Description
направлению с экономическим или соЬпадает, но превосходит его по величине более чем в два раза, то выключатель отключают.direction with economic or coincides, but exceeds it more than twice, the switch is turned off.
На фиг. 1 показан график зависи .мости потерь актизвной мощности йР в замкнутой сети от величины и направлени перетока через секционнь й выключатель; на фиг, 2 - структурна схема устройства, реализующего предлагаемый способ.FIG. Figure 1 shows a graph of the dependence of the potential loss of the active power iR in a closed network on the magnitude and direction of the flow through the section switch; Fig, 2 is a block diagram of a device that implements the proposed method.
Из графика потерь (фиг, 1) следует целесообразность отключени выключател , если фактический переток не совпадает по направлению с экономическим Рд или совпадает, но превосх здит его по величине более чем в два раза, и целесообразность включени выключател , если фактический переток совпадает с экономическим по направленрпо и не превосходит его по величине более чем в два раза.From the loss schedule (FIG. 1), it is advisable to turn off the switch, if the actual flow does not coincide in direction with the economic RD or coincides, but it is more than double in size, and it is advisable to turn on the switch if the actual flow coincides with the economic value Directed by and does not exceed it more than doubled.
Устройство, реализующее предлагаел1ый способ, содержит, (фиг, 2) измерительный блок 1, подключенный к трансформаторам 2 тока и трансформаторам 3 напр жени , блок 4 контрол положени секционного выключател ,. блок 5 определени перетоков мощности логические блоки 6, 7, 8, 9 и 10, элементы типа И, ИЛИ, И 11,12, 13, Кроме того, устройство содержит блок 14 отключени и блок 15 включени секционного выключател 16,The device implementing the proposed method contains, (FIG. 2), a measuring unit 1 connected to current transformers 2 and voltage transformers 3, a section switch position monitoring unit 4,. unit 5 for determining the power flow logic blocks 6, 7, 8, 9 and 10, elements of type AND, OR, AND 11.12, 13; In addition, the device contains a switch-off unit 14 and a block 15 for switching on a sectional switch 16,
Таким образом, в разомкнутом режиме линии с двухсторонним питанием целесообразность ее замыкани опре ел етс по разности напр жений на ее концах, а в замкнутом состо нии линии целесообразность ее размыкани определ етс по величине и направлению перетока активной мощности через секционный выключате ль..Thus, in open line mode with two-way power, the expediency of its closure is determined by the difference in voltage at its ends, and in the closed state of the line, the expediency of its disconnection is determined by the magnitude and direction of the flow of active power through the section switch.
Преимуществом предлагаемого способа вл етс также то, что вс информаци , необходима дл управлени , реЖ1;1мом сети, получаетс непосредственно в месте установки секционного вьаключател , что исключает необходимость применени телемеханической аппаратуры.The advantage of the proposed method is also that all the information needed for control, SP1; the 1st network, is obtained directly at the installation site of the section key, which eliminates the need to use telemechanical equipment.
Предлагаемый способ повышает экономичность работы электрических сетей , поскольку автоматическое управление режимами позвол ет снизить потери мощности и энергии в лини х,The proposed method improves the efficiency of electrical networks, since automatic control of the modes allows to reduce power and energy losses in lines
