Medium-sized pumped storage power station

What is pumped storage power station?

Small and medium-sized pumped storage power stations are mainly used to store clean energy such as wind and solar energy. Pumped storage has the characteristics of flexible operation and low environmental pressure, so it is a mature energy storage method with high economy and large capacity .

Why are small and medium-sized pumped storage power stations important?

Small and medium-sized pumped storage power stations have unique development advantages, and the development and construction of small and medium-sized pumped storage power stations have important practical significance for optimizing the energy structure of Zhejiang Province.

What is pumped storage?

Pumped storage is the regulating power source of clean energy in the electric power system. With the continuous promotion of the dual-carbon strategy goal, governments are actively planning and constructing pumped storage power stations, which have shown a spurt of development.

Are pumped storage power stations reversible?

Small and medium-sized pumped storage power stations can be reversible mixed-flow, reversible cross-flow, or individual motor-pumped, four-unit split, three-unit series, and two-unit reversible, and can be developed in the high, medium, and low-head range to avoid frequency switching start-up.

What are the advantages of pumped storage power stations?

Moreover, compared to other forms of energy storage, small and medium-sized pumped storage power stations have long service life, long equipment service cycles and little environmental damage.

When did pumped storage power stations start?

The construction of early pumped storage power stations at home and abroad started from small and medium-sized power stations. In the 1960s, the construction of Hebei Gangnan small hybrid pumped storage power station with an installed capacity of only 11,000 kW filled the gap in China's pumped storage industry.
