阐述一种积木式UPS逆变电源结构、包含一种多模态融合STS静态智能切换开关,通过自动寻优与高速计算的故障单元智能隔离算法,建立了UPS逆变电源的在线动态故障识别及无缝自愈控制方法技术。实验结果表明,所提自愈策略可明显降低UPS逆变电源故障风险,且长期运行过程中故障出现后可迅速隔离自愈,系统保持在常规应用的可靠状态中。

This paper describes a modular UPS inverter power structure,which includes a multimodal fusion STS static intelligent switching switch.Through an intelligent isolation algorithm for fault units through automatic optimization and high-speed calculation,an online dynamic fault identification and seamless self-healing control method technology for UPS inverter power is established.The experimental results show that the proposed self-healing strategy can significantly reduce the risk of UPS inverter power failure,and can quickly isolate and self-heal after a fault occurs during long-term operation,keeping the system in a reliable state for conventional applications.
