With the continuous advancement of China's smart grid construction process, it is necessary to ensure that all kinds of power equipment and automation systems operate at the same reference time. Therefore, it is the current main goal to ensure reliable, stable and accurate timing of the timing system. Aiming at the current problems, this paper proposes a high-precision synchronous clock timing scheme based on multi-source timing, which provides timing signals through the Beidou clock and GPS clock under normal conditions, and performs the main timing for the reliability of the timing signals o...
