Research on Harmonic Source Analysis and Harmonic Transfer in Power System

This paper systematically analyzes the characteristics of harmonic current source, harmonic voltage source and background harmonic voltage source, and studies the transmission law of harmonic distribution network. A specific case of a cold rolling mill is analyzed, and the transmission law of harmonics in the distribution network is verified by using the test data. The influence of different harmonic sources on filter devices installed in the distribution network is discussed. The work done in this paper has a guiding role in the analysis of harmonic power flow in distribution network, the design of harmonic filters and the checking of parameters.
