A real-time data storage system for grid operation

Abstract

The invention discloses a power grid real-time operation data storage system, which includes a data extraction unit, a data resolution unit, a conversion rule library, a management unit, a processor, a display unit, a main storage unit, a data transfer module, an auxiliary memory unit, a data Extraction unit and transfer rule library; the present invention uses the data extraction unit to collect power grid operation information, and then uses the data resolution unit to perform data conversion on the power grid operation information to obtain power grid operation data with first-level marks and second-level marks; specifically In order to use the configuration corresponding to the power grid operation data, the configuration is calculated by the data value within the date. Storing the same configuration data together can distinguish the data well, and the calculation method and classification method are simple.

Description

technical field [0001] The invention belongs to the field of data storage, and relates to real-time operation data of a power grid, in particular to a storage system for real-time operation data of a power grid. Background technique [0002] The patent document with the announcement number CN103116595B discloses a method for implementing distributed storage of SCADA historical data facing the power grid. The front-end server collects power data in real time, assembles the data into messages, and sends them to the bus in the form of messages; The application servers read the subscribed messages, and put the parsed data into the real-time database; the data in the real-time database is constantly refreshed, and the data of different business types are stored in batches in the open source distributed database at different sampling frequencies. The present invention adopts the distributed storage of massive scada historical data, has the advantages of fast query and analysis cap...

Problems solved by technology

[0003] However, when storing the data obtained by SCADA, only distributed storage is considered. However, there is a lack of an effective data differentiation method to distinguish the data itself and allocate different storage objects accordingly. storage; at the same time, it can make independent judgments on some important files, and form a storage backup for important files, so as to avoid the situation that the storage files are damaged in some cases but there is no targeted backup. The most existing one is to perform a comprehensive backup, but This requires a lot of storage space; to solve this technical problem, a solution is provided
