This paper presents an optimization based scheme to derive the maxi-
mum power transmission capability of a self-excited six-phase induction
generator (SPIG). For execution of this proposed scheme, an easy and
straight forward method has been developed here for figuring out the
maximum amount of power which can be transmitted by SPIG consid-
ering different functional conditions. An optimization based problem is
formulated with the help of multi-variable constraint, for finding out the
maximum power transmission capability of SPIG. The total impedance of
SPIG, calculated from its equivalent circuit, is considered as the objec-
tive function. Fmincon optimization toolbox of MATLAB has been used
to solve this numerical based problem. The critical power and the max-
imum power transmission capability have been investigated for varia-
tions of capacitor, load power factor and speed. The power transmis-
sion capability of SPIG directly depends on the factors like machine
parameters, rotor speed, power factor of the load and the capacitance value of self-excitation. From the analysis of the simulated results, it is
found that the performance of SPIG is satisfactory for various operating
conditions.
