Turgo turbine and generator At Milford Sound, New Zealand. The Turgo turbine is an impulse water turbine designed for medium head applications. Operational Turgo turbines achieve efficiencies of about 87%. In factory and lab tests Turgo turbines perform with efficiencies of up to 90%. It works with net heads between 15 and 300 m. [1]
The plant is located inside the Ohio Natural Wildlife Conservation Area and is considered a large impoundment hydro power plant. [3] The station was built after a canal and dam within the Ohio river in an attempt to allow boats to navigate the 8 ft vertical drop among the falls that spanned 2 miles wide. Production of the canal and dam began in ...
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
S-turbines eliminate the need for a bulb housing by placing the generator outside of the water channel. This is accomplished with a jog in the water channel and a shaft connecting the runner and generator. The VLH turbine is an open flow, very low head "kaplan" turbine slanted at an angle to the water flow. It has a large diameter >3.55 m, is ...
The Henry M. Jackson Hydroelectric Project, or Jackson Hydro Project, is an electric power generating project on the Sultan River operated and maintained by the Snohomish County Public Utility District in Washington, co-licensed by the city of Everett, Washington. [1]
A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes. In 1819 the French engineer Claude Louis Marie Henri Navier (1785–1836) suggested using the Archimedean ...
A wheel power divided by the initial jet power, is the turbine efficiency, η = 4u(V i − u)/V i 2. It is zero for u = 0 and for u = V i . As the equations indicate, when a real Pelton wheel is working close to maximum efficiency, the fluid flows off the wheel with very little residual velocity. [ 11 ]
As of 2025, plans exist in the Democratic Republic of the Congo for the construction of a hydroelectric power station set to overtake the Three Gorges, [3] with an installed capacity of 39,000 MW. [ 4 ] [ 5 ] The Project is called Grand Inga and is planned to be realised on the lower Congo River . [ 6 ]
