摘　　要：UPS并机系统作为保障电力供应连续性和稳定性的重要设备,在现代电力系统中发挥着关键作用。但随着电力需求的不断增长和电力网络的复杂化,UPS并机系统面临着各种潜在故障和问题。其中,直流母线过压故障是影响UPS并机系统正常运行的常见故障类型。直流母线过压会对UPS并机系统本身造成损坏,导致接入的电子设备遭受损坏或工作异常,进而影响到整个电力系统的稳定性和可靠性。文章分析了UPS并机直流母线过压故障的发生机理、诊断方法及影响因素,并提出相应的优化策略和措施,以提升UPS并机系统的运行稳定性和可靠性。通过对直流母线过压故障进行系统研究和分析,可以为UPS并机系统的设计、运行及维护提供理论指导,为电力系统的安全稳定运行作出积极贡献。The UPS parallel system,as an important equipment to ensure the continuity and stability of power supply,plays a crucial role in modern power systems.However,with the continuous growth of electricity demand and the complexity of power networks,UPS parallel systems are also facing various potential faults and problems.Among them,DC bus overvoltage fault is a common type of fault that affects the normal operation of UPS parallel systems.DC bus overvoltage can cause damage to the UPS system itself,as well as damage or abnormal operation of connected electronic devices,thereby affecting the stability and reliability of the entire power system.This article aims to conduct an in-depth analysis of the overvoltage fault of the UPS parallel DC bus,explore its occurrence mechanism,diagnostic methods,and influencing factors,and propose corresponding optimization strategies and measures to improve the operational stability and reliability of the UPS parallel system.Through systematic research and analysis of the overvoltage fault of the DC bus,theoretical guidance can be provided for the design,operation,and maintenance of the UPS system,and it can also make positive contributions to the safe and stable operation of the power system.
