Выявлены причины, по  которым автономная  работа является нежелательной; рассмотрены последствия автономно-несинхронной работы участков сети при изоляции. Эти проблемы характерны для современных электрических распределительных сетей Smart Grid. Для выявления изолированного режима использовали пассивные и активные методы. Пассивные методы – это только наблюдение за напряжением и/или частотой в точке общего присоединения, и если измеряемые величины выходят за установленные пределы, инвертор отключается. Несмотря на свою простоту, пассивные методы не могут обеспечить выявление изолированного режима, особенно в тех случаях, когда количество распределенной выработки электроэнергии равняется нагрузке потенциально изолированного участка сети. Активные методы предполагают воздействие со стороны инвертора на сеть с тем, чтобы выявить отклонение от нормальных параметров режима в точке общего присоединения. Такие методы помогают лучше выявлять изолированный режим, но их использование снижает качество работы энергосистемы.</p><p>Отмечено, что распознание режима автономной работы участков сети, по существу без нулевой зоны необнаружения, возможно только с использованием эффективных антиизолирующих схем, таких как подключение к отключенному сегменту сети батареи конденсаторов. При необходимости обеспечения повышенной живучести и бесперебойности электроснабжения рекомендуется предусматривать в инверторах для источников распределенной генерации блокировки функции обнаружения автономной работы.</p></abstract><trans-abstract xml:lang="en"><p>The article analyzes the methods affecting autonomous operation regimes of the powergrid sections with distributed electric-power sources (distributed generation) whose connection to the electric-power grid is realized by means of special distributed generation inverters. The authors evidentiate the reasons for which autonomous operation is undesirable; examine consequences of the autonomous asynchronous operation of the grid-sections during islanding. These problems are innate for the modern Smart Grid networks. Islanding detection methods include passive and active ones. The passive methods rely only on observation of the voltage and/or frequency at the point of common coupling (PCC) disconnecting the inverter if the  measured  values  are  outside  the  specified  limits.  Despite  their  simplicity,  passive methods cannot assure reliable islanding detection, especially in the cases when distributed generation power equals the power of loads in the potential grid-island. The active methods assume the inverter affecting the grid with the view of detecting deviation from the standard regime parameters in the PCC. Although these methods have much better islanding detection ability, their utilization reduces the power-grid operation quality.</p><p>The paper holds that the grid-sections autonomous regime detection without virtually no failure-to-detect zone is only possible with employment of effective anti-islanding schemes such as connecting capacitor batteries to the disconnected power-grid sector. If appropriate providing enhanced survivability and continuity of power supply, the authors recommend providing islanding detection lock option in the inverters of the distributed generation sources.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интеллектуальная сеть Smart Grid</kwd><kwd>распределенная генерация</kwd><kwd>фотоэлектрические системы</kwd><kwd>ветровая энергетика</kwd><kwd>режим изолированной работы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intellectual network Smart Grid</kwd><kwd>distributed generation</kwd><kwd>photovoltaic systems</kwd><kwd>wind power engineering</kwd><kwd>islanding regime</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">Bower, W.
