Abstract

The invention relates to the technical field of power distribution automation, and discloses a power distribution topology generation method and device based on Beidou ultra-wideband combined positioning. The method includes: firstly, determining positioning information of power distribution units by using a Beidou and ultra wide band combined positioning method; acquiring a physical structure of the power distribution system, and determining a logical topological relation of the power distribution units; and finally, according to the logic topological relation of the power distribution units and the positioning information of the power distribution units, generating a power distribution network logic topological graph. According to the invention, seamless positioning based on the combination of the Beidou positioning technology and the ultra-wideband positioning technology is utilized, and the problem that indoor positioning information cannot be obtained due to the blocking of buildings, obstacles and the like in a power distribution network is solved. The problem of weak indoor positioning signals can be solved by fully utilizing Beidou and ultra-wideband positioning technologies.

Description

technical field [0001] The present application relates to the technical field of distribution automation, and in particular to a distribution topology generation method and device based on Beidou ultra-broadband joint positioning. Background technique [0002] Topology research is the basis and key content of DC distribution system research. Distribution network topology analysis is the basis for power flow calculation, fault calculation, fault section location, fault recovery, and network reconfiguration. As an important part of the power grid, the stable operation of the distribution network directly affects the security of the power grid. The distribution network topology analysis needs to obtain the location information of the power distribution unit. [0003] At present, the positioning technology is blocked by buildings and obstacles, so that many indoor area power distribution units in the distribution network cannot accurately obtain positioning information. Traditi...
