高速公路特殊位置节能照明控制系统设计——阳光和风能

Highway Special Position En-ergy-Saving Lighting Control System Design—The Sun and Wind

摘要: 高速公路中隧道、立交等特殊位置需要照明。伴随着我国高速公路建设的快速发展，这些特殊位置的数量和里程数也在不断的增加，产生了巨大的照明用电需求和费用，给高速公路运营带来了极大的困难。如何结合高速公路特征，设计自服务照明控制系统，提升高速公路照明用电自给自足能力是关键。针对这一问题，设计了一种高速公路特殊位置节能照明控制系统，利用高速行驶车辆带来的风能和改进的垂直轴风力涡轮发电装置，实现了狭小空间约束下不受天气约束的风力发电，提升高速公路照明自给自足能力。系统与普通照明供电系统结合，并根据应用场景，辅以光伏发电，既进一步提升了高速公路自服务功能，又保障了照明系统各种条件下的不间断工作。设计的系统具有实现简单、成本低、占用空间小和节能效果显著的特点。以高速公路隧道为例，本项目预计节约隧道照明电费35.2亿元/年。本项目社会效益良好，极具推广价值。

Abstract: Highway tunnels, interchanges and other special locations need lighting. With the rapid development of highway construction, the number and mileage of these special locations are also increasing, resulting in the huge electric demand and cost of lighting, which brings great difficulties to highway operation. How to design the self-serving lighting control system based on the characteristics of the highway and improve the self-sufficiency of the highway lighting power supply is the key. To solve this problem, an ener-gy-saving lighting control system for special locations of expressways is designed. By using the wind energy brought by high-speed vehicles and the improved vertical axis wind turbine power genera-tion device, wind power generation free from weather constraints in narrow space is realized, and the self-sufficiency of expressways lighting is improved. The system is combined with the general lighting power supply system, supplemented by photovoltaic power generation according to the application scenarios, which not only further improves the self-serving function of the highway, but also ensures the uninterrupted work of the lighting system under various conditions. The designed system has the characteristics of simple implementation, low cost, small occupancy space and re-markable energy-saving effect. Taking the expressway tunnel as an example, the project is esti-mated to save 3.52 billion yuan per year in tunnel lighting electricity charges. This project has good social benefits and great promotion value.
