    Abstract: A wind turbine blade comprising at least two wind turbine blade sections connected in a blade connection joint, where each blade section at their connection end comprises a number of corresponding dentations arranged to interconnect across the blade connection joint. One of the blade sections comprises a spar cap structure and a connecting part with a first end joined to the spar cap structure and an opposite second end positioned at the blade section connection end and comprising a number of the dentations. The connecting part further comprises a number of sheets which are interleaved with the fibre-reinforced layers of the spar cap structure in an overlapping zone thereby joining the spar cap structure and the connecting part. The invention further relates to a method for preparing a wind turbine blade section as mentioned above. The invention also relates to a method of preparing a sheet for a connecting part with a number of dentations at one end, which method involves cutting and rolling a number of unidirectional prepreg sheets to form fingers, placing in an open mould the fingers next to each other and partially apart such as to form the dentations, closing the mould, and fully or partially curing the sheet.

    Abstract: There is disclosed a method of balancing a set of first and second modular blade sections for a set of blades of a rotor of a wind turbine. The method comprises determining a mass moment of the first and second blade sections, the mass moment being determined about an axis equivalent to an axis of rotation of a hub of the turbine when the blade section is assembled onto the hub. A plurality of blade section groups 10 are defined, each comprising a first blade section of the set and at least one second blade section of the set, each blade section group having a blade section group mass moment about the axis. The first blade section and the at least one second blade section in each group are selected so as to satisfy a minimised total ballast condition, to minimise balancing ballast to be added to the set as a whole, or a minimised 15 ballasting difference condition, to minimise the difference in balancing ballast added to different blades, or both.
