A provincial power company-GPS/Beidou clock synchronization intelligent distribution project (to achieve high-precision synchronization of whole-station timing)

A provincial power company has multiple substations under its jurisdiction. The protection devices, measurement and control devices, and monitoring systems in the stations are numerous and widely distributed. The original timing methods are scattered, have no redundancy, and are susceptible to interference, resulting in the time of each system being out of sync, affecting safe and stable operation.

1. Product application: Deploy GPS/Beidou dual-mode outdoor receiving antennas and clock intelligent distribution units to build a station-wide unified timing and intelligent distribution system.

2. Implementation highlights: dual-mode redundancy automatic switching, multi-channel signal output simultaneously, long-distance transmission without attenuation； Centralized monitoring and visualization, and proactive reporting of faults.

1. Product level: The timing accuracy of the whole station reaches microsecond level, synchronous coverage of 100% equipment, no timing interruption, no time drift, and redundant switching <50ms.

2. Customer value: Full site equipment time synchronization is achieved, log reconciliation accuracy is 100%, operation and maintenance costs are reduced by 72%, and system security risks are eliminated.

“The GPS/Beidou synchronized clock intelligent distribution system operates stably and accurately, completely solving the problem of time synchronization among multiple systems in the station and providing strong support for the safe operation of the power grid. ”
