摘要: 本文选取322个气象台站(自记158个,非自记174个)10年(1971—1980)风速资料统计计算了3.5—20.4m/s有效风速出现的小时数,年(月)风能和风能密度,风速、风能变化规律;绘制了年有效风能和有效风速频率分布图,进而按风能资源分布规律做出风能区划及风能的高度变化。其次,结合实际风能资料,阐明风能与风力机输出能量转换关系,从而测算出该地区农田灌溉和风力发电的风能资源利用转换值。最后,根据当地实际风能资源、环境、地形及地下水位高低,为选择合理的设计风速或引进适合当地的风力机以及解决当地部分能源提供合理化建议和对该区发展风力机的前景提出了看法。实践证明具有一定的实际应用价值。

Abstract: On the basis of 1971-1980 wind speed data from 332 weather stations (158 of them are automatic recorders), calculations are made on the number of hours of the effective wind speed (3.5-20.4ms-1), the annual and monthly amount of wind energy, and the change regularities of the wind speed and the wind energy. Distribution maps are drawn for the annual effective wind energy and effective wind speed frequncy. according to these maps the regionalization of wind energy and its variation with height are proposed.Using the practical data about the wind energy, the relation between the wind energy and the energy output through a wind machine is explored, and there upon the value of the utilization of the wind energy resource is found out for irrigation and electricity generation in given areas.According to the conditions of the wind energy resource, environment, topography and underground water level, proposals are made on the proper choice of design wind speed to set up a network of wind machines to provide energy for local use. The prospects are found encouraging.Since the results presented have been verified with satisfaction, the paper may serve as a better reference for authories concerned to plan their work.
