摘要

谐波阻抗的测量与微电网的稳定性密切相关，因此在微电网中具有重要的应用价值。本文提出了一种新的电流注入阻抗测量方法。正弦调幅是一种将信号移到不同频带的方法。用正弦波调幅叠加方形脉冲信号，可以得到带宽大、幅度衰减小的信号。当叠加信号作为电流源注入系统时，可以计算出感兴趣频率范围内的阻抗信息，时间成本短，精度高。仿真结果验证了该方法的有效性。

A new current injection method for impedance measurement using superposed modulated square pulse

Harmonic impedance measurement is very important in Micro-grid because of the close relationship between impedance and stability. This paper presents a new current injection method for impedance measurement. Sinusoidal amplitude modulation is a method to shift signals to different frequency bands. A signal with large frequency bandwidth and small amplitude attenuation can be obtained by superposing square pulse signals with sinusoidal amplitude modulation. When the superposed signal is injected to the system as a current source, impedance information in the frequency range of interest can be calculated with short time cost and high accuracy. The simulation results demonstrate the effectiveness of this method.
