Abstract: Through the localization and independent research on pumped storage units, China has mastered the technology of pumped storage units of water head below 500 meters and rotating speed of 500 r/min.In order to make a breakthrough in the independent design and manufacturing technology of pumped storage units with high water head over 600 meters and high speed of 500 r/min, we illustrate the development and engineering application of Jixi Pumped Storage Unit, the first homebred developed unitswith high head and high speed over 600 meters in China, introducing the reasonable technical specifications for domestic units with high head.During the developing process, we adopted the mode of comparative test on the same platform to promote the hydraulics research and technology of the domestic units, and adopted innovative technologies such as “5+5” long and short blades of the unit.The test results show that the main performance indices of the unit are superior to the technical specifications.The research results can provide reference for the construction of other high head and high speed pumped storage power stations in China, and play an important role in promoting the technical progress of pumped storage units in China.
