Micro Hydro Power. A Solution for Thailand.
Micro Hydro Power. OUTLINE Problem & Consequences The Solution Finance Summary Reference
Problem. Large Hydro Power Systems - generate water pressure - propell downstream high speed turbines - cutting the water stream
Problem. Current Small Hydro Power Systems do the same with smaller technology.
Problem. Many Micro Hydro Power Systems do the same with even smaller technology.
Consequences. • - high water flow rate necessary (m/sec) • high hight difference necessary (m) • high turbine rotation (rpm) • water quality depletion (cod/bod/pH) • high water accidity = high corrosion • natural water stream is cut • negative impact on animal population • upstream and downstream effects • often clogged or damaged by debris

TheEffect. Gravitational Water Vortex.
The Solution. Gravitational Water Vortex Power.
The Solution. Gravitational Water Vortex Power.
The Solution. Gravitational Water Vortex Power. • - 1.2 m hight difference • 1 m3 / sec. continuous • 12 kW hydraulic capacity • 6.2 kW generator output • 0.9 Capacity Utilization • 50 MWhel / year • free water aeration • fish unharmed
The System. Power Generation Water In Water Out
The Pilot Plant. Schoeftland / Switzerland.
Solution. Gear Box Generator Control Cabinet Rotor
The Pilot Plant. Capacity: 30 kW Grid Export: 263 MWh p.a. Diameter: 6.5 m Water Flow: 0.8 - 2.5m3/s Hight Difference: 1.7m Turbine Frequency: 21 rpm Concrete used: 65 m3 Steel used: 4 t Components: Rotor, Control Cabinet, Gear Box, Generator Features
The Solution. Direct Instream System - 10 - 150 kW - low water flow – only 2-3m/sec - low hight difference – from 0.7m - low turbine rotation – max.60rpm - water quality melioration - low cod/bod, optimum natural pH - fish can pass unharmed up/downstream - debis can pass without damage or clogging
The Solution. New Effect: Gravitational Vortex Certified by SGS 50 kW 90% Availability Water Vortex Power Plant 50 kW 2-3 m/sec 0.7 m Natural COD/BOD/pH Fish Population Unharmed
Micro Hydro Power. FEATURES High Adaption to Local Condition Low Water Input Necessary Low CAPEX & OPEX High Power Output High Capacity Utilization Environmental Impact Positive
