中文摘要: 充分考虑了额定风速对额定功率、年发电量、风轮直径, 以及机组成本的影响, 建立了相应的数学模型, 为风力发电机组额定风速的选择提供了理论依据, 并通过某工程实例进行了计算分析.结果表明:按照本方法得出的最佳额定风速为11 m/s, 与传统的额定风速确定方法得出的12 m/s相比, 尽管叶片成本提高了36.93万元, 但是年发电量增加了707 MW, 大大增加了经济效益.
Abstract:In order to solve the problems on the determination method for the rated speed，the effect of rated wind speed on various parameters which include the rated power，the annual generation capacity，wind turbine diameter and the cost of the wind unit are discussed.And the corresponding mathematical models are established.The optimum selection of rated wind speed for wind turbines is provided.Finally, a project study with the actual data is presented.Compared with the 12m/s calculated by traditional method, the rated speed derived in accordance with the paper is better.Though the blades cost increases by￥369300, the annual power generation increases by707MW, greatly increasing the economic benefit.
