A dynamic mathematical model for once-through boiler-turbine units with superheated steam temperature

To absorb more renewable energy generation into power grid, once-through boiler-turbine (OTBT) units are now required to operate in a wide load range while maintaining high safety and efficiency. Superheated steam temperature (SST), adjusted by spray water and feedwater together, plays a critical role on operational safety and economy. However, the models of OTBT units in existing literature have not reflected this essential interrelationship,...
