    摘要: Provided are a novel distribution automation system and its voltage control method, which can supply a stable voltage to a user by properly adjusting the settings of a control device so as to compensate for reactive power at each load terminal. The voltage control method includes: a first step of modeling a distribution system in the form of a distribution load based on constants of four terminals according to the connection type of each node and a distribution line, which constitute the distribution system; a second step of determining a formula for estimating the magnitude of a voltage at a node from a current value of an adjacent node; a third step of determining an objective function including the magnitude of the voltage, calculated through the formula determined in the second step, and a control variable for controlling the magnitude of the voltage; and a fourth step of calculating a value of the control variable to allow the determined objective function to have a minimum value and applying the calculated value to each voltage control device provided in the distribution system.
