Title:
VOLTAGE ADJUSTING DEVICE AND DETERMINING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2019033638
Kind Code:
A
Abstract:
To solve a problem of determination by mistake when equipment having a constant voltage control function is connected to the load side in the determination in the power substation direction using the change amount in a voltage.SOLUTION: A voltage adjusting device in which voltage adjusting means adjusts a voltage on the side where a power substation does not exist within a prescribed voltage range based on the power substation direction stored in a power substation direction storage unit 179A and a power substation determination unit 175 determines the power substation direction by using the change amount of the voltage by the voltage adjustment includes a reactive power change amount detection unit 177 for detecting the change amount before reactive power tap changeover by the voltage adjustment and a determination unit 178 for determining whether a device having a power constant control function is interconnected to a distribution line by using the detection result of the reactive power change amount detection unit 177 to prevent voltage adjustment operation based on improper substation direction information.SELECTED DRAWING: Figure 4
