KSTAR Power Solutions Ensure Shenzhen Metro's Ongoing Operations

The newly opened Shenzhen Metro Line 16 is located in north-eastern Shenzhen and stretches for 29.2 kilometres, connecting Longgang District with Pingshan District. It serves as an important route for revitalising the city's less-developed eastern area. According to the operator, Shenzhen Metro Group, the line uses the highest level of automation for driverless trains, GoA4, and is equipped with China's most advanced intelligent operations system, centred on traffic control, to significantly improve train dispatching efficiency.

Challenge

Developing a reliable backup power solution to protect the various metro applications on Line 16 presented several challenges. One was the dusty operating environment. Another was the complex power requirements of different loads. Communication systems, signalling systems and integrated monitoring systems, among others, require UPS units with different capacities and specifications. In addition, these loads are distributed across multiple locations, placing further demands on the day-to-day management and maintenance of backup power equipment.

Given the specific operating environment, the customer set strict requirements for product reliability. After careful consideration, the customer selected KSTAR to provide a one-stop power solution for the line, helping ensure safe and reliable operation under all power conditions.

Solutions

KSTAR developed a customised power solution comprising UPS systems, batteries and a PDC (Power Distribution Cabinet) to meet all operational load requirements. The solution is also adaptable to the diverse designs and configurations of modern metro systems.

KSTAR UPS: KSTAR's industrial-grade UPS systems feature a three-proof protective coating to protect circuit boards, along with built-in dust filters to ensure reliable operation in harsh environments. They have also passed comprehensive and rigorous testing to meet high reliability standards.

KSTAR Battery: KSTAR batteries feature a comprehensive anti-leakage solution (Patent No. ZL 2007 2 0196379.3), providing enhanced safety and reducing maintenance requirements. They also perform reliably in high-temperature environments.

KSTAR PDC: KSTAR's power distribution cabinet is a new-generation PDC developed to address the risk of single-point failures in equipment rooms. It collects comprehensive energy data and provides accurate electrical parameter information for easier monitoring and management.
