You will be able to understand why High Voltage Direct Current (HVDC) is used in power grid applications, how AC power is converted to DC power, and vice versa. You will be able to recognize the advantages and limitations associated with HVDC and identify the two types of converter substations and their main components.

• Definition and role of HVDC
• What is AC Current? DC Current? How does the AC/DC conversion work?
• Converter substations: point-to-point vs. back-to-back
• Point-to-point substations: overhead & cable applications including submarine cable HVDC lines
• Back-to-back substations with synchronous networks
• Converter substation components: converter transformer, converter, thyristor valve hall, smoothing reactor, AC and DC filters
• Next generation converters (VSC)
• HVDC history
• HVDC advantages & limitations
• Break-Even Point
• HVDC factors to consider
