摘要
讨论了电网谐波检测算法的原理;研究了用于减小同步采样误差的线性内插软同步采样法,并以MCS-51单片机为核心设计实现了该谐波检测算法;实验数据表明,软采样可有效提高谐波检测精度。
The principle of the harmonic detection algorithm is discussed. The soft sampling method based on linear interpolation is studied, which can reduce the synchronous sampling error. The algorithm is realized on MCS-51. Experimental results show that soft sampling method can improve the harmonics detection accuracy.
