end and the second axial end, wherein the end tooth structure spaced apart from the end face along the circumferential direction for forming an accommodation space for accommodating an end coil of the stator. The stator segment further includes a spacer structure for being coupled to a circumferentially arranged adjacent stator segment for spacing the accommodation space from an adjacent accommodation space of the adjacent stator segment.

Abstract: A method for determining improved control parameters of a number of wind turbines of a wind park is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The method includes the steps of: receiving, by an interface, one or more actual manufacturing tolerances of characteristic values for each of the number of wind turbines; determining, by a processing unit, for each of the number of wind turbines a power versus wind speed map which is calculated from a given turbine model with the one or more actual manufacturing tolerances of the respective wind turbines as input parameters; and deriving, by the processing unit, the control parameters for each of the number of wind turbines from their associated power versus wind speed map.

Abstract: A method for determining control parameters of a turbine by consideration of component-relevant temperature limits is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance in a turbine model to determine control parameters for the turbine without damaging it. The method includes the steps of: receiving, by an interface, one or more measurement values of turbine sensors; determining, by a processing unit, at components or turbine places being equipped or not with turbine sensors, one or more virtual parameters and/or temperatures by a simulation of the operation of the turbine, the simulation being made with a given turbine model in which the one or more measurement values and one or more characteristic values of the wind turbine are used as input parameters; and deriving, by the processing unit, the control parameters for the wind turbine from the one or more virtual parameters and/or temperatures.
