The Application of Induction Generators for Remote Micro-Hydro Systems in Developing Countries

Abstract The application of induction generators for remote area power supplies is discussed with particular reference to developing countries. A method of calculating the minimum value of self-excitation capacitance necessary to initiate self-excitation with a stand-alone induction generator is described. Final steady-state self-excitation voltages and frequencies are also evaluated for both loaded and unloaded operation and they are shown to vary with the load demand, in some cases causing poor quality of supply. A new technique is proposed for voltage control to improve the regulation with load.
