The Okukiyotsu No. 2 Hydro Project (extention of existing Okukiyotsu Pumped Storage) is now under construction in Japan. Two generating units of 300 MW are being installed in a new powerstation adjacent to the existing powerhouse. Remarkable design features are applied to No. 2 unit of the new project to realize the 300 MW class adjustable-speed pumped storage with AC excitation system of GTO (Gate Turn Off thyristor). This paper describes the project, mainly focuses on the electrical equipment for adjustable-speed operation by double-fed generator-motor with GTO Inverter-Converter in pumped storage.
