В связи с увеличением количества солнечных электростанций актуальной задачей становится автоматизация мониторинга их работоспособности. Поиск аномалий в работе солнечных электростанций – одна из основных составляющих мониторинга. Цель исследования заключается в разработке новых методик и программных алгоритмов поиска аномалий в работе солнечных панелей на основе результатов работы цифрового двойника, созданного и обученного по данным телеметрии солнечной электростанции.Методы. Методика основана на статистических исследованиях отклонений значений мощности в точке максимально эффективной работы солнечной панели, рассчитанной цифровым двойником. Кроме того, введено нормализованное значение мощности максимально эффективной работы солнечной панели для более точной кластеризации и поиска аномалий.Результаты. С помощью разработанной методики поиска аномалий в данных телеметрии за полгода наблюдений обнаружены 18 аномалий в работе солнечных панелей электростанции. Все случаи проанализированы на предмет причин возникновения аномалий в работе солнечных панелей.Заключение. Установлено, что при использовании в анализе отклонений нормализованных значений мощностей в точке максимальной мощности PN возможно обнаружение аномальной работы отдельных панелей. Рассчитан уровень отклонения нормализованных значений в точке максимальной мощности, свидетельствующий о наличии аномалии в работе солнечной панели.</p></abstract><trans-abstract xml:lang="en"><p>Objectives. In connection with the increase in the number of solar power plants, the automation of monitoring their performance becomes an urgent task. The search for anomalies in the operation of solar power plants is one of the main components of monitoring. The purpose of the study is to develop new methods and software algorithms for finding anomalies in the operation of solar panels based on the results of a digital twin created and trained according to the telemetry data of a solar power plant.Methods. The developed technique is based on statistical studies of deviations of power values at the point of maximum efficient operation of the solar panel calculated by the digital twin. In addition, a normalized value of the power in the maximum efficient operation of the solar panel was introduced for more accurate clustering and anomaly search.Results. Using the developed method of static search for half a year of observations, 18 anomalies were detected in the operation of the solar panels of the power plant. All cases are analyzed for the causes of anomalies in the operation of solar panels.Conclusion. It has been established that when using normalized power values in the analysis of deviations at the point of maximum power PN, it is possible to detect abnormal operation of individual panels. The level of deviation of the normalized values at the point of maximum power was calculated, indicating the presence of an anomaly in the operation of solar panel.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>солнечная панель</kwd><kwd>нормализованное значение мощности</kwd><kwd>поиск аномалий</kwd><kwd>точка максимальной мощности</kwd><kwd>солнечная электростанция</kwd><kwd>телеметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solar panel</kwd><kwd>normalized power value</kwd><kwd>anomaly search</kwd><kwd>maximum power point</kwd><kwd>solar power plant</kwd><kwd>telemetry</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">Dorin, P.
