<p><P>PROBLEM TO BE SOLVED: To improve a voltage drop in a distribution line even when self-terminal voltage is not within a settling range by regulating a transformer with a tap as much as possible. <P>SOLUTION: In a distribution system, voltage regulators 3 with a tap switching means of switching the tap of the transformer with the tap connected with the distribution line are disposed between the respective distribution lines of a plurality of zones respectively. The system comprises tap switching control devices 40 respectively provided corresponding to the respective voltage regulators and controlling tap positions, by applying tap switching commands to the voltage regulators so that the electricity amount of voltage or the like taken in through the self-terminal may become a reference electricity amount; and a coordination control device 9 for calculating tap positions of the respective voltage regulators, so that secondary side voltages of the all voltage regulators may be within the setting range, based on the electricity amount and the tap positions by a computation device 8 for transmitting them to the corresponding tap switching control devices, when the electricity amount of the voltage or the like transmitted from the respective tap switching control devices and the tap positions of the voltage regulators are received. <P>COPYRIGHT: (C)2003,JPO</p> |
