A State of Art and Comprehensive Study of Renewable Energy Systems Based on Three-Phase Self Excited Induction Generator Feeding SinglePhase Loads

This paper presents a comprehensive study of three phase SEIG (Self-Excited Induction Generator) feeding power to single phase loads exploiting renewable energy sources (RESs) and such systems are of great importance for the developing countries with remote location without grid connectivity. This paper includes the various excitation circuit topologies, voltage and frequency control schemes, steady-state and transient analysis techniques for three-phase SEIG connected to single-phase loads. The paper also presents the steady-state mathematical model of three-phase SEIG with single-phase loads, which is very useful for deciding the size of excitation capacitor in the different configurations.
