This study was conducted through the analysis of the frequency in the steady state and transient case using a developed induction generator numerical model. The simulation results obtained by numerical model are validated using an experimental test bench. For frequency control a fuzzy logic controller is presented in the paper and validated using Matlab-Simulink environment. The simulation results obtained by fuzzy controller are compared with those provided by a specific law obtained from analytical study of induction generator.

This paper presents the improvement procedure of the transient state and the regulation of the output frequency by adjusting the terminal capacitor. The aim is to provide frequency control of a self-excited induction generator in remote site using different strategies which are based on the adjustment of the reactive power at the outputs of a three-phase self-excited induction generator. A thyristor controlled reactor and a switched resistive load will be used to control reactive power. The proposed particle swarm optimization algorithm technique, location of the thyristor controlled reactor device, and parameter value are optimized simultaneously. The results obtained by this strategy will be compared with those provided by the use of Fuzzy Logic Controller. This study will be conduc...

The behavior of an induction generator working in autonomous mode and which supply an inductive resistive load is presented using a numerical model developed in Matlab-simulink. The startup phenomenon and the problematic which appear for this working mode are presented and discussed leaning on the simulated results obtained from various studied cases. Computed characteristics have been verified experimentally in laboratory using three-phase squirrel-cage induction machine. Significant agreement between experimentally and simulated results obtained with proposed numerical model is shown in the paper.
