基于ARM的电压移相实验教学平台设计

摘要

The paper introduced the functions of digital voltage phase-shifting and amplitude adjustment based on microcomputer ARM. It can realize phase-shifting of voltage wave signal between 0~360 degree by using the method of RAM round alignment,and it can hold the line of frequency in the process of phase-shifting. The voltage amplitude of phase-shifter output can be adjusted,and output certain power. The equipment can be used in experiment teaching of relay protection and microcomputer relay protection as Experimental Teaching Platform in university.%　　本文介绍了基于ARM微处理器实现数字式电压移相与幅值调节功能，采用RAM环形队列实现电压信号波形在0～360度范围内移相，且在移相过程中保持电压波形频率不改变；并可以对移相器输出的电压幅值进行调节，输出一定的功率。该设备可以在高校继电保护及微机型继电保护实验教学中作为实验教学平台应用。
