摘要

电容开关操作可用于测量网络谐波阻抗。通过电容器开关后电压和电流的瞬态分量，可以计算出PCC(共耦合点)的谐波阻抗。为了提高测量精度，本文引入TLS-ESPRIT算法，滤除电压和电流信号中的噪声和基元分量。通过时域仿真，与基于proony算法的方法相比，验证了该方法在抗噪声干扰能力和测量精度方面的优势。

Capacitor-switching based method of network harmonic impedance measurement via TLS-ESPRIT algorithm

Capacitor-switching operation can be used to measure network harmonic impedance. Via the transient components of voltage and current after capacitor switching, the harmonic impedance of PCC (Point of Common Coupling) can be calculated. To improve measurement accuracy, the TLS-ESPRIT algorithm is introduced in this paper to filter out noise and fundamental components in voltage and current signals. Via time domain simulations, the advantages of the proposed method in the ability of noise interference resistance and measurement accuracy, are verified compared with the Prony algorithm based method.
