摘要
为了分析金华市风能资源的丰匮及其分布状况,利用2017—2020年金华市8个国家地面气象观测站和169个区域自动气象站的逐小时风向风速资料,统计分析了平均风速、有效风速时数、有效风能密度等风资源评估参数。结果表明:按照风能资源区划标准,武义大莱站和义乌站的风能资源达到可利用区的标准,而其他站点则处在风能资源贫乏区,其中,大莱距地面10 m高度的年平均有效风能密度达107.5 W/m2,有效风速时数为5481.0 h,年主导风向为WNW,义乌的有效风能密度则为51.5 W/m2,有效风速时数2571.3 h,年主导风向为N;义乌平均风速的日变化幅度较大,不利于其风电在并网过程中的安全稳定。
In order to analyze the abundance and distribution of wind energy resources in Jinhua city,the hourly wind direction and wind speed data of 8 national ground meteorological stations and 169 regional automatic weather stations in Jinhua city from 2017 to 2020 were used to analyze the average wind speed,hours of effective wind speed and effective wind energy density.The results show that according to the wind energy zoning standard,the wind energy resources of Dalai and Yiwu stations are available,however,others in Jinhua city are scare.The effective wind energy density and hours of effective wind speed are 107.5 W/m2 and 5481.0 h separately in Dalai station at 10 m above the ground,and 51.5 W/m2 and 2571.3h separately in Yiwu station.The annual predominant wind direction is WNW in Dalai,and N in Yiwu.Due to the large diurnal variation of average wind speed in Yiwu,it is disadvantageous to the power system security and stability.
