Experimental Study on Six-phase Synchronous Alternator for Stand-alone Renewable Energy Generation

Abstract—A purely experimental analysis is presented in this paper to study the performance characteristics of a six-phase synchronous alternator coupled to a hydro turbine for stand-alone energy generation. It is depicted that the alternator is well suited to supply two independent three phase loads. Performance of the machine was observed with resistive load (i) on single winding set and (ii) on both the winding sets for constant field excitation, for constant frequency, and for constant voltage operation. Experimental results were recorded considering independent loading of two three phase stator winding sets with equal and unequal balanced resistive loads. A Fluke 43 Power Quality Analyzer was used for the measurement and recording of different waveforms.
