Abstract
The paper describes a procedure of obtaining estimated values of parameters of a model of a controlled powerplant steam overheater from measured service data. A construction of a mathematical model of the overheater is described in a stand-alone paper in the same proceedings. The overheater consists of two subsystems that can be identified separately – cooling steam by water injection and heating steam part. Statistical estimation of parameters from measured data is complicated by the fact that the disturbances influencing the outlet temperature are not pure random. Moreover, since the plant is under feedback, correlation between the disturbances and the system input has to be considered.
