Abstract

The invention discloses a fault processing method and device for hybrid lines of a power grid. The fault handling method of the grid hybrid line includes: judging whether the grid hybrid line is faulty; if it is judged that the grid hybrid line is faulty, then detecting the fault section of the grid hybrid line; firstly, isolating the faulty section according to The voltage-type line is processed; and then the isolation of the fault zone is processed according to the current-type line. The present invention solves the problem in the related art that the mixed line of the power grid often cannot be dealt with in time and effectively when a fault occurs.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a method and device for handling hybrid line faults in a power grid. Background technique [0002] Traditional distribution lines can be divided into voltage-type lines and current-type lines according to the way of handling accidents. [0003] When an accident occurs on a voltage-type line, rely on the function of the terminal itself to realize fault zone isolation and load transfer in a non-fault zone; when an accident occurs on a current-type line, DAS relies on the fault signal collected from the current-type terminal to make a fault zone judgment by the DAS system. And give the processing plan of the isolation of the fault area and the load transfer of the non-fault area. Since there are fundamental differences in the mechanism of accident handling for voltage-type and current-type lines, when voltage-type switches and current-type switches are mixed on a distribution line, it is...
