VOLTAGE MANAGEMENT SYSTEM FOR LOW-VOLTAGE DISTRIBUTION SYSTEM

Title:

VOLTAGE MANAGEMENT SYSTEM FOR LOW-VOLTAGE DISTRIBUTION SYSTEM

Document Type and Number:

Japanese Patent JP2022007664

Kind Code:

A

Abstract:

To provide a novel voltage management system for a low-voltage distribution system.SOLUTION: A voltage management system 10 for maintaining a voltage of a low-voltage distribution system 16a within a predetermined range includes: a first voltage adjustment device (a reactive power compensation device) 30 for performing three-phase unbalance suppression control of a high-voltage distribution system 3; and a second voltage adjustment device (a reactive power compensation device) 20 having a reactive power compensation function for controlling a voltage of the low-voltage distribution system connected to the high-voltage distribution system via a transformer Tr to be constant. A plurality of low-voltage distribution systems are connected to the high-voltage distribution system, and a second voltage adjustment device is provided in each low-voltage distribution system.SELECTED DRAWING: Figure 1
