Automatic identification system of area topology

Abstract

The invention discloses an automatic identification system of area topology. The system comprises a master station, a concentrator and one or more identification terminals; the master station is used for periodically generating an area topology identification instruction according to an area topology identification strategy, obtaining area topology logic relationship information generated by the concentrator and drawing an area topology graph according to the area topology logic relationship information; the concentrator is used for releasing an identification terminal control command according to the area topology identification instruction periodically generated by the master station, identifying an identification signal generated by the identification terminal and generating the area topology logic relationship information according to the identification signal; and the identification terminal is used for sampling a signal on a power line according to the identification terminal control command released by the concentrator, performing load carrier signal demodulation and operation processing and generating the identification signal. By adoption of the automatic identification system, the area topology identification precision can be guaranteed, and the area topology graph is obtained accurately; and the condition of the line can be periodically checked, and the manpower investment of operation and maintenance work of the power grid is reduced.

Description

technical field

[0001] The invention relates to the technical field of smart grids, in particular to an automatic identification system for station topology. Background technique

[0002] In recent years, various power grid companies have invested a lot of energy, material resources, and manpower in the construction of smart grids. Significant progress has been made in the construction of smart grids. The basic data of smart grids are used for big data analysis to solve the problems of grid safety, emergency repairs, and line loss. Practical issues such as management have also begun to bear fruit.

[0003] At this stage, using the existing collection system of the smart grid to solve grid security, fault repair, line loss management, and anti-stealing through big data analysis has a certain effect. The main problem is that although the measurement of the existing collection system for smart grid construction The terminal has a wealth of functions such as electrical paramete...
