Abstract: A method and a device for dampening movement in a multiple rotor (MR) wind turbine located at sea and comprising a tower (2) extending in an upwards direction, a load carrying structure (3, 4) forming a first section (3) and a second section (4), the first and second sections extending in different directions away from the tower (2). To provide efficient dampening of the movement, the method comprises tethering a first body (20) to the first section (3), the first body being at least partly submerged into the sea.

Abstract: Embodiments herein describe in-plane vibration damping techniques for MR turbines. The MR turbines can include arms that extend from a common tower and support multiple rotors. Because the rotors are disposed laterally away from the tower, side-to-side motion of the tower causes the rotors to have an angled trajectory that includes both lateral and vertical displacement. In addition, a rotor disposed on one side of the tower in MR turbine can have a very different trajectory than a rotor disposed on the opposite side of the tower. To account for the vertical displacement and the different trajectories, in one embodiment, a controller can use different phase offsets for each rotor when calculating pitch offsets for performing in-plane vibration damping. In another embodiment, the controller can use both the lateral and vertical accelerations of the rotors to identify the pitch offsets for the rotors to perform in-plane vibration damping.

Abstract: The invention relates to a method for controlling a wind turbine during start up, from a non-producing operation mode to a power producing operation mode when limit cycles occur during start-up. Limit cycles are detected when a number of cut-in transitions or a number of cut-out transitions are detected. A cut-in transition is when the wind turbine fails starting up despite having the wind speed or rotor speed normally required to enter a power producing operation mode. A cut-out transition is occurring when the wind turbine is falling out of power producing operation mode after having entered the power producing operation mode.

Abstract: A multiple rotor (MR) wind turbine comprising a tower (21) extending in an upwards direction, a load carrying structure (22) extending in an outwards direction and being fixed to the tower, and an energy generating unit (54) fixed to the load carrying structure, wherein the outwards direction is transverse to the upwards direction, the wind turbine further comprising a hoisting line (53) for communication of objects (52) to and from the energy generating unit (54), the hoisting line being windable from an attachment point (55) of the load carrying structure or from the energy generating unit. To allow positioning of hosted objects near the tower, or at selectable distance from the tower, the hoisting line extends from the attachment point via a suspension point (56) to a lifting point (57) where the object (52) can be attached, and the suspension point (56) is movable outside the load carrying structure.

Abstract: A system (24) and method are described herein for manufacturing a wind turbine blade (22) proximate to the final installation site of a wind turbine (10). The system (24) includes a creel (72) of feeders (74) configured to apply strengthening elements (62) onto a plurality of shell core sections (26) coupled together and fed through the creel (72). The shell core sections (26) include an external surface (56) with a plurality of external grooves (58) recessed into the external surface (56) such that the strengthening elements (62) are laid into the external grooves (58). The system (24) also includes a deposition station (78) configured to apply an outer surface material layer (82) in fluid form to cover the external surface (56) and the plurality of strengthening elements (62). A curing station (86) heats and consolidates the shell core sections (26), the strengthening elements (62), and the outer surface material layer (82) together into a final consolidated part, with the outer surface material layer (82) defining an external profile of the blade (22) following curing.

Abstract: A method for controlling a multirotor wind turbine is disclosed. A first operational state of each of the energy generating units of the wind turbine is obtained. A difference in thrust acting on at least two of the energy generating units is detected. At least one constraint parameter of the set of operational constraints is adjusted in accordance with prevailing operating conditions and in accordance with the detected difference in thrust, and a new operational state for at least one of the energy generating units is derived, based on the at least one adjusted constraint parameter, the new operational state(s) counteracting the detected difference in thrust. Finally, the wind turbine is controlled in accordance with the new operational states for the energy generating units.

Abstract: A method for controlling a wind turbine is disclosed. During full load operation, a power reference value, Pref, representing a power level to be supplied to the power grid by the wind turbine, is received, and the wind turbine is controlled in order to produce an output power which is at or near the power reference value, Pref, while maintaining a constant torque on the generator. In the case that the produced output power of the wind turbine exceeds the power reference value, Pref, excess produced energy is stored in the energy storage system, and in the case that the produced output power of the wind turbine is below the power reference value, Pref, stored energy is retrieved from the energy storage system. A power level being equal to the power reference value, Pref, is supplied to the power grid.

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.
