The invention relates to a high-voltage current monitoring time synchronization system and a time synchronization method. A collector sends a time synchronization command to each high-voltage current monitoring device; The compensation value includes the time synchronization preparation time of the collector, the time synchronization command frame transmission time of the collector, and the time synchronization response time of the high-voltage current monitoring device. The present invention has undergone theoretical calculation and experimental verification. Under the premise of software and hardware guarantees, the scheme can repeatedly calculate the average value. The average value of the delay time of ΔT is 260uS, which can ensure the dispersion of 45uS. After 260uS of synchronous compensation for time calibration, the dispersion of 45uS meets the deviation requirement of the three-phase current clock less than 100μs. The present invention does not use a professional time service system such as Beidou, but uses an ordinary real-time clock chip, and has low cost, and the time service system is simple and effective.
