Abstract

Modular UPSs have more than ten years of history, and have been widely used in large data centers thanks to their features of high availability, high scalability, easy maintenance, high efficiency, and many other advantages. The reliability of a modular UPS primarily depends on the system architecture design which should be simple and decoupled to avoid single points of failure. Key parts such as power modules, control modules, the system communication bus, power supply, and fans must be redundant. The UPS system reliability also depends on the system fault detection and isolation mechanisms, which ensure that a faulty unit is promptly detected and automatically isolated from the system so that remaining operational units can continue supplying power safely. Lastly, real-time detection and health condition evaluation of vulnerable devices ensure long term reliable operation of the power supply system. Leveraging its powerful and professional test verification platform, Huawei verifies and optimizes its modular UPS products through 21 special reliability tests, ensuring strong UPS adaptability to power grids, various environments, and loads.

如何保证模块化UPS的高可靠性

模块化ups已经有十多年的历史，以其高可用性、高扩展性、易维护、高效率等优点，在大型数据中心得到了广泛的应用。模块化UPS的可靠性主要取决于系统架构设计，系统架构设计应简单，解耦，以避免单点故障。关键部件如电源模块、控制模块、系统通信总线、电源、风扇等应采用冗余设计。UPS系统的可靠性还依赖于系统的故障检测和隔离机制，确保故障单元被及时发现并自动与系统隔离，从而使剩余的运行单元继续安全供电。最后，对脆弱设备进行实时检测和健康状态评估，保证供电系统长期可靠运行。华为凭借强大的专业测试验证平台，通过21项专项可靠性测试，对模块化UPS产品进行验证和优化，确保UPS对电网、各种环境和负载具有较强的适应性。
