Siphon hydroelectric generation system for high dam hydropower station

Abstract

The invention discloses a siphon hydroelectric generation system for a high dam hydropower station. The siphon hydroelectric generation system comprises a main dam body, wherein a water inlet channel is fixedly arranged at one side of the main dam body and a water outlet channel is fixedly arranged at the other side; a first intermediate channel is arranged in the main dam body; a second intermediate channel and a third intermediate channel are arranged in the main dam body; the water outlet channel is provided with a first water outlet channel and a second water outlet channel; and a first vacuum pump is fixedly arranged on the outer surface of the first water outlet channel. Elevation water stored in a reservoir is quickly absorbed into the water inlet channel by using the water pressure of the reservoir and the differential pressure in the vacuumed water inlet channel to flow into the water outlet channel for siphon hydroelectric generation. An existing siphon hydroelectric generation system for the high dam hydropower station is improved, and the waterpower utilization rate of the high dam hydropower station is effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of research on the hydropower utilization rate of high-dam hydropower stations, in particular to a siphon type hydropower generation system for high-dam hydropower stations. Background technique [0002] Gaoba hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. It is generally composed of reservoirs formed by water-retaining and discharge structures, water diversion systems of hydropower stations, power plants, and electromechanical equipment. Through the high-level water of the Gaoba Hydropower Station reservoir through the water diversion system, the continuous generator set of the hydraulic turbine is driven to produce electricity, and then it is input into the grid through the step-up transformer, switch station and transmission line for other equipment. [0003] For high-dam hydropower stations, such as the Three Gorges Hydropower Station on ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the defects that the hydroelectric power generation system adopted by the Gaoba Hydropower Station in the prior art has a low water energy utilization rate and cannot fully convert water energy into electric energy. The hydroelectric power generation system can effectively improve the water energy utilization rate of the existing high dam hydropower station
