Embodiment Construction
[0051] The present invention will be described in further detail below through specific implementation examples in conjunction with the accompanying drawings.
[0052] Considering that the current hybrid line faults of voltage-type lines and current-type lines cannot be accurately judged and repaired, an embodiment of the present invention provides a hybrid line fault processing method, including:
[0053] Update the online library status of the corresponding device according to the terminal signal status, and perform charging and power-off coloring;
[0054] According to the online library status of the exit switch and the charging and power-off coloring of the voltage-type automatic switch, the hybrid line fault judgment and accident interval judgment are carried out;
[0055] Isolate the accident zone;
[0056] Determine the load transfer strategy;
[0057] According to the action characteristics of the voltage type switch and the current type switch, the operation ticket...

The field of power grid fault processing of the present invention, in particular, relates to a hybrid line fault processing method and device. The hybrid line fault handling method includes: updating the online library status of the corresponding equipment according to the terminal signal status, and performing charging and power failure coloring; judging the hybrid line fault and accident detection according to the online library status of the outlet switch and the charging and power failure coloring of the voltage type automatic switch Interval judgment; Isolate the accident interval; Determine the load transfer strategy; According to the action characteristics of the voltage-type switch and the current-type switch, edit the combination of the voltage-type switch operation ticket and the current-type switch operation ticket in the load transfer strategy to form a new operation ticket; perform troubleshooting according to the new operation ticket. The processing device executes the processing method described above. The invention can solve the problem of fault handling when a voltage type switch and a current type switch are mixed on a distribution line.
Description
technical field [0001] The field of power grid fault processing of the present invention, in particular, relates to a hybrid line fault processing method and device. Background technique [0002] Traditional power 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 the isolation of the accident area and load transfer in the non-accident area; when an accident occurs on the current-type line, DAS relies on the fault signal collected from the current-type terminal to make the judgment of the accident area by the DAS system. And give the treatment plan of the isolation of the accident area and the load transfer of the non-accident area. [0004] Since there are fundamental differences in the mechanism of accident handling for voltage-type and current-type lines, when voltage-type switches and cu...
