Abstract:
In remote locations/rural areas where transmission cost is very high a self excited induction generator driven by micro-hydro turbine can be installed easily and economically.
To excite the generator, external reactive supply can be supplied from the grid or from the externally connected capacitor bank.
In this thesis, a two identical induction generators excited with symmetrical capacitor bank are use. The generators are driven by micro-hydro turbine. These induction generators supply a pure resistive load in isolated area.
PID controller is used to reduce the oscillation during the transient fault and also to improve the steady state response. The complete model is developed and simulated using MATLAB/Simulink software.
The simulation is carried out for steady-state and transient operation. The results are obtained and discussed.
