Key Technologies of Multi-active data synchronization for Dispatch and Control System

Based on the “physical distribution and logical integration” architecture of new generation power grid dispatching and control system, with requirements of the crossterminal display, cross-center transparent access and multicenter business collaboration, it is necessary to develop a technical framework of data synchronization based on global analysis and decision. Through unified data synchronization, distributed transactions and data recovery and other functions to achieve multi-center data consistency, improve the centralized management of data in the control system. Finally, through the test and live demonstration, data synchronization function of multi-center was verified.
