Abstract: The paper deals with simulation of both dynamics and control of power plant superheaters. Superheaters are heat exchangers that transfer energy from flue gas to superheated steam. A composition of superheater, its input and output pipelines, and fittings is called a superheater assembly. Inertias of superheater assembly are often decisive for design of a steam temperature control system. Mathematical model of a superheater assemble is described by sets of nonlinear partial differential equations. The accuracy of the mathematical model is the center of the problem of simulation. Dominant role plays the accuracy of the mathematical model of the superheater. To discuss the accuracy of the mathematical model, the model was applied to the output superheater assemble of the 200 MW generating block of the actual operating power plant. To analyze the accuracy of the mathematical model, the system was agitated by test signals. Experiments carried out at the power plant were!
simulated mathematically. Then, data obtained by the measurement were compared with simulation results. Comparison leads to the verification of both the accuracy and the serviceability of the mathematical model discussed.
