Matematický model vstřiku vody do horkého vzduchu s možností odloučení kondenzátu modelovaný prostřednictvím S-funkcí v Simulinku

Abstract

This thesis addresses the mathematical model, the injection of water into the hot air that occurs in experimental power plant in Ostrava- Vítkovice, which is part of a flexible energy sytem. Water injection is carried out at the power plant in the injector. Injection of water into the hot compressed air in the power plant obtains power gas, which is crucial for driving compressor and turbine generator. The mathematical model in this thesis is therefore part of mathematical model of the power plant and its main output is temperature power gas that occurs in the injector for mixing water and air. Water injection into the hot air is the technological process that can cause the saparation condensate water. Therefor, this mathematical model is widespread at the output of the posibility of determining the value of the separated amount of condensate water dutiny injection. The individua chapters of the thesis are given both theoretical information about the thermodynamics of water vapor and are described mathematical methods and algorithms model the injector to determine the required outputs. The result of the mathematical model are verified by simulations and real data measured from a power plant.
