Step by step approach for developing analytical and experimental research facilities of a three-phase self-excited induction generator

Abstract

Self-excited induction generators (SEIGs) have been rigorously investigated in last few decades owing to their suitability for standalone renewable energy applications. Various issues pertaining to their modeling and control are quite aptly addressed in several analytical and experimental studies. However, these analyses are often focused on elaboration of proposed innovations and findings while the important details on modeling and implementation of SEIGs are left to be explored by readers. In this paper, a step by step approach for the mathematical modeling of three-phase self-voltage regulating, short shunt SEIG in stationary reference frame is explained. Subsequently, the developed d-q model of SEIG is implemented in terms of a simulation model. The developed model is then employed to carry out performance analysis of 3-phase, 2.2 kW SEIG supplying R-L load. All the results are verified with good accuracy in a SEIG test-rig whose details are included in the paper. The prime objective of this work is to provide a consolidated source for developing research resources of a self-voltage regulating three phase SEIG.
