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

Embodiment Construction

[0053] Such as figure 1 As shown, a power grid real-time operation data storage system includes a data extraction unit, a data resolution unit, a conversion rule base, a management unit, a processor, a display unit, a main storage unit, a data transfer module, an auxiliary memory unit, and a data retrieval unit. Cell and transit rule base;

[0054] Wherein, the data extraction unit is used to collect power grid operation information by means of the pre-acquisition subsystem in the SCADA system. The power grid operation information includes power grid operation data, and the corresponding data size and data time, and the data time is the time generated by the data. time; the power grid operation data is the data generated during the actual operation of the power supply network, which may specifically include real-time data of the power grid, power grid parameter data, power generation and load data, historical data, and analyzed and calculated data; the data extraction unit use...

Abstract

The invention discloses a power grid real-time operation data storage system. The system comprises a data extraction unit, a data conversion unit, a conversion rule base, a management unit, a processor, a display unit, a main storage unit, a data transfer module, an auxiliary memory unit, a data call unit and a transfer rule base. The data extraction unit is used for collecting power grid operation information, and then the data conversion unit is used for carrying out data conversion on the power grid operation information to obtain power grid operation data with a first-layer mark and a second-layer mark; specifically, by means of configuration corresponding to power grid operation data, the configuration is calculated through data values within dates, data with the same configuration isstored in one block, the data can be well distinguished, and the calculation mode and the classification mode 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...
