SYSTEM AND METHOD FOR SENDING VOLTAGE CONTROL OF LINE DROP COMPENSATION CONSIDERING NEUTRAL POTENTIAL IN LOW VOLTAGE DIRECT CURRENT DISTRIBUTION SYSTEM

摘要

A delivery voltage control system for a low-voltage DC distribution system according to embodiments of the present invention includes a measurement unit for measuring a line current and a neutral line current of a low-voltage DC distribution system, a line current measurement value collected in a low-voltage DC distribution system, And the calculated load center point voltage, line equivalent impedance and neutral line equivalent impedance and the measured line current and the calculated load impedance value, And a compensation delivery voltage determination unit for determining the compensation delivery voltage according to the neutral line current. At this time, the optimal delivery voltage estimates are estimates of the delivery voltage that minimizes deviations between each of the direct-under-carriage voltage and terminal acceptor voltage and the nominal voltage specified for the low-voltage DC distribution system.
