現状の3 枚翼水平軸型風車技術をベースとした更なる風車の大型化の効果と課題を抽出するため、ロータ技術、ドライブトレイン技術、風力発電のCOE(Cost of Energy) 、ロジスティクス、O&M に関する文献を広く収集・整理し、次年度以降の本格的な調査研究のための情報整理を行った。更に、10MW 超級風車に関する予備調査として、2014 年3 月10 日から13 日、スペイン・バルセロナにおいて開催されたヨーロッパ風力エネルギー協会主催年会・展示会(European Wind Energy Association 2014 Annual Event) に参加し、この分野で先行するヨーロッパにおける最新の研究開発動向について調査した。先端的ロータ技術、空力・ロータ設計、先端的ドライブトレイン技術、ドライブトレインの革新コンセプト、先端的制御コンセプト等、本調査研究に直接的に関連するセッションにおいて、当該調査研究分野におけるヨーロッパの先行研究についての情報を入手した。展示会ブースにおいては、関連企業との情報交換を行い、次年度に予定している本格海外調査先の開拓を行った。
英文要約Title : Advanced Practical Research and Development of Wind Power Generation / Advanced Practical Development of Wind Turbine Components / Research on Over 10 MW Class Wind Turbines (Elemental Technologies) (FY2013-2014) FY2013 Annual Report

In order to extract the effects and problems of upscaling based on the current three bladed horizontal wind turbine, technical literature that relates rotor technologies, drive train technologies, cost of energy (COE), logistics, operation and maintenance (O&M) were collected widely and classified in detail. Moreover, as a preliminary investigation on over 10 MW class wind turbines, we attended the European Wind Energy Association 2014 Annual Event (EWEA2014) that was held from March 10 to 13 in Barcelona, Spain, and we studied the trend in Europe of advanced research and development. We obtained the technology information of European precedence research and development in the research sessions that relates “Advanced rotor technologies”, “Aerodynamics and rotor design”, “Advanced drive train technologies”, “Innovative concepts for drive train components”, “Advanced control concepts” and so forth. We shared information with the European companies on related themes at the exhibition booth toward the full-scale investigation that was scheduled in the next fiscal year. In order to evaluate the feasibility of two bladed rotor that was treated as the next generation new technology aiming further reduction of generation cost, the wind tunnel model testing for aerodynamic characteristics analysis and the model testing for behavior analysis will be simultaneously conducted in this study, and the specification of the two testings were examined. For the next fiscal year’s testings, the conditions and parameters of the two testings were determined, and the configuration and specification of the testing apparatus were decided to attain those testing conditions and parameters. The geometrical shape of rotors for two testings is equalized in order to equalize the aerodynamic characteristics of rotor models between two testings, and the shape of rotor models was designed to properly actuate at the Reynolds number of 400,000 and the tip speed ratio of 8. For the aerodynamic characteristics testings, the testing apparatus was designed so that testing with both two bladed and the three bladed rotor configuration and with both upwind and downwind rotor configuration can be attained in order to study the effects and problems of two bladed wind turbines. For the behavior testings, the configuration and specification of whole experimental system that will be combined with Hardware In the Loop Simulation (HILS) technology were determined. The CFD (Computational Fluid Dynamics) simulations with special scale of both wind tunnel model testing and over 10 MW full-scale wind turbine operations will be conducted to evaluate the performance improvement and the effects to mechanical load by the two bladed rotor in detail from the detailed information that can not be obtained by the model testings, and the condition and specification of CFD simulations such as resolution of computational grid were considered and determined.
