Power grid panoramic modeling method and system

Abstract

The embodiment of the invention provides a power grid panoramic modeling method and system, and the method comprises the steps: obtaining a core model and an application system model of the power grid, expanding the application system model on the outer side of the core model based on the general standard of a power system by taking the core model as a backbone, and constructing the panoramic model of the power grid. Through constructing the panoramic model of the power grid, the unified maintenance and management of the power grid model are realized, and the information sharing of each application system is realized. Moreover, by adopting the general standard of the power system, the device difference of different manufacturers can be avoided, and a data basis is provided for the intelligent analysis of power grid fault diagnosis.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent management and control of power grid relay protection, and more specifically, to a method and system for modeling a panorama of a power grid. Background technique [0002] At present, there are many independent application systems for the relay protection of power grid, such as protection information system, online protection setting value checking system, etc. These independent application systems play an important role in the operation monitoring and management of relay protection, accident analysis and treatment. However, most of these application systems are designed separately for different business requirements, which makes the application system poor in integrity, unreasonable in structure, and difficult to flexibly expand the system. These application systems generally have the following problems: [0003] (1) Each application system is modeled separately and...

Problems solved by technology

However, most of these application systems are designed separately for different business requirements, which makes the application system poor in integrity, unreasonable in structure, and difficult to flexibly expand the system. These application systems generally have the following problems:

[0003] (1) Each application system is modeled separately and maintained independently, without forming a unified power grid model, which cannot guarantee the consistency of the model, and cannot realize the sharing of information between models;

[0004] (2) Each application system involves multiple manufacturers, resulting in poor coordination and interoperability of the application system, difficulty in information sharing, and heavy maintenance tasks, which cannot meet the needs of the continuous development of the power grid;

[0005] (3) Each application system lacks a unified platform support, and there is no unified specification for graphics and databases. It is difficult to integrate horizontally and vertically through the system, and the interface with external systems is complicated.
