An intelligent distributed protection and self-healing method with reclosing function

Abstract

The present invention discloses an intelligent distributed protection and self-healing method with a reclosing function, which realizes the discrimination of fault types by adding a switch reclosing function, and implements different fault isolation and power supply restoration processes for transient faults and permanent faults: when a transient fault occurs in a line in a region, the fault is automatically isolated and the power supply of the entire line is restored, and protection can be continued without manual operation; when a permanent fault occurs, the fault is automatically isolated and the power supply of the non-fault area is restored, and protection can be continued after the fault is manually eliminated. The intelligent distributed protection and self-healing processing scheme for transient faults of the present invention does not require manual participation, and improves the automation level of fault processing and self-healing of the distribution network.
