      <abstract xml:lang="ru">
        <p>Сжатый воздух широко используется во многих отраслях промышленности как один из видов безопасного технологичного энергоносителя. Затраты энергии на производство и распределение сжатого воздуха достигают 10 % от общих энергозатрат в экономически развитых странах. Анализ систем производства и распределения сжатого воздуха на предприятиях промышленного сектора показывает, что эффективность систем находится на сравнительно низком уровне. Это обусловлено тем, что данным системам уделяется недостаточно внимания ввиду того, что энергетический мониторинг систем сжатого воздуха имеет определенные трудности – наличие сложных и разветвленных воздухопроводных сетей, обладающих уникальными характеристиками; низкой чувствительностью оборудования, потребляющего сжатый воздух; сложностью проведения аудита пневматического оборудования, которое находится в постоянной работе. В статье проведен анализ вариантов снижения затрат на производство и распределение сжатого воздуха. Одним из перспективных направлений снижения затрат на распределение сжатого воздуха является своевременное обнаружение и ликвидация утечек, возникающих во внешней воздухопроводной сети предприятия. Поставленная задача решается аппаратно-программным мониторингом давления сжатого воздуха в ключевых точках сети. Предлагаемая методика позволяет в режиме реального времени обнаруживать возникающие утечки воздуха в воздухопроводной сети и подавать команды обслуживающему персоналу на их своевременную локализацию. Данная методика была апробирована в промышленных условиях предприятий компании «АЛРОСА» на воздухопроводной сети рудника «Мир» Мирнинского горно-обогатительного комбината и показала удовлетворительную сходимость расчетных значений утечек с фактическими. Практическая значимость полученных результатов состоит в том, что разработанный метод мониторинга утечек воздуха в воздухопроводной сети отличается простотой, несложной программной реализацией и позволяет своевременно локализовать утечки, сокращая тем самым непроизводительные расходы энергоносителя на предприятиях.</p>

        <p>Compressed air as a type of safe technological energy carrier is widely used in many industries. In economically developed countries energy costs for the production and distribution of compressed air reach 10 % of the total energy costs. The analysis of compressed air production and distribution systems in the industrial sector shows that the efficiency of the systems is at a relatively low level. This is due to the fact that insufficient attention is paid to these systems since the compressed air systems energy monitoring has certain difficulties – the presence of complex and branched air pipeline networks with unique characteristics; low sensitivity of the equipment which consumes compressed air; the complexity of auditing pneumatic equipment that is in constant operation. The article analyzes the options for reducing the cost of production and compressed air distribution. One of the promising ways to reduce the compressed air distribution cost is timely detection and elimination of leaks that occur in the external air supply network of the enterprise. The task is solved by hardware-software monitoring of compressed air pressure at key points in the network. The proposed method allows real-time detecting of emerging air leaks in the air duct network and sending commands to maintenance personnel for their timely localization. This technique was tested in the industrial conditions of ALROSA enterprises on the air pipeline network of the Mir mine of the Mirninsky Mining and Processing Plant and showed satisfactory convergence of the calculated leakage values ​​with the actual ones. The practical significance of the obtained results is that the developed method for monitoring air leaks in the air duct network is simple, it requires an uncomplicated software implementation and allows to localize leaks in a timely manner, thereby reducing unproductive energy costs at the enterprises.</p>
