Abstract: A vertical axis wind turbine (1) comprising a rotor (9) with rotor blades (11). The rotor rotates about a rotational axis, crosswise to an initial direction of the wind. The wind turbine has an annular, main guide face (5), having a convex shape, guiding the direction of air flow from the initial direction into an operating direction. There are one or more drainage channels (23) with a drainage channel opening (21) at one end of the drainage channel. The drainage channel opening is arranged on the convex main guide face. The turbine has a gap (19) with a gap inlet (19a) and a gap outlet (19b). The gap (19) is configured to receive air flow from the wind into the gap inlet and out of the gap outlet. The one or more drainage channels (23) have a drainage channel exit (25) arranged in the gap (19).

Abstract: There is provided methods (100, 200) and systems for controlling a multi-rotor wind turbine generator (1) having at least two rotor nacelle assemblies (3) mounted to a support arrangement by a common yaw control system (9) and each having a wind direction sensor (11) mounted thereto configured to measure a wind direction relative to forward direction of its rotor nacelle assembly (3). The methods (100, 200) comprise the steps of measuring, for each rotor nacelle assembly (3), wind power parameter data over a plurality of relative wind directions, determining, based on the measured data, an optimum relative wind direction, either based on the average of two directions at which 10 the parameter is maximum or on a combined data set, and controlling the yaw system (9) accordingly.

Abstract: A method for controlling a multirotor wind turbine (1) comprising two or more energy generating units (5) is disclosed. At least one load carrying structure (3) is connected to a foundation or to a tower (2) via a yaw arrangement (4), and the load carrying structure (3) carries the at least two energy generating units (5). A requirement to a change in operation of at least a first of the energy generating units (5) is detected. Control commands for the first energy generating unit (5) and for at least a second energy generating unit (5), mounted on the same load carrying structure (3), are generated. The control commands cause the required change in operation, and the control commands cause coordinated operation of at least the first energy generating unit (5) and the second energy generating unit (5). The control commands are generated under the constraint that a yaw moment (9) of the yaw arrangement (4) is maintained below a predefined threshold level.

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: "Air movement power multiplier" is a process and device that uses artificially induced and channelled pressurized air movement as a power source in multiplied quantities relative to initial energy. The air is channelled through the pipe-channel of the projected length and diameter, by the fans, which are placed at the end, the outlet, of the pipe-channel, or inside the pipe-channel in the closed system. A number of converters of the straight-line movement of mechanical energy into the rotary movement are mounted on the shaft passing through the centre of the pipe-channel, and this energy is converted into electrical energy by the electric generator, in multiplied quantities relative to the initial energy.
