Регулятор демпфирования колебаний мощности для статического преобразователя напряжения объектов возобновляемой генерации

   В настоящее время возобновляемые источники энергии (ВИЭ) являются неотъемлемой частью программ развития электроэнергетических систем (ЭЭС). Установлено, что в объектах генерации, работающих на базе ВИЭ, для преобразования энергии используются силовые статические преобразователи напряжения (СПН). С одной стороны, использование СПН дает определенные преимущества (возможность работы во всех квадрантах PQ-диаграммы, возможность подключения ВИЭ к слабой сети). С другой стороны, широкое применение ВИЭ с использованием СПН снижает общую инерцию ЭЭС, что увеличивает вероятность появления нежелательных незатухающих колебаний мощности, снижающих устойчивость работы ЭЭС. Для обеспечения надежной работы ЭЭС с ВИЭ с СПН необходимо модернизировать систему автоматического управления СПН с учетом требований, предъявляемых к традиционной генерации в составе ЭЭС. В данной статье представлены результаты применения регулятора демпфирования колебаний мощности, реализованного в СПН, который повышает устойчивость ЭЭС.
