The safety of line crew personnel and others is a major concern of electric power utilities regarding the widespread use of grid-connected photo-volataic (PV) power sources. PV sources feed power back to a utility grid through Static Power Converters (SPC's), which are designed to shut down when disconnected from the grid. SPC's have been shown to continue to operate or run-on under certain conditions. A model for a commercially available self-commutated SPC is developed to investigate the conditions under which isolated operation (islanding) occurs. The approach used in modeling the SPC is unique in islanding studies. It is based on solving complex-ac system equations and Phase-Locked Loop differential equations simultaneously to determine the SPC response. The model accurately and optimistically predicts the islanding performance of the self-commutated SPC, as verified in laboratory experiments and detailed computer simulations.
