Preface: Data centers serve as fundamental infrastructures for transmitting, storing, displaying, and computing data and information. Diesel generator sets are among the widely utilized emergency power sources in data centers. During sudden municipal power outages, the UPS or high-voltage DC backup batteries of data centers enter discharge mode to maintain the continuity of power supply to IT equipment. Simultaneously, the diesel generator sets installed in the data centers swiftly start and synchronize to provide power backup to the entire facility. Properly configuring diesel power systems ensures safe, reliable, and continuous equipment operation. Googol Power in Chongqing has been deeply engaged in the data center field for many years and has developed several sets of high-horsepower high-voltage diesel generator systems suitable for large-scale data center backup power. In 2011, we obtained the patent certificate for”High-Horsepower High-Voltage Diesel Generator Power System and Its Power Supply Method for Large-Scale Data Storage Centers”(Patent No. : ZL 2011 1 0104902. 6). The system components include high-power high-voltage generator sets, transformers, lightning protection, surge suppressors, ATS switching systems, low-voltage distribution centers, parallel UPS systems, DC/AC power distribution systems, maintenance systems, and emergency power distribution systems. Employing a 1+1 mode helps avoid equipment damage and data loss due to power interruptions, granting IT personnel more orderly time to start backup systems or alternative power sources.
