Protection of Fish
Risks on passing through a Water Turbine
Mechanical Effect (4.3 %*)
Collision with Turbine blades
Squeezing at gaps
Skimming at surface
Hydraulic Effects (0.6%*)
Pressure rise
Cavitation
Shearing of tension
Turbulence
Other fish and animals and humans (2%*)
Starke Druckwechsel
Schwimmblase von Fischen könnte implodieren bzw. explodieren
Kavitation
Implodierende Kavitationsblasen an der Fischhaut kann diese verletzen
Fischfreundliches Design:
CFD (computerunterstütze Strömungsberechnung) dient als Werkzeug einen gleichmäßigeren Druckwechsel auf dem Laufrad zu bekommen und Kavitation zu vermeiden.
Turbulenzen
Kleine Turbulenzen  mögliche Prellungen
Große Turbulenzen  Orientierungslosigkeit und Verlust des Gleichgewichtes führt zu reduzierter Schwimmfähigkeit
 erhöhte Anfälligkeit für Raubtiere
Scherspannungen
Hohe Scherspannungen im Stütz- Leitapparat und in der Nähe der Laufschaufeln  führt zu Streckungen, Komprimierungen und Verdrehungen des Fischkörpers
Moderne „high performance“ Kaplan verursachen geringe Turbulenzen  höhere Überlebensrate von Fischen  geringere Lärmentwicklung
 geringere Energieverluste

11. Fischfriendly Technology
Measures taken today
Optimisation of the plant concept
Layout of turbine type, number of blades, RPM, Diameter
Number of Turbines, operating regime
Example Xayaburi: 5 Blades ( not 6 ), 83.33rpm, D = 8.6 m
Calculation and Optimisation of fish friendliness
CFD based BIO PA (Biological Performance Assessment)
Optimisation of flow conditions by adapting turbine geometry
E.g.: Priest Rapids Bio PA
Fishfriendly turbine design
Blades: minimum gaps (Balldesign of Hub)
Guidevanes: reducing overlapping
Optimisation of turbine flow design
E.g.: Rock Island

12. TECHNOLOGY LEADER IN OIL FREE KAPLAN RUNNER TECHNOLOGY
Oil Free Kaplan Runners - References

TECHNOLOGY LEADER IN OIL FREE KAPLAN RUNNER TECHNOLOGY

13. Oil Free Kaplan Runners – Water Filled Hub
ENVIRONMENTALLY SAFE
No risk of oil leakage into the river water
Hub filled with water + corrosion inhibitor (lemon acid)
Blade seal arrangement prevents water exchange
Volume compensation
