Offshore Wind Export Cable: HVAC vs HVDC Transmission

Interactive 3D simulator of an offshore wind farm's submarine export cable: watch how HVAC charging current eats into cable capacity over distance while HVDC pays a fixed converter-station tax, and find the real crossover distance engineers use to choose between them.

This simulator models the submarine export cable that carries an offshore wind farm's power to shore — the piece of infrastructure that, more than any turbine, decides whether a project is built as HVAC or HVDC. Adjust the wind farm's output, the distance to shore and the conductor's cross-section, and watch a real 3D scene of turbines, seabed cable and onshore substation update as animated particles carry real and reactive current down the line. Live readouts track delivered power, transmission loss, cable utilization and — depending on the chosen technology — either the AC charging current or the fixed HVDC converter-station loss, so you can find the crossover distance where HVDC starts winning for yourself.

⚙ Under the hood

Model a submarine export cable carrying an offshore wind farm's power to shore, and see why HVAC's charging current caps capacity over distance while HVDC pays a fixed converter-station loss instead.
