Design Requirements of Generators Applied to Low-Head Hydro Power Plants

Hydropower has long been recognized as a renewable power source. Due to economic reasons, high and medium head potentials have been primarily developed. Later, low-head potentials became a feasible solution with the application of modern Bulb generators. Although Bulb generators have been developed and applied since the 1930s, new techniques and materials have been used to overcome technical and design challenges, which are described herein.
