2. Engine–generator - Wikipedia

   en.wikipedia.org/wiki/Engine–generator

   An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...

3. Turbo generator - Wikipedia

   en.wikipedia.org/wiki/Turbo_generator

   A turbo generator is an electric generator connected to the shaft of a turbine (water, steam, or gas) for the generation of electric power. [note 1] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships. [1] Small turbo-generators driven by gas turbines are ...

4. Hydrogen-cooled turbo generator - Wikipedia

   en.wikipedia.org/.../Hydrogen-cooled_turbo_generator

   The generators produce high voltage; the choice of voltage depends on the tradeoff between demands of electrical insulation and handling high electric current. For generators up to 40 MVA, the voltage is 6.3 kV; large generators with power above 1000 MW generate voltages up to 27 kV; voltages between 2.3 and 30 kV are used depending on the size ...

5. Dynamo - Wikipedia

   en.wikipedia.org/wiki/Dynamo

   "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...

6. Doubly fed electric machine - Wikipedia

   This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked to the speed of the power grid and cannot speed up. So large forces are developed in the hub, gearbox, and generator as the power grid pushes back.

7. Electric generator - Wikipedia

   It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.
