Network-Design of Virtual Drum Boiler Feedwater Control System

To solve the difficult problem of the thermal process experiment in education and training, this paper develops a drum boiler feedwater control system based on the Networked Control System Laboratory (NCSLab). The task of automatic control of the feed water of the drum boiler is to adapt the water supply of the boiler to the evaporation capacity of the boiler to maintain the water level of the drum within the specified range while maintaining a stable feedwater flow. For both supercritical and ultra-supercritical units, the boiler is The once-through boiler has no steam drum, but there will be a steam-water separator, which is equivalent to a drum. NCSLab is a Web-based platform for remote control of physical devices and virtual devices. At present, the remote virtual drum feedwater control experiment on NCSLab provides a feasible online solution for the thermal process control experiment and also provides technical support for the more complex thermal process control system in the future.
