A few days ago, it was learned from Guangxi Yingli Yuansheng Construction Engineering Co., Ltd. (hereinafter referred to as "Yingli Yuansheng Construction Engineering"), a subsidiary of Yingli Group, that the "photovoltaic + railway" demonstration project undertaken by it was completed and connected to the grid.

According to reports, this is the first flexible support photovoltaic demonstration project in my country's railway system. It can provide 1,000 kWh of clean power to the National Railway Test Center every day, and has an important demonstration role in promoting photovoltaic clean energy in the railway field.

In recent years, photovoltaic applications have developed rapidly and are closely integrated with application scenarios such as industry and commerce, agriculture, fishery, animal husbandry, and traditional energy. In order to implement the national "14th Five-Year Plan" Comprehensive Work Plan for Energy Conservation and Emission Reduction, China National Railway Group's "14th Five-Year Plan for Railway Technology Innovation and Development", and implement the China Urban Rail Transit Association's Green Action Plan, China Academy of Railway Sciences Carry out the pilot project of "National Railway Test Center Distributed Photovoltaic Power Generation and Energy Management Test along the Railway", deploy photovoltaic + energy storage and energy management platform in the National Railway Test Center, Yingli Yuansheng Construction Engineering undertakes the distributed photovoltaic power generation test section of the Eastern Suburb Ring Road Various subsystems of the project integrate technical services such as debugging, testing, and testing.

The project is located in the eastern suburbs branch of China Academy of Railway Sciences, No. 1 Jiuxianqiao North Road, Chaoyang District, Beijing. It relies on railway slopes and sandwich plots along the line, with a total installed capacity of 216 kilowatts.

"This project is a scientific research project of the Beijing Railway Academy of Sciences, and it is also the first flexible support photovoltaic demonstration project in the railway system." Xu Hongjian, the project leader of Yingli Yuansheng Construction Engineering, introduced that, unlike the previous construction of photovoltaic power stations on the roofs of railway stations and idle vacancies, The project selects two typical plots of railway slope and sandwich land along the line, and tries to deploy a variety of photovoltaic system configuration schemes using new material brackets. Explore the path and mode of railway photovoltaic development, and the demonstration effect is outstanding.

"As an important part of transportation, the railway system has very high requirements for project safety. The PV panel installation of Yingli Yuansheng Construction Engineering adopts four modes: conventional component installation, screw pile component installation, basalt component installation and flexible bracket component installation." Xu Hongjian According to the introduction, the installation of basalt components uses MDF made of basalt to install photovoltaics, and the quality is guaranteed for 100 years; the installation of flexible bracket components is also a bold attempt. Many difficulties were solved and installed in place through rich construction experience, so as to achieve "zero error".

It is estimated that the average annual power generation of the project is 251,100 kWh, with a total power generation of 6.278 million kWh in 25 years, saving a total of 1,883.42 tons of standard coal, 5,280 tons of carbon dioxide emissions, 1.26 tons of sulfur dioxide emissions, and 1.19 tons of equivalent oxide emissions. It is of great significance to promote photovoltaic applications in a large area along the railway, develop clean energy, build a new power system, and achieve energy saving and carbon reduction.
