    • Abstract
  • The paper analyzed cause of re-closure failures of power supply line, and introduced a kind of location method which uses fault information and protection information to synthetically judge line fault. The method is not only applicable to fault protection re-closure failures of 220 kV line, but also can quickly determine line, equipment and fault point by collecting corresponding fault to make the quantity analysis when the power supply system happened other protection re-closure failures.
