Abstract

The invention discloses a low-voltage distribution topology identification method and system, which relate to the technical field of low-voltage distribution topology identification. The location information of the smart meter is used to delineate the geographical location of the smart meter and the transformer in combination with the maximum power supply radius of the transformer, and the smart meter and the transformer are established. The correlation matrix between transformers, and then establish the smart meter description linked list and the transformer description linked list. The smart meter description linked list describes the smart meter and its related transformer set, including a strong related transformer set and a weak related transformer set. The transformer description linked list describes the transformer and its related The collection of smart meters includes a collection of strongly correlated smart meters and a collection of weakly correlated smart meters. According to the voltage correlation between smart meters and transformers, the household transformer relationship can be determined, which can not only overcome the problem of misjudgment caused by simply using electrical quantity identification, but also does not require additional Adding equipment will not cause interference to the power grid and will not increase the difficulty of construction.

Description

Technical field [0001] The present invention relates to the field of low-voltage distribution topology identification technology, in particular to a low-voltage distribution topology identification method and system. Background [0002] Low-voltage distribution topology identification refers to the connection relationship between the branches from the emergence of the low-voltage side of the distribution transformer to the various user access points. The correct topological relationship is the premise of carrying out lean line loss management and promoting line loss governance in Taiwan areas, and is an effective starting point for realizing the quality and efficiency of power supply enterprises. [0003] The traditional household change relationship information is entered manually, due to imperfect information, untimely update, there are often household change relationship errors, which seriously hinders the lean management of the low-voltage platform area, therefore, it is imp...
