Abstract


In present days, the use of wind energy is growing rapidly to generate and supply electricity as grid connected or standalone mode. To generate electric power from such non-conventional sources, self-excited induction generator (SEIG) is found to be a suitable option for either using in grid connected mode or isolated mode. But the problems associated with SEIG are its poor voltage and frequency regulation under load and prime mover speed perturbations which put a limit on the use of SEIG for a long time. By controlling active and reactive power accurately, it is possible to regulate frequency and voltage of SEIG terminal during load and speed perturbations. In this paper, wind turbine driven SEIG system is simulated by taking different types of loads such as resistive load, R-L load, induction motor (IM) load to investigate the fault identification methodologies of SEIG system. Also, presents the step-by-step development of models for different units of the SEIG with the steady-state and transient analysis for performance prediction and design of excitation capacitor. The wind turbine driven SEIG system of 4.2 kW  and a 3.7 kW induction machine are taken and simulated in MATLAB/Simulink environment.
