Разработана программа экспериментальных исследований на модели турбоустановки с имитацией неисправностей и получения вибросигналов. Эксперимент на основе гомостатичного метода проверки сигнала окнами Хэмминга в частотной, временной и модуляционной областях и единых исходных данных позволяет определить наиболее перспективные для идентификации характеристики сигнала. Разработана методика осуществления мониторинга состояния турбогенераторов в автоматическом режиме для своевременного оповещения персонала тепловой электростанции (ТЭС) о появлении признаков предаварийных ситуаций, а также о характере неисправностей методом прогнозирования состояния предаварийной ситуации с помощью сверточных нейронных сетей с реализацией в виде рекуррентного автоэнкодера. Применяется кластеризация, и выявляются кластеры, соответствующие спектрограммам предаварийных ситуаций. Результативность применения гомостатичного метода в сочетании с корреляционным анализом основана на модели принятия решений, более подробно изложенной в других работах. Рассмотрено использование глубинных нейронных сетей при обнаружении классов признакового пространства предаварийных ситуаций на промышленных турбогенераторах. Дана методика подготовки обучающей выборки и обучения глубинной нейронной сети при классификации аномалий спектрограмм. Диагностика дефектов выполняется на основе заранее сформированных экспериментальных баз данных и обобщенных баз знаний, ставящих в соответствие повышенный уровень виброактивности с вызвавшими ее причинами. Различные дефекты активных частей турбогенератора, возникающие в процессе эксплуатации, требуют аварийного останова генератора, что является крайне нежелательным событием для станции.</p></abstract><trans-abstract xml:lang="en"><p>A method is proposed for recognizing pre-emergency conditions of rotary installations based on the use of the Hamming window and advanced Deep Learning techniques in retrospective analysis of the results of accounting for the factors of operation of a turbine generator, diagnostics and control under critical impacts. A program of experimental studies on the model of a turbine plant with simulation of faults and receiving vibration signals has been developed. An experiment based on the homostatic method of checking the signal with Hamming windows, in the frequency, time and modulation domains and common initial data, allows one to determine the most promising signal characteristics for identification. A method has been developed for monitoring the state of turbine generators in an automatic mode for timely notification of the CHPP personnel about the appearance of signs of pre-emergency situations, as well as about the nature of faults by the method of predicting the state of a pre-emergency situation using convolutional neural networks implemented in the form of a recurrent autoencoder. Clustering is applied and clusters are identified that correspond to the spectrograms of pre-emergency situations. The effectiveness of the use of the homostatic method in combination with correlation analysis is based on the decision-making model described in more detail in other works.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейронные сети</kwd><kwd>предиктивная аналитика</kwd><kwd>окна Хэмминга</kwd><kwd>прогнозирование неисправ-ностей</kwd><kwd>вибродиагностика</kwd><kwd>анализ спектрограмм</kwd><kwd>вибрационный стенд</kwd><kwd>турбогенератор</kwd><kwd>реккурентный автоэнкодер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neural networks</kwd><kwd>predictive analytics</kwd><kwd>Hamming windows</kwd><kwd>fault prediction</kwd><kwd>vibration diagnostics</kwd><kwd>spectrogram analysis</kwd><kwd>vibration stand</kwd><kwd>turbine generator</kwd><kwd>recurrent autoencoder</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках гранта «Университетский» ФГБОУ ВО «МИРЭА  – Российский технологический университет» по теме «Выявление неявных неисправностей ответственных роторных агрегатов с помощью анализа темпоральных аномалий спектрограмм виброизмерений» (приказ № 1953 от 27.11.2019).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sobra J., Vaimann T., Belahcen A.
