| Abstract: | Unified clock synchronization system among all substations and dispatching centers of all levels is badly needed for smart grid to develop.A precise clock synchronization system in the whole network based on IEEE 1588 standard is an effective way to build up this synchronization mechanics.Its principle and features of this precise synchronization system are presented,as well as the reason why this system is necessary for network.The process of synchronization and prolonging calculation are proposed,the key hardwares and basic software framework of synchronization system based on IEEE 1588 standard are analyzed,together with its test method.The test result shows the accuracy of this system. |
