DSP Based Induction Generator Controller for Single Phase Self Excited Induction Generator

Abstract

This paper presents the design and implementation of a digital signal processor (DSP) based induction generator controller (IGC) to regulate the voltage and frequency of a single phase self excited induction generator (SEIG), suitable for stand alone power mode employing unregulated turbine such as micro-hydro power generation. The developed prototype model of a DSP based SEIG-IGC system is cost effective, reliable, flexible and capable of network based application for remote configuration with TCP/IP stack. The transient behavior of the developed DSP based SEIG-IGC system at different operating conditions such as the application and removal of static (resistive and reactive) and dynamic (single phase induction motor) load is investigated to demonstrate the capabilities of the proposed IGC.
