Abstract

The invention discloses an automatic identification method for dense power transmission channels adaptive to natural disaster types, which includes: obtaining information on power transmission channel units in each geographic grid in the region where the power grid is located; grouping power transmission channel units according to preset grouping rules to obtain The set of transmission channel units for different sets of overhead transmission lines; according to the preset merging rules, the transmission channel units are merged to obtain the set of connected transmission channel sections for different sets of overhead transmission lines; for any type of natural disaster, filter out From the connected transmission channel sections that are valid for natural disaster types in each set of connected transmission channel sections, the effective connected transmission channel section sets that are effective for the corresponding natural disaster types and corresponding to different sets of overhead transmission lines are obtained, and then the output is about the corresponding A collection of dense transmission corridors that are effective for natural disaster types. The present invention can screen effective dense power transmission channels under natural disasters according to the type of natural disasters, and improve the rationality of generating multiple severe fault scenarios under natural disasters.

Description

technical field [0001] The invention relates to the technical field of power system operation scheduling and operation control, in particular to an automatic identification method for dense power transmission channels adaptive to natural disasters. Background technique [0002] With the construction of cross-regional AC-DC hybrid power grids, and limited by the shortage of land resources and the terrain of transmission corridors, the centralized sending and receiving transmission corridors of the sending and receiving end power grids are becoming more and more dense. UHV AC, DC and ultra-high voltage The problem of crossing and crossing high-voltage AC transmission channels and sharing a transmission corridor has become more and more prominent. In some areas, it is even necessary to adopt the erection method of multiple lines on the same pole. Under natural disasters, multiple serious faults, such as simultaneous tripping of multiple circuits and rapid successive tripping of...
