| Research Abstract |
A large quantity of photovoltaic(PV) systems will be installed in near future. There would be a serious power system disturbance if they would be stopped by voltage sags. This study solved the difficulty in generating voltage sags with controlled parameters or reproducing actual voltage sags precisely in laboratory, using PC for waveform composition and linear power amplifier representing voltage source modeling actual power system. The Precise studies on behaviors of magnetic contactor behavior and for power system connecting inverters for voltage sags have been carried out.
