In recent years, urban rail transit has been widely developed in large and medium-sized cities in China. At present, 18 cities have built operation lines, and many cities have started or planned construction. According to relevant planning, the next few years will be the peak period of urban rail transit development and construction.
How to combine solar photovoltaic power generation system with urban rail transit construction and use solar energy to provide power for urban rail transit project is not only of great significance in energy saving, but also of great reference significance in guiding new rail transit project.
On August 6, the Ministry of transport issued the guiding opinions on promoting the construction of new infrastructure in the field of transportation, which mentioned building an integrated and efficient intelligent transportation infrastructure. We will guide the construction of ultra fast charging and high-power electric vehicle charging facilities in key expressway service areas such as urban agglomerations. It is encouraged to reasonably arrange photovoltaic power generation facilities along the service areas, slopes and other roads, and connect with the municipal power supply.
As the “infrastructure maniac”, a large part of the reason for its name comes from the field of transportation in China. Since the founding of new China more than 70 years ago, China has made remarkable achievements in the field of transportation. These highway facilities, railway facilities, airport facilities, etc. cover a wide area and are in a superior position. Many of them have not been fully reused, which can be described as a waste of “favorable geographical conditions”. Next, we can help you check the photovoltaic + transportation application scenarios!
Recently, with the opening of Shenzhen Metro Line 6, the application of “photovoltaic + transportation” mode has once again achieved a breakthrough. This project is an important milestone for Shenzhen Metro to achieve green transportation.
Shenzhen Metro Line 6
On August 18, Shenzhen Metro Line 6 was officially opened. It starts from the science museum and ends at Songgang. It has a total length of 49 km and 20 stations, 65% of which are elevated stations. It is the first large-scale application of distributed photovoltaic in urban rail transit elevated station in China.
According to the data collected by Neng Huanbao, Shenzhen Metro Line 6 always adheres to the goal orientation of green development, low-carbon development and circular development, strives to build a green industrial structure with high technology, high comfort, low consumption and low pollution, and strives to enhance the comprehensive strength and international competitiveness of the industry.
According to the energy-saving concept of “relying on sunshine city” put forward by Shenzhen Metro Corporation, Metro designers give full play to their creativity, make full use of the characteristics of sufficient sunshine conditions and abundant solar energy resources, and use the solar photovoltaic modules installed on the roof to convert the solar energy into electric energy to supply all low-voltage electric loads of station lighting, air conditioning, escalators and other stations Only when it can generate electricity can it be supplemented by the power supply system. Line 6 has installed photovoltaic panels on the steel roof of 12 elevated stations. According to the introduction, “the average annual power generation capacity of photovoltaic power generation system is about 2.34 million kwh, which can meet about 30% of the power and lighting demand of elevated stations. It is estimated that 58.56 million kwh of electricity can be generated within 25 years of design life, which is equivalent to replacing 23400 tons of standard coal, reducing 225900 tons of carbon dioxide, and achieving a net economic benefit of about 50.47 million yuan. “
This project is an important milestone for Shenzhen Metro to achieve green transportation and a breakthrough in the application of the new mode of “photovoltaic + transportation”. In response to the requirements of building urban green transportation and promoting the construction of ecological civilization system, with innovative rail transit solutions and project practice, the energy consumption and carbon emissions of rail transit operation are reduced, and a more intelligent and green urban experience is created.
The first photovoltaic pavement demonstration project in Fujian Province
According to the introduction, the photovoltaic pavement application demonstration project is the first photovoltaic pavement project in Fujian Province, and it is also one of the technical transformation projects of Yongtai highway development center this year. The photovoltaic road panel uses a variety of composite materials and special structural design, and has the advantages of shock absorption, good durability and high bearing capacity. The pavement with photovoltaic road panel can not only generate electricity, but also supply electricity It’s always on the road.
It is also a road surface that can generate electricity by itself, and the power generation per square day can reach about one degree. After the completion of the project, it can meet the power supply of Hexi highway service area and the charging demand of automobile and electric vehicle charging piles, and also provide technical demonstration and support for new infrastructure roads with self supplied energy in the future.
In addition to these, photovoltaic applications in life are becoming more and more common. When we walk on the road, solar street lights and photovoltaic traffic lights can be seen everywhere. Riding a Moby bike, the photovoltaic panels in the vegetable basket provide energy for the bike’s smart lock. Back in the community, looking up at the roof, you can see the figure of small family solar photovoltaic power generation
When you go out to play, you will pass by Xinjiang, Qinghai, Gansu, Inner Mongolia, Tibet and other regions of China by train or plane, and you will see the once vast desert and grassland, which has become a “blue ocean” covered by large-scale solar power generation system.
Photovoltaic power generation and green energy are changing our life step by step. With the popularization of PV + transportation, more and more people will learn about PV during their journey. As a new energy enterprise, Neng Huanbao actively responds to national policies and is committed to promoting the development of distributed photovoltaic, bringing photovoltaic power generation industry into every family, helping people who love Huanbao to create wealth and contribute to building a moderately prosperous society in an all-round way.
