Voltage Controlled Induction Generator by Using Arduino

Abstract

The phenomenon of self excitation in an induction generator which is of  practical interest. For the induction generator using terminal capacitor across generator terminals it can generate electrical power. The capacitance value to the terminal is not constant but it is varying with many system parameters like shaft speed, load power and its power factor. If the proper value of capacitance is selected, the generator will operate in self excited mode. Hence the main drawback of induction generator in wind energy conversion system applications is its need for leading reactive power to build up the terminal voltage and to generate electrical power. Critical values of speed, below which the machine fails to self excite irrespective of the capacitance used, are found to exist.
