Analysis Of Distribution Network Outrage Region Based On Graph Database
There is an internal relationship between the power network topology and graph database and electrical components and their connection lines can be stored in graph database in the form of vertices and edges. The paper proposes a new method based on graph database to analyse power network outage region. The connection between electrical equipments is abstracted into vertexes connected by a certain edge. Firstly, compared with traditional power flow algorithm based on matrix calculation, the advantage of calculation based on graph database is analyzed. Then the paper introduces an advanced graph product, namely GraphSQL, and its remarkable ability to deal with power topology data. Furthermore, according to outage analysis business, this paper builds a graph model to search potential components which are influenced by power off nodes and its analysis process is also be showed. Finally, based on a group of topology data of an actual distribution network, query result of graph model is presented, and its short query time also meets pratical requirement.
