Transient Analysis Of Self Excited Induction Generator With Electronic Load Controller (ELC)

Abstract

Fast depletion of fossil fuels has drawn attention towards the use of nonconventional energy sources like wind, biomass, tidal/wave, and small hydro potential. In remote locations, harnessing of electrical energy from such local resources can be cheaper and easier compared to grid connection, which involves long transmission lines and associated losses. A micro-hydro system using natural hydro potential with minimal civil works is a strong candidate in this race. Uncontrolled low head turbines are prescribed for such applications. In this paper, a transient investigation of a self-excited induction generator (SEIG) with electronic load controller (ELC) utilized as a part of stand-alone smaller scale hydro power generation utilizing uncontrolled turbines. In perspective of the need to sustained single phase loads from such frameworks, the transient behavior because of switching in of such loads is of interest and is completed here. A composite scientific model of the total framework has been created by consolidating the demonstrating of prime mover, SEIG, ELC, and load. Simulated results are contrasted and the exploratory ones, acquired on a created model of a SEIG-ELC framework for the beginning of an IM and switching in a resistive load. For the beginning of an IM, a star/delta starter is utilized to stay away from inrush current. Keywords: Dump load, ELC, induction generator, PI controller
