交流采样测量技术及其应用

Digital Sampling Techniques and Its Application in Electric Power Measurement

交流采样测量技术是七十年代发展起来的一种新的测量技术,目前已广泛应用于交流电参数精密测量的许多场合。本文就国内外出现的三种主要算法的优缺点作一比较,并对由信号谐波引入的算法误差作了仿真计算,最后得出了新的结论。

This paper has reviewed several published algorithms of electric power measure- ment based on digital Sampling,including Synchronous Sampling Algorithm,Compensation Algo- rithm and a new algorithms using digital filters,Main features of these algorithums are presented and comparied,and the applications of them are proposed.The simulation result shows that the algorithm based on digital filters has a better computing precision under the condition of the same sampling rate.
