野外自动值守数据站的电源设计与应用

Design and application of automatic unattended data acquisition station power system in the field

根据野外自动值守的数据采集站的电源需求,结合当地的气象资料,给出电源系统的设计参数。针对设计参数,给出蓄电池容量的计算,考虑市场行情选取适当的蓄电池种类和规格;参考日照时数和影响因子,给出光伏发电系统的太阳能板功率原理计算,并参考地理纬度给出最佳安装角度;参考风情和影响因子,给出风力发电系统的风机功率原理计算;综合风、光参数,给出风光互补系统的太阳能板和风机功率的原理计算;同时给出三种发电方案的经济成本核算,做出最优选择。

According to the power requirement of automatic unattended data acquisition station in the field, design parameters of its power system were proposed combining with local meteorological data. Aimed at the design parameters, the capacity of battery was calculated, and the appropriate sort of battery was selected. Based on the sunshine duration and influence factors, the principle of solar panel of photovohaic power generation system was an- alyzed, and the optimum installation angle was given out considering the influence of latitude. On the basis of wind energy source and influence factors, the principle of wind power generation system was studied. The solar panel of wind and solar hybrid power generation system and its power were calculated. After comparing the application and the cost on the power supply system of three methods in the field of automatic unattended data acquisition station power system, the optimal method was selected.
