Smart semsing voltage regulating transformer equipment and voltage regulating method thereof

Abstract

A smart sensing voltage regulating transformer equipment and voltage regulating method thereof are provided. The voltage regulating transformer equipment includes a sensing transformer, a shunt converter, a series converter, a feeder voltage sensing end and a series compensation transformer. The sensing transformer receives an input voltage and converts the input voltage to a secondary voltage. The shunt converter is used to stabilize a DC link voltage of the secondary side voltage. The series compensation transformer is connected to the sensing transformer via a feeder to receive a feeder voltage. The series compensation transformer connected to the feeder voltage sensing end. The series converter is configured to perform a voltage swell compensation operation or a voltage drop compensation operation according to a voltage value at the feeder voltage sensing end, the feeder voltage or the DC link voltage.
