For low power wind energy or micro-hydel applications of the order of 1-10KW, the lowest cost can be achieved if the generator is a simple squirrel cage induction motor used as a self excited induction generator (SEIG). The induction generator output can be rectified to produce a DC Bus from which a single phase inverter can feed the power supply grid. A SEIG requires capacitors to be connected...

In contrast to conventional generators, self-excited induction generators are found to be most suitable machines for wind energy conversion in remote and windy areas due to many advantages over grid connected machines.

This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self excited induction generators (SEIGs) supplying balanced/unbalanced and linear/non linear loads. A threephase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) known as STATCOM is used for harmonic elimination. It also provides the requi...

In this new millennium, the induction generator, with its lower maintenance demands and simplified controls, appears to be a good solution as isolated power supply schemes for rural electrification. Recent emphasis on the utilization of clean and renewable energy sources to reduce dependency on fossil fuels makes the use of SEIG even more attractive because vast amount of energy sources, such a...

In the present paper Matlab toolboxes are employed to estimate the steady state performance of self excited induction generator [SEIG]. Efforts are made to predict the performance of such generator with different values of excitation capacitance under any operating condition. Simulated results as obtained using direct search toolbox, genetic algorithm toolbox and optimization toolbox are compar...

Abstract. This paper presents the steady state analysis of a wind driven single phase single winding self excited induction generator (SEIG) with and without shunt compensation.
