摘要： A power transmission and distribution system suitable for subsea electrical loads includes a primary dc transmission cable connected to an onshore AC/DC converter module that connects the onshore end of the cable to an ac supply network. The subsea end of the cable is connected to a primary subsea power distribution unit and includes a DC/DC converter module having a modular topology with a series of interconnected DC/DC converter units. The DC/DC converter module is connected between the cable and a primary dc distribution network. Secondary dc transmission cables and associated circuit breakers connect the primary subsea power distribution unit to secondary subsea power distribution units that are located near the subsea loads. Each secondary subsea power distribution unit includes a DC/DC converter module having a modular topology with a series of interconnected DC/DC converter units. Respective secondary dc distribution networks supply power to one or more subsea loads.

摘要： A power collection and transmission system can be used with a plurality of energy devices such as off-shore wind turbines. The energy devices are grouped into two or more clusters. The system includes a dc collection network for each cluster. A primary DC/DC converter is located at each energy device and is connected to the dc collection network. First and second dc transmission lines are used to transmit any power generated by the energy devices to an on-shore converter station. A secondary DC/DC converter assembly is connected between the dc collection networks and the first and second dc transmission lines.
