摘要
为了抑制配电网谐波谐振引发的过电压,需要准确获得谐振的各种信息,如谐振频率、最高激发点、最高观测点以及参与因子。为了提高计算效率,文中提出一种基于自适应扫频技术的配电网谐波谐振模态分析法。该方法利用自适应扫频技术确定谐振频率,应用模态分析法确定谐振信息。仿真结果表明,文中提出的方法能够高效准确地确定出配电网谐波谐振频率及最高激发节点。
In order to suppress the overvoltage caused by harmonic resonance in distribution network,it is necessary to obtain accurate information of the resonance,such as resonance frequency,maximum excitation point,maximum observation point and participation factor.To improve the efficiency,a harmonic resonance modal analysis method of distribution network based on adaptive sweep technique is proposed.The proposed method uses adaptive sweep technique to analyze the resonance frequency resonant frequency,and then utilizes modal analysis to obtain the resonance information.Simulation results show that the proposed method can efficiently and accurately recognize harmonic resonance frequency and the maximum excitation node of the distribution network.
