UPS是一种以整流器、逆变器和静态开关等为主要元件,稳压、稳频输出的电源设备,是连接厂用电与负荷的一种电器设备,其作用是向负荷持续提供高品质、稳定且不间断的交流电源。在大型火力发电厂中,为保证电厂自动化系统、计算机监控系统等的安全运行,机组分散控制系统(DCS)、厂级实时监控系统(SIS)、管理信息系统(MIS)、厂用电监控系统(ECMS)、辅助车间程序控制系统和通信系统等均采用交流不间断电源装置(UPS)供电。UPS
UPS is a rectifier, inverter and static switch as the main components, voltage regulator, frequency output power equipment, is connected to plant electricity and load of an electrical equipment, its role is to continue to provide high-quality load , Stable and uninterrupted AC power. In large-scale thermal power plants, in order to ensure the safe operation of power plant automation systems, computer monitoring systems, etc., DCS, factory-level real-time monitoring system (SIS), MIS, (ECMS), auxiliary workshop program control system and communication system are powered by AC UPS. ups
