摘要： A sensor system for measuring an operating parameter of a wind turbine component is described. The fiber optic sensor system comprises a light source for outputting light in a predetermined range of wavelengths, and an optical fiber comprising a long Fiber Bragg Grating, extending continuously over a length of the optical fiber to provide a continuous measurement region in the optical fiber. The optical fiber is coupled to the wind turbine component such that the continuous measurement region is located at a region of the wind turbine component to be sensed, and such that the grating period at each location in the continuous measurement period is dependent upon the value of the operating parameter at that location. A light detector receives light from the optical fiber, and provides an output signal to the controller indicating the intensity of the received light; based on the detected light, a value for the operating parameter is determined.

摘要： A connector for providing a high current connection between printed circuit boards. The connector comprises a fastener, an electrically conductive spacer, and a nut. The fastener extends through a through-hole in each of the printed circuit boards. The spacer is disposed about the fastener and between the printed circuit boards. The nut engages a distal end of the fastener and forces the spacer into electrical contact with electrically conductive pads that at least partially surround each of the through-holes on sides of the printed circuit board that face one another. The nut may be press fit or otherwise captivated, or formed integrally in one of the printed circuit boards such that the electrical connection may be effected from a single direction. The spacer may be optimized for electrical conduction while the fastener and/or nut may be optimized for strength, rigidity, low cost, or a combination of such factors.

摘要： A wind turbine comprising a nacelle (1) is disclosed. The nacelle (1) accommodates at least a generator (3) and power electronics electrically interconnected between the generator (3) and a power grid. At least one power electronic component (10, 11, 12) is removably arranged in the nacelle (1) in a region positioned between a floor level of the nacelle (1) and a lower limiting surface, e.g. a bottom wall, of the nacelle (1). The space available in the interior parts of the nacelle (1) is thereby utilised to a greater extent than in prior art wind turbines, and replacement of a power electronic component (10, 11, 12) can be performed using ordinary lifting equipment. Furthermore, the risk of injury to maintenance personnel is reduced.

摘要： A wind turbine is arranged to operate in a fully-functional converter mode and a faulty-converter mode. A plurality of converters are arranged to share electric current in the fully-functional converter mode. The converters are dimensioned not only to operate at nominal active current but to provide an over-current margin to enable reactive current to be produced on top of the nominal active current in the fully-functional converter mode. In the fully-functional converter mode the converters are caused to produce reactive current on top of the nominal active current. In response to a fault of one or more of the converters, operation is changed from the fully-functional converter mode to the faulty-converter mode. In the faulty-converter mode, one or more other converters of the converter system are caused to produce additional active current by using their over-current margin to compensate at least partly for a reduction of active-current production due to the fault of one of the converters, and to reduce the reactive-current production by the other converter correspondingly.
