摘要
发电厂自动控制系统关系到整个发电厂的安全、稳定运行,其供电电源系统能否提供优质可靠的电源决定了自动控制系统诸多重要功能的实现。本文介绍了某350MW火电机组交流不间断电源系统(UPS)在运行中存在缺陷,通过对电源接入方式、整流滤波功能、蓄电池供电可靠性等方面进行分析,提出了相应的改进方案。
Power plant automatic control system has close relation with the safe,stable operation of whole powerplant,whether the power supply system can provide high quality and reliable power determine realization ofmany important functions of automatic control system. This paper introduces operation defects in uninterruptiblepower system(UPS) of a 350 MW thermal power unit,analyses from power supply access mode,rectifier filterfunction,reliability of battery power supply and puts forward corresponding improvement schemes.
