Experimental Investigations on Loading Capacity and Reactive Power Compensation of Star Configured Three Phase Self Excited Induction Generator for Distribution Power Generation

Self excited induction generator (SEIG) is gaining popularity for off-gridpower generation due to the inherent advantages. This paper presents a pri-mary experimental investigative study on the performance of three-phase starconfigured SEIG (Y-SEIG). The aim of the experimental work is to identifya 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 ofSEIG for calculation of minimum excitation capacitance are also highlightedin this paper.
