Abstract

This paper presents an optimization based scheme to derive the maximum 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 considering 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 objective function. Fmincon optimization toolbox of MATLAB has been used to solve this numerical based problem. The critical power and the maximum power transmission capability have been investigated for variations of capacitor, load power factor and speed. The power transmission 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.
