Project Background

As urban rail transit networks continue to expand, metro systems have become a critical component of modern city infrastructure. Every day, thousands of passengers rely on stable and efficient metro operations for transportation. Behind every metro station is a complex network of critical systems, including signaling equipment, communication networks, security monitoring systems, ticketing platforms, station control systems, and emergency facilities. These systems require uninterrupted power to ensure safe and reliable operation.

To further enhance the reliability of its station infrastructure, multiple stations across the Xiamen Metro network launched power system upgrade projects aimed at strengthening critical power protection capabilities. Given the importance of metro operations, the customer required a highly reliable UPS solution capable of supporting critical loads around the clock while providing flexibility for future expansion and maintenance.

After a comprehensive technical evaluation, GOTTOGPOWER was selected to supply multiple GTM150/30 and GTM180/30 Modular UPS systems together with supporting battery solutions, providing continuous power protection for key metro station infrastructure.

Customer Challenges

Metro stations operate continuously throughout the day and serve as essential public transportation hubs. Any interruption to critical systems can affect station operations, passenger services, and overall transportation efficiency.

One of the primary challenges faced by the customer was ensuring uninterrupted operation during utility power disturbances. Critical systems such as signaling, communications, ticketing equipment, access control systems, and station monitoring platforms must remain operational even during unexpected power events.

In addition, metro stations are distributed across multiple locations throughout the city, requiring a power protection solution that is easy to deploy, maintain, and expand. The customer also sought a system capable of supporting future station upgrades and increasing power demands without requiring complete infrastructure replacement.

Operational reliability was another key consideration. Since metro facilities operate continuously, maintenance activities needed to be carried out with minimal impact on station operations.

GOTTOGPOWER Solution

To address these requirements, GOTTOGPOWER deployed multiple GTM150/30 and GTM180/30 Modular UPS systems across various Xiamen Metro stations, together with corresponding battery backup systems.

The modular architecture of the GTM Series provides excellent scalability and availability. The systems allow power modules to be added or replaced without interrupting protected loads, enabling flexible capacity expansion and simplified maintenance.

The UPS systems are designed to deliver stable and clean power to critical station equipment, protecting sensitive electronics from voltage fluctuations, power disturbances, and utility outages. Combined with battery backup systems, the solution ensures uninterrupted operation during power interruptions and provides sufficient backup time for emergency power systems to engage.

The compact modular design also helps optimize equipment room space while simplifying installation and future system upgrades.

Protecting Critical Metro Infrastructure

The UPS systems support a wide range of mission-critical applications throughout the metro stations, including communication networks, signaling support equipment, security monitoring systems, automatic fare collection systems, station management platforms, emergency broadcasting systems, and passenger information displays.

These systems play a vital role in ensuring passenger safety and maintaining efficient station operations. Any power disruption could impact information transmission, station management functions, or emergency response capabilities.

Through online double-conversion technology, the GTM150/30 and GTM180/30 Modular UPS systems continuously isolate connected equipment from utility power anomalies, providing stable and reliable power under all operating conditions. This significantly reduces the risk of service interruptions and improves the overall resilience of station infrastructure.

Project Implementation

Prior to deployment, GOTTOGPOWER engineers conducted detailed site assessments and load analyses for each station to determine the optimal UPS configuration and battery capacity.

The installation process included UPS deployment, battery integration, electrical connection verification, system commissioning, and operational testing. Comprehensive testing procedures were performed to verify system performance under various operating conditions, including utility failure simulations, battery discharge tests, load transfer tests, and full-load operation verification.

The systems successfully met all performance requirements and were commissioned according to project specifications.

Project Results

Following deployment, the Xiamen Metro stations achieved significantly improved power reliability for critical infrastructure systems. The UPS platforms now provide continuous protection against utility disturbances, ensuring uninterrupted operation of key station equipment and enhancing overall operational stability.

The modular design offers flexibility for future expansion as station requirements evolve, while hot-swappable modules simplify maintenance and reduce operational risks. The intelligent monitoring capabilities further improve visibility into system performance and support proactive maintenance management.

By establishing a reliable critical power infrastructure, the project contributes to safer, more efficient, and more dependable metro operations across the network.

Conclusion

Reliable power protection is essential for modern urban rail transit systems. Through the successful deployment of multiple GTM150/30 and GTM180/30 Modular UPS systems and supporting battery solutions, GOTTOGPOWER delivered a dependable power platform for critical metro station operations in Xiamen.

The project demonstrates GOTTOGPOWER’s expertise in transportation infrastructure, modular UPS technology, and mission-critical power protection. With stable products, professional engineering support, and efficient project execution, GOTTOGPOWER continues to help transportation operators ensure safe and uninterrupted service for millions of passengers every day.
