Choosing a correct main protection configuration schemes for stator internal short circuits in generator is the premise of safe and reliable operation of the large generator. This paper firstly analyzes the general large hydro-generator stator internal short circuit fault type and fault number. It mainly does some statistics works on SF600-42/1380 generator fault location and fault number. And then through the finite element method, calculate each phase and each branch current if the generator internal short circuit happens. In the paper, we calculate the sensitivity of various kinds of main protection scheme. Get the dead zone position which easily lets the main protection device take action. Finally we summarize various factors that determine SF600-42/1380 generator main protection scheme of configuration.
