Abstract

The effect of various installation positions of a frame wire installed in a photovoltaic (PV) power generation system on radiation noise from the DC side of such a system is investigated in the frequency range from 150 kHz to 30 MHz. First, a PV measurement model with two PV panels is proposed. The radiation noise from this model is compared with that from a simulation model. Good agreement between the measured and simulation results is obtained. Then, the radiation noise from this model with various installation positions of the frame wire is investigated. When the frame wire is installed along power lines, the radiation noise is suppressed at low frequencies where the phases of the currents of the power lines and the frame wire are reverse. Furthermore, the radiation noise increases at low frequencies when the frame wire is vertically installed between the corner of the PV panels and the ground plane. This increase is caused by the loop formed by the PV panels, power lines and the frame wire.
