Abstract: The present invention relates generally to the offshore renewable energy utilization technology. A novel floating wind-wave integrated power generation system is based on the braceless semi-submersible floating wind turbine concept and the oscillating water column (OWC) wave energy generator. The integrated system includes the offshore wind energy system and the oscillation water column wave energy system. The novel floating wind-wave integrated power generation system transfers the rise and fall movement of the water column into the air in and out movement which is converted into the electricity by the air turbine generator. This invention makes good use of pontoons at of the semi-floating platform and the mooring lines. Since the wave energy system will move with the wave movement, which will reduce the power generation efficiency. The pontoon can help to mitigate this movement. The mooring system can further prevent the movement of the wave energy device. This invention uses the braceless structure, which simplifies the construction process and reduce the fatigue issues for the braces. Compared with the traditional three columns semi-submersible wind turbine, this invention enlarges the water plane area. The moment of inertia for hydrostatic stability is enhanced, and the stability of the floating foundation is improved.

Abstract: A method for aerodynamic braking based on the independent pitch for horizontal-axis wind turbines is disclosed. The pitch angle of each blade is increased by the pitch driver installed on each blade while a wind turbine adopts pitch-to-feather braking. In accordance with the change rate of the pitch angle of each blade, the pitch angle of each blade is adjusted, respectively. Strain sensors are installed at the root of each blade, sensors used for the blade pitch measurement are installed on the inner edge of the hubs, and the pitch actuators and controllers are installed in the nacelle of the wind turbine. The respective magnitude of the tensile force is measured by the strain sensors at the roots of the three blades, and the resultant change rate is calculated. At different time instants, the pitch angle is increased to its maximum 90 degrees by using the pitch actuator.

Abstract: An active tuned mass damper applied to the offshore monopile wind turbine belongs to the field of marine technology. A mass block is connected to the inner wall of the tower through a spring. The two ends of the damper and the force actuator are connected to the mass block and the inner wall of the tower, respectively. When the installation of tower is finished, the spring and the damper begin to work. The movement of mass block will partly offset the movement of the tower caused by the wave force. The force actuator starts to work before the mating. The exact position of the nacelle can be obtained from the Global Positioning System (DGPS). The position of tower can be adjusted in the horizontal plane through the force actuator. So, the offshore installation time for nacelle will be saved. The whole installation time and cost will also be reduced.
