Problems solved by technology

[0003] As a single basic support module within the system, the traditional real-time database has strong cohesion and can only store and process real-time data within the system, but it is very difficult to share real-time data between systems, forming a real-time data island
Due to the physical heterogeneity of the system and the difference in geographical distribution, to realize the global sharing of real-time data across the system, it is necessary to complete the export, conversion, transmission and import of real-time data. The processing process is extremely complicated and cumbersome. , the amount of real-time data processed in the system will increase geometrically. The traditional real-time database system cohesively processes data and stores data in a centralized manner. Global calculation of the power grid, the technical bottleneck of intelligent dispatching

Abstract

The invention discloses a large-grid distributed real-time database system and a data management method thereof. The system comprises a wide-area distributed real-time database storage system (1), a globally unique identifier analysis and service positioning system (2), a sub-system internal real-time data access system (3) and a distributed service agent (4), wherein the wide-area distributed real-time database storage system is used for storing real-time data in a wide-area distributed environment and efficiently indexing the real-time data by a globally unique identifier; the globally unique identifier analysis and service positioning system is used for analyzing the globally unique identifier and positioning a logical space in which the real-time data is accommodated and a corresponding service agent by using the globally unique identifier; the sub-system internal real-time data access system provides service for the network access of the real-time data in a sub-system on the basis of the wide-area distributed real-time database storage system; and the distributed service agent is connected with the globally unique identifier analysis and service positioning system and the sub-system internal real-time data access system and provides the service for cross-area and cross-system sharing and access of the real-time data. By the invention, the sharing and management of the mass real-time data in the wide-area distributed network environment can be realized.

Description

technical field [0001] The invention relates to a real-time data management technology, in particular to a real-time data management and sharing method and a distributed real-time database system applicable to large power grid wide-area networks, and belongs to the technical field of electric power system control. Background technique [0002] The real-time database system combines the advantages of real-time systems and database systems. It is the core module of the power dispatching automation system. It is responsible for storing model data and managing massive real-time data, while providing efficient data access and management interfaces for the system. [0003] The traditional real-time database, as a single basic support module inside the system, has strong cohesion and can only store and process real-time data inside the system, but it is very difficult to share real-time data between systems, forming real-time data islands. Due to the physical heterogeneity of the s...
