A method and device for automatic identification of network topology in a low-voltage distribution station area

Abstract

The present invention provides a method and device for automatically identifying the network topology of a low-voltage distribution station area. The method includes: step 1, judging whether branch boxes are included in the network topology of the low-voltage distribution station area; step 2, if not branch box, then obtain the first current data collected in the JP cabinet or switch cabinet, and obtain the second current data collected in the meter box; step 3, according to the first current data and the second current data, The network topology structure of the low-voltage distribution station area is obtained through calculation. The device includes: a judgment unit, a data acquisition unit and a topological structure extraction unit. The present invention can realize automatic identification of network topology without introducing too many hardware facilities, saves cost, is easy to realize, convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of network topology identification in the electric power industry, in particular to the field of network topology relationship identification of a low-voltage distribution station area of ​​a power system, and in particular to an automatic identification method and device for a network topology structure of a low-voltage distribution station area. Background technique [0002] With the gradual improvement of the intelligence level of the power grid, higher requirements are put forward for the precise management of the power grid. As a part of the power grid, the power distribution station area will directly affect the power consumption level of users, such as power quality, power supply reliability, operation and maintenance costs. Nowadays, compared with the intelligent level of power transmission and medium-voltage distribution network, the degree of automation of low-voltage distribution network is far fr...

Problems solved by technology

[0004] At present, when intelligently managing low-voltage distribution stations, the figure 1 and figure 2 It can be seen that there is a technical problem in the commonly used network architecture of the existing power grid: the topological relationship between the low-voltage power distribution unit (switch cabinet, JP cabinet) in the station connected to the transformer outlet and the meter box at the next level cannot be known, that is, The network topology relationship of the low-voltage distribution station area is not clear

The system still incorporates many hardware modules, and the operation is relatively complicated
