  2. Grid-tie inverter - Wikipedia

    en.wikipedia.org/wiki/Grid-tie_inverter

    Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...

  3. Grid-tied electrical system - Wikipedia

    en.wikipedia.org/wiki/Grid-tied_electrical_system

    A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall ...

  4. Solar inverter - Wikipedia

    en.wikipedia.org/wiki/Solar_inverter

    The key role of the grid-interactive or synchronous inverters or simply the grid-tie inverter (GTI) is to synchronize the phase, voltage, and frequency of the power line with that of the grid. [8] Solar grid-tie inverters are designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that ...

  5. Inverter-based resource - Wikipedia

    en.wikipedia.org/wiki/Inverter-based_resource

    An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]

  6. Interconnector - Wikipedia

    en.wikipedia.org/wiki/Interconnector

    An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .

  7. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]

  8. Fault current limiter - Wikipedia

    en.wikipedia.org/wiki/Fault_current_limiter

    A fault current limiter (FCL), also known as fault current controller (FCC), [1] is a device which limits the prospective fault current when a fault occurs (e.g. in a power transmission network) without complete disconnection. The term includes superconducting, solid-state and inductive devices. [2]

  9. Pacific DC Intertie - Wikipedia

    en.wikipedia.org/wiki/Pacific_DC_Intertie

    The Pacific Intertie consists of: [4] The Celilo Converter Station which converts three phase 60 Hz AC at 230 to 500 kV to ±500 kV DC (1000 kV pole-to-pole) at . The grounding system at Celilo consists of 1,067 cast iron anodes buried in a two-foot (60 cm) trench of petroleum coke, which behaves as an electrode, arranged in a ring of 2.0 miles (3,255 m) circumference at Rice Flats (near Rice ...
