Problems solved by technology

The traditional calculation method does not consider the transfer of water kinetic energy and pressure energy in the reservoir, pressure diversion pipe, hydraulic turbine, and draft tube, so there is no targeted improvement on the structure and technology of the reservoir, pressure diversion pipe, hydraulic turbine, and draft tube and optimization, so that water energy is not fully and efficiently utilized

Embodiment Construction

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

[0060] Taking the pressure diversion pipe 2 with a caliber of 8m as an example, the flow velocity of the water 2 in the pressure diversion pipe for the turbine 3 is 8m / s. Without considering the change of the flow velocity after passing through the turbine 3 and the influence of other factors, if The diameter of the water inlet of the trumpet-shaped draft pipe 5 is 8m, and the diameter of the water outlet is twice the diameter of the pressure diversion pipe 2. Then, the trumpet-shaped draft pipe 5 flows through ...

Abstract

The invention discloses a method for generating power effectively by a hydroelectric generator and a system thereof, which is characterized in that the pipe diameter of a draft tube is more than that of a pressure water-conduit tube. By increasing the difference value of the water flowing speed of the pressure water-conduit tube and the draft tube, more kinetic energy component in the water energy is converted into electric energy, thus improving the power generation efficiency.

Description

technical field [0001] The invention relates to a high-efficiency power generation method and system for a hydroelectric generator, 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 interfa...
