摘要

本文研究了典型工业配电系统中的谐振及其对谐波畸变的影响。描述了研究中使用的系统,并详细介绍了所考虑的案例。利用PSCAD和Matlab计算机程序进行频率扫描分析。结果显示了系统在不同频率下的阻抗,代表了谐波源所看到的阻抗。该研究成功地揭示了不同情况下组合系统阻抗的共振频率和相关幅度。共振在这些频率的发生解释了为什么谐波失真随情况而变化。

Simulation of resonance and harmonic amplification in industrial distribution system
This paper presents a study of resonance and its impact on harmonic distortion in a typical industrial distribution system. The system utilised in the study is described and cases considered are detailed. The study is performed using frequency scan analysis with the aid of PSCAD and Matlab computer programs. The results, which visualize the impedance of the system at various frequencies, represent the impedance seen by harmonic source. The study has successfully revealed the resonance frequencies and associated magnitude of different cases of combined system impedance. The occurrence of resonance at these frequencies explains why harmonic distortion varies with the cases.
