Automatic identification system and method for topological relation of power distribution network

Abstract

The invention relates to an automatic identification system and a method for a topological relation of a power distribution network, the system comprise a sensing layer, a data layer and an application layer, the sensing layer deploys an automatic acquisition terminal to perform real-time monitoring and risk early warning and publishes equipment operation data to the data layer, the data layer cleans and converts the data and then publishes the data to the application layer, and after the application layer receives a data result, the related topological relation graphs are exhibited. The automatic acquisition terminal comprises a station-line relationship identification device, a line change relationship identification device, a station-user relationship identification device and a branchrelationship identification device. The method can achieve the automatic recognition of the distribution network topology, especially achieves the real-time recognition of a station-user relation change-over event, employs the TWACS technology as an implementation path, can achieve the real-time and automatic collection and recognition of the distribution network topology information, and improvesthe management efficiency and development quality of the distribution network.

Description

technical field [0001] The invention relates to the professional field of electric power system automation, in particular to an automatic identification system and method for distribution network topological relationship. Background technique [0002] The distribution network is an important foundation of the Energy Internet and a key foothold for serving the society and people's livelihood. State Grid Corporation strives to build a first-class modern distribution network with high reliability, friendly interaction, and cost-effectiveness. The investment is constantly increasing and the management requirements are constantly improving. The distribution network has a wide range of equipment points, small projects, and short construction periods. Limited by traditional management ideas and methods, the phenomenon of "emphasizing construction and ignoring planning" is more common. Distribution network project management is scattered, professional coordination is insufficient, ...

Problems solved by technology

Due to the vast coverage of the power network, the complex structure of the power system, and the huge number of businesses involved, the work of distribution network operation, deployment, and integration relies heavily on manual on-site inspections, lacks effective means for verification and identification, and lacks a complete and accurate source-network-load full-scale topology Graphics, intelligence and automation need to be improved
