In recent years, under the trend of “green and low-carbon”, the rail transit industry has continuously deepened the integration of energy and industry, and accelerated the pace of green transformation. The “Action Plan for Green Urban Rail Development of Urban Rail Transit” released in August last year has formulated six green urban rail development actions and six implementation safeguards, drawing a blueprint for the green development of the rail transit industry. This year, the National Railway Administration project “Technical Research on Achieving the goal of carbon peak in the railway industry” proposed that to promote the low-carbon transformation of transport equipment, build a green and efficient transportation system, and accelerate the construction of green transportation infrastructure as a guide, starting with the energy saving and carbon reduction of traction system and housing construction, further research on energy saving and carbon reduction technical measures in the railway industry. At present, how to further improve the energy efficiency level, improve the resource utilization rate and promote the transformation of the energy use structure of the entire industry has become an important issue that needs to be overcome in the rail transit industry.

As a practitioner and enabler of sustainable development, Schneider Electric has always worked with the urban rail transit industry to create an end-to-end green supply chain that includes green design, green procurement, green production, green delivery, and green operation and maintenance, and continues to contribute to the sustainable development of the industry through solutions based on innovative technologies. At present, Schneider Electric has provided active pre-sales support, efficient supply cooperation and professional post-production services for the rail transit construction of more than 40 cities and more than 200 lines across the country.

Three-layer architecture to help the green and low-carbon development of the industry

With the continuous expansion of the scale of the urban rail network, the total energy consumption and carbon emissions of China’s urban rail are also showing a rapid growth trend, from the planning, design, construction and operation of the whole life cycle of all links to help the low-carbon development of the industry, which is of great significance to practice the “double carbon” goal. Schneider Electric relies on the three-tier architecture and platform based on EcoStruxureTM, starting from the optimization of energy structure, green power use, energy recovery, equipment energy-saving, management energy-saving and environmental protection equipment selection, to provide all-round support for the low-carbon sustainable development of the rail transit industry.

At the product level of interconnection, Schneider Electric can provide the rail transit industry with a series of intelligent equipment, including circuit breakers and switchgear, to help the industry achieve intelligent management. Among them, the green design products represented by the air circuit breaker, through the resource recycling design, the renewable utilization rate of more than 75%, can extend the service life of the product at the same time, to help users reduce energy consumption by 55%. In addition, Schneider Electric has innovatively proposed a solution to replace sulfur hexafluoride (SF6), which has a serious greenhouse effect, as an insulating gas in environmentally friendly medium voltage switchgear, which is an important milestone to help the industry towards clean, efficient and low-carbon development.

At the edge control level, the Schneider Electric series of applications and software can effectively cooperate with the product equipment, and achieve the prediction and judgment of the equipment operating condition, and quickly judge and locate the field fault. For example, POI station control experts can quickly generate standard intelligent power distribution projects according to standard intelligent power distribution structure design to help users improve project deployment efficiency. In terms of application analysis and services, the Schneider Electric series of digital software can provide users with solution suggestions and operational guidance, helping users to move towards unattended operation and maintenance, and enjoy digital and intelligent experience.

Wei Xiangyu, industry marketing manager of Schneider Electric, said: “The transportation power, the railway first. Actively exploring the practice path of low-carbon sustainable development of the rail transit industry is of great significance for promoting the high-quality development of the industry and accelerating the construction of a transportation power. We will always uphold our mission, continue to deepen the rail transit industry, and continue to promote the deep integration of energy and rail transit industry through innovative products and full life cycle solutions, and help the green and sustainable development of the industry.”
