Abstract
This paper presents steady-state characteristics analysis of a self-excited single-phase induction generator (SPIG) which supplies an isolated load. The self-regulated characteristics of a SPIG by connecting external capacitors are examined. The system consisting of both shunt and series capacitors in short shunt and long shunt connections to improve voltage regulation of SPIG has been analyzed. Based on two-phase symmetrical components equivalent circuit model, a fast iterative approach to simulate the operated state of a SPIG is developed. To demonstrate the effectiveness of the proposed approach, the approach has been tested on a practical motor-driven SPIG. Very close agreement between experimental and simulated results has been obtained.
