Abstract: | With the background of offshore wind energy projects,this paper studies aerodynamic performance and geometric characteristics of large capacity wind turbine rotors(1 to 10 MW) ,and the main characteristic parameters such as the rated wind speed,blade tip speed,and rotor solidity. We show that the essential criterion of a highperformance wind turbine is a highest possible annual usable energy pattern factor and a smallest possible dimension,capturing the maximum wind energy and producing the maximum annual p... |
