摘要
本文利用TMS320C5402的高速计算功能,设计了一种新的交流采样系统,该系统利用小波变换的优越特性对采集到的电压和电流信号进行处理,克服了原来在计算无功功率过程中由于对电压求导所引起的误差增大现象,实验结果表明,这种检测方法具有较高的精度。
This thesis introduces a design method of alternating sampling system, which is greatly applicated in power system. This system utilizing the superiority of wavelet transform processes the discrete voltage and current, it overcome the error increase for derivate voltage during the course of calculation inactive power, the result of experiment indicates that this method has high precision.
