Исследование направлено на обоснование начальных параметров пара в двухконтурных теплофикационных парогазовых установках (ТПГУ) с перспективной отечественной газотурбинной установкой ГТЭ-65. В качестве критерия использован показатель относительной экономии топлива при комбинированной выработке энергии по сравнению с раздельной. На базе САПР United Cycle разработана имитационная модель для анализа влияния давления свежего пара в контурах высокого и низкого давления на эффективность ТПГУ. Модель позволяет проанализировать диапазоны давлений свежего пара для контуров: высокого давления – от 10 до 18 МПа; низкого – от 1,0 до 2,0 МПа. Установлено, что повышение давления пара в ТПГУ на базе перспективной установки ГТЭ-65 с традиционно принятых для установок конденсационного профиля 7–8 до 15–17 МПа обеспечивает суммарную относительную экономию топлива на уровне 38,0–38,1 %. Увеличение параметров пара в контуре низкого давления с традиционно принятого значения 0,5–0,8 МПа до уровня 1,3–1,5 МПа также позволяет повысить экономию топлива. Предложены практические рекомендации по использованию докритических параметров давления пара, исходя из опыта эксплуатации и технических ограничений существующего оборудования.</p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to the implementation of current plans for import substitution and improving the efficiency of the energy sector of the Russian Federation. The study aims to substantiate the initial steam parameters in double-circuit combined-cycle heating plants with a promising domestic gas turbine installation GTE-65. The indicator of relative fuel savings in combined energy generation in comparison with separate energy generation was used as a criterion. A simulation model for analyzing the effect of fresh steam in high- and low-pressure circuits on the efficiency of double-circuit combined-cycle heating plants has been developed on the basis of United Cycle CAD. The model allows analyzing the pressure ranges of fresh steam for circuits: for the high-pressure circuit – from 10 to 18 MPa; for the low-pressure one – from 1.0 to 2.0 MPa. It has been established that increasing the steam pressure in the double-circuit combinedcycle heating plants based on the promising GTE-65 installation from the traditionally accepted 7–8 MPa for condensation profile installations to 15–17 MPa provides a total relative fuel saving of 38.0–38.1 %. An increase in steam parameters in the low-pressure circuit from the traditional value of 0.5–0.8 to the level of 1.3–1.5 MPa also makes it possible to improve fuel savings. Practical recommendations on the use of subcritical steam pressure parameters are proposed, based on operational experience and taking into account technical limitations of existing equipment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теплоэлектростанция</kwd><kwd>когенерационная установка</kwd><kwd>парогазовая установка</kwd><kwd>теплофикационная установка</kwd><kwd>теплофикация</kwd><kwd>относительная экономия топлива</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thermal power plant</kwd><kwd>cogeneration plant</kwd><kwd>combined-cycle plant</kwd><kwd>heating plant</kwd><kwd>heating system</kwd><kwd>relative fuel savings</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гринчук, А.
