METHOD OF DETERMINING INSTALLATION POSITION AND ADJUSTMENT AMOUNT OF REACTIVE POWER ADJUSTMENT DEVICE, PROGRAM, AND APPARATUS FOR DETERMINING INSTALLATION POSITION AND ADJUSTMENT AMOUNT OF REACTIVE POWER ADJUSTMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of determining an installation position and an adjustment amount of a reactive power adjustment device which determines an installation position of a reactive power adjustment device for adjusting reactive power of a three-phase distribution line, and an adjustment amount of reactive power to be adjusted by the reactive power adjustment device.SOLUTION: A method of determining an installation position and an adjustment amount of a reactive power adjustment device includes: a first step of calculating a first reactive power adjustment amount of a first position so that a value of a voltage unbalance rate of the first position of a three-phase distribution line becomes equal to or less than a first value; a second step of calculating a first voltage unbalance rate from the upstream side of the three-phase distribution line to the downstream side; a third step of calculating a second reactive power adjustment amount of a second position so that a value of a voltage unbalance rate of a second position of the three-phase distribution line becomes equal to or less than a second value; a fourth step of calculating a second voltage unbalance rate from the upstream side of the three-phase distribution line to the downstream side; a fifth step of determining the installation position on the basis of the calculation results of the second and fourth steps; and a sixth step of determining the adjustment amount on the basis of the calculation results of the first and third steps and the determination result of the fifth step.
