Abstract: Both the modeling and the load regulation capacity prediction of asupercritical power plant are investigated in this paper. Firstly, an indirectidentification method based on subspace identification method is proposed. Theobtained identification model is verified by the actual operation data and the dynamic characteristics of the system are wellreproduced. Secondly, the model isused to predict the load regulation capacity of thermal power unit. The power, main steam pressure, main steam temperature and other parameters aresimulated respectively when the unit load is going up and down. Under theactual constraints, the load regulation capacity of thermal power unit can bepredicted quickly.
