Abstract :
Recently, the negative effect of leakage current in the DC side of photovoltaic (PV) generation system has been widely reported. Due to the large area of PV array, it becomes a secondary noise source that generates radiation emission. This paper presents a detailed analysis of near field radiation of photovoltaic 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: low-frequency emission and high-frequency emission. It is proven that near field distribution of PV panel is frequency related and high-frequency near-field emission can differ dramatically from low-frequency condition. These proposed concepts have been verified experimentally with in-circuit tests in a 100 kVA PV generation system.
