和文要約
英文要約 Over 10MW Class Wind Turbine systems are being studied by many organization for the middle and the future technology. In this project, it is investigated, categorized about development items and evaluated it’s feasibility.
(1)Design Conditions: The market volume for this turbine is assumed minimum 400 units for 10 years at a start point. During 2014 and 2023, total installed units are expected below.3-6MW: about 6500 units,6-10MW: about 2400 units,10MW-: about 180 units For acquiring 400 units volume described before, the market include 6-10MW region. Considering cyclone condition, the extreme wind condition is decided 57.5m/s at 10 minutes average value. The mean wind condition is decided IEC I-B for this offshore condition.
(2)Concept study: The comparison of the generator systems and the comparison of the power train systems are done and the specifications of 10MW wind turbine of this conceptual design is followings.
Rated power:10MW,Rotor Diameter:204m*,Rotor Position: Down Wind, Hub Height: 130m*,Tower Base Height: 20m*,Blade Length: 100m,Base Type: Jacket, Tip Speed Ratio: 9.0,10.0,11.0,Rotor Speed: 4.0-8.5min-1*,Tower Head Mass: 750ton*,Tower Mass: 660t*,*:Interim value
The single pass geared PMG(Permanent magnet generator) and RCG(Rotary Converter Generation system) or the multipass geared PMG and RCG will be investigated next year.
(3) Conceptual design: Based on Concept study, Conceptual design is proceeded. Feasibility including economical aspect is investigated. In this year the blades, the tower and the base are determined as aero-elastic models. The performance, the vibration, the deformation and the load are calculated. The power curve is also calculated.
(4)Blade conceptual design: The blade geometry is decide for bearing the extreme wind condition. In next year the dynamic behavior will be investigated. The materials of blades are CFRP for spar cap and GFRP for the others.
(5)Feasibility study of next generation power train: The power train concepts selected in this year will be designed conceptually next year. The conceptual designs are consists of the specification, the cost, the installation and the maintenance.
(6)Power up study based on the component study: The economical improvement of 10MW wind turbine will be investigated. 20MW wind turbine will be also investigated based on the component study of 10MW wind turbine.
