An experimental investigation of self-excitation in stand-alone induction generator

This paper presents dynamic modeling of self-excited induction generator (SEIG) using state space approach. The proposed dynamic model consists of induction generator, self-excitation capacitance and load model are expressed in stationary d-q reference frame with the actual saturation curve of the machine. The dynamic performance of SEIG is investigated under no load, with load and perturbation of load. To predict the performance of the purposed system, a MATLAB/ SIMULINK based simulation study is carried out. Viability of the excitation process is ascertained through experimental results obtained from the laboratory prototype.
