Sinopsis

In this article the essentials of mathematical modelling and computer simulation of fossil power station dynamics are presented. Especially the requirements both to the model and to the computer programme as well as the modular structure of the calculation model and programme derived is described. This leads to the modelling of the steam generator by heat exchanger modules. The basic equations on which the calculation model is constructed are the laws of conservation for mass, momentum and energy. The equation system is set up and simplified. The simplifications are stated and discussed. Directions for the modelling of steam turbines, for the helping functions and for the mathematical solution of the equation system are given. With the calculation programme developed a carried-out superheater circuit with temperature control injection is calculated and the results are compared with existing measurements.
