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