Abstract:
(EN) In the field of high voltage direct current (HVDC) power transmission there is provided a power converter assembly (10) comprising a line-commutated power converter (12) that is configured to transfer power from a DC network (14) to a corresponding receiving AC network (16). The power converter assembly (10) also includes a control unit which is operatively associated with the line-commutated power converter (12) and is programmed, in response to the receiving AC network (16) exhibiting a reduced AC voltage (Va, Vb, Vc), to cause a reduction in the operating DC voltage (VDC) of the line-commutated power converter (12) by the DC network (14).
(FR) La présente invention se rapporte au domaine de la transmission d'énergie en courant continu haute tension (HVDC) et concerne un ensemble convertisseur de puissance (10) qui comprend un convertisseur de puissance à commutation de ligne (12) configuré de façon à transférer l'énergie d'un réseau CC (14) vers un réseau CA de réception (16) correspondant. L'ensemble convertisseur de puissance (10) comprend également une unité de commande associée de manière fonctionnelle au convertisseur de puissance à commutation de ligne (12) et programmée de façon à provoquer, en réponse au réseau CA de réception (16) présentant une tension alternative réduite (Va, Vb, Vc), une réduction de la tension continue de fonctionnement (VDC) du convertisseur de puissance à commutation de ligne (12) par le réseau CC (14).
