According to the present invention, a wind power generation system includes: a wind power generation apparatus including a blade that rotates by receiving wind, a main shaft that transmits rotational energy of the blade, and a generator that converts the rotational energy into electricity; and a building in which the wind power generation apparatus is installed, in which the building includes a corner portion having a chamfered shape and two wall surfaces adjacent to the corner portion, and the blade is installed in an installation region including the corner portion and a surface having each of the two wall surfaces adjacent to the corner portion.

The present invention can be included in the technical field of concrete segments for wind turbine towers and more specifically for wind turbine towers in cold climates, where ambient temperature is below 5 C. at the same time, the invention relates to a set of a concrete segment and heating means, a concrete section, a wind turbine, a mould and a method of assembling the wind turbine.

The invention relates to a method for manufacturing a connecting device for a tower-like structure, in particular an offshore wind turbine, wherein the connecting device comprises a plurality of connecting elements, in particular planar connecting elements, which are to be arranged between an upper component of the structure and a lower component of the structure when a slip joint is produced and, for the purpose of load transfer between the upper component and the lower component, are to be positioned next to one another in the peripheral direction about the longitudinal axis and/or in the longitudinal direction thereof with respect to a central longitudinal axis of the structure, wherein data relating to an actual size of the lower component and of the upper component is provided, whereupon the shape, the position and/or the condition of individual or several as well as in particular all connecting elements of the connecting device are least in part determined in a manner specific to the connecting element in order to optimise the load transfer and/or in order to compensate for any deviations of the lower component and/or of the upper component from their desired size, and the connecting elements, that have been manufactured in advance and/or subsequently, are provided for assembly on at least one of the components. The invention also relates to: a tower-like structure, in particular part of an offshore wind turbine; and a wind turbine, in particular an offshore wind turbine.

A connecting device for a tower-like structure is provided, and includes a plurality of connecting elements which are arranged between an upper component and a lower component of the structure in order to produce a slip joint, and for the purpose of load transfer between the upper component of the structure and the lower component of the structure, are to be positioned next to one another in the peripheral direction about the longitudinal axis and/or in the longitudinal direction thereof with respect to a central longitudinal axis of the structure. With respect to the longitudinal axis, the connecting device has a greater thickness in the centre thereof than at its upper and/or lower end.

A tower drum section includes: a drum section base, including two or more tower drum pieces successively distributed along its circumferential direction; and a connecting assembly. The connecting assembly includes a first connecting member and a second connecting member; the first connecting member is located inside one of the two adjacent tower drum pieces, and the second connecting member is at least partially located inside the other of the two adjacent tower drum pieces; the first connecting member includes an adapter portion and an anchoring portion. A tower includes two or more tower drum sections connected to each other. A wind turbine includes the tower. Disclosed are a mold for manufacturing the tower drum section and a method for manufacturing the tower drum section using the mold.
