Harmonic Contributions Evaluation With the Harmonic Current Vector Method
TLDR
In this article, a method to evaluate harmonic contributions at the point of common coupling is presented, which is based on the harmonic current vector method where reference impedances are introduced, and long-term measurements are proposed for determination of harmonic contributions.Abstract:
A method to evaluate harmonic contributions at the point of common coupling is presented in this paper. The proposed approach is based on the harmonic current vector method where reference impedances are introduced. Resistance defined at fundamental frequency with measurements is used as the customer-side reference impedance. The presented method allows calculation of harmonic contributions without knowing the actual customer impedances. It also enables better evaluation of the customer and utility harmonic contributions in resonance conditions. The method is verified through a simulation study and with extensive field measurements. Long-term measurements are proposed for determination of harmonic contributions.read more
