Abstract

Determining the harmonic responsibilities of utility and customer side at a PCC has been a great concern in harmonic research, and utility harmonic impedance is a key factor for assessing harmonic emission levels. When background harmonic is unstable, traditional methods have a large error. A new method is proposed in this paper to assess harmonic impedance based on minimum energy fluctuation. The method can calculate harmonic impedance by constructing an object function which minimizes the background harmonic energy fluctuation, without assuming background harmonic is stable. Simulation analysis indicates that the proposed method is more reliable to calculate harmonic impedance, which can reduce the error caused by the fluctuation of background harmonic.
一种谐波阻抗估计的新方法
确定PCC中公用事业方和用户方的谐波责任一直是谐波研究的热点,而公用事业谐波阻抗是评估谐波发射水平的关键因素。当背景谐波不稳定时,传统方法误差较大。本文提出了一种基于最小能量波动的谐波阻抗评估方法。该方法在不假设背景谐波稳定的情况下,通过构造使背景谐波能量波动最小的目标函数来计算谐波阻抗。仿真分析表明,该方法计算谐波阻抗更可靠,减小了背景谐波波动带来的误差。
