Title:
MODULAR MULTI-LEVEL CONVERTER, CONVERTER VALVE SYSTEM AND SUB-MODULE NETWORKING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/077657
Kind Code:
A1
Abstract:
A modular multi-level converter, a converter valve system and a sub-module networking method. Communication optical fibers between sub-modules in a group and valve controllers are simplified, by means of optical switches, from the original multi-receiving multi-transmitting mode to a one-receiving one-transmitting mode, such that the control and monitoring of the sub-modules can be completed using a relatively small number of optical fibers between converter valve controllers and the sub-modules, which can save on costs and reduce the difficulty in laying on the basis of ensuring control synchronization. By means of arranging the optical switches, it is also possible to bypass a faulty sub-module in a timely manner, thereby avoiding the impact on information transmission during uplink or downlink communication. Sub-modules directly forward an instruction when receiving the instruction, thereby ensuring instruction reception synchronization. The mode of uploading information of the sub-modules themselves involves time-sharing delivery in the same direction, such that serial delivery without congestion can be realized.
