Research on the Prediction of Load Regulation Capacity for Supercritical Thermal Power Unit

Both the modeling and the load regulation capacity prediction of a\r\nsupercritical power plant are investigated in this paper. Firstly, an indirect\r\nidentification method based on subspace identification method is proposed. The\r\nobtained identification model is verified by the actual operation data and the dynamic characteristics of the system are well\r\nreproduced. Secondly, the model is\r\nused to predict the load regulation capacity of thermal power unit. The power, main steam pressure, main steam temperature and other parameters are\r\nsimulated respectively when the unit load is going up and down. Under the\r\nactual constraints, the load regulation capacity of thermal power unit can be\r\npredicted quickly.
