    摘要： A system and method are provided for determining a geographic location of a tower top pivot point (TPP) of a wind turbine tower having a nacelle (14) that includes a machine head and rotor at a top thereof. At least one rover receiver (24) of a global navigation satellite system (GNSS) is configured at a fixed position on the nacelle. A plurality of 360-degree yaw sweeps of the nacelle are conducted and the geo-location signals received by the rover receiver during the yaw sweeps are recorded. With a controller, the geo-location signals are converted into a circular plot and a radius (r) of the plot is determined, the radius being a distance between the rover receiver and the TPP. Based on a GNSS geo-location of the rover receiver and the radius, a geo-location of the TPP is computed.

    摘要： A power generation system 10 is provided. The system includes a bus, at least two converters, an energy-type energy storage unit (ES) 26, a power-type energy storage unit (PS) 27 and a controller 48. The ES and the PS are coupled in parallel to the bus through corresponding converters 44,46 of the at least two converters. The controller 48 is configured to control the ES and the PS through the corresponding converters 44,46 in at least two conditions during a charging mode and a discharging mode: when a power for the ES 26 and PS 27 is below a power threshold, control the power to flow between the ES 26 and the bus; and when the power is above the power threshold, control a part of the power to flow between the ES 26 and the bus and another part of the power to flow between the PS 27 and the bus. And a method 76 for generating power is also provided.

    摘要： A calibration apparatus 120 is configured to calibrate a magnetostrictive sensor. The magnetostrictive sensor 110 is configured to measure an object 900 and comprises a sensing element positioned adjacent to the object. The calibration apparatus comprises an estimation device 130 and a calibrator 140. The estimation device 130 is configured to estimate at least one of a gap between the sensing element and the object and a temperature of the object to obtain at least one of an estimated gap and an estimated temperature, based on geometric information, an excitation signal and an output signal of the magnetostrictive sensor, and geometric information of the object. The calibrator 140 is configured to reduce an effect on the output signal of the magnetostrictive sensor imposed by variations in the at least one of the gap and the temperature, based on the at least one of the estimated gap and the estimated temperature, to obtain a calibrated output signal.
