PMU检定装置的研制

The research of PMU calibration device

采用数字频率合成技术,以GPS—1PPS为同步信号,合成频率相位基准信号;采用基于DSP的直接数字频率(DDS)合成技术,合成与GPS秒脉冲同步的标准信号源,将功率放大、输出回路、采样、数字PID和嵌入式计算机一起组成了PUM的检定装置。

Adopt digital frequency synthesizing technology, utilize GPS-1PPS as synchronized signal to synthesize frequency phase datum signal; apply DSP-based direct digital signal （DDS） synthesizing technology, synthesize a standard signal source that carries synchronized pulse measured in second with GPS. The PUM calibration device is a combination of power magnification, output loop, sampling, digital PID and computer-on-module.
