Embodiment Construction

[0023] The invention provides a distributed data storage method and system, which are used to solve the problem of poor real-time performance of data call due to large amount and variety of data.

[0024] To achieve the above object, the technical solution provided by the invention is:

[0025] A distributed data storage method, setting a first database and a second database in the data storage area, when receiving data:

[0026] If the data is data expressing the relationship between the data, storing the data in the first database;

[0027] If the frequency of data calling is greater than the set frequency value, store the data in the buffer;

[0028] If the data is real-time data, the data is stored in the second database database.

[0029] The technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0030] Method example:

[0031] This embodiment provides a distributed data storage method, which is suitable...

Abstract

The present invention provides a distributed data storage method and system. The storage method comprises a step of setting a first database and a second database in a data storage area and storing data indicating a relationship between data into the first database, a step of storing the data into a buffer if the frequency of data calling is greater than a set frequency value, and a step of storing the data into the second database if the data is real-time data. According to the technical scheme provided by the invention, the distributed storage of the data is carried out according to the typeof the data, the data with a calling frequency is stored in the buffer, the calling of the data is facilitated, the calling rate of the commonly used data is accelerated, and the problem of poor real-time performance of data calling caused by a large amount and multiple types of the data is solved.

Description

technical field [0001] The invention belongs to the technical field of power system data storage, and in particular relates to a distributed data storage method and system. Background technique [0002] Traditionally, the power system is divided into three major components: generation, transmission, and distribution. The electric energy generated by the power generation system is transported through the power transmission system, and finally distributed to various users by the power distribution system. Generally, the section of the power system from the outlet of the step-down distribution substation (high-voltage distribution substation) to the user end is called the power distribution system. The power distribution system is a power network system composed of a variety of power distribution equipment (or components) and power distribution facilities that transforms voltage and directly distributes power to end users. [0003] The SCADA system, that is, the data acquisit...
