✦ Synopsis
A high speed, reliable protection scheme eliminating islanding operation of dispersed, utility interactive PV system was developed. This scheme uses a special frequency-phase characteristics of PV inverters, which shifts the inverter output frequency out of overfrequency/under-frequency limit levels on the case of islanding. This paper presents the principle of a new, active method for preventing islanding, along with its simulation and experimental results.
