Delta UPS Watches Over Tiangong-1 Launch

On the evening of September 29th, 2011, China successfully launched its new target spacecraft Tiangong-1 into space. As the nation celebrated, Delta Greentech announced that a Delta UPS solution was on duty in the server room of the Xi'an Satellite Control Center to ensure the continuous availability of critical equipment used for satellite tracking and control during the launch.

Tiangong-1 is the name for China's first space lab. The newly launched target spacecraft will link up with Shenzhou 8, Shenzhou 9 and Shenzhou 10 over the next two years to establish the first Chinese space laboratory. The launch of Tiangong-1 represents an important milestone in China's development of manned spaceflight. For this launch, responsibility for tracking and control was assigned to the Xi'an Satellite Control Center.

Critical functions of the satellite control center's server room include spacecraft tracking data and the processing of remote sensing parameters. A stable and reliable Uninterruptible Power Supply (UPS) is therefore essential to ensure the power supply of the orbital satellite tracking & communications data server room. After a careful review of many UPS supplier brands on the market, a team of experts firmly decided on Delta's UPS solution for its high availability and exceptional quality.

Delta Greentech designed a custom solution for China's satellite control center based on the expected workload of the tracking & communications data server room, differences in the levels of importance, and the architectural layout of the building. For the distributed power supply and key areas, the custom solution used Delta's NT80kVA 1+1 redundant power supply and a total of 16 UPS units rated between 7kVA and 320kVA. All UPS equipment was also managed using Delta's proprietary central management software. The software allowed for centralized power supply monitoring of single-phase Amplon N+ series and three-phase NT series located on different floors. Delta's UPS systems also had the advantages of scalability and smart monitoring, greatly reducing the amount of required system maintenance and the risks associated with system operation.

For this project, Delta Greentech adopted a flexible and distributed UPS power supply solution based on the user's requirements. The smart monitoring solution was also seamlessly integrated with the hardware of the UPS, greatly enhancing the reliability, availability and maintainability of the satellite control center's power supply. Delta's UPS made an outstanding contribution to China's aerospace industry by helping ensure a successful launch for Tiangong-1.
