A yawing system for a wind turbine comprising a tower construction and a nacelle. The yawing system comprises a stationary part being connectable to or forming part of a tower construction of a wind turbine, and a rotating part being connectable to a nacelle of a wind turbine. The rotating part is arranged adjacent to the stationary part in such a manner that the rotating part is allowed to rotate relatively to the stationary part via a gear connection between the stationary part and the rotating part. The rotating part comprises a plurality of modules, each comprising a sub-module, the sub-modules being at least substantially identical in size and shape. Each module is configurable to perform various functions, e.g. by positioning one or more function defining elements in the corresponding sub-module. Thereby a configured module belongs to a category of modules reflecting the function of the configured module. At least one of the modules is configured as a drive module adapted to drive a rotational movement of the rotational part relatively to the stationary part, via the gear connection. Due to the similarity in size and shape of the sub-modules, a module belonging to a category may be replaced or reconfigured to belong to a different category of modules without altering the main design of the rotating part. Thereby a highly customizable yawing system is obtained, which can be produced in a cost effective manner. |
