摘要： At least one handling device is provided having at least one floating member with first and second mutually opposite portions between which a transitional surface at least partially extends defining an interior. The device has an offshore part receiving portion therein to at least partially receive the offshore part. The floating member is simply installed in the offshore part so that it at least partially surrounds its outer surface. The offshore part thus floats on the water for being transported to an intended destination.

摘要： It comprises a rotor and a stator that they both may be formed of a single piece or they may be formed of a number of sectors. The generator further comprises at least one active module unit as an independent unit from both the rotor and the stator. The active module unit includes at least one permanent magnet, a magnet support structure attached thereto, a first attaching mechanism to removably attach the magnet support structure to the rotor or the stator, at least one coil module comprising at least one coil winding and a magnetic core, and a second attaching mechanism to removably attach the coil module to the other of the rotor or the stator. The coil module is spaced apart from the permanent magnet a predetermined distance.

摘要： Methods and arrangements for controlling the reactive power of a power generator from an initial reactive power state to a desired reactive power state are disclosed. The power generator belongs to a power farm coupled to an electrical grid. During a transition state, changes in voltage and reactive power demand are detected and control of reactive power is passed from the power farm to the power generator controller, then to a transition controller and finally back to the power farm. The power generator may be a wind turbine and the power farm a wind farm.

摘要： A method for protecting a permanent magnet generator of a wind turbine with a multiphase generator, and n number of isolated converters, the multiphase generator including a rotor carrying permanent magnets and n number of independent multiphase sub-stators comprising a plurality of windings, each converter being connected to an independent multiphase sub-stator and configured to control the plurality of windings of the multiphase sub-stator comprises determining an asymmetrical short circuit current in one of the sub-stators, which generates a first oscillating torque, disconnecting the converter linked to the sub-stator with an asymmetrically short circuited group of windings, and injecting an asymmetrical current with the remaining connected converters, wherein said injected asymmetrical current generates a second oscillating torque that is substantially opposed in phase to the first oscillating torque so that the first oscillating torque is at least partly compensated is disclosed. Permanent magnet generators are also disclosed.

摘要： Counterweight systems for a wind turbine comprising a hub mounted to a nacelle such that the hub is rotatable around a rotation axis with respect to the nacelle, the hub comprising a blade root region configured to receive a root of a blade and having a pitch system configured to rotate the blade around a pitch axis. The counterweight system comprises a beam mountable to the blade root region at a first point of the beam and a counterweight mass coupled to the beam at a second point of the beam, such that, when the beam is mounted to the blade root region, the beam is arranged substantially perpendicular to the pitch axis and the pitch system can cause the counterweight mass to rotate around the pitch axis. Methods are also provided of mounting one or more blades to a wind turbine hub by using such counterweight systems.

摘要： A method for stabilizing the rotation speed of a machine with S-characteristics is provided. The method includes calculating a target net head and a target opening to affect guide vanes of the machine, the target net head and the target opening being calculated so that the torque exerted by water flow on the turbine is null and that the machine rotates at a target rotation speed; determining a real net head to which the machine is subjected; comparing the target net head with the real net head; and adjusting the opening of the guide vanes so as to converge towards the target opening and reduce a height difference between the target net head and the real net head.

摘要： A wind turbine rotor includes a hub, a plurality of blades, and a pitch system for rotating a blade substantially along its longitudinal axis. The pitch system includes a bearing, a motor, and a gear system, wherein the gear system has a driving pinion operationally connected with the motor, an annular gear arranged to mesh with the driving pinion. Additional gear teeth are arranged to mesh with other parts of the gear system in a predefined blade position for wind speeds at or below a nominal wind speed such that upon movement from the predefined blade position, the additional gear teeth come into contact with the other parts of the gear system before the driving pinion comes into contact with the annular gear.

摘要： A locking arrangement includes at least a rotatable part, a stationary part with respect to the first part, and a locking member having locking protrusions. At least one working plane passing through the locking protrusions is defined in a locking position where compression forces are concentrated which are reaction forces to external forces tending to rotate the parts relative to each other. The parts have locking protrusions defining gaps for receiving the locking protrusions in the locking position for preventing the parts from being rotated to each other.
