Explore of the Electricity Information Acquisition System´s Clock Synchronization Method

According to such problems as acquisition terminal and smart meter´s real-time deviation is large which has lead to TOU power price and ladder power price policy difficult to successfully implement in electricity information acquisition system, this paper has applied GPS clock synchronization technology and PTP clock synchronization technology in electricity information acquisition system´s simulation platform. It has proposed a microsecond accuracy clock synchronization methods to ensure acquisition terminal and smart meter´s clock is accurate, reliable and unity based on master station, acquisition terminals and smart meter´s three-tiered clock synchronization mechanism.
