  3. 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 ...

  4. Doubly fed electric machine - Wikipedia

    en.wikipedia.org/wiki/Doubly_fed_electric_machine

    Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines , because wind speed can change suddenly.

  5. Diesel generator - Wikipedia

    en.wikipedia.org/wiki/Diesel_generator

    A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]

  6. Capability curve - Wikipedia

    en.wikipedia.org/wiki/Capability_curve

    Due to high cost of a generator, a set of sensors and limiters will trigger the alarm when the generator approaches the capability-set boundary and, if no action is taken by the operator, will disconnect the generator from the grid. [3] D-curve expands with cooling. The D-curve for a particular generator can be expanded by improved cooling.

  7. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

  8. List of hydroelectric power station failures - Wikipedia

    en.wikipedia.org/wiki/List_of_hydroelectric...

    The 180MW Francis turbine-generator running at full speed was instantaneously stopped by a foreign body left in the penstock following maintenance.[7] The installation shifted about 2m within the base of the 180m high earth and rock fill gravity dam wall of the 3,906GL reservoir.

  9. Van de Graaff generator - Wikipedia

    en.wikipedia.org/wiki/Van_de_Graaff_generator

    Therefore, leakage from the terminal determines the maximum voltage attainable. In the Van de Graaff generator, the belt allows the transport of charge into the interior of a large hollow spherical electrode. This is the ideal shape to minimize leakage and corona discharge, so the Van de Graaff generator can produce the greatest voltage.
