Turbines, hydrodynamic screws, machine technology, hydraulic steelwork
F.EE hydropower works together on turbine and machine technology with renowned and proven partners. Close cooperation exists with manufacturers and specialists in turbines and hydraulic steelwork. As a general contractor, we can provide complete support to your hydropower project, e.g. the replacement of hydraulic turbine controllers. With projects in Rwanda, Africa, our general contractor assignment includes not only the turbines but also the erection of the entire infrastructure and structures.
Service spectrum in turbines and machine technology
Power station types:
Run-of-river plants, storage plants, pumped-storage plants.
- Water wheel
- Cross-flow turbines
- Francis turbines
- Kaplan turbines
- Pelton turbines
- VLH turbines (Very-Low-Head)
- Hydrodynamic screws
- Synchronous and asynchronous generators
- Constant and variable speed generators
VLH turbines (Very-Low-Head turbines) are an ecological technology in turbine development, which can be used in locations which were previously not economically or ecologically feasible. Since the market introduction of the turbine type in Germany, F.EE has been responsible for the superposed control at the locations realised to date, and is therefore able to specifically and comprehensively advise new customers, who are presently in the planning phase, on the new VHL turbine technology.
The concept of hydrodynamic screws is more frequently in use today than the relatively new VLH turbine technology. They are characterised in particular by their low sensitivity to level fluctuations and are especially kind to fish and other aquatic organisms. They can also be operated economically and with high levels of efficiency where gradients are minimal. Furthermore, the water engineering works are less complex than with run-of-river power plants with turbines. F.EE can also reliably implement general contractor assignments and inform customers of the possibilities and advantages of hydrodynamic screws during the planning phase.
Movable power plants
Movable power plants consist of a compact modular unit of internal Kaplan turbines with generator directly mounted on the turbine shaft. The mobile powerhouse can be subjected to over and under currents, and the complete structure blends harmoniously into the landscape. Due to the resultant ejector effect, it is possible to achieve 5 to 7 percent higher annual yields with mobile power plants than conventional power plants. Possible application areas also include weir systems with minimal gradients. Particular advantages, aside from the efficiency and the compact and inconspicuous structure, are the low operating noise and fish compatibility.
