Abstract

A method for fast topology analysis of a power network based on a graph database, comprising the following steps: numbering nodes, switches and branches in the power network wiring diagram; Describe the terminal numbers of the power network to form a topology matrix; establish a Neo4j-CIM model, and map the power topology matrix to the Neo4j-CIM model; perform topology analysis on the power network, form a power network topology map, and realize visualization. The invention establishes a standard and open power system information model, promotes interoperability, reduces production and maintenance costs, and greatly improves the speed and accuracy of power network topology analysis.

Description

technical field [0001] The invention relates to the technical field of design of power network topology logic diagrams, in particular to a method for fast topology analysis of power networks based on graph databases. Background technique [0002] With the continuous advancement of computer technology and communication technology, the power system has an urgent need for information sharing and application integration. For this reason, it is particularly important to promote the interoperability between applications, reduce production and maintenance costs, and improve the real-time performance of the system by establishing a standard and open power system information model. [0003] The International Electrotechnical Commission (IEC) has formulated some standards, including the IEC 61970 standard public information model applied to the dispatch center EMS (Energy Management System). Most of the existing power network topology analysis methods are based on the relational data...
