摘要：

Recently, the negative effect of leakage current in the dc side of photovoltaic (PV) generation systems has been widely reported. Due to the large area of PV arrays, it becomes a secondary noise source that generates radiation emission. This paper presents a detailed analysis of near-field radiation of PV panels. A novel antenna model is proposed to study this phenomenon. In contrast with other literature, the novelty of this paper reveals that radiation emission should be divided into two categories: megahertz-level low-frequency emission and gigahertz-level high-frequency emission. It is derived from the proposed planar antenna equivalent model and microstrip antenna equivalent model, respectively. It is proven that near-field distribution of the PV panel is frequency related and that high-frequency near-field emission can differ dramatically from the low-frequency condition. These proposed concepts have been verified experimentally with in-circuit tests in a 100-kVA PV generation system.
