A fuzzy logic and numerical frequency control of a self excited asynchronous generator in remote site

This paper presents a comparative study for two frequency control strategy applied to a self excited induction generator equipping a wind turbine in remote site. 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.
