Problems solved by technology

[0002] The real-time data collected by the distribution automation system has time-series characteristics, and the distribution automation system has a large number of collection points. The collection points of a medium-scale system can reach 300,000-500,000, and the collection points of a large-scale system can reach 500,000-1 million. , the annual data storage scale reaches TB level, and the current commonly used relational databases such as ORACLE, DB2, and SYBASE cannot fully meet the needs of the distribution automation system for storing historical operating data

Embodiment Construction

[0009] see figure 1 , an application method of a dynamic information database in a distribution automation system consists of the following steps:

[0010] 1. Configure the historical database: configure the computer nodes where the historical database service program runs, the logical disk partitions used for historical data storage, the maximum number of collection points, IP addresses, port numbers, naming services, etc.

[0011] 2. Start the history library service program: start the history library service program on the configured computer nodes.

[0012] 3. The history library provides database management and data query services to the outside world: the server detects the client's requests for database connection, management, and query on the network.

[0013] 4. The client connects to the historical library service program: start the client program on the client computer node, input the IP address, port number and naming service of the server, and connect.

Abstract

An application method of a dynamic information database in a distribution automation system comprises the following steps: a history database is configured, a history database service program is started, external database management and data inquiry services are provided by the history database, a Client is connected with the historical database service program, the history database is managed by the client, history data is written by the client, the history data is compressed, optimized and stored through the historical database service program, the history data is read by the Client according to time conditions, and the history data is inquired and returned through an optimized query algorithm by the historical database service program. According to the time characteristics of the stored data, lossless compression or pretreatment compression is carried out to the data, and optimized storage and access strategies are adopted to obviously improve the efficiency of the distribution automation system.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an application method of a dynamic information database in a power distribution automation system. Background technique [0002] The real-time data collected by the distribution automation system has the characteristics of time series, and the distribution automation system has a large number of collection points. The collection points of a medium-scale system can reach 300,000-500,000, and the collection points of a large-scale system can reach 500,000-1 million. , the annual data storage scale reaches TB level, and the current commonly used relational databases such as ORACLE, DB2, and SYBASE cannot fully meet the needs of the distribution automation system for storing historical operating data. With the continuous improvement of the distribution automation level, it is required that the real-time operation data should no longer be stored by periodic ...
