HVDC

You already know from your engineering that higher voltages results to less operational losses for the same amount of power delivered. The bulk capacity of 3000MW has a great influence on the investment costs obviously, that determines the voltage level and the required number of parallel circuit. The need for higher voltage DC levels has become more feasible for bulk power projects (such as this one) especially when the transmission line is more than 1000 km long. So on the economics, invest ...

HVDC means High Voltage Direct Current and it enables controllable exchange of Active Electrical Power between two stations since the two stations in case of their being connected over HVDC link. As any electrical engineer would know, flow of power between two ends of a transmission line would comprise two components one of which would be Active Power measured in Watts (W) or kilo Watts (kW) or Mega Watts (MW) etc, and the other component wo ...

HVDC has been in existence for a long time but has become so popular these days with weighing advantages for the traditional HVAC transmission technology. HVDC system uses direct current for the bulk transmission. There are different configuration, types and topologies to include HVDC back to back, classical HVDC, etc.

The advantages lies in the fact HVDC links are able to connect to two asynchronous network, a typical example is a 60Hz and 50Hz ...

Lot of literature can be found in French since France and Quebec are the countries where the HVDC transmission is very developed and already mature technology.
Why it is used? The answer is to avoid corona effect which is a source of energy losses, which are between 5-8% of the nominal installed power (huge if you compare with the power of a single transmission line). For this reason almost all of the long distance transmission lines from Siberia to European part of Russia are HVDC whic ...
