    At Radisson, Bipole 1 uses a ground electrode of the same size and type as Dorsey, but only 11.2 kilometres (7.0 mi) away from the station at Bipole 2 uses a ground electrode 548 metres (1,798 ft) in diameter, and 11.2 kilometres (7.0 mi) from the Henday Converter Station 56°26′2″N 94°13′22″W  /  56.43389°N 94.22278°W  / 56 ...

  3. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.

  4. Francis turbine - Wikipedia

    en.wikipedia.org/wiki/Francis_turbine

    Francis type units cover a head range from 40 to 600 m (130 to 2,000 ft), and their connected generator output power varies from just a few kilowatts up to 1000 MW. Large Francis turbines are individually designed for each site to operate with the given water flow and water head at the highest possible efficiency, typically over 90% (to 99% [ 6

  5. Water turbine - Wikipedia

    en.wikipedia.org/wiki/Water_turbine

    The construction of a Ganz water Turbo Generator in Budapest in 1886. Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years.

  6. Screw turbine - Wikipedia

    en.wikipedia.org/wiki/Screw_turbine

    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.

  7. Capability curve - Wikipedia

    en.wikipedia.org/wiki/Capability_curve

    Due to flexibility allowed by the presence of the power converter, the doubly-fed and full-converter wind generators on the market have different shapes of the capability curve: "triangular", "rectangular", "D-shape" [7] (the latter one resembles the D-curve of a synchronous generator). The rectangular and D-shapes of the curve theoretically ...

  8. Taum Sauk Hydroelectric Power Station - Wikipedia

    en.wikipedia.org/wiki/Taum_Sauk_Hydroelectric...

    The pumped-storage hydroelectric plant was constructed from 1960–1962 and was designed to help meet daytime peak electric power demand. [8] It began operation in 1963. Electrical generators are turned by water flowing from a reservoir on top of Proffit Mountain into a lower reservoir on the East Fork of the Black River. At night, excess ...

  9. Pelton wheel - Wikipedia

    en.wikipedia.org/wiki/Pelton_wheel

    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 ]
