Abstract

In this article

it is introduced that a case of three-harmonic stator grounding protection action in a power plant. The logic principle of three-harmonic stator grounding prection is introduced

the generator failure phenomenon is described

and the three-harmonic stator grounding protection logic principles are given. Through the analysis of the fault data

the failure place is determined and eliminated.
