Problems solved by technology

[0006] 2. When the hydraulic turbine is running, half of its blades will form a reverse flow, which will have an adverse effect on the turbine and reduce the working efficiency of the hydraulic turbine, thereby also affecting the efficiency of the whole unit
[0008] However, in the above-mentioned continuous unit hydroelectric power generation system, if the dam type is high enough, especially for a super power station with a water storage elevation above 270m, the super pressure of the falling water body will easily destroy the unit at the front end of the water channel, and at the same time, the water body under the diversion section of the water channel is still There is a lot of potential energy, but it is not fully utilized

Embodiment 1

[0034] The integrated hydroelectric power generation system includes units of three power generation modes of "circulation type", "confluence type" and "flow diversion type" arranged in sequence from upstream to downstream. The units of the three power generation modes share a waterway and operate simultaneously to generate electricity. This power generation mode is suitable for ultra-high dams with water storage elevations above 270m and large-flow hydropower stations. Through scientific layout, resources are integrated to ensure that the units of the three different power generation modes can meet their required flow and pressure requirements. The huge hydraulic potential energy can be converted into electrical energy to the greatest extent and with the highest efficiency.

Embodiment 2

[0050] Figure 7 The schematic diagram of the integrated hydroelectric power generation system provided for this embodiment is basically the same as that of Embodiment 1, the difference being that a waterway buffer zone 2-4 is provided on the extension line at the end of the middle section of the waterway 2-2. After the water flow pours down from the middle section 2-2 of the water channel, part of the water falls directly from the water channel diversion section 2-3, and part of the water flows down from the water channel diversion section 2-3 after being buffered by the water channel buffer zone 2-4.

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that: from the upstream to the downstream, only the units of the "circulation type" and "confluence type" power generation modes are arranged in sequence, and the units of the two power generation modes share a waterway and run simultaneously to generate electricity.

[0053] Although the utilization rate of water energy in this way is lower than that of Embodiment 1, it is still higher than that of the traditional hydroelectric power generation system.

Abstract

The invention provides a comprehensive hydraulic power generation system. A water channel is composed of a water channel inlet section, a water channel middle section and a water channel drainage section which are sequentially connected and incline downwards. The inclination of the water channel middle section is smallest, a power generator set B is arranged in the water channel middle section, and a power generator set A is arranged on the upstream part of the power generator set B. A power generator set C is arranged in the water channel drainage section. The power generator set A, the power generator set B and the power generator set C share the same water channel. The power generator set A can be located either outside a hydropower station dam body or inside the dam body. Resources are integrated through a scientific layout, the three power generator sets with different power generation modes can all meet the requirements for flow and pressure, and powerful hydraulic potential is converted into electricity to the maximum extent highly efficiently. The comprehensive hydraulic power generation system is simple in structure, reliable in performance, high in work efficiency and high in power generation efficiency, the installed capacity and the hydroenergy utilization rate are maximized, and the comprehensive hydraulic power generation system is particularly suitable for an ultra-high dam and large-flow hydropower station with the water elevation more than 270 m.

Description

technical field [0001] The invention relates to a hydropower generation system, in particular to an efficient and comprehensive hydropower generation system suitable for super-high dam type hydropower stations. Background technique [0002] Hydroelectric power is the use of rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use the water turbines as the driving force to drive generators to generate electricity. [0003] Traditional hydroelectric power generation systems such as figure 1 As shown, a water channel 2 is provided in the dam body 1 of the hydropower station, the top entrance of the water channel 2 is the water inlet 3, a columnar valve 4 is provided in the water channel 2, and a hydraulic turbine 5 is provided at the bottom of the water channel 2, and the hydraulic turbine 5 is connected to the generator 6. When working, open the colu...
