Highway-Distributed Solar and Wind-Solar Hybrid Power Supply Solution

Intelligent Transportation Systems are built upon advanced traffic information systems, integrating Information Collection Technology The effective integration of data communication technologies, automated control systems, and computer processing techniques into the overall transportation management framework enables seamless coordination and harmonious collaboration among people, vehicles, and roads. This, in turn, fosters the establishment of a comprehensive, real-time, accurate, and highly efficient transportation management system that operates effectively across a wide range of applications.

The three major electromechanical systems for intelligent highway engineering, along with the tunnel electromechanical system, include: Monitoring System (Toll stations and Road Monitoring ), charging system, communication system ； "The tunnel electromechanical system" typically includes the tunnel monitoring system, tunnel lighting system, tunnel power distribution system, and Tunnel Fire Alarm System Several major categories 。

The highway power supply system is characterized by its ribbon-like distribution, long distances, and low power output—features that perfectly align with the characteristics of distributed power sources. Distributed power systems typically integrate multiple energy sources, such as solar power generation, wind-solar hybrid systems, and energy storage solutions, enabling decentralized installation with centralized management. This approach not only reduces investment and operational costs but also enhances flexibility and efficiency in power delivery.

Solar-powered tunnel lighting case study:

According to national standards 400 Highway tunnels exceeding 10 meters in length must be equipped with lighting facilities. Typically, according to current standards, the tunnel is divided into four design sections: the entrance section, transition sections, the middle section, and the exit section. Notably, there are two transition sections—each strategically placed before and after the middle section. The length and illumination levels of each section are determined based on year-round driving safety requirements. Specifically, the maximum interior illumination level is calculated by considering both the highest external brightness throughout the year and the maximum vehicle speed, which in turn dictates the appropriate wattage and light fixture distribution density for each segment within the tunnel.

The Lipei Expressway's Majiawan Tunnel lighting solar power system, designed and constructed by Hepuyu New Energy, is the first to utilize a photovoltaic power supply solution. The Majiawan Tunnel consists of separate left and right bores, with a total length of 800 Rice, total lighting power 15KW Total installed capacity of solar power 20KWp , capable of meeting the lighting and electricity needs for about two caves each day. The solar photovoltaic power generation system combines a solar low-magnification concentrating system with a conventional crystalline silicon photovoltaic system. Through multiple pathways MPPT The charge controller charges the storage battery, and the inverter converts DC power into AC power. 380VAC To power the tunnel lighting fixtures.
