This transformer-type voltage control device uses reactive power occurrence data (reactive power integrated value, positive greatest reactive power integrated value, and negative greatest reactive power integrated value) received from a reactive-power-controlling voltage control device to calculate the total reactive power integrated value, the total positive greatest reactive power integrated value, and the negative greatest reactive power integrated value, calculates a positive reactive power reserve on the basis of the total positive greatest reactive power integrated value and the total reactive power integrated value, calculates a negative reactive power reserve on the basis of the total negative greatest reactive power integrated value and the total reactive power integrated value, alters a tap position of the transformer-type voltage control device in a manner such that the positive reactive power reserve is greater than a positive-side threshold when the positive reactive power reserve is less than the positive-side threshold, and alters the tap position in a manner such that the negative reactive power reserve is greater than a negative-side threshold when the negative reactive power reserve is less than the negative-side threshold. |
