Popis:	Power generation from renewable energy resources has increased substantially in recent years. Wind and hydroelectric renewable sources are being widely used for power generation. Self-excited induction generators (SEIG) are used for the electricity generation from wind resources, for their robust nature. Performance of SEIG in an islanded micro-grid has been analyzed in this paper. A method is developed to identify the conditions of both SEIG and load of the micro-grid for stable operation of the network. Critical speed, critical fault clearance time and maximum loadability of the islanded micro-grid having SEIG sources, have been determined. Critical fault clearance time and critical speed 500 ms and 1.2 p.u. are found, respectively. To develop the mathematical model for the performance analysis of SEIG, a d-q frame model and thevenin equivalent circuit has been considered in this work.
