Рассматривается последовательность разработки модели анализа невозмущенного состояния теплоэнергетической гидравлической системы - системы теплоснабжения, которая является важным этапом проектирования и оптимизации системы. Проанализированы основные параметры системы, такие как тепловые нагрузки, потоки тепла, теплопередача через трубы и теплообменники, расположение и характеристики оборудования (котлы, насосы и т.д.). Выполнена разработка математической модели системы, которая должна учитывать все основные факторы, влияющие на теплообмен и эффективность работы системы. Модель представлена в виде системы уравнений и включает в себя такие параметры, как температура, давление, расход теплоносителя и др. На основе этой модели можно проводить анализ различных режимов работы системы, оптимизировать параметры и принимать решения по ее улучшению. При разработке модели учтена возможность различных возмущений. Для анализа невозмущенного состояния системы исключено влияние таких возмущений и рассмотрена ее базовая работа. При разработке модели анализа потокораспределения для теплоэнергетической системы применено энергетическое эквивалентирование. Разработанная модели анализа невозмущенного состояния теплоэнергетической системы позволит более точно проектировать и управлять такой гидравлической системой, улучшить ее эффективность и надежность.

The sequence of development of a model for analyzing the undisturbed state of a thermal power hydraulic system - a heat supply system, which is an important stage in the design and optimization of the system, is considered. The main parameters of the system are analyzed, such as thermal loads, heat flows, heat transfer through pipes and heat exchangers, location and characteristics of equipment (boilers, pumps, etc.). A mathematical model of the system has been developed, which should take into account all the main factors affecting heat transfer and the efficiency of the system. The model is presented in the form of a system of equations and includes parameters such as temperature, pressure, coolant flow, etc. Based on this model, it is possible to analyze various operating modes of the system, optimize parameters and make decisions to improve it. When developing the model, the possibility of various disturbances was taken into account. To analyze the unperturbed state of the system, the influence of such disturbances is excluded and its basic operation is considered. When developing a flow distribution analysis model for a heat and power system, energy equivalence was used. The developed model for analyzing the undisturbed state of a thermal power system will make it possible to more accurately design and control such a hydraulic system, improve its efficiency and reliability.
