PWM Based AC-DC-AC Converter for an Isolated Hydro Power Generation with Variable Turbine Input

Abstract

This paper presents performance analysis of a PWM based AC-DC-AC converter implemented for a three phase self-excited induction generator (SEIG)based micro hydro power generation. In this work, the feasibility study of generating and supplying reliable power from freely flowing water to a remote area is presented. The power generation with variable water flow to the turbine is found to be feasible with satisfactory power qualities at different loading conditions of the generator. Investigations on power quality issues are carried out for both linear and non-linear types of loads. The proposed system is modeled in MATLAB/Simulink environment. The simulation results are presented.
