METHOD OF ENHANCING POWER CAPACITY OF PUMPED-STORAGE POWER PLANT

摘要

The invention relates to hydraulic structures and can be used in the construction and reconstruction of a pumped storage plant (PSPP). The purpose of the invention is to reduce the amount of construction work and material consumption. The complex of the power plant contains the upper bass. Sein 1, pressure shaft 2, power plant building 3, lower sealed pool 4, ventilation drift 5, airtight hatch with a check valve 6. The increase in the energy capacity is performed as follows. First, the lower basin 4 is filled with water, it is sealed and the water is pumped from the lower basin 4 to the upper basin 1. At the same time, as the volume and water level in pool 4 decreases, a vacuum will be created in it. When the power plant is turned on in the generator mode, the total pressure on the hydraulic unit will be equal to the sum of the static pressure and the increment obtained as a result of creating a vacuum on the surface of the water in the lower pool of 4. 1 Il.
