Keywords: Self excited induction generator (SEIG), minimum excitation capacitance, reactive power (VAR) compensation, distributed power generation, voltage regulation


Self excited induction generator (SEIG) is gaining popularity for off-grid power generation due to the inherent advantages. This paper presents a primary experimental investigative study on the performance of three-phase star configured SEIG (Y-SEIG). The aim of the experimental work is to identify a simple and cost-effective scheme of self-excitation and reactive power (VAR) compensation among the six possible operational configurations. From the investigated results, it is found that the capacitor excitation and VAR compensation in the delta connection scheme give the better performance. Experimental test procedure and obtained values of steady state analysis of SEIG for calculation of minimum excitation capacitance are also highlighted in this paper.
