POWER DISTRIBUTION TRANSFORMER TAP CONTROL SYSTEM AND POWER DISTRIBUTION TRANSFORMER TAP CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To manage a voltage of a whole distribution line such that the voltage falls within a proper range even if a large number of distributed power supplies are installed in the distribution line.;SOLUTION: A power distribution transformer tap control system includes: measurement information detection means for measuring an electrical quantity of a distribution line; distribution line state estimation means for estimating a voltage of the distribution line based on the electrical quantity measured by the measurement information detection means; and power distribution transformer tap determination means for determining a tap of a power distribution transformer connected with the distribution line such that a difference between a predetermined voltage target value of the distribution line and the voltage of the distribution line estimated by the distribution line state estimation means is minimized.;COPYRIGHT: (C)2014,JPO&INPIT
