Distributed Induction Generators: 3 - Phase Bolted Short - Circuit Fault Currents

This paper presents methods for estimation of the value of the 3-phase bolted short circuit current of induction distributed generators. It justifies new, quick, and fairly simple way for approximation of the value of peak currents during the first several cycles of the fault. During the study, numerical simulations of the fault have been performed and compared to the results from the estimation. The analytical and numerical results have been validated by a scaled-down experimental setup with a 2 kW induction generator.
