Being setting manner of the line drop compensator which compensates the voltage drop which it occurs setting manner of the line drop compensator and hindrance decision manner of systematic voltage management,

摘要

PROBLEM TO BE SOLVED: To provide technology for appropriately setting a line voltage drop compensator in a power distribution system including a power distribution line where voltage rises.;SOLUTION: When a voltage rise power distribution line exists in a plurality of power distribution lines, temporary transmission voltage from a power distribution transformer is calculated based on voltage at a highest voltage point in the voltage rise power distribution line and a lowest voltage point in the power distribution line having voltage distribution where voltage drops in accordance with a distance from the power distribution transformer. In details, transmission voltage Vac is selected so that a center value in a voltage fluctuation range, which is obtained by adding voltage rise width Vk from transmission voltage of the transformer to voltage at the highest voltage point with voltage drop width Vj from transmission voltage of the transformer to voltage at the lowest voltage point becomes Vdc.;COPYRIGHT: (C)2010,JPO&INPIT
