Abstract

A thyristor flexible control strategy based on zero sequence current update control is proposed to solve the problem of flexible arc suppression of single-phase faults in distribution networks. Based on the innovation graph theory, the zero sequence current innovation characteristics before and after feeder fault are analyzed, and the zero-sequence current innovation line selection method for single-phase fault of distribution network is proposed. A master-slave arc suppression coil compensation device is improved, and a control strategy of arc suppression coil is proposed with the amplitude of zero-sequence current innovation as the trigger condition. ADPSS simulation program is used to verify the effectiveness of the method, which provides a theoretical basis for the flexible arc suppression method of single-phase ground fault in distribution network.
