| Abstract: | The paper describe the basic working principle of uninterrupted power supply （UPS） system and four kinds of working modes, analyze the existing problems of using UPS in our factory, and bring forward three kinds of installation transformation schemes： （ 1 ） connecting two original different types of UPS in series, （2） connecting two original different types of UPS in parallel, and （3） connecting a original UPS with a new UPS, which is the same type as the original 40KVA,with the same design parameters and a dual redundant parallel technology. Combining the power distribution actual situation, the advantages and disadvantages of the above three kinds of schemes are analyzed, and the third option is selected as the best installation alteration scheme, which improves the system reliability. |
