一种基于电网频率值的配电终端对时方法

A Time Synchronization Method of Power Distribution Terminal Based on Grid Frequency Value

介绍了电网中几种时钟同步方式,提出了一种基于电网频率值的配电终端对时方法。电网频率值实时变化,且同一时刻不同地点采集计算的电网频率值相同。根据这一特点,利用电网频率值进行比对,计算时钟偏差,实现了基于电网频率值的配电终端对时目的。

This article introduces several clock synchronization methods in the power grid,and proposes a method of power distribution terminal time synchronization based on grid frequency value.According to the fact that the grid frequency value changes in real time,and the grid frequency values collected and calculated at different locations at the same time are all the same,the clock deviation is calculated by comparing the grid frequency values,and the time synchronization of power distribution terminal based on grid frequency value is realized.
