Electricity Knowledge Sharing:Turbines For Different Type Of Hydropower Stations

September 17, 2021

Latest company news about Electricity Knowledge Sharing:Turbines For Different Type Of Hydropower Stations

Turbine type according to available head

Turbines convert the energy of rushing water, steam or wind into mechanical energy to drive a generator.

The generator then converts the mechanical energy into electrical energy. In hydroelectric facilities, this

combination is called a generating unit.

 

Francis turbine

The most commonly used turbine in hydropower system. Water strikes the edge of the runner, pushes the blades

and then flows toward the axis of the turbine. It escapes through the draft tube located under the turbine. It was

named after James Bicheno Francis (1815-1892), the American engineer who invented the apparatus in 1849.

Kaplan turbine

Austrian engineer Viktor Kaplan (1876-1934) invented this turbine. It's similar to the propeller turbine, except

that its blades are adjustable; their position can be set according to the available flow. This turbine is therefore

suitable for certain run-of-river generating stations where the river flow varies considerably.

Propeller turbine

Since they can reach very high rotation speeds, propeller turbines are effective for low heads. Consequently,

this type of turbine is suitable for run-of-river power stations.

Pelton turbine

Named after its American inventor, Lester Pelton (1829-1908), this turbine uses spoon-shaped buckets to harness

the energy of falling water.
