摘要： A wind turbine generator, an active damping method thereof, and a windmill tower in which vibrations of the wind turbine generator itself or the windmill tower can be reduced at low cost are provided. The acceleration due to vibrations of a nacelle is detected with an accelerometer attached to the nacelle. In an active damping unit, a pitch angle of windmill blades for generating a thrust on the windmill blades so as to cancel out the vibrations of the nacelle is calculated on the basis of the acceleration, and the pitch angle is output as a blade-pitch-angle command δθ* for damping. On the other hand, in a pitch-angle control unit, a pitch angle of the windmill blades for controlling the output to be a predetermined value is calculated, and the pitch angle is output as a blade-pitch-angle command θ* for output control. The blade-pitch-angle command δθ* for damping is combined with the blade-pitch-angle command θ* for output control using a subtracter. The pitch angle of the windmill blades is controlled on the basis of the resulting blade-pitch-angle command after combining.

摘要： It is intended to provide a power generating apparatus of renewable energy type and an operation method of the power generating apparatus, which can achieve both variable speed operation and grid connection without a frequency converting circuit and which uses a hydraulic transmission. In the power generating apparatus of renewable energy type 1, renewable energy received via a blade 4 is transmitted to a synchronous generator 20 via a rotating shaft 8 and a hydraulic transmission 10. The synchronous generator 20 is driven by a hydraulic motor 14 of the hydraulic transmission 10 to generate power. The synchronous generator 20 is connected to a grid without a frequency converting circuit and the power generated by the synchronous generator 20 is supplied to the grid 50. The power generating apparatus 1 is also provided with a transmission controller 40 which controls the hydraulic transmission 10. The transmission controller 40 controls the hydraulic transmission 10 in a normal operation mode to adjust displacement of each of a hydraulic pump 12 and the hydraulic motor 14 such that the rotating shaft 8 rotates at a rotational speed that is variable with respect to flow speed of the renewable energy while keeping a rotational speed of the synchronous generator 20 at a synchronous speed based on frequency of the grid 50 during normal operation of the power generating apparatus.

摘要： When a rotor is suddenly accelerated, a wind turbine generator is stopped without exerting a mechanical impact on both a tower and wind turbine blades. When the rotational speed of a wind turbine rotor is suddenly accelerated, a control unit controls the driving speed of the blades so as to change from high speed to low speed, stepwise or continuously, when a pitch-angle control unit drives the pitch angle of the blades to a feathering side.
