Abstract: This paper presents a methodology for accurately predicting the minimum value of capacitance necessary to initiate excitation in a standalone self-excited reluctance generator (SERG). The methodology is based on modeling, analysis and simulation of various capacitances to determine the range of capacitance needed for excitation. The dynamic and steady-state performances of the self-excited reluctance generator were analyzed under different operating conditions. This analysis was done by developing a complete dynamic model of SERG including the excitation capacitors and load. The performances of the machine under conditions of constant load, and varying loads were analyzed and presented. The modeling and simulation have been carried out using MATLAB‐Simulink platform. The results obtained shows that for excitation to take place, the minimum value of capacitor needed is 61µf, below which the generator will not excite. The machine could excite and attained its rated voltage between 61µf to 110µf, above which the generator begins to generate over voltage. For the dynamic performance analysis, the results shows that with the variations in the connected loads, the output frequency of SERG remains constant, which makes it a good alternative for remote area applications.
