摘　　要：随着大容量火电机组的快速发展及其控制水平的不断提高,对UPS电源可靠性的要求越来越高。为了提高UPS供电可靠性,除选用高可靠性UPS外,另一有效的途径就是采用冗余配置。此外,每台UPS的后备电池可按交流电源停电时间为30 m in计算;UPS的交流输入工作电源应接于机组厂用电的保安段,交流输入旁路电源接于机组厂用电的低压工作段。With quick development of the large sized coal - fired power units and continuous improvement of their control level the requirements for reliability of UPS will be more strict. In order to increase the power supply reliability of UPS an effective way is to use redundant configuration except application of reliable UPS. In addition, the standby battery of each UPS can be calculated based on 30 min outage for AC power source. The work power source of AC input for UPS should be connected to the security section of the unit auxiliary power and AC input bypass power source connected to the LV work section of the unit auxiliary power.
