HVDC (High-Voltage Direct Current)

High-Voltage Direct Current (HVDC) is a method of transmitting electricity over long distances using direct current at high voltages. Unlike traditional alternating current (AC) systems, HVDC minimizes energy losses over long distances, making it more efficient for transmitting bulk power between distant locations. It involves converting AC to DC at the source, transmitting the power through specialized cables or lines, and then converting it back to AC for distribution. HVDC is particularly useful for connecting offshore wind farms, undersea cables, or跨国 power links, offering improved stability, reduced electromagnetic interference, and lower operational costs for long-distance energy transmission.
