断器の入り切り制御を行なうものであるから。In general, the amount of reactive power in the nine circuits varies depending on the load of that circuit, so the amount of reactive power to be controlled is often matched to that circuit. In other words, the amount of reactive power in the circuit is set as the center position setting value, and the detected amount of reactive power is adjusted so as to be approximately in the vicinity of this center position setting value. In order to adjust such reactive power amount, a plurality of correction capacitors are provided, and these capacitors are sequentially connected to or disconnected from the controlled circuit according to the detected reactive power amount. There is a reactive power amount control device. However, in the conventional reactive power control device of Jinno Tane, the control state of each capacitor created by the control circuit is stored in the circuit, so when the control power of the high voltage circuit is cut off, the stored state disappears. When the power is restored,
This is because all the circuit breakers for capacitor on/off are once set to the "open" state to bring them to their initial state, and then the circuit breaker on/off control is performed according to the amount of reactive power.
電源断時の元の状態まで制御するのに時間を要し。It takes time to return to the original state when the power is turned off.
その分の電力が無駄になるという欠点があった。The disadvantage is that the amount of power is wasted.
この発明は、上記した従来装置の欠点を解消し。The present invention eliminates the drawbacks of the conventional devices described above.

ー！１ｈｒ。First, assuming an initial state in which capacitor 9a and everything else is disconnected from line 12, the amount of reactive power detected by controlled circuit 1 is far behind the reference position level set by CPU 2. is normal. in this case,
The amount of reactive power detected by the CPU 2 compared to the controlled circuit 1 is
Turn on the closing relay 5 times until it is equal to the center position setting level.
They are turned on sequentially from a to 3b... First relay! 1hr.

にしコンデンサ９Ｃが線路１２から切離される。The capacitor 9b is connected to the line 12 in the same manner as when the closing relay 6a is turned on. If the delay is still not compensated enough, add more! Turn on JL/-50 and connect capacitor 9C to line 12. In this state, if the detected reactive power amount of the controlled circuit 1 becomes approximately close to the center position setting level, the capacitor is not cut and the state continues as it is. On the other hand, if, for example, the three capacitors 9a, 9b, and 9C are connected to the line and the detection voltage exceeds the standard with respect to the center position setting level and becomes advanced, the cutoff relay 4C is turned on and the contact 4C is turned on. The capacitor 9C is disconnected from the line 12 by closing the circuit breaker 8C and passing a current through the circuit breaker coil 10C to turn off the circuit breaker 8C.

きる。When the power is turned on again, the pallet switch 5a
The on/off states of 5b...5f are taken into the CPU 2. Then, the process moves directly to the subsequent control of the amount of reactive power. In this case, pallet switches 5a, 5b and circuit breakers 8a, 8b
is turned on and the capacitors 9a and 9b are connected to the line 12, so there is no need to turn on the relays 3a and 3b when the power is restored, so that the next control can be carried out efficiently.

なうことができる。As described above, according to the reactive power amount control device of the present invention,
A self-holding circuit breaker is provided for multiple capacitors, and the circuit breaker opens and closes according to the control of the control circuit to protect the capacitors, and when the power is restored after a power outage, the circuit breaker is activated. Since the opening/closing operation status of the circuit breaker is imported into the control circuit section for subsequent control operations, it is possible to move on to other control operations based on the state where the opening/closing operation status of the circuit breaker is input into the control circuit section. This is good because there is no need to perform complicated operations such as setting the capacitor to the open state and then turning the relay on and off to return to the original state.
It is possible to efficiently control reactive power amount without wasting power consumption.
