Water storage power generation system using seabed pressure energy

Abstract

The invention discloses a water storage power generation system using seabed pressure energy. The power generation system comprises a storage container, a seawater pumping energy accumulation unit and a pressure pipe; the storage container is arranged on a seabed, and includes a first opening end; the first opening end is connected to the pressure pipe; a valve is arranged on the pressure pipe; and the seawater pumping energy accumulation unit is arranged on the seabed, is connected to the pressure pipe, and includes fluid machinery connected with the pressure pipe and a motor / generator in transmission connection with the fluid machinery. The power generation system realizes electric energy storage by using a pressure difference in the seabed and the storage container without constructing high and low impounding reservoirs and being limited by geographical conditions; and the system uses seawater as a working medium for solving the dependency problem of traditional water pumping energy accumulation on fresh water resources. The system is suitable for power supplies with various types, environment-friendly and broad in application prospect.

Problems solved by technology

However, the traditional pumped storage system needs special geographical conditions to build two storage tanks, the initial investment is huge, and the construction period is long (generally about 5-15 years).

In addition, the traditional pumped storage system uses fresh water as the operating fluid, and the system relies heavily on fresh water resources, which is less applicable to some island countries and cities where fresh water resources are scarce.
