Performance Measurements on PRC in Frequency Synchronization Network of Power Communication


At present, all the time synchronization systems in substations, power plants and dispatching centers are working on the basis of satellites reference and operate independently. To ensure that the services in each power grid can run safely and stably, it is urgent to establish time synchronization network to meet the requirements of timing reference for various services. The frequency synchronization network is composed of clock node equipment and synchronous clocks. The clock node equipment is divided into three classes according to the performance index. Among them the first class clock mainly includes Primary Reference Clock (PRC) and Local Primary Reference (LPR).

We can provide a comprehensive test solution to verify the synchronization performance of PRC.
