High voltage direct current

With the growing demand for higher voltages, AC became popular as it could be easily converted to higher voltages, with fairly less power loss. However, after the invention of thyristor valves by An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line. It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: High-voltage direct current. HVDC or high-voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power.

High voltage direct current

HVDC systems utilize power electronics technology to convert AC and DC voltage and are ideal for supporting existing systems or building new power highways.

AC is not efficient and needs power factor management for efficiency.

High-voltage direct current (HVDC) transmission systems are becoming more and more important in an energy landscape that is characterized by increasing digitalization, decarbonization, and distributed generation. However, over the last several decades, High-Voltage Direct Current (HVDC) has emerged as a viable complement to AC power transmission, with the ability to connect asynchronous AC grids and allow power transmission across long distances with minimal losses. A high-voltage, direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. Most HVDC links use voltages between 100 kV and 800 kV.
