Abstract
Изобретение относитс к области электромеханики. Цель изобретени - повышение надежности включени на параллельную работу генераторных агрегатов, резко отличающихс номинальной мощностью, и снижение аварийности. Устройство содержит блок 1 синхронизации, схемы запрета 2 и 6, блок 3 измерени активной мощности, пороговую схему 4, схему 5 сигнализации и согласующую схему 7. Сигнал на включение выключател генератора меньшей мощности с выхода схемы 2 запрета сформируетс в случае, если нагрузка генератора большей мощности не превышает допустимую дл генератора меньшей мощности, что контролируетс пороговой схемой 4. При этом на период синхронизации схема 6 запрета формирует сигнал, блокирующий подключение мощных потребителей. 1 ил.This invention relates to the field of electromechanics. The purpose of the invention is to increase the reliability of switching on the parallel operation of generating sets, which differ sharply in nominal power, and reducing accident rates. The device contains a synchronization unit 1, prohibition schemes 2 and 6, an active power measurement unit 3, a threshold circuit 4, an alarm circuit 5 and a matching circuit 7. A low power switch on signal of the lower power generator from the output of the prohibition circuit 2 is generated if the generator load is greater power does not exceed the permissible for the generator of lower power, which is controlled by the threshold circuit 4. At the same time, for the period of synchronization, the prohibition circuit 6 generates a signal that blocks the connection of powerful consumers. 1 il.
