SELF EXCITED INDUCTION GENERATOR FOR PICO HYDRO STATION IN REMOTE AREAS

Abstract

The increasing use of renewable energy sources such as wind energy, solar energy, bio gas energy and small hydro energy have gained success in rural electrification which has potential and competence of operating in the remote and hilly areas with very low cost generating system. With wind turbine and micro/mini hydro generators as an alternative source of energy it can deliver electricity to millions of people and improve life standard and create jobs where the extension of grid require a huge investment in infrastructure because of its very cost effective and decentralize system. The induction motor is the widely used electric machine which can work reversible and operate as induction generator for autonomous operation. The self excited induction generator (SEIG) are found to be most suitable for electrification rural isolated areas using locally available renewable energy because of its advantages well known. This report focuses on the dynamic study of SEIG-self excited induction generator which is driven by a constant stable torque from hydro turbine is done with the help of MATLAB/SIMULINK software to predict and analyze the performance characteristic of SEIG under different conditions, this thesis aims to study the work done by researchers in evaluating and analyzing the characteristic performance of SEIG-self excited induction generator and its operation under different conditions which includes process of self-excitation, different kind of loading, Reactive Compensation with series capacitor technique and SEIG with electronic load controller (ELC) technique.
