Power distribution network data real-time synchronization method and system

The invention discloses a power distribution network data real-time synchronization method and system. The method comprises the following steps: a main server detects whether connection of a database or a side server is abnormal or not; if the database connection is normal, the main server selects a corresponding data synchronization mode according to the synchronization mode configuration of the database, and notifies the side server to perform data synchronization; if the database connection is abnormal, the main server packages and compresses all database files and sends the files to the side server, so that the side server receives the corresponding files and unfolds the files to the corresponding databases. According to the invention, the real-time data is classified, so that the performance requirement of the power distribution system on the real-time data is ensured, the influence of data updating equivalence on other functions under the condition of large data volume is minimum, and the data can be sa
