Известно оборудование для мониторинга выбросов труб малого диаметра, однако для труб большого диаметра (15 м и более), имеющихся в Республике Беларусь, соответствующие технические решения отсутствуют. В работе рассматривается задача автоматизации отбора пробы дымовых газов на основе электропривода в трубах большого диаметра. Для обеспечения оптимальной траектории движения пробоотборника в сечении трубы необходимо использовать асинхронный электродвигатель с преобразователем частоты и датчиком положения. Предложены функциональная схема системы управления, которая содержит программируемый логический контроллер для формирования режима движения, а также метод расчета параметров и выражения для формирования сигнала задания для режима непрерывного отбора пробы. Поскольку диапазон регулирования скорости возрастает по мере увеличения диаметра дымовой трубы, в зависимости от него может быть применено скалярное либо векторное частотное управление. Предложено выражение для расчета оптимального значения параметра N инкрементального датчика положения и скорости (энкодера), что способствует обоснованному выбору датчика. Представлены результаты имитационного моделирования, подтверждающие эффективность предложенного метода расчета параметров привода пробоотборника.</p></abstract><trans-abstract xml:lang="en"><p>To organize reliable control over emissions from chimneys of energy facilities, automatic monitoring systems are needed. Equipment is known for monitoring emissions from small-diameter chimneys, but for large-diameter pipes (15 m or more) available in our Republic, there are no corresponding technical solutions.  The paper examines the problem of automating the sampling of flue gases based on an electric drive in large-diameter chimneys. To ensure the optimal trajectory of the sampler in the chimney section, it is necessary to use an asynchronous electric motor with a frequency converter and a position sensor. A functional diagram of the control system is proposed, which contains a programmable logic controller for generating the motion mode, as well as a method for calculating parameters and expressions for generating a task signal for continuous sampling mode. Since the range of speed control increases as the diameter of the chimney increases, depending on it, scalar or vector frequency control can be applied. An expression is proposed for calculating the optimal value of the parameter N of an incremental position and speed sensor (encoder), which contributes to a reasonable choice of sensor. The results of simulation modeling are presented, confirming the effectiveness of the proposed method for calculating the parameters of the sampler drive.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электропривод</kwd><kwd>частотное управление</kwd><kwd>мониторинг выбросов дымовой трубы</kwd><kwd>энкодер</kwd><kwd>имитационное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electric drive</kwd><kwd>frequency control</kwd><kwd>chimney emission monitoring</kwd><kwd>encoder</kwd><kwd>simulation</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">Системы автоматического контроля и учета выбросов загрязняющих веществ тепловых электростанций в атмосферу.
