Patent number: 11005261Abstract: A control method allows the control of an installation for transmitting electricity comprising a DC transmission network including a group of electricity transmission lines that are linked to one another. The method allows the opening of at least one N-1 safety system, for each safety system being opened, the contribution to the flow of current through the group of transmission lines, originating from the converter station associated with the safety system that is opened, is removed. Furthermore, the method also allows a search for the short-circuit fault in order to identify the faulty transmission line, and an operation, implemented after identification of the faulty transmission line by the search step, of isolating the faulty transmission line by opening the line circuit breakers of the faulty transmission line.Type: GrantFiled: August 30, 2017Date of Patent: May 11, 2021Assignees: Supergrid Institute, Universite Grenoble AlpesInventors: Dieynaba Loume, Alberto Bertinato, Bertrand Raison
