Tree line fault identification method, simulation device, system, computer device and medium

Abstract

The invention discloses a tree line fault identification method, simulation equipment, a system, computer equipment and a medium, and the method comprises the steps: obtaining simulation fault data through the simulation equipment, and enabling the simulation fault data to comprise fault type information, separation speed information and a simulation fault waveform; the fault type information, the separation speed information and the simulated fault waveform information are matched one by one, a line fault waveform is obtained, the line fault waveform is a transmission waveform when an overhead bare conductor has a transmission fault, whether the line fault waveform is matched with the simulated fault waveform or not is judged, and if yes, the fault type information, the separation speed information and the simulated fault waveform are matched. And pushing the fault type information and the separation speed information matched with the simulation fault waveform if the simulation fault waveform is detected, thereby solving the problems that the acquired data set is too small and the fault is difficult to separate because the tree line fault has the characteristics of small grounding current, weak electrical characteristic quantity, difficulty in causing protection action and the like in the existing simulation equipment in the prior art. Therefore, the problem of inaccurate tree line fault identification is solved.

Description

technical field [0001] The invention relates to the technical field of simulation testing, in particular to a treeline fault identification method, simulation equipment, system, computer equipment and medium. Background technique [0002] The distribution lines in suburban and mountainous areas are dominated by overhead bare conductors, and tree line faults account for a high proportion of single-phase grounding faults. As a typical high-resistance grounding fault, tree-line fault has the characteristics of small grounding current, weak electrical characteristics, and not easy to cause protection action. It is one of the most difficult fault types to detect and trace. In the actual operation of the distribution network, only a few extreme scenarios such as wire breakage and tree fall will lead to permanent tree line grounding faults. In most cases, the tree line fault is a transient ground fault caused by the short-term contact with the conductor during the swaying process ...
