MEDIUM VOLTAGE DC COLLECTION SYSTEM WITH POWER ELECTRONICS

摘要

A power generation system (10) includes at least one generator (12) that generates a medium voltage direct current that has a positive DC voltage output (50A) and a negative DC voltage output (52B). The system also provides a medium voltage DC (MVDC) cable system (66) with a positive pole cable (62) and a negative pole cable (64), wherein the positive pole cable is connected to the positive DC voltage output and the negative pole cable is connected to the negative DC voltage output. A substation (110) is connected to the MVDC cable system and includes at least one DC/DC step-up converter (114) to step-up the medium voltage direct current to a high voltage direct current (HVDC).
