Research on Intelligent Monitoring Technology for Thermal Power Plant Based on DCS System
Based on the actual operation of a 2×350 MW super-critical unit heating power plant,presenting the overall architecture of the intelligent monitoring,through three modules such as intelligent alarm,automatic adjustment and automatic handling of anomalies,it forms an intelligent monitoring system of abnormal classification and classification alarm reminder,automatic parameter adjustment and optimization,precise control of small indicators and automatic intervention of important anomalies.To realize the man-machine combination of monitoring disk work,reduce the pressure and labor intensity of monitoring personnel,improve the quality of monito-ring disk,reduce the workload of overhaul and maintenance,and improve the intelligent level of power plant.The intelligent monito-ring technology is completed using existing DCS system resources and is fully implemented by the technical personnel of the power plant.It saves hardware and personnel costs,and later upgrades and maintenance can be implemented by power plant technicians,making it simple and practical.After the implementation of intelligent monitoring technology,the power consumption rate of the power plant has decreased by 0.5%,and the coal consumption for power generation has decreased by 1.5 g/kWh,which providing reference for the intelligent construction of thermal power plants.
