Abstract:
A method for constructing an offshore wind turbine includes: attaching all or a part of electrical products to a tower on land; stowing, on a work platform, the tower to which the electrical product is attached; and disposing, on a foundation, the tower, to which the electric product is attached, by using a crane of the work platform in the sea. In addition, the electrical products are classified into special high-voltage devices and the other electrical products, the special high-voltage devices are modularized on land, the other electrical products are attached to the tower on land, and the modularized special high-voltage devices and the tower, to which the other electrical products are attached, are disposed on the foundation by using the crane of the work platform in the sea.
Abstract:
A wind turbine system includes blades which rotate by receiving wind, a nacelle which supports the blades and rotates with the blades, a main shaft for transmitting torque which is connected to the hub and is rotated by the rotation of the hub, and a generator which generates electricity using rotating energy of the main shaft, wherein the main shaft is connected to the hub inside the hub in the axial direction of the main shaft.
Abstract:
A downwind rotor type wind power generation device which allows a nacelle to be transported and installed more conveniently without the need for troublesome detachment and reattachment of a heat exchanger and also improves the efficiency in cooling a generator. The downwind rotor type wind power generation device includes a rotor having a hub and a plurality of blades extending radially from the hub, a nacelle having a generator for converting the rotational energy of the rotor into electric energy and a heat exchanger for exchanging heat with heat generated at least by the generator and supporting the rotor rotatably, and a tower supporting the nacelle rotatably around a vertical axis so that the rotor is positioned downwind. The heat exchanger is located on the opposite side of the rotor with respect to the vertical axis and exposed.
Abstract:
A wind power generation system according to the invention includes: blades configured to receive wind to rotate; a nacelle supporting a load from the blades; a tower supporting the nacelle; a hub supporting the blades and configured to be rotated with the blades; a rotary main shaft configured to be rotated with the rotation of the hub; a gearbox connected to the rotary main shaft and configured to increase a speed of the rotation; and a generator configured to be driven at the rotation speed increased by the gearbox. The rotary main shaft is connected directly to the hub.
