Problems solved by technology

Although the existing system realizes the synchronization from the model database to the operation database, there are few considerations for the synchronization of the operation database to the model database. Therefore, during the development and implementation of the substation, the operation data and edit data are often modified. It is easy to cause out-of-synchronization of running data and editing data

Embodiment Construction

[0022] A method for automatically synchronizing polymorphic data in a substation integrated monitoring system includes the following steps:

[0023] 1. Synchronize source data files between multiple computer nodes by establishing a file server.

[0024] Such as figure 1 As shown, the source data of the integrated monitoring system is stored in files. In order to ensure that the source data files of each computer node are always consistent, the integrated monitoring system needs to set up a unique file server. The specific synchronization method includes the following steps:

[0025] (1) When the system starts, the computer node that is started first sets the local computer node as the file server of the integrated monitoring system, and loads the source data file into the running database;

[0026] (2) After other computer nodes are started, first download the source data file from the file server to the local computer node, and then obtain the data of the running database from the ne...

Abstract

The invention relates to an automatic synchronization method of multistate data in an integrated substation monitoring system. The method is technically characterized by including: firstly, allowing for source data file synchronization among multiple computer nodes by means of creating a file server; secondly, allowing a model database to automatically sync to an operational database through a data incremental mechanism; and thirdly, syncing the operational database to the model database by means of table change record real-time loading. The method is reasonable in design, data are kept constantly consistent in the source data files, the operational database and the model database among the computer nodes of the dual-mode integrated system, field engineering efficiency is greatly increased for intelligent substation automation engineering, and maintenance operations are simpler.

Description

Technical field [0001] The invention is applied to the field of intelligent substation automation technology, in particular to an automatic synchronization method for multi-state data in a substation integrated monitoring system. Background technique [0002] With the popularization and use of projects such as "Integrated Substation Monitoring System" and "Remote Review" of the State Grid Corporation of China, it is necessary to establish a substation integrated system platform with multiple comprehensive capabilities at the station control level of the substation to unify the substation The various automation systems inside, the system has multiple functions such as monitoring, telecontrol, substation, gateway, etc. Following this, the data of smart substations is becoming more and more complex. On the one hand, model-based data realizes the standardized application of data and ensures the flexible association of multi-disciplinary data; on the other hand, the correlation and co...
