Question
Why HVDC systems are considered more beneficial for underwater and underground power links?*HVDC cables are less complex to manufacture.HVDC transmission does not suffer from the capacitance issues that plague EHVAC systems.HVDC systems require alternating currents.There is no need for inverters in HVDC systems.
Solution
High Voltage Direct Current (HVDC) systems are considered more beneficial for underwater and underground power links for several reasons:
-
Less Complex to Manufacture: HVDC cables are less complex to manufacture compared to their AC counterparts. This makes them more cost-effective and efficient for long-distance transmission.
-
No Capacitance Issues: Unlike Extra High Voltage Alternating Current (EHVAC) systems, HVDC transmission does not suffer from capacitance issues. Capacitance can cause power loss over long distances, which is not a problem with HVDC systems.
-
No Need for Alternating Currents: HVDC systems do not require alternating currents. This means that they can transmit power more efficiently, without the need for the power to be converted back and forth between AC and DC.
-
No Need for Inverters: In HVDC systems, there is no need for inverters. Inverters are used in AC systems to convert the power from DC to AC, and they can be expensive and complex to maintain.
In conclusion, HVDC systems are more beneficial for underwater and underground power links due to their simplicity, efficiency, and cost-effectiveness.
