Embodiment Construction

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] In order to solve the data collection problem of the power grid database system and the centralized storage and fast query of massive data, this embodiment adopts the HBase-based centralized storage technology solution for the power grid historical data, which mainly consists of the telemetry data collection definition module, the telemetry data collection module and the telemetry data collection module. Composition of storage modules.

[0029] The telemetry data acquisition definition module is deployed in the data center system. It first obtains the network-wide telemetry data information from the data center system relational database, including the unique ID, telemetry name, and application, and then reads the configured data source information in the data center system. Including the data source number, data source name, and finally provide a graphi...

Abstract

The invention discloses an HBase-based centralized power grid history data storage method, and belongs to the technical field of electric power system databases. The method comprises a telemetering data acquisition definition step of determining a telemetering data source and a data acquisition period, a telemetering data acquisition step of extracting history data from the appointed data source according to the period so as to form a history data file and realize uniform collection of telemetering history data, and a telemetering data storage step of storing the extracted history data into anHBase database to realize centralized storage of the telemetering history data. According to the method, an automatic distribution collection function of history data in the whole network range is realized, and storage problems in mass history data sets are solved on the basis of characteristics of the HBase database; and compared with the traditional relational database-based history data storage, the method has more stable writing and query performance under the premise of a million-level data size, and provides data basis for subsequent history data-based deep data application.

Description

technical field [0001] The invention belongs to the technical field of electric power system databases, and more precisely, the invention relates to a centralized storage method for historical data of power grids based on HBase. Background technique [0002] With the development of UHV large power grids, the operation of interconnected grids and the popularization and application of smart grid technologies have put forward higher requirements for dispatching operation management and the comprehensive application of power grid operation data, dispatching centers at all levels have carried out research work on related data centers , including model data centers, operational data centers, and real-time data centers. Among them, the operation of the data center needs to manage the collection, storage and query of the historical data and alarm data of the entire network. Therefore, the operation of the data center first needs to solve the problem of data collection, and then solv...
