Harmonic elimination in induction generator based Micro-Hydroelectric schemes

Abstract

Micro‐hydroelectric systems are used in remote rural areas extensively due to the low cost with lot of unsatisfactory system performance. This paper presents results obtained from experiments undertaken on a standalone micro hydroelectric system in Sri Lanka with solutions to improve the reliability. The proposed solutions include a hybrid filtering technique to eliminate the harmonics and a new microcontroller based Induction Generator Controller (IGC) circuit.
