Abstract
Способ контроля аварийного отключения, успешного автоматического повторного включения (АПВ) и последующего ложного отключения головного выключателя (ГВ) линии электропередачи, отличающийся тем, что с момента появления броска тока короткого замыкания (КЗ) начинают отсчет времени выдержки срабатывания защиты ГВ, при этом контролируют момент его исчезновения, и если в момент окончания отсчитываемого времени ток КЗ исчезнет, то делают вывод об аварийном отключении ГВ, с момента исчезновения тока КЗ начинают отсчет времени выдержки АПВ ГВ, при этом контролируют появление броска рабочего тока, и если в момент окончания этого времени он появится, то делают вывод об успешном АПВ ГВ, с момента появления броска рабочего тока начинают отсчет времени выдержки срабатывания защиты с ускорением при этом контролируют исчезновение рабочего тока, и если в момент окончания этого отсчета времени рабочий ток исчезнет, то делают вывод о ложном отключении ГВ линии электропередачи.A method for controlling emergency shutdown, successful automatic restart (AR) and subsequent false shutdown of the main switch (GV) of the power line, characterized in that from the moment of the appearance of the inrush short circuit (short circuit), they start the countdown of the operation time of the GV protection, while monitoring the moment its disappearance, and if at the end of the counting time the short-circuit current disappears, then a conclusion is made about the emergency shutdown of the hot water, from the moment the short-circuit current disappears, they start the countdown of the shutdown time of the hot water reclosure, p At the same time, the occurrence of an inrush of the operating current is controlled, and if it appears at the end of this time, then they conclude that the automatic reclosure of HV is successful, from the moment of the appearance of an inrush of the operating current, the response time of the protection with acceleration begins to count, while the disappearance of the operating current is controlled, and if Since the end of this countdown, the working current disappears, then they conclude that the HV power line is false disconnected.
