Steady-state analysis of Self -Excited Induction Generator

This paper deals with an approach for the steady state analysis of Self Excited Induction Generator (SEIG). When an induction generator is used in an isolate operation, it operates in self-excitation mode. Therefore the advanced knowledge of the maximum excitation capacitor value is required. To find this capacitor value two non-linear equations have to be solved. Different numerical methods for solving these equations are known from previous literature. In this paper, the steady state characteristics of a self-exited induction generators is analysed using MATLAB. Simulation analysis is performed to investigate of SEIG characteristics, including real and imaginary-impedance characteristics. Based on the analysis, the SEIG operating characteristics are studied.
