This dataset is developed to investigate the dynamic coupling characteristics of boiler and turbine systems during flexible low-load operation of ultra-supercritical (USC) units, through the approach of combining on-site data acquisition and modeling & simulation. The dataset encompasses three core contents: (1) Boiler-turbine dynamic coupling characteristics under variable load conditions; (2) Working fluid flow velocity and heat storage characteristics of water walls under various operating conditions; (3) Boiler-turbine steady-state coupling characteristics under furnace-side disturbances. Key operational data including load, main steam parameters, flow rate and other critical metrics were collected from the unit's Distributed Control System (DCS). Additionally, simulation models were built based on Apros, Fluent and Dymola platforms to acquire detailed parameter sequences during deep load regulation and variable load processes. The dataset presents the time-varying patterns of parameters such as wall temperature, load and energy, quantitatively characterizes the coupling process, and contains dynamic data of steam temperature and wall temperature of water walls under multiple operating conditions ranging from 25% to 100% of the turbine heat acceptance (THA) load. This dataset uncovers the influence of load ramping rate on system dynamic characteristics under low-load conditions, as well as the flow and heat transfer characteristics of water walls at different loads, providing theoretical foundations and data support for the flexible and safe operation of ultra-supercritical units.
