Experimental Analysis on Influences of Harmonic Voltage at High-Voltage Network on Harmonic Current at Medium-Voltage Network [PDF]

open access: yesJournal of International Council on Electrical Engineering, 2012
In this paper, we describe how harmonic voltage in transmission networks influences harmonic currents in distribution networks. In the conventional equivalent circuit for harmonic analysis based on computer simulations, harmonic currents in distribution networks were regarded as a constant harmonic current source.

Study on harmonic source model of millisecond pulsed power load based on switching functions

open access: yesEnergy Reports, 2020
Modern radar is a typical millisecond pulse power load (MPPL), which contains a large number of power electronic devices. If the MPPL is connected to the power system, it will cause serious voltage distortion problems. The working mode of the radar pulse
