Abstract: Based on “Internet +”, data sharing, big data analysis, improved grayneural network(UGMN)model analysis and other technologies,continuous emission monitoring system(CEMS),environmentally distributed control system(DCS),programmable logic controller(PLC),thermal power plant plantlevel safety instrumented system(SIS)/management information system(MIS),grouplevel production marketing and realtime monitoring system,grouplevel fuel management system and other environmental protection database are established.These database that base on multiple data sources have developed a multidata sources environmental protection intelligent supervision system for thermal power plants which can realize realtime monitoring,trend analysis,intelligent prediction,report management,alarm management,etc.The system can comprehensively improve the health of environmental protection equipment and pollutant emission standards of thermal power enterprises,and provide a more efficient and intelligent platform for flue gas emission management and environmental supervision.

Key words: Internet+, thermal power plant, environmental protection facilities, flue gas pollutants, intelligent supervision system
