Abstract :
Reliability analysis for hydro power stations for (N+M) and 2N fault tolerant modes (FTM) and their comparison from the standpoint of control and maintenance have been carried out in this paper. It shows that the (N+M) FTM is superior to 2N FTM in reliability and economics in most cases. So, (N+M) FTM is recommended for large power stations, especially for multiunit plants. A simple method for choosing the number of standby controllers is developed by optimizing the (N+M) FTM. The ideas and results proposed in this paper can be used not only for goveming systems in hydro power stations but also for other industrial systems.
