Introduction to Ultra High Voltage Power Transmission
Ultra High Voltage (UHV) power transmission refers to the use of extra – high voltage levels (usually 1000 kV and above for AC and ±800 kV and above for DC) to transmit large amounts of electrical energy over long distances. UHV power transmission has several significant advantages. It can reduce power loss during long – distance transmission, improve the efficiency of power grid operation, and enhance the stability and reliability of the power supply. It is an important technology for optimizing the allocation of energy resources on a large scale, especially in a vast country like China, where it helps to transmit power from energy – rich regions to areas with high power demand.
