As the demand for information technology continues to rise, various industries increasingly rely on large data centers for processing massive amounts of data. Large data centers are characterized by their large scale, typically exceeding 500 square meters, and housing numerous server racks. Their energy needs manifest in aspects such as high capacity, stringent reliability requirements, and frequent upgrade and expansion needs. The hardware and software involved are numerous and complexly configured. Features like high reliability, scalability, and intelligence are essential for the foundational equipment of large data centers.

Detailed Information
A typical infrastructure system for large data centers is illustrated in Figure 1, encompassing precision power supply systems, environmental control systems, and centralized monitoring systems. Given the critical importance of the business operations supported by large data centers, they are generally constructed according to the international Tier 4 standard, with reliability requirements exceeding 99.99999%.

Large data centers host a wide variety of equipment, all requiring high reliability in power quality. Statistics indicate that most failures in large data centers are related to the power supply system. With the support of UPS systems and DC uninterruptible power supply systems, combined with well-designed distribution systems, the reliability of modern large data centers has reached unprecedented levels. As business demands rapidly evolve, modern power systems in large data centers must not only ensure high reliability but also address urgent needs for energy efficiency, flexibility, high density, and intelligence.

The principle diagram of the large data center solution provided by Yongxin Energy Technology Co., Ltd. is shown in Figure 2. The utility power supply and generator set serve as the two main power sources for the data center, switched automatically via an ATS (Automatic Transfer Switch). After centralized or decentralized distribution, the AC power is connected to the UPS system, communication power supply, surge suppressor (TVSS), and other equipment. The reliability of the UPS uninterruptible power supply system is ensured by the internationally leading LBS (Dual Bus System).

The UPS system has evolved from single-unit configurations to 1+1 parallel systems, then to N+1 configurations, and now to the dual bus system, significantly enhancing reliability. The dual bus system ensures the independence of the two power sources for dual-power loads within the data center, greatly improving the reliability of power supply for such loads. Single-input loads utilize an STS (Static Transfer Switch) to select one of the two UPS systems for power supply, while the other remains in hot standby. In the event of a failure in the main UPS power circuit, the STS can seamlessly connect the other UPS system, ensuring the reliability of power supply for single-input loads as well.
