Title (EN) POWER FLOW CONTROL IN A MESHED HVDC POWER TRANSMISSION NETWORK
(FR) CONTRÔLE DES FLUX D'ÉLECTRICITÉ DANS UN RÉSEAU CC MAILLÉ À HAUTE TENSION
Abstract:
(EN) A meshed HVDC power transmission network (10) comprises at least three HVDC converter stations (1, 2, 3) interconnected in a first closed path by at least three transmission lines (16, 18, 20). A first DC power flow control device (30) is series connected to a first (20) of the at least three transmission lines. That first DC power flow control device (30) takes its power from the first transmission line (20) and balances the DC current distribution in the first closed path.
(FR) Un réseau CC (10) maillé de lignes à haute tension comprend au moins trois postes de conversion (1, 2, 3) interconnectés par une première boucle comprenant au moins trois lignes (16, 18, 20) de transmission. Un premier dispositif (30) de commande de l'intensité en CC est monté en série sur une première (20) des lignes de transmission. Le dispositif (30) de commande est alimenté par la première ligne (20) de transmission et équilibre la distribution du courant CC dans la première boucle.
