Description
(54) ПУСКОВОЙ ОРГАН тОКИ1 ЮВКИ от КАЧАНИЙ(54) STARTING ORGAN TOKI1 SWEETS

Изобретение относитс к электротехиике и может быть использовано в устройствах релейной защиты энергосистем.The invention relates to electrical engineering and can be used in devices for relay protection of power systems.
В технике релейтюй зашиты известно устройство блокировш от качаний дистанционной защиты, которое БВОДИТ ее в работу при возникноионии повреждени и блокирует (запрещает ее работу) в нормальном режимеИ при возникновении качаний и асинхронного хода. Пусковой )Q орган блокировки от качаний представл ет собой реле максимального напр жени или тока обратной последовательности l .In the relay protection technique, it is known a device that blocks from the swings of distance protection, which makes it work when damage occurs and blocks (prohibits its operation) in normal mode and when a swing and asynchronous move occurs. The starting) Q blocking device against swinging is a relay of maximum voltage or current of negative sequence l.
Недостатком данного устройства вл - 15 етс мала чувствительность к составл ющим тока повреждени , обусловленна тем, что в норхшльном режиме на выходе фильтра обратгтой последовательности может по вл тьс с.1ипственный небаланс, 20 вызванный естогтп-ониой разностью нагрузки по фазпм и эксплуатационными изменени ми наст;1Т14, от которого исполт1тельный орган быть .отстроен.The disadvantage of this device is that the sensitivity to components of the current of damage is low, due to the fact that in normal mode the output of the reverse sequence filter may appear with. 1 unbalance, 20 caused by the phase difference and operating conditions ; 1T14, from which the executive authority is to be discharged.
Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту вл етс пусковой орган блокировки от качаний, содержащий линию Ъадержки и исполнительный элемент с запоминанием срабатывани , включенный на разность величин входа и выхода лиши; задержки.Closest to the proposed technical essence and the achieved effect is a starting blocking device against oscillations, which contains a delay line and an actuating element with actuation memory, which is connected to the difference between the values of input and output of lishy delays.
Благодар линии задержки, котора имеет выходную величину, равную входной по абсолютному значению, но сдвинутую на 18О , напр жение (ток) на входе исполнительного элемента в нормальном режиме и при нормальной частоте равно нулю. При изменении нагрузки, в частности различи нагрузки по фазам, выходна величина фильтра обратной последовательности может существенно возрасти , однако благодар линии задержки напр жение на исполнитолг ном элементе также равно нулю 2 .Due to the delay line, which has an output value equal to the input absolute value, but shifted by 18 °, the voltage (current) at the input of the actuator in normal mode and at normal frequency is zero. When the load changes, in particular, the difference in the load across the phases, the output value of the negative-sequence filter can increase significantly, however, due to the delay line, the voltage on the executive element is also zero 2.
