Embodiment Construction

[0023] After the power inputted by the power cable (11) is transformed in voltage and phase, it is connected to the pump room (5), and part of the water behind the dam (3) is directly pumped back to the front of the dam of the original reservoir by various pumping equipment, and the water is connected to the front of the dam. The water (1) is completely fused, and the water behind the dam (3) after pumping back flows together with the water in front of the dam (1), causing two major changes: First, the amount of incoming water available for power generation increases, which can directly increase power generation The second is to increase energy resources such as kinetic energy, potential energy and pressure energy of the water in front of the dam (1) after the new fusion. If it is used for generator power generation, the generator speed can be increased. According to the needs of various aspects, the gravitational potential energy of the water in front of the dam after fu...

Abstract

In the invention, for the power needing energy storage, by utilizing various equipment and facilities of a hydraulic power station and building various pumping equipment and facilities, part of water behind the dam of the hydraulic power station is pumped to flow back to the region ahead the dam of the original reservoir, thereby achieving the purpose of energy storage. Energy resources such as kinetic energy, potential energy, pressure energy and the like generated by the newly mixed water ahead the dam are converted into the mechanical energy of generating equipment and then converted into stable electric energy to be sent out through the network. By establishing a great electric energy storage platform for combining a plurality of reservoirs and stations with other hydraulic power stations, the invention can effectively solve the problem of energy storage of power and especially green power, thereby promoting the healthy development of the green power in larger scale, higher speed and wider range. Moreover, an extra-high voltage power transmission technology, a smart grid technology and other related technologies are used for realizing a good situation of adjustable, controllable and sustainable power generation, power storage, power utilization and power transmission and transformation, thereby providing services for economic and social development.
