РАЗРАБОТКА ЦИФРОВОГО ДВОЙНИКА ПРОЦЕССА СБОРКИ И ОЧИСТКИ КИСЛОЙ ВОДЫ

В нефтегазовой отрасли сбор и очистка кислой воды при дистилляции сырого газа является важным технологическим процессом. Оптимальное управление данным процессом позволит повысить эффективность производства, снизить экологические выбросы кислот и углекислого газа в окружающую среду и рациональнее использовать природные ресурсы на фоне растущих потребностей нефтегазовой индустрии. Данная работа посвящена проектированию цифрового двойника с использованием программного обеспечения компании Honeywell Unisim Design. Основное внимание уделено разработке и внедрению системы управления с разделением диапазона (англ. split-range control) в рамках динамической модели. Произведен анализ разработанной модели с историческими данными, где проверена достоверность модели. Разработана стратегия управления для промышленного контроллера C300 и HMI-интерфейс для операторов с целью интеграции цифрового двойника с распределенной системой управления Experion PKS. Цифровой двойник открывает новые возможности для создания и проверки новых схем управления, оптимизации параметров и настройки системы безопасности. По результатам опросов клиентов компании Honeywell внедрение цифровых двойников позволяет сократить капитальные затраты на проектирование более чем на 10%, сократить время разработки на 10% и увеличить производительность завода на 3–8 %.
