Abstract

The invention provides a floating draught fan platform wave absorbing and roll stabilization power generation device and an active control method thereof. The floating draught fan platform wave absorbing and roll stabilization power generation device comprises three platform pile legs and supporting rods for being connected with the platform pile legs; a wave absorbing floater is arranged inside each platform pile leg, the upper end of each wave absorbing floater is provided with a stepping motor, a linear power generator rotor is connected to the output end of each stepping motor, and the lower end of each linear power generator rotor is provided with a thread; a buffer spring is matched with each thread of the corresponding linear power generator rotor through a thread seat, and the upper end of each buffer spring is connected with the inner top of the corresponding platform pile leg; the upper end of each platform pile leg is provided with the corresponding linear power generator rotor, and the upper ends of the linear power generator rotors sequentially penetrate through the buffer springs, the platform pile legs and linear power generator stators; and the outer surface of each platform pile leg is further provided with a bracket, and each bracket is provided with an incoming wave signal collecting device and an incoming wave signal processing device. The floating draught fan platform wave absorbing and roll stabilization power generation device can stay in the best wave absorbing and roll stabilization position all the time, and the efficiency of the wave absorbing and roll stabilization power generation device is greatly improved.

Description

technical field [0001] The invention relates to a wave-absorbing and anti-rolling power generation device for a floating fan platform and an active control method thereof, belonging to the fields of ships and marine engineering and automatic control. Background technique [0002] With the increasing maturity of offshore wind power technology, it has become an inevitable trend for the wind power industry to develop offshore. Compared with onshore wind energy, offshore wind energy has abundant reserves, high wind speed, long average annual utilization hours, little impact on human life, and is close to the coastal power consumption concentration area. At present, the development of offshore wind power is mainly concentrated in shallow seas, using fixed support platforms. As the water depth increases, the wind speed will be greater and the wind shear will be smaller. Therefore, the development of offshore wind power in the future will inevitably go to deep sea. [0003] As the...

Problems solved by technology

Since the floating support platform has no stable pile foundation, the motion response under the action of wind and waves is relatively large, which seriously affects the working efficiency and safety of the wind turbine. How to reduce the motion response of the floating support platform under the action of waves and wind The key technology of fan

[0004] In the field of offshore wind energy development and utilization, there are two types of wind turbines: fixed and floating. Fixed wind turbines are generally used in sea areas with water depths below 30-50m. Because their pile foundations are fixed on the seabed, they are similar to land-based wind turbines. There are not many technical difficulties in application, but floating wind turbines have many technical challenges in application due to the lack of a stable foundation. This is also the main reason for the slow development and utilization of offshore wind energy.
