Simulated performance evaluation of SEIG with electronic load controller used in renewable energy conversion system

Computational software technology in modeling and simulation has revolutionized the methodology of research in engineering. This paper presents the use of MATLAB software tools for modeling and simulation in the field of power electronics and its applications in renewable energy conversion systems. In this paper the simulation using MATLAB/Simulink environment has been carried out to evaluate the performance of 3-phase self-excited induction generator (SEIG) with electronic load controller used in micro/pico hydro power generation system. The main aim of the control strategies for 3-phase self-excited induction generators is to regulate or maintain the desired voltage and frequency of the generated output. This is achieved using electronic load controller. The main function of the electronic load controller is to maintain the output load constant as seen by the induction generator under different consumer load conditions and also to maintain the required power quality standards. In this paper, simulated results of performance of 3-phase SEIG with electronic load controller feeding isolated load under different operating conditions has been presented. The simulation software with strong graphical programming tools gives the liberty to continuous upgrade the system until optimized results are achieved which can be used in real time hardware implementation of the designed system.
