Abstract: A wind turbine having a wind turbine tower with a nacelle; a wind turbine rotor hub with at least one rotatably mounted wind turbine blade; a shaft coupled to the wind turbine rotor hub and a generator. The generator has a rotor having at least one superconducting rotor coil arranged rotatably relative to a stator having at least one stator coil. The rotor is arranged in a rotor housing and the stator is arranged in a stator housing, the housings being separated by a rotor-stator gap. The stator housing has a stator inner shell and a stator outer shell connected together by at least one stator housing end plate. The stator inner shell has a first inner shell element attached to a stator iron that is connected to a second inner shell element. A pressure plate is attached to the second inner shell element and the stator outer shell.

Abstract: A wind turbine and to a method for installing a generator for a wind turbine, in which a nacelle and a mainframe for installation of, e.g., a generator and a main shaft, is installed on top of a tower. The nacelle further has a nacelle cover extending over the main frame from the hub and to a rear end, covering components installed on the main frame. The nacelle cover has at least a first part and a second part, the first part having a interface for engagement with a corresponding interface on the second part, the second part of the nacelle cover housing a generator as one unit. By having the generator and the second part of the nacelle cover as a single unit, installation can be performed in one go and then only one hoist with a crane is needed.

Abstract: This invention relates to a wind turbine having an additional mass each placed between a mounting end and a free end of at least two rotor blades. This invention further relates to a method for controlling a wind turbine with a pitch system for pitching a blade in a pitch angle and with blades with a mass for increased inertia, which wind turbine is operated in a normal operation mode in which a generator has a generator speed at a generator torque, and which wind turbine is to remain electrically coupled to a grid during a low voltage condition and with supplied current specifications, torque reference, power references, or according to a grid code.

Abstract: The present invention relates to a wind turbine having a number of cables, e.g. electrical power cables, extending from a nacelle and down into a tower, where the cables are arranged in a cable loop construction, said cable loop construction comprising a number of cable spacers comprising a number of fingers extending in a radial direction at said cable spacer, thus forming a number of gaps between said fingers. By having a cable spacer comprising a number of fingers the power cables and other types of cables can be arranged more or less loose or uncoupled in a room between two such fingers. This leaves the cables free to relieve themselves from stresses when they are twisted as the nacelle is yawing in relation to the tower. Thus the cables will always be able to minimize the stresses induced by twisting, as they are not rigidly fixed to a ring or the like.
