摘      要：A new adaptive single-pole autoreclosure technique based on the magnitude of fault point voltage is *** fault phase tripping,the fault point voltage of transient faults is essentially different from that of permanent faults,so the magnitude of fault point voltage is used to distinguish fault *** point voltage can be calculated through uniform transmission line *** that fault point voltage changes with fault location and transition resistance,a concept of real-time action voltage setting is put *** technique solves the problem that criterions based on terminal voltage could be easily affected by inductive coupling voltage and transition *** results show that the method is reliable.
