Description

technical field [0001] The invention belongs to the technical field of power grid dispatching, and in particular relates to a small-current grounding automatic circuit pulling control device for distribution network based on machine learning. Background technique [0002] At present, the grounding method of my country's 10kV power system mainly adopts the small current grounding method. In the case of single-phase grounding on the 10kV line, because there is no short-circuit current in theory, the protection cannot operate, and it can continue to run for 2 hours according to the regulations. During this period, dispatchers need to pull the 10kV lines one by one to determine the grounded line. Traditionally, dispatchers mainly determine the order of road pulling operations through manual experience, and use the remote control function of the dispatch automation system to manually perform road pulling operations. When determining the order of pulling the lines, on the one ha...

Problems solved by technology

When determining the order of pulling the lines, on the one hand, it is necessary to determine the grounding line as quickly as possible; Electricity, historical grounding conditions and many other factors, it is difficult to quickly optimize the routing sequence by relying on the experience of dispatchers alone

At the same time, for the sake of safety when performing remote control pulling operation, traditionally, the pulling operation is mainly carried out manually one by one, resulting in a long duration of grounding and serious harm to the safe operation of the power grid.
