摘　　要：在WSN节点太阳能光伏自供电系统中,光伏电池板的部署角度是影响获取太阳辐射量的重要因素之一。阐述了光伏电池板固定过程中的倾斜角度和方位角度,给出了倾斜角和方位角的最佳角度部署策略。在此基础上,以桂林某大学(E110.3°,N25.07°)为部署实验地点,利用PVsyst 6软件对光伏电池板最佳倾斜角和方位角的部署策略进行了仿真实验。结果表明,在该实验地点,最佳倾斜角度为20°,最佳方位角度为偏正东方向-1°~偏正西方向4°。同时,通过Meteonorm软件,以NASA提供的桂林市太阳能光照辐射量数据为例,对最佳角度部署模式(倾斜角度取20°,方位角度取1°)和水平面部署模式进行了对比实验,结果表明,从年度光照总辐射量来看,相对于水平面部署模式,本文提出的最佳角度部署模式能获取更多的能量,稳定性更好,性能更优越。In the WSN node solar photovoltaic self-powered system,the deployment angle of photovoltaic panels is one of the important factors affecting the amount of solar energy acquired.The paper defines the tilt angle and azi-muth angle in the fixing process of photovoltaic panels,presents the optimal angle deployment strategy for tilt an-gle and azimuth angle.The experimental site is located in an university of Guilin(east longitude 110.3°and north latitude 25.07°).By PVsyst 6 software the deployment strategy of optimal tilt angle and azimuth angle of photovol-taic panels are simulated.The simulation results show that the optimum tilt angle 20°,and the optimum azimuth angle-1°to 4°from due east to due west.With Meteonorm software,and the solar radiation data of Guilin city provided by NASA,the optimal angle deployment mode(tilt angle 20°,azimuth angle 1°)is compared with the horizontal plane deployment mode.The experimental results show that compared with the horizontal deployment mode,the optimal angular deployment mode can obtain more energy and better stability from the perspective of the total amount of annual light radiation.
