Abstract
Islanding phenomenon of utility-connected photovoltaic power conditioning systems(PV PCS) can cause a variety of problems and must be prevented. If the real and reactive power supplied by PV PCS are closely matched to those of load, islanding detection by passive methods becomes difficult. The active frequency drift(AFD) method, called the frequency bias method, enables islanding detection by forcing the frequency of the voltage in the islanding to drift up or down. In this paper, non-detection zone(NDZ) of AFD is analyzed for the islanding detection method of utility-connected PV PCS by the simulation software tool PSIM.Keywards : 단독운전(islanding), 계통연계(utility-connected), 태양광 시스템(PV systems), 능동주파수천이(active frequency drift), 불검출영역(non-detection zone), 인버터(inverters)기 호 설 명
