Embodiment Construction

[0038] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0039] An embodiment of the present invention provides a graph database-based power grid topology version management tool, such as figure 1 As shown in , the dual-engine mechanism of topology analysis engine and version management engine is adopted, as follows:

[0040] The topology analysis engine is used to construct the static topology structure of the distribution network and capture and analyze the status and incremental change information of the power grid equipment.

[0041] The graph database is used to generate the basic version of the distribution network topology based on the static topology structure of the distribution network, and to generate the line topology version based on the incremental change information.

[0042] The...

Abstract

The invention discloses a grid topology version management tool and method based on a graph database, and the method specifically comprises the steps: inputting an initial power distribution network topology model into the graph database as a basic version, then monitoring the transaction of the power grid topology model, storing the increment information of the transaction, generating the increment change information, and finally, storing the whole network frame model of the power distribution network topology network frame as a version, and providing version playback and version comparison of the power distribution network topology model. According to the invention, feasibility of version management of large-scale power grid real-time topology and continuous storage and management of the power grid real-time topology version are realized.

Description

technical field [0001] The invention relates to the technical field of power grid topology analysis, in particular to a graph database-based power grid topology version management tool and method. Background technique [0002] The real-time topology of the power grid occupies a very important position in the power system, and it is the basis for the overall planning of the power system operation analysis. The real-time topology of power grid can provide the basis for real-time fault analysis of power grid, including fault location, fault isolation and line transfer scheme formulation. The real-time topology of the power grid provides line-to-change relationship query services and provides a basis for load analysis of the power grid under normal and fault conditions. With the continuous evolution of enterprise middle-end technology, the real-time topology of the power grid, as an important public service for power grid enterprises, has gradually become the main basic service...
