Abstract

The invention discloses a method for realizing grid management by using the hierarchical storage database architecture of the power grid. First, according to the natural characteristics of the power grid structure, the project data with the project content as an independent storage body is classified into a hierarchical and regional database Manage, store and transmit project body data in a compressed format; after that, each project body data contains operation management parameters and geographic information data of various power grid elements predefined by the database management system, and the calculation method of project body data association is automatically completed The electrical topology, electrical parameter statistics and geometric parameter calculation required by the project; the invention is based on the grid level and operation management unit, and uses the grid project as the basic storage unit database management structure, and upgrades the traditional GIS system to the grid element as the management granularity. Taking the power grid project as the management granularity, the storage unit of the power grid elements is opened up in the project, which greatly improves the efficiency of data management.

Description

technical field [0001] The invention relates to the technical field of grid management of power grids, in particular to a method for implementing grid management using a grid-level storage database architecture. Background technique [0002] At present, the background databases of power GIS application systems are basically relational databases, such as: Oracle, SQLserver, DB2 and other classic relational database management systems, which are stored in different record tables according to the classification of grid elements. When the data storage scale is small, Efficiency is not a problem. When a large amount of data is formed, the retrieval of project target data will seriously affect the efficiency of the front-end application system. In practical applications, many systems have seriously affected the practical level due to the rapid expansion of the database; grid planning, management and service It is an important concept for the current and future operation and manage...
