Introduction to Ultra High Voltage Power Transmission
Ultra High Voltage (UHV) power transmission refers to the use of extremely high voltage levels, typically above 800 kV for direct – current (DC) and 1000 kV for alternating – current (AC) systems, to transmit large amounts of electrical energy over long distances. UHV power transmission has several significant advantages. It can reduce power losses during long – distance transmission, improve the efficiency of power transfer, and enhance the stability and reliability of the power grid. With the continuous growth of global energy demand and the increasing distance between power generation sources and load centers, UHV power transmission has become an important solution for large – scale power delivery.
