A Bonneville Dam Kaplan turbine after 61 years of service. The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, [1] who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level.
Kaplan turbine: This turbine is a propeller-type turbine which has adjustable blades to achieve efficiency over a wide range of heads and flows. The Kaplan can be used at low to medium heads (1.5–20 metres) and medium to high flows (3 m 3 /s–30 m 3 /s). For higher flows multiple turbines can be used.
Kaplan turbine and electrical generator cut-away view. The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are ...
In June 2012 a third Kaplan turbine-generator, rated at 24 MW, was commissioned. In January and June 2013, the original two 20 MW Kaplan turbine-generators were upgraded to 24 MW each. In January and June 2013, the original two 20 MW Kaplan turbine-generators were upgraded to 24 MW each.
Rainpower AS is a Norwegian company which develops, designs, manufactures and sells equipment for hydropower electricity generation. The company provides Pelton, Francis, and Kaplan turbines, as well as pump turbines, small hydropower plants, turbine governor, oil pressure systems, valve controllers, exciters, valves, gates, pipes, and other products and services related to the hydropower ...
Between 1967 and 1971 a Kaplan turbine was built, adding another 110 MW, and it now operates at an installed capacity of 215 MW, with an average annual production of 1,275 GWh. [2] In 2015 the construction of a twelfth turbine began on the south side of the dam. This is also a Kaplan turbine rated at 128 MW. The new turbine will allow the ten ...
The power station at the Moses-Saunders Dam contains 32 turbine generators. Ontario Power Generation operates units 1-16 and the New York Power Authority operates 17-32. The Canadian side of the power station, R.H. Saunders Generating Station, contains 16 x 65.3 MW fixed-pitch Kaplan turbine -generators and the U.S. power station, St. Lawrence ...
A Kaplan turbine has fewer runner blades than a Francis turbine because a Kaplan turbine's blades are twisted and cover a larger circumference. Friction losses in a Kaplan turbine are less. The shaft of a Francis turbine is usually vertical (in many of the early machines it was horizontal), whereas in a Kaplan turbine it is always vertical. A ...
