“…This allows an influence from the proximity effect. Hence, the effective rotor resistance R r_eff and inductance L lr_eff as in (35) are obtained as a function of the proximity effect and used in the conventional machine model.…”

“…Various techniques for improving voltage regulation such as a switched capacitor scheme, electronic load controllers, variable VAR controllers and other solid state controllers have been reported in the literature [28][29][30][31][32][33][34][35]. These techniques improve the performance of a SEIG significantly, but involve complex and expensive control hardware, hence militating against SEIG's features of simplicity and reliability [2].…”

“…To achieve a given voltage level in an SEIG, an external capacitor bank must be able to supply the magnetising current of that level. Necessary background literature on the steady-state performance analysis, selection of excitation capacitors and transient performance analysis of SEIG has been obtained from 13 different sources [23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Self-excited induction generators (SEIGs) will play an important role in off-grid wind power generation. To advance understanding of the significance and prospects of SEIGs, this paper elucidates the significance of incorporating the proximity effect in the conventional model of self-excited induction generators. The researchers offer an analytical model to incorporate the proximity effect in the rectangular rotor bars of the SEIG. The model's accuracy relies on a computer program. The calculated results are experimentally verified in the case of two 7.5 hp aluminium-and copper-rotor SEIGs under open-circuit and static loading conditions, through an exclusive qualitative analysis of terminal voltage build-up at no-load, variation in terminal voltage and frequency, as a function of the proximity effect. The paper examines also the voltage regulation, frequency regulation and excitation capacitance requirements of both aluminium-and copper-rotor SEIGs.
