Maximum KPD=0.915861 график зависимости КПД от величины G₁ будет иметь вид:



По оси абсцисс отложен G₁, а по оси ординат отложен КПД системы. Из графика видно, что КПД демонстрирует нелинейную зависимость от параметров. Максимальное значение КПД находится около величины 0.921601 (достигается при G₁= 0.5554). Однако не при всех значениях G₁ ограничения задачи выполняются. Так точка достижения глобального максимума находится за пределами области выполнения ограничений задачи и действительное максимальное значение КПД равно 0.915861, которое достигается при G₁= 3.1096.

ЗАКЛЮЧЕНИЕ

В результате выполнения курсового проекта по дисциплине «Моделирование, оптимизация и управление теплотехническими системами» мы составили математическую модель рассматриваемого в проекте теплотехнического объекта. Его программная реализация на ПЭВМ позволяет решать целый ряд задач по исследованию и модернизации объекта. В проекте мы провели анализ нашей теплотехнической системы, её сравнение с аналогичными. Также мы провели численное исследование системы. Исследовав нашу теплотехническую систему при разных параметрах теплоносителей, мы выявили наиболее экономичный режим работы (провели параметрическую оптимизацию) и построили зависимость критерия эффективности (в нашем случае КПД) от параметров системы.
