Abstract
Способ ограничения тока перегрузки для преобразователя напряжения, который применяется с однополюсной или двухполюсной топологией в гибкой системе передачи электроэнергии постоянного тока. Когда система управления полюса получает команду ограничения тока перегрузки с водяным охлаждением, в одно и то же время меняются команды активной и реактивной мощностей в соответствии с конкретным наклоном характеристики, так что абсолютное значение тока плеча преобразователя снижается при постоянном наклоне характеристики и гарантируется падение активной мощности и реактивной мощности до нуля в одно и то же время, и цели преобразователя, заключающейся в ограничении нагрузки с водяным охлаждением, можно достичь посредством уменьшения тока плеча. После отмены команды ограничения перегрузки по мощности с водяным охлаждением, полученной системой управления полюса, текущая величина активной мощности и неактивной мощности остается без изменений, при повторном получении команды ограничения перегрузки по мощности с водяным охлаждением снижение продолжается на основании текущих величин мощности, пока мощность не снизится до нуля. Согласно этому способу в преобразователе напряжения однополюсной или двухполюсной топологии может быть реализована функция ограничения перегрузки по мощности с водяным охлаждением, при этом во время перегрузки может гарантироваться безопасная работа клапана преобразователя, а рабочий процесс является простым, надежным и легким для выполнения.
