Andritz Green, Fishfriendly Kaplan Technology Basics of Water Filled Runner Design

Xayaburi, Laos: overall fish friendly conceptual design Up and down fishpassage and fishfriendly turbines Fischaufstieg (gewässeraufwärtsgerichtete Wanderung) Fischaufstiegshilfen und -anlagen Fischabstieg (gewässerabwärtsgerichtete Wanderung) Fischfreundliche Turbine Fischabstiegshilfen, sogenannte Bypässe www.andritz.com

Risks on passing through a Water Turbine 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 * Rodrigue, P., “Fish Friendly Turbines – Do They Work?”, Acres International, April 2005. www.andritz.com

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 www.andritz.com

TECHNOLOGY LEADER IN OIL FREE KAPLAN RUNNER TECHNOLOGY Oil Free Kaplan Runners - References References: > 100 Units above 5 MW Majority in Scandinavia First runner Bruksfallet 1993 Max. runner dia. 7.525 m Max. head 57.8 m Max. output 86 MW TECHNOLOGY LEADER IN OIL FREE KAPLAN RUNNER TECHNOLOGY www.andritz.com

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 Hub Water River water www.andritz.com
