PUMPING ACCUMULATION TIDE POWER PLANT, WITH MULTIPLE MODULES, AND CONSTRUCTION PROCESS OF THE SAME ON A TIDAL SITE

摘要

A tidal pumped storage power generation arrangement in a tidal bay leaves a tideway 1 extending from the mouth of the bay to the innermost end thereof, and comprises a waterway defining adjacent basins enclosed by barrages on the tideway side and at mutually adjacent sides with pump-turbines at the tideway side. The basins (4,8,9..) may be used for ebbtide power generation and basins (5,6,7...) for flood tide power generation. The water level of the basins is further elevated for ebbtide generation and further lowered for flood tide generation at night by using electric power from the national grid.
