Abstract: A nacelle for a wind turbine and a method for erecting a wind turbine are disclosed. The nacelle comprises a main unit arranged to be connected to a wind turbine tower, via a yawing arrangement, and at least one side unit mounted along a side of the main unit in such a manner that direct access is allowed between the main unit and the side unit(s), each side unit accommodating at least one wind turbine component, and at least one side unit being capable of carrying the wind turbine component(s) accommodated therein. The main unit and at least one of the side unit(s) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine. A sufficient interior space of the nacelle is obtained while allowing the nacelle to be transported due to the modular construction. The weight of the wind turbine components is arranged close to the tower due to the transversal arrangement of the side unit(s) relative to the main unit.

Abstract: A method of charging an energy storage system, such as a battery, a capacitor, or a super capacitor, using a wind turbine is described. The method comprises establishing if turbine power production can be increased and establishing if the energy storage system is capable of taking a charge. If both conditions are met, the power generated by the wind turbine is increased above a rated power of the wind turbine and the additional power is used to charge the energy storage systems. A method of control is also disclosed.

Abstract: A method of forming a wind turbine blade shear web flange section (36) by resin transfer moulding comprises providing a mould assembly (84) comprising a mould surface (86) defining a mould cavity and arranging a plurality of elongate flange elements (46) with the mould surface in an array (80) such that the flange elements are positioned one on top of another with first and second longitudinal ends (56,60) of each flange element longitudinally offset from respective first and second longitudinal ends of a neighbouring flange element so as to form a tapered portion (58,62) at each of a first and second longitudinal end of the flange section (36). A The method further comprises injecting resin to the mould cavity and curing the array of flange elements in a resin matrix to form a cured flange section having a laminate construction.

Abstract: A support frame (44) and method are described herein for support of a wind turbine blade (22) on a vehicle during transport to an installation site. A load indicator (46) is provided adjacent one or more support pads (52) when using the support frame (44), with the load indicator (46) being configured to determine and communicate an amount of movement of the wind turbine blade (22) relative to the support frame (44) during initial loading into the support frame (44) and during transport. To this end, the load indicator (46) helps assure that the wind turbine blade (22) is properly loaded into the support frame (44) in a desired transport position, while also confirming whether significant shocks or other movements have occurred during transport that could lead to a higher likelihood of internal or external damage at the blade (22).

Abstract: A method of lifting a rotor of a wind turbine, the rotor having a center of gravity and including a hub and first, second, and third blades projecting outwardly from the hub at locations circumferentially distributed thereabout, includes positioning first and second slings around the first and second blades, respectively, to define first and second lifting zones delineating a lifting envelope, wherein the lifting envelope encompasses the center of gravity. The method also includes lifting the rotor above a surface via the first and second slings wherein the rotor is in one of a substantially horizontal or substantially vertical orientation, with the aid of at least one of the first and second slings while continuing to fully support the rotor by the first and second slings.

Abstract: Calculating a wind speed associated with a return period at a proposed wind turbine site. The method comprises selecting a first set of storms from wind speed measurements measured at the proposed site, and selecting a second set of storms from modelled wind speeds, the modelled wind speeds being estimates of wind speeds at the proposed wind turbine site during the measurement period from a mesoscale data set. A comparison is made of characteristic wind speeds of the first and second sets of storms to determine a correction factor. A third set of storms is selected from an extended set of modelled wind speeds from an extended mesoscale data set, and the correction factor is applied to characteristic wind speeds of the third set of storms to provide corrected wind speeds. A wind speed associated with the return period is calculated from the corrected characteristic wind speeds.
