METHOD AND SYSTEM FOR ARCHITECTURE, CONTROL, AND PROTECTION SYSTEMS OF MODULAR STACKED DIRECT CURRENT SUBSEA POWER SYSTEM

摘要

A high-voltage DC (HVDC) power system and a method of controlling and protecting the HVDC power system includes a plurality of sending-end (SE) modules coupled in electrical series and a plurality of receiving-end (RE) power converter modules electrically coupled to said plurality of SE modules, the RE modules coupled in a switchyard configuration, the switchyard configuration including a plurality of load branches coupled together in electrical series, each load branch including a branch bypass switch configured to bypass load current around an associated load branch, and a branch protection system.
