Abstract

The invention discloses a method for realizing a real-time database for a miniature power grid intelligent terminal. The method comprises the following steps of: mapping data sheets, regions and records forming a real-time database to internal storages of the miniature power grid intelligent terminal in a file mapping mode, and forming a database entity; and storing the head address of a tablespace and the address of a record pointer in a corresponding B+ tree. The real-time database generated according to the method can operate in the miniature power grid intelligent terminal which is only provided with an embedded processor and few internal storages; the data access of the real-time database can be kept in a microsecond speed; and complex and dynamic variation data can be stored in the real-time database.

Description

technical field

[0001] The invention relates to a method for realizing a real-time database, in particular to a method for realizing a real-time database by using a file mapping method to generate a database entity in view of the technical characteristics of an intelligent terminal of a micro-grid, and belongs to the technical field of a smart grid. Background technique

[0002] Micro-grid, also known as micro-grid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads, monitoring and protection devices. , protection and management of autonomous systems. Micro-grids can operate in parallel with the large grid or in isolation, and are an important part of the smart grid.

[0003] Microgrids have a dual role. For the large power grid, as a smart load that can be changed in size, the micro-grid provides a dispatchable load for the local power system, can respond within...
