This presentation summarizes an industrial internship at the Mahi Hydel Power House-1 in Rajasthan, India. It provides details about the power station, including its capacity of 140MW generated by two 25MW Francis vertical shaft turbines. It describes the key components of the power generation process, including the penstock that carries water to the turbines, the spiral casing and guide vanes that direct water to the runner blades, the draft tube, bearings, governing equipment, auxiliary systems, generators, transformers, and maintenance procedures. The internship provided valuable practical experience in understanding how hydroelectric power plants operate and the importance of efficiently planning and managing their complex systems.
