In DC power systems,the uninterruptible power supplies(UPS)and the inverter power supplies are common application devices that play an important role in ensuring the reliability and stability of power supply.Under the mode of intelligent distributed control,they all have the ability of self diagnosing and self repairing.The integrated DC and AC uninterruptible power supply system(hereinafter referred to as the integrated power supply)is a comprehensive system used for power supply,which can provide both DC and AC power sources simultaneously.The integrated power system can achieve economic and reliable operation of the power grid,save energy and reduce energy consumption,and provide strong technical support and warranty services.It combines high-frequency switching,computer,power electronics and other technologies,and adopts a hot plugging redundant modular design.Its monitoring unit has functions such as remote control,remote measurement,and remote information processing,and is widely used in unmanned monitoring of substations.This paper takes the application of AC uninterruptible power supply and inverter power supply in DC power supply systems in smart grids as the research background,analyzes the advantages and characteristics of AC uninterruptible power supply and inverter power supply,discusses the composition of AC uninterruptible power supply and inverter power supply in substations,and designs a practical application system of AC uninterruptible power supply,and wishes to provide reference for the optimization,upgrading and application research of DC power supply systems.
