摘要/Abstract

摘要： 通过对不间断电源系统（UPS）2种冗余配置方式的比较，结合电厂因UPS系统故障导致机组跳闸案例和UPS电源系统成功改造，提出直接并机加自动互投供电方式是UPS电源系统的最佳设计方案和可靠电源的保证，为火电机组的UPS设计和改造提供参考。

Abstract: Two redundant configuration schemes of UPS were compared. Combining with the example of unit tripping caused by UPS fault in power plant and the successful reformation of UPS system, an optimal design scheme of UPS was proposed, in which the output of two UPS directly parallel connected into load, and each of them can be put in automatically. The scheme can ensure the reliability of power supply, and provides a reference for UPS system design and reformation in thermal power plant.

Key words: uninterruptible power supply (UPS), redundant configuration, directly parallel connection, automatic mutual throw
