摘要
扩展Prony算法在无噪声和高信噪比情况下能精确检测到电网中非整数次谐波,本文针对扩展Prony算法抗噪的弱点提出运用一种迭代Prony算法对电力系统整数和非整数次谐波进行检测,在信噪比20dB有很高的精度。数值仿真验证了本算法的有效性。
Extending Prony method can detect integer harmonics and non-integer harmonics without noises. In order to apply its advantage and overcome its shortcoming, in this paper an iterative Prony method is introduced to detect integer harmonics and non-integer harmonics, which get to high precision in SNR 20 dB. The result of simulation has proved the validity and accuracy of this method.
