Abstract

This application discloses a historical data storage method, reading and writing method, storage device and equipment, which store a group of measurements belonging to the same power system resource type and with the same measurement value acquisition period in a historical data table , the measurement history values ​​of the same power system resource object collected at the same time point are located in the same record, so that when storing multiple measurement value data of the same power system resource object, it is not necessary to repeatedly write the time value, reducing the The storage requirement effectively improves the storage efficiency of the grid CIM model measurement historical data; when reading, multiple measurement values ​​at a specified time can be obtained at one time, which improves the access efficiency; solves the storage of the existing measurement historical data This method has technical problems of low storage efficiency and low data access efficiency.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a historical data storage method, reading and writing method, storage device and equipment. Background technique [0002] With the continuous development of computer technology and the continuous improvement of informatization, the amount of data is increasing rapidly, and the storage and application of massive data are also flourishing, and the reference of big data is becoming more and more extensive. [0003] During the operation of the power detection system, a large amount of measurement data will be generated, that is, the data collected by sensors to monitor the operation of various power equipment, and the public information model of the power system in the energy management system interface standard formulated by the International Electrotechnical Commission (IEC) The measurement model (CIM, Common Information Model) models this, and provides a hist...
