Abstract

In this paper, a novel adaptive stator ground fault protection scheme based on third-harmonic differential voltages is implemented on a lab scale synchronous generator. The lab scale generator is used to emulate the fault characteristics of large industrial generators along the stator windings. Simulations based on Finite Element Analysis (FEA) method and experimental results prove the expected fault characteristics as well as fault detection capability of the adaptive stator ground fault protection scheme.
