摘要
送电线路的设计风速,是确定线路塔型、塔材设计的一个重要参数,对线路的工程造价和安全运行等起到重要的作用。根据我区沿海防城港电厂—久隆变500 kV线路的特点,经过对大风成因分析、微地形、微气候调查、风速取值分区等途径分析确定最大设计风速。
Wind speed design for power transmission line is important for determination of tower type and mate- rial, and affects construction cost and safe operation of the line. Maximum wind speed is determined for 500kV transmission line from Fangchenggang Power Plant to Jiulong Substation in light of its characteristics based on gale cause analysis, survey of microrelief and microclimate, and division on value taking for wind speed.
