Title:
HVDC POWER TRANSMISSION WITH CABLE FAULT RIDE-THROUGH CAPABILITY
Document Type and Number:
WIPO Patent Application WO/2012/146621
Kind Code:
A3
Abstract:
A high voltage direct current (HVDC) power transmission system includes a cable fault ride-through system. The cable fault ride- through system is configured to ensure the HVDC power transmission system remains operational via an earth path between the power source end and the load end during a transmission cable fault, even in the absence of a neutral bus and/or dc circuit breakers. The return current is transferred via earth electrodes to earth, like e.g. the surrounding water in a sub-sea environment.
