Abstract
(EN)
In general terms, the present invention relates to an electrical power transmission system using superconductors which is compatible with conventional transmission systems. In a first aspect, the present invention relates to a method for installing in an electrical power transmission system a connection using a coaxial superconducting cable, comprising the following steps: determining the reactance of a conventional cable suitable for the said connection; installing the coaxial superconducting cable; increasing the reactance of the coaxial superconducting cable, in such a way that the reactance of the superconducting cable is substantially equal to the reactance of the conventional cable. In particular, the step of increasing the reactance of the coaxial superconducting cable comprises the step of connecting in series with the coaxial superconducting cable an inductive element, preferably made from a superconducting material.

L'invention porte d'une manière générale sur un système de transmission de puissance électrique à supraconducteurs compatible avec les systèmes de transmission usuels; elle porte tout d'abord sur un procédé d'installation dans un système de transmission de puissance électrique d'un raccordement au moyen d'un câble supraconducteur en suivant les étapes suivantes: calcul de la réactance d'un câble usuel adapté à ce raccordement; mise en place du câble supraconducteur coaxial; augmentation de la réactance du câble supraconducteur coaxial jusqu'à ce qu'elle soit sensiblement égale à celle du câble usuel, cette dernière étape consistant en particulier à monter en série avec le câble supraconducteur coaxial un élément inducteur fait de préférence d'un matériau supraconducteur.
