The Tadami Hydro-electric Power Project (Tadami Project) of the Electric Power Development Co., Ltd. (EPDC) - Japan is now under construction and is scheduled to be in commercial operation in August, 1989. Bulb turbine generating units are considered to be one of the most appropriate solutions for economical development of such low-head hydroenergy as 20 m. The 65.8 MW bulb generating unit, the world's largest in capacity, manufactured by Hitachi, Ltd. - Japan, was adopted for the Tadami Project. Prior to the manufacturing of the prototype machine, extensive model tests, as well as extensive computer simulations, were carried out to ensure its high performance and reliability. The project profile, features of turbine and generator design, model tests results, and other features of the project are presented in detail.
