  • Patent number: 10826349
    Abstract: The disclosure provides a wind turbine generator and a control method thereof. The wind turbine generator comprises at least two power transmission systems connected each other in parallel and a control system comprising an upper controller and control subsystems corresponding to the power transmission systems and comprising bottom controllers. The bottom controllers monitor operating state parameters of functional units in corresponding power transmission systems, and when determining corresponding functional units meet abnormal conditions according to operating state parameters, send operating state parameters of corresponding functional units to the upper controller; the upper controller generates operating instructions when determining faults of the corresponding functional units occur according to operating state parameters of corresponding functional units, to control power transmission systems to work according to operation instructions.

  • Patent number: 9316209
    Abstract: A movement inhibiting apparatus for a floating offshore wind turbine and a floating base with the apparatus. The movement inhibiting apparatus for the floating offshore wind turbine comprises at least one layer of an annular shake-reducing panel placed horizontally and surrounding the floating base. A plurality of shake-reducing fins is further arranged on the shake-reducing panel. The plurality of shake-reducing fins comprises a first set of shake-reducing fins arranged on one side of the shake-reducing panel and the shake-reducing fins of the first set are spaced apart vertically around the floating base. The movement inhibiting apparatus for the floating offshore wind turbine can effectively inhibit the movement of the floating wind turbine and is of low cost.
