The Historical Background of AC and DC SystemsLimitations of Three-Phase AC Transmission SystemsHVDC System ConfigurationHVDC Transmission SystemsThe Economic Aspect of HVDC Transmission SystemsThe first electrical power system was built and tested at the end of the 19th century. In the beginning, DC power systems were primarily used. The DC power transmission system had several limitations. DC voltage could not be transformed, meaning that energy could not be transmitted long-distance without high voltage drop values and power losses. Thomas Alva Edison and his team developed the DC generator, circuit breaker equipm…See more on allaboutcircuits.comResearch and application of UHV power transmission in ... 26, 2018Abstract: The power demand increases rapidly in China; however, the areas of huge power demands are of long distance from most areas of abundant energy resource in the country. Therefore, China put in great effort to develop ultrahigh voltage (UHV) power transmission systems to optimise its energy allocation.
