A Single Phase Induction Generator As Wind Generator – A New Concept and Design

Abstract- Experimentation is done on a standard induction motor, run as a single phase induction generator. The guidelines obtained from the performance of this trial machine are used to design and construct a novel prototype single phase induction generator. This novel design combines the concepts of ac tachogenerator, ac servomotor and dc self excited generator. It can generate at low sub synchronous speeds corresponding wind speeds being of the order of two to three meters/sec. Utility of this machine for converting wind power to electrical power for household consumption is put forth as a novel concept in this field. Details of construction and mathematical design of a prototype machine are given. The performance of the prototype machine is shown to tally well with the design. Key words –wind generator Tachogenerator, sub synchronous speed, push pull amplifier, prototype machine etc I
