Comparison Between HVDC and HVAC Transmission System
Aug 18, 2021 · An HVDC system of power transmission can be effectively used in a power system. Let us see the differences between high voltage direct current (HVDC) and high voltage alternating current (HVAC) transmission systems.
HVDC transmission systems use converters to change AC to DC (rectifier) and converting DC back to AC (inverter) (DTU and Cutululis). For this type of conversions, there are two main technologies. These technologies are the line commutated converter (LCC) and the voltage source converter (VSC).
Advantages of HVDC over HVAC Power Transmission
Main Advantages of HVDC over HVAC Transmission. The HVDC has a lower cost of transmission than HVAC above the Break-even distance. The HVDC transmission lines experience lower power losses as opposed to HVAC. There are no radiation & induction losses in HVDC. There are no dielectric losses in HVDC which increases the lifetime of the conductor.
