FULL-COMPENSATION ARC SUPPRESSION SYSTEM AND METHOD BASED ON ADJUSTABLE REACTANCE

WIPO Patent Application WO/2024/027163

A1

Provided in the present application are a full-compensation arc suppression system and method based on adjustable reactance. The arc suppression system comprises a first contactor, a second contactor, a third contactor, a first adjustable reactor, a second adjustable reactor, and a line selection and arc suppression apparatus. A three-phase voltage of a bus, a zero sequence voltage and a zero sequence current are inputted into an input end of the line selection and arc suppression apparatus; an output end of the line selection and arc suppression apparatus is connected to the first contactor, the second contactor and the third contactor, and is used for controlling the switching on and off of the first contactor, the second contactor and the third contactor; and the output end is connected to the first adjustable reactor and the second adjustable reactor, and is used for controlling voltage division coefficients of the first adjustable reactor and the second adjustable reactor, such that the arc suppression system outputs a designated amplitude and phase of a voltage.
