DISTRIBUTION LINE SUPERVISORY CONTROLLER DEVICE AND METHOD AND RECORDING MEDIUM RECORDING SOFTWARE FOR DISTRIBUTION LINE SUPERVISORY CONTROL

摘要

PROBLEM TO BE SOLVED: To measure at a low cost and accurately a load in each section of a distribution line. ;SOLUTION: In a controlling calculator 52, voltage and a phase value obtained by simultaneously measuring all together in a switch slave station in both ends of each section are collected by a voltage phase collection part 54 and stored in a voltage phase difference file 55. In a section load calculation part 57 by a phase difference, based on an impedance file 56 and the voltage phase value file 55, a phase difference component in both ends of each section is calculated further with a voltage value and impedance in this section used, and a section passing current is calculated. On condition, a difference component between the passing current in the section in a substation side connected through a switch of closed condition, that is, in a power source side and the passing current in the section in a load side, set as a section load in the section in the power source side, is stored in a section load file 318.;COPYRIGHT: (C)2001,JPO
