Studies of Dynamic Processes and Simulation Results in the Exchange of Energy in Energy Components

Abstract

The paper presents some results of numerical simulation of processes for the problem of stabilization of thermal regimes at dynamic exchange of thermal energy in the energy components of generation, cogeneration, trigeneration (polygeneration with H2C), described by aperiodic links with delay and perturbations. The results of the research are presented in relative values for the comparison of the open-loop heat exchange system with perturbations and for the control options by deviation of the output coordinate, as well as by perturbation and by their combination. In particular, in the form of graphical dependences of the output temperature, dynamic perturbation and control action for five predetermined variants of parameters of dynamic links with the calculated duration of processes of 200 seconds. This makes it possible to study the stabilizing properties of heat exchange equipment when they are used in similar technologies for coal-fired, gas-fired or other thermal power plants, as well as for industrial process thermal equipment. The simulation tool MatlabSimulink was used.
