Description
Повреждение находитс на линии между проходными подстанци ми 2 и 3.The damage is on the line between the walk-through substations 2 and 3.
На модели рассматриваемого участка проходные подстанции I-4 представлены узлами 7-.10, высоковольтные линии, соедин ющие эти подстанции, - посто нными сопротивлени ми 11, 12, 13, а присоединени 5 и 6 - переменными сопротивлени ми 14 и 15. Трансформаторы, соедин ющие проходные подстанции 1-4 с потребител ми , на модели показаны посто нными сопротивлени ми 16-19.In the model of the considered site, the I-4 pass-through substations are represented by nodes 7-10, the high-voltage lines connecting these substations are constant resistances 11, 12, 13, and connections 5 and 6 are variable resistances 14 and 15. Transformers connecting throughstations 1–4 with consumers, the model shows constant resistances 16–19.
Аварийный режим, возникщий на реальном участке сети, имитируют па модели подключением к узлам 8 и 9 регулируемых источников ЭДС 20, 21 Е и Е, величина которых равна напр жени м, зафиксированным в момент аварии на проходных подстанци х 2 и 3.Emergency mode occurring in the real network section imitates the model by connecting to the nodes 8 and 9 of the regulated sources EMF 20, 21 E and E, the magnitude of which is equal to the voltages recorded at the time of the accident at the substations 2 and 3.
При имитации аварийного режима на модели через регулируемые источники ЭДС 20, 21 пропускают токи / и /, которые обратно пропорциональны рассто нию от проходных подстанций 2 и 3 до места повреждени на высоковольтной линии между ними . Эти токи измер ют амперметрами 22, 23.When imitating the emergency mode on the model, through the regulated sources EMF 20, 21 pass currents / and /, which are inversely proportional to the distance from the passable substations 2 and 3 to the place of damage on the high voltage line between them. These currents are measured by ammeters 22, 23.
Суммарный ток / и / замер ют амперметром 24. Измен (уменьша или увеличива ) напр жени регулируемых источников ЭДС 20, 21 Е и Е, добиваютс , чтобы показани амперметра 24 были численно равны длине высоковольтной линии между проходными подстанци ми 2 и 3 в единицах длины, например в километрах. Тогда показани амперметра 22 численно равны рассто нию в километрах до места повреждени от проходной подстанции 2, а показани амперметра 23 - рассто нию от проходной подстанции 3.The total current (and /) is measured by an ammeter 24. By varying (decreasing or increasing) the voltage of the regulated sources of EMF 20, 21 E and E, the ammeter 24 is measured to be numerically equal to the length of the high voltage line between passable substations 2 and 3 in units of length , for example, in kilometers. Then, the readings of the ammeter 22 are numerically equal to the distance in kilometers to the place of damage from the transceiver substation 2, and the readings from the ammeter 23 to the distance from the transceiver substation 3.
Аналогично определ ют рассто ни до места повреждени и при авари х на других лини х рассматриваемого участка сети.The distances to the damage location and in case of accidents on other lines of the considered network section are determined similarly.
Использование данного способа позвол ет проверить работу фиксирующих приборов, восстановить утер нные показани фиксирующих приборов и заменить певерпые н непосредственно в единицах длины отсчитать рассто ние от места повреждени до концов поврежденной линии, в результате чего более достоверно и точно определ етс место повреждени .Using this method allows you to check the operation of the fixing devices, restore the lost readings of the fixing devices and replace the distance points in units of length to count the distance from the damage point to the ends of the damaged line, as a result of which the damage place is more accurately and accurately determined.
