<p>PROBLEM TO BE SOLVED: To provide a transformer type voltage regulation device capable of regulating a voltage of a distribution line according to a simple method.SOLUTION: A storage section 3 stores a maximum value P of effective power, a maximum value Q of ineffective power, resistance R and reactance X of a distribution line within a voltage regulation responsibility range. A current measuring section 6 measures a current flowing in the distribution line. A voltage measuring section 2 measures an output voltage Vs. The control section 4 increases the output voltage Vs when Vs-P×R/Vs is less than a lower limit value in the case where the measured current exceeds a first threshold, and decreases the output voltage Vs when Vs+Q×X/Vs exceeds an upper limit value in the case where the measured current is less than a second threshold value that is equal to or smaller than the first threshold.</p> |
