An approach employed for the evaluation of performance of self excited induction generator (SEIG) using fuzzy logic which needs a simple modelling is proposed in this paper. In general, the conventional techniques with analytical equations are used to analyse the performance of SEIG. Here a fully fuzzy based approach is tried to evaluate the performance. The results obtained from fuzzy logic approach...
A method has been developed for the analysis of operation of self-excited induction generators (SEIGs) supplying battery charging loads through three-phase semi-converters by representing the battery circuit as equivalent resistance and reactance in the equivalent circuit of these generators. Such equivalent values are functions of the dc charging voltage and current and the control angle set in the...
A single-phase semi-converter fed battery charging circuit meant for being supplied from a wind-driven self-excited induction generator is analysed with Symmetrical Angle Control (SAC) scheme. Several modes of operation of this scheme with continuous as well as discontinuous load current have been identified as revealed by the input and output voltage and current wave forms depicted for each one of...
A simple method involving only a quadratic equation has been developed for calculating the minimum and maximum values of excitation capacitance that will sustain self-excitation in an induction generator meant for isolated power supplies. This approach has also been further extended for the determination of maximum load of a given power factor that could be applied to the generator without losing...
A system of 1-phase semi-converter fed battery charging circuit meant for being supplied from a self-excited induction generator is analysed with extinction angle control (EAC) scheme. Several modes of operation of this scheme with continuous as well as discontinuous load current have been identified and the input and output voltage and current wave forms for each one of them have been depicted.
