Method for calculating line topology based on power line carrier radiation signal intensity distribution characteristics

Abstract

The invention discloses a method for calculating a low-voltage power line branch topological structure relationship based on low-voltage power line carrier communication radiation signal intensity distribution characteristics, which is based on low-voltage power line carrier communication radiation signal intensity acquired by each branch node. The innovativeness of the method is to solve the problem that the topological relation cannot be calculated in a carrier communication radiation signal intensity mode due to interference of low-voltage power line carrier communication carrier signal attenuation characteristics and power line noise characteristics on carrier communication radiation signal data. The method for accurately calculating the affiliated branch of the tail-end electric meteris provided according to the radiation signal distribution characteristics of the intelligent electric meter at the tail end of each branch on each branch node, the connection relationship between the branches is calculated according to the carrier communication radiation signal intensity relationship between the branch nodes, and a low-voltage power line branch topological structure relationshipaccurately drawn based on the connection relationship between the tail-end intelligent electric meter and the branches and the connection relationship between the branches.
