Line-transformer relation identification method

Abstract

The invention discloses a line-transformer relation identification method. The method comprises the steps that a line-transformer relation identification terminal logs in a master station through a 4G signal; the master station sends an identification command to a corresponding line-transformer terminal through a 4G signal; after receiving the command, the line-transformer terminal sends an identification signal to a 10kV power line; after receiving the power line signal, a line-transformer relation analyzer reports the power line signal to the master station through a 4G signal; the master station determines the line-transformer relation through the corresponding relation between the line-transformer terminal and the line-transformer relation analyzer. The line-transformer relation is identified through cooperation among the line-transformer terminal, the line-transformer relation analyzer and the master station, the line-transformer terminal is internally provided with a GPRS module with a GPS positioning function, the master station can obtain the position information of the line-transformer terminal to determine the position of the corresponding transformer, the line-transformer terminal is further provided with a second GPRS module at the same time, when signals at the installation position of the line-transformer terminal are insufficient, the second GPRS module can be arranged at the position with sufficient signals through a network cable, so that the master station obtains the position information of the transformer, and the operation and maintenance difficulty of an electric power company is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of line-change relationship recognition, in particular to a line-change relationship recognition method with a GPS positioning function. Background technique [0002] With the continuous development of my country's power supply and distribution technology, more and more transformers are connected to the power distribution lines, which increases the complexity of 10kV. Different terrains lead to complex and diverse routing methods of medium-voltage distribution lines. Lines often need to be modified and loads switched, so it is impossible to confirm the ownership relationship between transformers and lines in real time. At the same time, due to the transformation of the line, the topological relationship has changed, making it impossible to confirm the specific location of the transformer, which has brought a lot of inconvenience to the operation and maintenance of the power companies.
