Рассмотреть проблему определения изменения в топологии электрической сети, возникающей вследствие отключения/включения одной из линий электропередачи. Разработать алгоритм обнаружения изменения состояния линии в реальном времени, используя вектора напряжений в узлах электрической сети и вектора токов в линиях, полученные от устройств синхронизированных векторных измерений (УСВИ) во время переходного процесса. Провести экспериментальные исследования на 14-узловой тестовой схеме электрической сети. МЕТОДЫ. Поставленная задача решена методом из области искусственного интеллекта, таким как машинное обучение, в частности "глубокое обучение". РЕЗУЛЬТАТЫ. В статье описана актуальность темы, предложено применение метода определения состояния линий с помощью классификатора на основе сверточных нейронных сетей (СНС). Проведены расчеты для различных архитектур СНС с различным количеством временных срезов от момента изменения состояния линии. Доказана эффективность совместного использования УСВИ и СНС при решении данной задачи. ЗАКЛЮЧЕНИЕ. Предложено решение определения изменения состояния линии в переходном режиме с помощью классификатора сверточных нейронных сетей, используя векторные измерения напряжения и тока в реальном времени. Получена высокая точность, вплоть до 100 %, определения состояния линии, независимо от зашумления данных. Изменение топологии сети определяется в самом начале переходного процесса практически мгновенно, что позволит оператору несколько раз в течение первых секунд идентифицировать состояние линии, чтобы убедиться в правильности принимаемых решений.</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE. To consider the problem of detecting changes in a power grid topology that occurs as a result of the power line outage / turning on. Develop the algorithm for detecting changes in the status of transmission lines in real time by using voltage and current phasors captured by phasor measurement units (PMUs) are placed on buses. Carry out experimental research on IEEE 14-bus test system. METHODS. This paper proposes a method from the field of artificial intelligence such as machine learning in particular "Deep Learning" to solve the problem. Deep Learning arises as a computational learning technique in which high level abstractions are hierarchically modelled from raw data. One of the means to effectively extract the inherent hidden features in data are Convolutional Neural Networks (CNNs). RESULTS. The article describes the topic relevance, offers to apply the method for detecting status of lines using a CNN classifier. The combination of different CNN architectures and the number of time slices from the moment of line status change are used to detect the power grid topology. The effectiveness of the joint use of PMUs and CNN in solving this problem has been proven. CONCLUSION. A solution for the line status change detection in the transient states using a CNN classifier is proposed. A high accuracy of the line status detection was obtained despite the influence of noise on measurement data. A change in the network topology is detected at the very beginning of the transient state almost instantly. It will allow the operator several times during the first seconds to identify the line state in order to make sure that the decisions made are correct.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрическая сеть</kwd><kwd>топология</kwd><kwd>синхронизированные измерения</kwd><kwd>глубокое обучение</kwd><kwd>сверточные нейронные сети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>power network</kwd><kwd>topology</kwd><kwd>phasor measurement unit</kwd><kwd>deep learning</kwd><kwd>convolutional neural networks</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">Мокеев А.В.
