The solution does away with the need for separate substations bundling alternating current (AC) electricity and converter rigs that transform that power into direct current (DC) electricity that is subsequently sent to land via sub-sea high-voltage direct current (HVDC) lines.
Instead, Siemens is developing smaller units that combine the bundling of power from the turbines with its conversion into DC. Depending on the size of a wind park, several of these platforms in a modular approach can be connected sequentially via a DC cable, which could then flow power to shore.
