PV system has been rapidly developed in recent years, while it generates harmonics and there-phase unbalance for its grid-connected inverter, causing voltage fluctuations flicker uncertain power output. Therefore, quality is highlighted as an important parameter of the system. To study actual characteristics system, a large-scale BIPV plant was investigated. This paper discussed parameters defined by standards introduced key structure Based on field tests taken under different conditions summer winter, explored operating harmonics, current three-phase unbalance, flicker, active reactive properties, etc. Results demonstrate provide reference evaluation similar systems.
