MODULAR STACKED SUBSEA POWER SYSTEM ARCHITECTURES

摘要

A sub-sea power delivery system (10) includes a plurality of modular power converter building blocks (12), (13) on each of the power source (20) side and the sub-sea load side (30) that are stacked and interconnected to meet site expansion requirements and electrical load topologies. The power delivery system comprises (10) a system DC transmission link/bus (14), wherein the system DC link (14) is configured to carry HVDC or MVDC power from an onshore utility or topside power source (20) to multiple sub-sea load modules (18). The stacked modular power converter topology on the sub-sea side of the sub-sea power delivery system (10) is symmetrical with the stacked modular power converter topology on the on-shore/top-side of the sub-sea power delivery system (10).
