光伏发电技术在高速公路中的应用研究

Application of Photovoltaic Power Generation Technology in Expressway

我国高速公路网规模大、覆盖广并处于不断发展完善阶段,高速公路日常运营需要消耗大量的电能,加之煤炭、石油等不可再生资源的逐渐枯竭,以环保和可再生为特点的太阳能开发利用得到世界各国的高度重视。本文结合中国葛洲坝集团高速公路板块的发展概况,简要介绍了中国太阳能资源的区域分布特征和光伏发电系统的组成及特点,重点阐述了光伏发电技术在高速公路中的应用发展情况,并以大广高速周家湾隧道照明和襄荆高速公路全程视频监控系统建设为例从投资效益和建设成本两方面对光伏发电技术的应用可行性进行了分析。研究成果对类似工程具有重要的参考价值。

Chinas expressway network is large-scale,wide-ranging in the region and in a stage of continuous de-velopment and improvement.In the daily operation,large amount of electric energy is needed.Due to the depletion of non-renewable resources such as coal,oil,etc.,the development and utilization of solar energy characterized by its environmental protection and regeneration has been highly valued ball countries in the world.Combined with the development situation of expressway industry of China Gezhouba Group Co.Ltd.,this paper brifly introduces the regional distribution characteristics of solar resources and the composition and characteristics of photovoltaic power generation(PVPG)systemin China and focuses on the development of PVPG technology in expressways.Taking the Zhoujiawan tunnel lighting in Daqing-Guangzhou expressway and the construction of video monitoring System in Xiangyang-Jingzhou Expressway as examples,the feasibility of PVPG is analyzed from two aspects of investment benefits and construction costs.The research results will shed light on the similar projects.
