Embodiment Construction

[0059] As shown in the figure, 1 is a reservoir, 2 is an external power booster, 3 is a pressure diversion pipe, 4 is a water turbine, 5 is a generator, and 6 is a draft tube. The external power supercharging device 2 is directly connected with the reservoir 1, the water inlet of the pressure diversion pipe 3 is connected with the external power supercharging device 2, and the water outlet of the pressure diversion pipe 3 is connected with the water inlet of the water turbine 4. The water outlet of the water turbine 4 is directly connected with the water inlet of the large-diameter draft tube 6 .

[0060] Taking the pressure diversion pipe 3 with a diameter of 8m as an example, for the water turbine 4, if the water flow velocity of the pressure diversion pipe 3 is 8m / s, without considering the change of the water flow velocity after passing through the water turbine 4 and the influence of other factors, If the diameter of the draft pipe 6 is twice the pipe diameter of the pres...

Abstract

The invention discloses a waterflow boosting high-efficiency hydropower method and a waterflow boosting high-efficiency hydropower system, which are characterized in that: the pipe diameter of a draft tube is designed to be greater than that of a pressure diversion pipe; and an additional supercharging device pressurizes waterflow at the inlet of the pressure diversion pipe of a reservoir so as to increase a component for converting kinetic energy and pressure energy into electric energy, improve generating efficiency and improve utilization efficiency of hydraulic energy.

Description

technical field [0001] The invention relates to a high-efficiency hydropower generation method and system for water flow pressurization, belonging to the field of hydropower generation. Background technique [0002] Hydropower stations use reservoirs to store water. The larger the storage capacity of the reservoir, the greater the amount of water stored, and the more water energy stored in the reservoir. A water flow with a certain flow velocity contains kinetic energy, and the higher the flow velocity, the greater the kinetic energy; a water flow at a certain height has potential energy, and the greater the relative height, the greater the potential energy. The water flows from a high place to a low place, which can convert potential energy into kinetic energy, and the water flow obtains a higher speed. The water stored in the reservoir acquires a high velocity under the action of gravity, is transported downward along the penstock, and acquires a higher velocity at the in...
