Modeling and Simulation of Partial Blocks of Flexible Energy System in MATLAB&Simulink for Temperature Control of Steam/Air Mixture

چکیده
The presented article describes two basic technological blocks of so called Flexible power unit which is located in the grounds of the Vı́tkovice company Ostrava in the Czech Republic. The experimental unit was established to research the use of potential energy in a mixture of dry air and superheated steam, which is called air/steam mixture. Creation of air/steam mixture is carried out by mixer whose mathematical model is described in this article. Connection of the mixer to the surrounding FES technology is carried out by steel pipes whose mathematical model is also described in this article. This article aims to outline the temperature control of air/steam mixture at selected technological blocks of flexible energy system. The control is performed through linearized model of the mixer in operating point, which corresponds to the operating point of mixer in a real energy unit. Mathematical models of mixer and steel pipelines are implemented in S-functions with the aim of easy simulation of these blocks in Simulink.
