This article analyzed the causes of intelligent substation merging unit sampling synchronization or time delay. The effects of sampling synchronization or time delay on protective device were verified through practical case and field application, and the comprehensive errors of the collecting system were reached. It also puts forward methods and suggestions for the design, production, testing and operation of merging unit in smart station.
