Purpose – The purpose of this paper is to present analysis of an influence of rotor slots opening on self-excitation process, terminal voltage and performance characteristics of the single-phase self-excited induction generator (SPSEIG). Design/methodology/approach – The paper presents field analysis of the self-excitation problem in the SPSEIG and performance characteristics on the base of two-dimensional field-circuit model of the generator. Findings – The carried out field computations of the tested SPSEIG with closed rotor slots showed that only an initial voltage across the excitation capacitor of about nominal value (230 V) causes successful self-excitation of the generator. It was also proved that the suitable opening of the rotor slots, beside remnant flux density in the rotor core, facilitates self-excitation in the generator. Since in working applications initially charging of the capacitor to almost nominal voltage may cause a problem, therefore employment of semi-closed rotor slots in the SPSEIG would be proper solution. Originality/value – The conducted simulations, validated by laboratory tests showed that not only suitable excitation capacitor capacitance and rotor speed are needed to obtain desired terminal voltage of the generator, but also suitable initial voltage across the capacitor in auxiliary stator winding is very important and necessary for reliable self-excitation of the single-phase induction generator with closed rotor slots. The employment of semi-closed rotor slots in the SPSEIG makes the self-excitation more effective.

Characteristics Analysis

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.
