Embodiment 1

[0024] As attached figure 1 As shown, the siphon-type multi-stage hydroelectric power generation method of the present invention first selects a section of the river basin 1 with a water flow drop, and installs the water inlet end of the siphon pipe 2 in the upper water area of ​​the water flow drop. The water flow drop section is laid, and the water outlet end of the siphon pipe 2 is introduced into the lower water area of ​​the water flow drop section or other discharge places; a set or a set of pipe sections where the water flow pressure difference of the siphon pipe 2 reaches the power generation speed requirements of the hydro-generator set In the above-mentioned hydro-electric generator sets 3, each hydro-electric generator set 3 is connected to the parallel control system 4. The parallel control system 4 includes a flow control unit, a flow rate control unit, and a pressure difference control unit. The control units work in coordination to make the hydraulic turbine gener...

Embodiment 2

[0027] As attached figure 2 As shown, the siphon-type multi-stage hydroelectric power generation method of the present invention first selects a section of the river basin 1 with a water flow drop, and installs the water inlet end of the siphon pipe 2 along the upper water area of ​​the water flow drop section. Following the laying of the water flow drop section, the water outlet end of the siphon pipe 2 is introduced into the lower water area of ​​the water flow drop section or other discharge places; a set of pipe sections or pipe sections where the water flow pressure difference of the siphon pipe 2 reaches the power generation speed requirements of the hydro-generator unit 3 There are more than one group of hydroelectric generator sets 3, and each hydroelectric generator set 3 is connected to the parallel control system 4. The parallel control system 4 includes a flow control unit, a flow rate control unit, and a pressure difference control unit. The control units work in ...

Abstract

The invention provides a hydrocone type multi-stage hydroelectric generation method and belongs to the technical field of hydroelectric generation. The method comprises the following steps of: firstly, selecting one section of river basin with a flow fall, installing a water inlet end of a siphonage pipeline on the upper end of water area of the flow fall section, laying the siphonage pipeline along the flow fall section, intruding a water outlet end of the siphonage pipeline into the lower end of water area of the flow fall section or other discharge regions; and arranging one or more water-turbine generator sets in a pipe section where the flow pressure difference of the siphonage pipeline reaches the requirement of the rotating speed of the water-turbine generator sets, wherein each water-turbine generator set is connected with a parallel operation control system. The method provided by the invention has the advantages of low engineering cost, little limit to regions, no need of building a dam on a river, large flexibility in arranging the generator sets, no damage and pollution to environments, lower operation cost, stable flow speed, and more suitability of being built in the river basin with the flow fall. The water outlet end of the siphonage pipeline can be used for supplementing a water source for a lake and a reservoir, can also be used for supplementing water for a water-deficient area, a dry river and a farmland, and plays a role in improving environment and farmland soil.

Description

(1) Technical field [0001] The invention relates to a hydroelectric power generation technology, in particular to a siphon type multi-stage hydroelectric power generation method. (2) Background technology [0002] Hydropower is a renewable energy source.
