    ;
    This paper presents the investigation of skew effects on the performance of three phase, 2.2 kW 220/380 volt 4 poles self - excited induction generators (SEIG) with skewed squirrel cage rotor. Analysis of excitation capacitor of the SEIG based on a steady - state equivalent circuit model including rotor skew effect is given. Skewed rotor with angle of 0°, 5°, and 10° for the SEIG are employed. Testing and performance comparison under dynamic and steady - state operation with resistive and resistive - inductive loads have been performed. Results can be guidelines for development of effective wind induction generators. © 2007 IEEE.

    A simple approach to capacitance determination of self - exited induction generators for terminal voltage regulation

    This paper proposes a simple method for determining of capacitance requirements of three phase self-exited induction generators(SEIG). Consideration of capacitance of the SEIG based on equivalent circuit model under steady - state load conditions and a power flow diagram is given. Performance testing has been performed under a wide range of operating conditions such as no - load and on - load with pure resistive and resistive - inductive load conditions. Experimental results can be guidelines for simply suitable capacitance determination method for SEIGs with reasonable terminal voltage regulation under a wide range of operation. © 2007 IEEE.
