SYSTEM AND METHOD FOR CONTROLLING A VOLTAGE UNBALANCE IN A LOW-VOLTAGE DIRECT CURRENT DISTRIBUTION SYSTEM

摘要

A system for controlling voltage unbalance in a direct current distribution system includes a measurement processor configured to measure a positive load current, and a negative load current at a first load point, including a first load connected to a positive line and a neutral line and a second load connected to the neutral line and a negative line, and at a second load point in a power distribution system; and a control processor configured to determine whether to activate a first load point switching signal based on the positive and negative load currents at the first and second load points to control the first load point to switch the connections of the first load and the second load between the positive line and the negative line.

1. A system for controlling voltage unbalance in a direct current (DC) distribution system, the system comprising:
a measurement processor configured to measure a positive load current and a negative load current at a first load point, comprising a first load connected to a positive line and a neutral line and a second load connected to the neutral line and a negative line, and at a second load point; and a control processor configured to determine whether to activate a first load point switching signal based on the positive and negative load currents at the first and second load points to control the first load point to switch the connections of the first load and the second load between the positive line and the negative line.
