    en.wikipedia.org/wiki/ALCO_DH643

    The ALCO C-643DH, also known as the Century 643DH, was a twin-engine diesel-hydraulic locomotive, the first diesel-hydraulic road switcher built in the United States. It had a C-C wheel arrangement and generated 4,300 horsepower (3,200 kW). Only three were built, all for Southern Pacific Railroad in 1964 (#9018–#9020).

    en.wikipedia.org/wiki/IBM_9020

    The IBM 9020 was an IBM System/360 computer adapted into a multiprocessor system for use by the U.S. FAA for Air Traffic Control. [1] Systems were installed in the FAA's 20 en route Air Route Traffic Control Centers (ARTCCs), beginning in the late 1960s. [2]: 6 The U.K. CAA also installed a system in its London centre. [3]

  4. North American power transmission grid - Wikipedia

    en.wikipedia.org/wiki/North_American_power...

    The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.

  5. Grid code - Wikipedia

    en.wikipedia.org/wiki/Grid_code

    A grid code is a technical specification which defines the parameters a facility connected to a public electric grid has to meet to ensure safe, secure and economic proper functioning of the electric system.

  6. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    The combined transmission and distribution network is part of electricity delivery, known as the power grid. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power ...

  7. 249th Engineer Battalion (United States) - Wikipedia

    en.wikipedia.org/wiki/249th_Engineer_Battalion...

    The 249th Engineer Battalion (United States) is a versatile power generation battalion assigned to the U.S. Army Corps of Engineers that provides commercial-level power to military units and federal relief organizations during full-spectrum operations.

  8. Texas Interconnection - Wikipedia

    en.wikipedia.org/wiki/Texas_Interconnection

    The Texas Interconnection is an alternating current (AC) power grid – a wide area synchronous grid – that covers most of the state of Texas. The grid is managed by the Electric Reliability Council of Texas (ERCOT). The Texas Interconnection is one of the three minor grids in the North American power transmission grid.

  9. Smart grid - Wikipedia

    en.wikipedia.org/wiki/Smart_grid

    The Kuramoto model is a well-studied system. The power grid has been described in this context as well. [61] [62] The goal is to keep the system in balance, or to maintain phase synchronization (also known as phase locking). Non-uniform oscillators also help to model different technologies, different types of power generators, patterns of ...
