Example Embodiment

[0022] An automatic synchronization method for polymorphic data in a substation integrated monitoring system, comprising the following steps:

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

[0024] like figure 1 As shown, the source data of the integrated monitoring system is stored in the form of 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, then obtain the data of the ru...

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 technical field of intelligent substation automation, in particular to an automatic synchronization method for multi-state data in an integrated monitoring system of a substation. Background technique [0002] With the popularization and use of projects such as "substation integrated monitoring system" and "remote access" of the State Grid Corporation of China, a substation integrated system platform with multiple comprehensive capabilities needs to be established at the substation control level to unify substations Various automation systems within the system, the system also has multiple functions such as monitoring, telecontrol, substations, and gateways. What follows is that 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 relevance and...
