Title:
PARALLEL MULTI-END DIRECT CURRENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/284216
Kind Code:
A1
Abstract:
A parallel multi-end direct current system. Direct current sides of transmitter-end bipolar converter stations and a receiver-end bipolar converter station are connected by means of positive electrode direct current submarine cables and negative electrode direct current submarine cables. Regarding neutral-line connections of the transmitter-end bipolar converter stations, only one neutral-line direct current submarine cable is used to connect the receiver-end bipolar converter station and the transmitter-end bipolar converter station closest to the receiver-end bipolar converter station, and the neutral line of said transmitter-end bipolar converter station is connected to the neutral lines of the other transmitter-end bipolar converter stations by means of other shorter neutral-line direct current cables. By means of the wiring mode, the length of the neutral-line submarine cables can be reduced, and the marine utilization space is reduced.
