Embodiment Construction

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

Abstract

The invention discloses a wind power boosting efficient hydroelectric generation method and a system. The method is characterized in that the pipe diameter of the draft tube is designed to be greater than the pipe diameter of the pressure water conduit; the externally added wind force supercharging device is utilized to pressurize the flow at the inlet of the pressure water conduit of a reservoir, thus increasing the quantity of the electric energy which is transformed by the kinetic energy and the pressure energy of the hydraulic energy, improving generating efficiency and improving the utilization ratio of the hydraulic energy.

Description

technical field [0001] The invention relates to a method and system for wind boosting and high-efficiency hydropower generation, 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 interface ...
