  3. Slide 3: A short history of AC and DC transmission

    A short history of AC and DC transmission In the AC corner: In the DC corner: Circa 1885: Two technologies George Westinghouse Thomas Edison 1920s: AC grids became common - vs - 1960s: Birth of power electronics Today: HVDC is the key technology for interconnecting regions i i Idc and countries. Iac

  4. Slide 4: Uses of HVDC today

    Uses of HVDC today 1 Back-to-back interconnections ƒ Connects ‘mismatched’ AC networks 1 ƒ Frequency conversion 50-60 Hz 2 Point-to-point connections ƒ Connects power generation to distant load-centres ƒ Develops energy highways to transfer large amounts of power over long distances 4 ALSTOM © 2010

  5. Slide 5: HVDC vs HVAC

    HVDC vs HVAC Station Cost Break Even DC Distance DC Convertor Stations AC AC Stations Transmission Distance HVDC = ‘more power per tower’ in Break even distance: less space and with less infrastructure ƒ Overhead lines = 700 km ƒ Submarine cable = 40 km 5 ALSTOM © 2010 Confidential

  6. Slide 6: Types of HVDC technologies

    Types of HVDC technologies ƒ Line Commutated Back-to-back interconnections Converters (LCC) – HVDC up to 500 kV ƒ LCC – UHVDC Point-to-point long distance transmission (energy highways) up to 800 kV ƒ Voltage Source Converters Connecting renewable energies (VSC) – HVDC ƒ For bi-directional grids ƒ F

  7. Slide 7: The difference between LCC and VSC
