| 摘 要： | 为了解决目前风光互补发电系统用于道路系统路灯照明的供能不稳定性,考虑利用车辆行驶引起的空气流动转化为电能来弥补自然风能的不足,构成新的风光互补发电系统。该文基于一定的理想化假定条件,根据功能原理得到了由于车辆行驶引起的空气流速与车速的定量关系,进而分析能量的供求关系。通过对首都机场高速公路的情况进行算例分析,计算结果显示:考虑车辆行驶引起的空气流动的能量的情况下,首都机场高速公路的照明能源完全可以依靠新型风光互补发电系统提供。

| Abstract: | Existing Wind-Solar Energy Hybrid Generation Systems for road lighting systems sometimes can out of power.This study takes advantage of the wind energy caused by the moving vehicles to make up for the shortage of natural wind.The work-energy principle is used to develop a quantitative relationship between the air velocity caused by the moving vehicles and the vehicle speed.An energy supply example is given based on the Beijing Capital Airport Expressway shows that energy from the hybrid systems from the air flow caused by the moving vehicles is sufficient for the lights. |
