Investigations on single-phase self-excited induction generator for standby power generation

The paper presents different modes of operation of single phase self-excited induction generator, using a commercially available single phase induction motor. For single phase self-excited induction generator system in corporating a combination of shunt and series capacitor has been suggested. In this paper the result of a detailed experimental investigation are presented to assess its suitability for practical applications. The effect of shunt capacitor, series capacitor and load are investigated. It is observed that the performance of single winding machine is poor with unsatisfactory voltage regulation but the performance considerably improves with the inclusion of series capacitor. This investigation, therefore provides a workable analytical model for single-phase self-excited induction generator using two winding configuration has immense standby power generation using single phase self-excited induction generators.
