| Abstract: | This paper reviews the research work about the internal short circuit fault and the main protection schemes for large hydraulic generators and identifies the importance and major challenges in the research on the transient process in faulty conditions of the generators. The theory and validation of the simplified transient simulation model based on dual damper bars in each pole are presented. It is demonstrated that the simplified transient simulation model can meet the demand of practical applications with required calculation precision and solution speed. |
