Design of Real-time Control System for Thermal Instrument Running State of Thermal Power Unit
The automatic data acquisition and real-time control system of thermal instrument running state of thermal power unit are designed.The overall framework of the thermal instrument operating status data self-acquisition and control system of thermal power units is constructed.After the on-site instrument layer combines thermal instruments with various sensors and actuators to collect the operating status data of thermal power units,the system is developed based on DNN dynamic feedforward superheated steam control model realizes accurate control of superheater outlet temperature,uses industrial Ethernet module of network communication layer to realize data transmission and interac-tion at each layer,and realizes control results display by upper computer.The experimental results show that the MAE and RMSE values of the system are 0.3℃and 0.4℃respectively.Under different intrusion attacks,the system data can be securely transmitted and interacted.
