Abstract: Изобретение относится к области электротехники. Предложены способ и устройство для разгрузки в электроэнергетической системе (ЭС). Технический результат заключается в повышении надежности ЭС. ЭС содержит устройство, которое электрически соединяет одну или более фидерных линий нагрузки с ЭС, при этом каждая из фидерных линий нагрузки подает энергию потребителям. Способ включает: слежение за электрической частотой ЭС и слежение за параметром стабильности частоты, который зависит от скорости изменения электрической частоты. Когда отслеживаемая частота меньше или равняется по меньшей мере одному заранее определенному пороговому значению частоты отключения, а отслеживаемый параметр стабильности частоты равняется или вышел за пределы по меньшей мере одного заранее определенного порогового значения параметра стабильности частоты, устройство генерирует управляющий сигнал на отключение указанной по меньшей мере одной фидерной линии нагрузки.  Использование параметра стабильности частоты, который зависит от скорости изменения частоты, в дополнение к фиксированному падению частоты в качестве критерия того, когда следует выполнять разгрузку, обеспечивает возможность задержки или даже предотвращения разгрузки, а следовательно, снижает риск превышения частоты, которое может привести к неустойчивости или выключению ЭС. 3 н. и 10 з.п. ф-лы, 10 ил.
