Multi-heterogeneous Data Synchronization Method for New Generation Substation Monitoring System

Abstract

In principle, the new generation substation monitoring system no longer has duplicate data collection across safety partitions. To avoid information islands between nodes of different safety partitions and to realize efficient interconnection and interoperability of different types of information, this paper proposes a multivariate heterogeneous data synchronization method for the new generation substation monitoring system. Firstly, the overall framework of the structured data synchronization method, synchronization data encapsulation modeling, cache format construction, and subgroup and group packet processing are introduced; secondly, the overall architecture of the unstructured data synchronization method is introduced, including full data updating and difference data updating, and the latter improves the efficiency of data chunking and achieves the incremental synchronization process of the difference by the fast CDC method based on the identification of the local difference; finally, the test validation is carried out based on the actual data for testing and validation. The results show that the multivariate heterogeneous data synchronization methods are 100% correct, and the incremental difference synchronization saves more than 70% of the synchronization time.
