风光互补供电系统在自动气象站中的应用

利用四会观测站的年均日照时数和平均风速等资料,用太阳直接辐射量和风能计算公式,求得四会市年有效太阳辐射量和风能储量分别为984.9 kWh/m2和9.1 kWh（Φ2.2 m风轮）,结合观测站和乡镇中尺度区域自动站设备的耗电情况,计算出用普通风光互补供电系统可供给本站气象仪器设备使用88天、乡镇区域气象站全年不间断使用.该发电系统既可为气象部门节省能源开支,同时也符合构建现代资源节约型和环保友好型社会的发展要求.

Application of wind-solar hybrid power supply system in automatic weather station

According to the data of annual sunshine duration and average wind speed in Sihui observation station, by means of solar radiation and wind calculation formula, the annual effective solar radiation and wind energy reserves are computed as 984. 9 kWh/m^2 and 9. 1 kWh （ 2.2 meters in diameter of wind wheel） respectively. Combined with the power consumption of observation station and mesoscale regional automatic station in township, the ordinary wind-solar hybrid power supply system can be used for supporting the operation of automatic weather station in 88 days, which can also support the operation of regional automatic station in township without a break at the same time during the whole year. This power supply system not only can save energy expenditure for the meteorological department, also be in line with the development demands of modern construction of resources saving and environmental protection society.
