cze	Přibližný matematický model přehříváku páry	V článku je popsána konstrukce matematického modelu řízeného elektrárenského přehříváku páry. Přehřívák se skládá z dvou subsystémů, které mohou být identifikovány odděleně - chlazení páry vstřikováním studené vody a subsystém ohřevu páry.	heat systems;mathematical modeling;system identification;control systems
eng	Approximate Mathematical Model of a Steam Overheater	We describe a construction of a mathematical model of a controlled powerplant steam overheater. The overheater consists of two subsystems that can be identified separately - cooling steam by water injection and the heating steam part. The model is subsequently to be used in design of a cascade-type control system for regulation of outlet temperature of overheated steam. The second subsystem has distributed parameters and for the purposes of control design it has to be simplified. One way of such an approximation is proposed in the paper. The procedure of estimation of the model parameters from measured service data is described in a stand-alone paper in the same proceedings.	heat systems;mathematical modeling;system identification;control systems
