WebAccording to the type of HVDC system, the number of conductors is selected. It is used to transmit the HVDC power from the sending end to the receiving end. In the DC system, there is no skin effect due to the absence of frequency. And compared to the HVAC system, the size of the conductor is small for the same power. These networks use components such as power lines, cables, circuit breakers, switches and transformers. The transmission network is usually administered on a regional basis by an entity such as a regional transmission organization or transmission system operator. Transmission efficiency is improved at higher voltage and lower current. The r…
