摘要
介绍了嵌入式PC技术在电力故障波形重现装置中的应用。该装置采用嵌入式PC实现人机交互,并通过串口发送命令至后台数字信号处理模块,使其发出脉宽调制波控制功率放大输出。另外,装置还应用了闭环校正技术,用反馈采样数据修正原始数据,使非线性失真达到最小,保证了重现的电力故障波形失真小的效果。
The application of embedded PC technology in power fault recurrence device is introduced. The embedded PC is used to realize man-machine interaction and send demands to digital signal processor module through serial ports,for producing pulse width modulation waves to control power amplification output. The closed - loop technology is applied to modify the original data with the feedback sampling data,minimizing the non-linear distortion and ensuring little distortion of power fault recurrence waves.
