Distributed storage system for storing real-time operation data of power grid

Abstract

The invention discloses a distributed storage system for storing real-time operation data of a power grid. The distributed storage system comprises a data acquisition unit, a data analysis unit, a data division unit, a controller, a display unit, a management unit, a data following unit and a storage end. According to the invention, the data acquisition unit acquires power grid operation data; thepower grid operation data is classified by means of a data analysis unit to obtain classified operation data; order analysis is carried out on the classified operation data by means of a data division unit to obtain three influence factors, namely a content occupation value Sij, a span duration Tij and a repeated value Zij, corresponding to the classified operation data, and an odd value Qij ofthe corresponding classified operation data is calculated according to the three influence factors; then, by means of a controller and a corresponding rule, ranking values are distributed to the classified operation data according to the odd values Qij, and then the corresponding classified operation data are stored and distributed according to the ranking values by means of an identification unloading unit.

Description

technical field [0001] The invention belongs to the field of distributed storage of grid operation data, and relates to a distributed storage technology, in particular to a distributed storage system for storing real-time grid operation data. 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...

Problems solved by technology

[0003] However, when the patent processes the historical data, it does not combine the characteristics of the data itself, but only stores the data of different business types into the open source distributed database at different sampling frequencies, and lacks a comprehensive consideration of the characteristics of the data itself; and it does not highlight The importance of the data itself; to address this technical issue, a solution is now provided
