摘　　要：电厂烟气排放连续监测系统又称为CEMS,其规范了烟气排放连续监测系统用电设备供电电源配置原则及技术条件。目前对火力发电企业的固定污染源烟气排放的监管日趋严格,因此寻求一种更为可靠的CEMS供电方式迫在眉睫。为提高某发电厂CEMS的供电可靠性,利用电厂UPS电源资源,通过对原有的CEMS供电方案进行优化设计。对比并分析了几种改造CEMS供电方案的优缺点,得出了比较合适的发电厂烟气连续排放监测系统电源系统,达到了烟气排放监测数据的统一管理。The continuous monitoring system of flue gas emissions in power plants,also known as CEMS,regulates the principles and technical conditions of power supply configuration of power supply for electrical equipment in continuous flue gas emission monitoring system.At present,the regulation of fixed pollution source flue gas emissions by thermal power generation enterprises is becoming increasingly stringent,so it is urgent to seek a more reliable CEMS power supply method.In order to improve the power supply reliability of a power plant's CEMS,the original CEMS power supply scheme is optimized by using the power plant's UPS power supply resources.The advantages and disadvantages of several modified CEMS power supply schemes are compared and analyzed,and a more suitable power supply system for the continuous emission monitoring system of power plant flue gas is obtained,which achieves unified management of monitoring data of flue gas emission.
