Old Pelton wheel from Walchensee Hydroelectric Power Station, Germany. The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot ...
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...
Lester Allan Pelton (September 5, 1829 – March 14, 1908) was an American inventor who contributed significantly to the development of hydroelectricity and hydropower in the American Old West as well as world-wide. In the late 1870s, he invented the Pelton water wheel, at that time the most efficient design of the impulse water turbine.
Used as a generator, it produced 3000 volt, 133 Hertz, single-phase AC. It was driven by a six-foot Pelton wheel under a 320-foot (98 m) head of water carried in a 2 ft diameter steel pipe supplied by the Howard Fork and Lake Fork as well as natural reservoirs up hill from the plant. [5]
Third, it has higher specific speed and can handle a greater flow than the same diameter Pelton wheel, leading to reduced generator and installation cost. Turgos operate in a head range where the Francis and Pelton overlap. While many large Turgo installations exist, they are also popular for small hydro where low cost is very important.
The Rubicon Hydroelectric Scheme is a small run-of ... The Rubicon Power Station has two 4.6-megawatt (6,200 hp) horizontal single-jet Pelton wheel generators. [1 ...
The power house originally had 11 Pelton turbines made by Escher Wyss (Zürich). Each turbine was coupled to two 1,000 kW DC generators made by Dick, Kerr & Co., which powered the smelting process. There were also two AC generators for auxiliary power. [6] The annual output of the hydroelectric scheme reached 160 GWh, a load factor of over 80%.
In India, hydro projects up to 25 MW station capacities have been categorized as Small Hydro Power (SHP) projects. [6] Small hydro can be further subdivided into mini hydro, usually defined as 100 to 1,000 kilowatts (kW), and micro hydro which is 5 to 100 kW. Micro hydro is usually the application of hydroelectric power sized for smaller ...
