A Multimodality Information Synchronization Scheme for a Multisource Information System in the Electric Grid

Abstract

Amultisource and heterogeneous database is an important problem that disturbs the use of the electric power information system. .e existing database synchronization scheme has some problems in practical applications, such as high resource loss and poor portability. .is paper presents a high-efficiency database synchronization scheme for the electric power information system. .e database is monitored, and its changes are captured by the shadow table and trigger method. .us, data could be exchanged in trusted networks and nontrusted networks. In addition, a predetermined strategy is used to avoid data conflicts and ensure consistency and reliability of data synchronization. .e above method is applied in the protection system of power networks. .e results show that the synchronization scheme can effectively ensure the security of the system and has higher synchronization efficiency.
