摘　　要：超级不间断电源(UPS)系统利用多种能源联合供电,提高负载供电可靠性。随着系统中能源状态的改变,系统架构和工作模式也发生变化。探讨了超级UPS系统动态模型,为系统的控制、保护等分析和设计提供帮助。从单个变换模块大信号模型出发,建立了计算量低、精确度高的超级UPS系统的动态模型。最后,通过实验进行了验证。Super uninterruptible power supply（UPS） uses different types of energy sources to provide power supply, improving the reliability of power supply largely.As the state of energy sources in the system changes, the system＇s configuration and operation modes change to ensure power supply reliability.This paper has investigated dynamic model of super UPS system, preparing for the analysis and design of the system＇s control and protection.Large signal models of the single modules are built at first, then dynamic model of super UPS system is built with reduced calculation complexity and high accuracy.Finally, the model is provided by real experiment results on the prototype.

关 键 词：不间断电源 动态模型 可靠性
