Analysis and design of electronic load controller using FLC for self excited induction generator

This paper describes the mathematic modeling of self excited induction generator (SEIG) with electronic load controller (ELC) for micro hydel application supplying variety of loads. Electronic load controller is a combination of current controlled voltage source inverter (CC-VSI) and a high frequency dc chopper which keeps the generated voltage and frequency constant in spite of change of balanced loads. Fuzzy logic controller (FLC) is implemented instead of PI controller in control circuit of ELC. Simulation results using MATLAB/SIMULINK software shows that generated frequency and voltage remain constant with change in load. The proposed electronic load controller act as, harmonic eliminator, load balancer and load controller
