ARRANGEMENT FOR EXTERNAL BLACK START OF SUBSEA POWER SYSTEM

摘要

An arrangement for external black start of a subsea power system is described. The subsea power system comprising a subsea main power distribution switchboard fed from a topside power supply, at least one main power switchgear control module controlling the subsea main power distribution switchboard, at least one subsea auxiliary power distribution switchboard, and at least one subsea auxiliary power switchgear control module controlling said auxiliary power distribution switchboard. The subsea power system further includes at least one critical switchgear control module connected to an external power source, said critical switchgear control module being operable to control the main power switchgear and /or auxiliary power switchgear in order to perform a black start.
