摘　　要：电力系统中所有的基础电气量都是基于时间的物理量。因此,介绍了电力系统时钟同步技术的重要性和目前常见电网时钟同步技术的方式,提出了一种利用电网工频分量周期值进行比对的配电终端对时方法。电网的工频分量周期值是实时变化的,且在不同的地点采集计算的工频分量周期值相同。利用这一特点,通过工频分量周期值比对可实现时钟同步的目的。此方法能够进一步提高配电线路上不同配电终端之间的对时精度。All the basic electrical quantities in the power system are physical quantities based on time.This article introduces the importance of power system clock synchronization technology and the current method of power grid clock synchronization technology,and proposes a comparison using the periodic value of the power frequency component of the power grid.Time distribution method of distribution terminal.The period value of the power frequency component of the power grid changes in real time,and the period value of the power frequency component collected and calculated in different locations is the same.Using this feature,the purpose of clock synchronization is achieved by comparing the period value of the power frequency component.This method can further improve the timing accuracy between different distribution terminals on the distribution line.
