WUHAN, China – Phase I of Wuhan Rail Transit Line 12, the longest subway loop line in Asia, officially entered service on May 1, according to a report by People’s Daily. SIFANG provided the turnkey solution for the central-level power monitoring system and substation integrated automation system, acting as the “smart power brain” to ensure safe and stable operations.

As the first line to go live on the cloud platform of Wuhan Metro’s Guobo system, Line 12 is configured for GOA4 full driverless operation – demanding higher levels of power stability, reliability and intelligence. Leveraging its mature cloudedge collaboration technology, SIFANG tailored the solution to Wuhan Metro’s activeactive dualsite architecture (“two platforms, four centers, eight network domains”), enabling seamless redundant switching between the two platforms. The system also shares data with the vehicle intelligent maintenance system, integrated supervision system and signaling system, providing robust support for fully automated train operation and smart maintenance.

SIFANG has long been a key player in the rail transit sector, having delivered full power solutions for subway lines in more than 30 Chinese cities, including Beijing, Shanghai, Guangzhou and Shenzhen. Its offerings cover central power monitoring systems, substation integrated automation systems, smart power maintenance systems, energy management systems, simulation training systems, as well as AC/DC protection devices, SVG reactive power compensators, and ring main units. The company has also achieved core technology breakthroughs – its selfdeveloped AC and DC protection devices for rail transit have both passed evaluation by authoritative institutions.
