The continuous induced current at the fault point during the internal ground fault of the double circuit line GIL pipe section may cause the pipe gallery to break down. The mechanism and hazards of induced current and voltage in the GIL section of the double circuit line are analyzed. Combining the protection configuration features of check zone and differential zone in the installation of the double-line GIL, the automatic control closing strategy of GIL induced current quick release device is proposed. The method realizes the automatic closing of delayed high speed grounding switch after the circuit breaker cuts off the internal fault of the GIL pipe gallery by discriminating the operation of the line differential protection at the GIL, the operating state of the line and the GIL and the release device position, thereby avoiding manual operation. Aiming at the unsuccessful closing of the release device, the phase selection action results of the check zone protection of the fault line are collected to determine the faulty closing failure condition. The closing failure warning strategy and the closing failure inter-tripping strategy of the healthy line are proposed to reduce risks of GIL breakdown caused by the induced current. And it means to improve the efficiency of the on-site GIL operation and maintenance. The closing failure alarm strategy and the closing failure action strategy of the normal operating line based on the closing failure fault are proposed. According to the proposed closing control strategy and closing failure strategy, automatic control devices are developed and RTDS test is performed. The test results show that the control system can reliably operate under different conditions, and minimize the risk of the induced current breaking through the pipe gallery.
