| Abstract: | It is difficult to judge the fault point of dead-zone fault,and it is also a difficult point for power dispatcher in fault treatment.If faults in the dead zone are not removed quickly,it will seriously threaten the security and stability of power system operation.In the paper,some common dead-zone fault phenomena were analyzed briefly.And the dead-zone fault treatments and preventive measures were proposed by examples. |
