During the operation of the power system, the operating status of the power grid changes rapidly, and the power grid Scheduling implements hierarchical and multi-level management, and the dispatch management center is far away from the site. In order to ensure the safe and economical operation of the power grid, various automation devices based on computer technology and communication technology are widely used, such as dispatch automation systems, fault recording devices, microcomputer relay protection devices, and event sequence recording devices.
Recording device, substation computer monitoring system, electric energy billing system, thermal power plant unit automatic control system, lightning positioning system
and control devices for coal transportation, ash removal, desulfurization, etc. With the improvement of the automation level of power plants and substations, the power system's requirement for a unified clock for the entire station is becoming more and more urgent. With a unified clock, it is possible to realize the operation of all systems in the entire station under a unified time base
Perform monitoring, and also analyze the cause and development process of the accident through the sequence of each switch action. Therefore, the safe, stable and reliable operation of the power system has further increased the requirements for the unified reference and accuracy of the clock. It has been necessary to establish a unified time synchronization system for the whole station in power plants, substations and dispatch centers of the power system. It seems very urgent and necessary.
In addition, each station often has different devices that need to receive clock synchronization signals. There are many types of interfaces and the number of devices also varies. Therefore, in practical applications, the number of certain types of interfaces of satellite timing devices is often felt. Insufficient or missing certain types of interfaces, the result is that some devices in the entire station cannot achieve clock synchronization, or one or even several additional satellite timing devices need to be added, which is often affected by insufficient funds. Or there are no restrictions such as installation location.
