Definitions
- the invention relates to a hydroelectric power plant with a turbomachine, in particular a water turbine, further comprising an electric generator which is driven by the turbine.
- Hydropower plants have become known in various forms. These include, for example, river power plants, which exploit the energy of the flow of the river. Furthermore, storage power plants have become known. These include an upper water storage and an underwater storage. Between these two the machine set is arranged, consisting of a turbine and a generator. The turbine can be operated at pumped storage plants at times of low energy demand as a pump. It then conveys a part of the water contained in the underwater tank back into the upper water tank.
- Turbi ⁇ enart except free-jet turbines come into consideration.
- Francis turbines for example, Francis turbines, semi-axial or Kaplan turbines.
- the rotor of the turbomachine, for example the turbine, and the rotor of the generator have one and the same shaft, but may also have separate shafts.
- the turbine is preceded by a downpipe.
- the turbine generally includes a helical inlet housing that directs the water at the blades of the turbine rotor.
- the turbine is connected downstream of a suction pipe. This is directly connected to the spiral housing. In general, it widens funnel-shaped in the flow direction. It opens below the underwater mirror.
- Hydropower plants with two turbines connected in series are known. See CH 28 31 84 A and CH 126465 A.
- these hydroelectric plants have disadvantages. Thus, they do not function as desirably to reduce the risk of cavitation. In addition, they are expensive and expensive to manufacture.
- the invention has for its object to design a hydropower plant of the type described above such that the Kavitationsgefahr reduced and At the same time, the construction costs associated with a large setting are reduced.
- the inventor has found the following solution: He provides in the flow path before two turbines, which are connected in series.
- the first turbine seen in the flow direction is a radial, semi-axial or axial flow turbine.
- the second turbine seen in the flow direction is a radial, semi-axial or axial flow turbine.
- the first turbine may be a Francis turbine
- the second turbine may be a Kaplan turbine.
- the two turbines directly downstream of each other, thus without interposed choke or without switched between water lock.
- the axes of rotation of the rotors of the turbines can be arranged at the same geodetic height. However, deviations are possible. After all, more than two turbines can be combined.
- the invention can be used with particular advantages at high slopes and in applications where small diameter turbines are preferred, for example for environmental reasons.
- Underwater mirror can be arranged. Due to the flow resistance, it is also possible to freely choose the speed.
- the invention is also applicable to pumped storage plants.
- Figure 1 shows schematically a hydropower plant with a Francis turbine and a downstream Kaplan turbine.
- FIG. 2 shows an axial section of a Francis turbine with a horizontal shaft and with a downstream further turbine.
- Figure 3 shows schematically a Francis turbine with vertical shaft and downstream further turbine.
- FIG. 4 schematically shows a Kaplan turbine with vertical shaft and downstream further turbine.
- FIG. 1 illustrates the basic principle of the invention.
- the hydropower plant shown therein comprises an upper water 10. This fed by a Pressure line 20 via a shut-off 30 a Francis turbine 1.
- the Francis turbine 1 drives a generator 40 at. After passing through the turbine, the water flows through a second turbine 50 to the underwater 60.
- FIG. 2 shows a Francis turbine 1 with a horizontal shaft. It comprises the following essential elements: a rotor 2 with a plurality of blades 2.1, a volute 3 enclosing the rotor 2, a shaft 4 rotatably connected to the rotor 2 and arranged horizontally, a draft tube 5 with a manifold expanding spout 5.2.
- the turbine drives during operation to a generator, not shown here. Its rotor also sits on shaft 4.
- FIG. 3 again shows a Francis turbine 1. However, this has a vertical shaft 4.
- the Francis turbine 1 is followed by a second turbine, which is located in the intake manifold 5, but not shown here.
- the turbine 1 shown in FIG. 4 is a Kaplan turbine. It has a vertical shaft 4.
- this turbine is a second turbine downstream, not shown here.
