Scope

Scope: This document specifies the basic requirements for traction power supply projects of dual-mode rail transit, including traction power supply, traction substations, traction networks, power monitoring, and interface design. This document applies to the design of traction power supply for new and renovated projects of dual-mode rail transit with a nominal AC voltage of 25kV and an operating speed of no more than 200km/h, as well as a nominal DC voltage of 1500V and an operating speed of no more than 120km/h. Main technical content: With the rapid development of China's economy, the demand for interconnectivity between urban and suburban rail lines is increasing. The dual-mode traction power supply method has the advantage of breaking down barriers between different power supply systems and enabling interoperability between urban and suburban rail transit. This document specifies the basic requirements for traction power supply projects of dual-mode rail transit, including traction power supply, traction substations, traction networks, power monitoring, and interface design. As the first design specification in China for dual-mode traction power supply technology, it plays a significant role in standardizing the design principles and technical requirements of dual-mode traction power supply and will promote the application of dual-mode traction power supply projects.
