摘要

同步测量在电力系统的相位测量、故障定位检测等方面具有重要的应用价值。本文介绍了用于同步采集系统的频率发生器模块的概念。频率发生器采用数控振荡器(NCO)和PI控制器进行建模，输出相位误差为每秒一个脉冲(1-pps)。同步使用GNSS的1-pps作为同步系统的参考。

Global sample synchronization trigger

Synchronization measurement is very useful for power systems on phase measurement, fault location detection and others. This paper describes the concept of a frequency generator module to be used on synchronized acquisition systems. The frequency generator is modeled using a Numeric Controlled Oscillator (NCO) and a PI controller feeding back with phase error of one pulse per second (1-pps) output. The synchronization uses 1-pps from a GNSS as a reference for the synchronization system.
