Аналіз сучасних методів і підходів до математичного моделювання та оптимізіції параметрів технологічних процесів в енергетичному устаткуванні енергоблоків ТЕС і АЕС

Abstract

The materials of the article consider the classification of modern methods of system analysis, the main provisions of the theory and means of mathematical modeling of technological processes in power equipment, designed for automated control of complex thermal power systems. To consider methods and approaches to mathematical modeling and optimization of process parameters in TPP (thermal power plants) and NPP (nuclear power plants) power units. Modern steam turbine power units of thermal and nuclear power plants are complex technical, thermal power systems. Complex thermal power system is a set of interconnected and interacting elements and subsystems of different technological purposes, which form an inseparable whole, providing the system of some complex function in the form of electricity and heat production and which are described by a rather complex mathematical model. The theory of system analysis and mathematical modeling is widely used to select the structures and parameters of the technological processes of power units. Analysis of literature sources on the existing methods of mathematical modeling and selection criteria, schemes of technological processes and approaches to creating mathematical models of the functional state of steam turbine power units, showed the need to improve them to take into account operational reliability.
