Abstract

The invention relates to a power distribution area monitoring device, a power distribution area topology identification system and a power distribution area topology identification method. The power distribution area monitoring device comprises low-voltage monitoring unit, wherein the low-voltage monitoring units are arranged below the transformer area physical net rack and on the corresponding low-voltage branch lines, and the low-voltage monitoring units are used for collecting and outputting first measurement information; and a power distribution gateway, wherein the power distribution gateway is connected with the power distribution area physical net rack and is connected with each electric energy meter in the power distribution area; the power distribution gateway is connected with each low-voltage monitoring unit and is used for connecting the cloud platform; furthermore, the power distribution gateway can obtain the voltage distribution data of the low-voltage side of the distribution transformer, the monitoring point of the low-voltage monitoring unit and the electric energy meter, and the voltage distribution data which can indicate the cloud platform to carry out correlation analysis to obtain a correlation analysis result, and the low-voltage topology can be corrected according to the correlation analysis result, thereby finally, accurately and stably completing topology identification of the low-voltage power distribution area.

Description

technical field [0001] The present application relates to the technical field of distribution networks, in particular to a monitoring device for a distribution sub-area, a topology identification system and a method for a distribution sub-area. Background technique [0002] The low-voltage distribution area is an end network that directly supplies power to users and is an important part of the power grid. In recent years, with the advancement of smart grid construction, the construction and application of systems such as intelligent terminal monitoring and power consumption information collection in low-voltage distribution areas , It creates favorable conditions for the intelligent and information management of the low-voltage power grid, and greatly improves the reliability and safety of power supply. [0003] However, during the construction of the above-mentioned system, the information management of the power grid equipment below the distribution transformer (hereinafte...
