EFFECTS OF MACHINE PARAMETERS ON PERFORMANCE OF SELF-EXCITED INDUCTION GENERATOR UNDER UNBALANCED OPERATION

Yatender Chaturvedi , Kanwarjit Singh Sandhu

The unbalanced loading on SEIG is the common phenomenon which generally occurs due to singlephase load(domestic load) and may deteriorate the performance of such machines. This paper presents a new model which has been used to analyze the effects of machine leakage reactance on performance analysis of SEIGs under the unbalanced operations. From simulation results it is found that degree of unbalance is strongly affected by the machine parameters as compared to its resistances. The simulation study as performed on 15kw machine may be useful to design the machine for such operations.
