Critical speed calculation of a refurbishment of 11MW hydro power plant unit

Hydro generator design is a significant issue in terms of safety, efficiency, and energy production sustainability. One the most crucial issues about criteria to satisfy needs project?s critical speed. In this work, speed calculation an 11 MW hydro power plant was investigated with several steps. Numerical solution methodologies were implemented using ARMD?. A developed, implementation rotor carried out Antalya, Turkey. Vibration displacements are adequate. The unit active for 3 years have never encountered runaway speeds. No or resonance anticipated designed unit.
