Title (EN) TOPOLOGY FOR LIGHTWEIGHT DC ELECTRICAL TRANSMISSION SYSTEM
(FR) TOPOLOGIE POUR SYSTÈME DE TRANSMISSION DE COURANT ÉLECTRIQUE CONTINU LÉGER
(ZH) 一种轻型直流输电系统拓扑
Abstract:
(EN) Disclosed is a lightweight DC electrical transmission system topology consisting of a rectifier/converter station, an inverter/converter station and a direct current power transmission cable. The rectifier converter station comprises a phase shifting transformer and several direct current transmission output cascaded power units (U1P, U12P, U1N, U12N). The inverter converter station comprises power units (U1P, U12P, U1N, U12N), an LC filter circuit and a transformer. The direct current input-side power units (U1P, U12P, U1N, U12N) of the inverter converter station are cascaded and are connected to the direct current power transmission cable. Each power unit (U1P, U12P, U1N, U12N) of the inverter/converter station bears an equal part of direct current voltage and uses pulse width modulation (PWM) to convert direct current voltage into a low-voltage alternating-current output. The low voltage alternating current passes through the LC filter circuit and enters the secondary side of the transformer. The transformer outputs AC according to user requirements by means of different inverter/converter stations. The lightweight DC system topology features low costs, flexible allocation of DC voltage levels, and small harmonics.
(FR) L'invention concerne une topologie de système de transmission de courant électrique continu léger comprenant un poste redresseur/convertisseur, un poste onduleur/convertisseur et un câble de transmission de courant électrique continu. Le poste redresseur/convertisseur comprend un transformateur déphaseur et plusieurs blocs d'alimentation en cascade côté sortie (U1P, U12P, U1N, U12N) pour la transmission de courant continu. Le poste onduleur/convertisseur comprend des blocs d'alimentation (U1P, U12P, U1N, U12N), un circuit de filtrage LC et un transformateur. Les blocs d'alimentation en courant continu côté entrée (U1P, U12P, U1N, U12N) du poste onduleur/convertisseur sont montés en cascade et connectés au câble de transmission de courant électrique continu. Chaque bloc d'alimentation (U1P, U12P, U1N, U12N) du poste onduleur/convertisseur supporte une partie égale de la tension du courant continu et utilise une modulation d'impulsions en largeur (PWM) pour convertir la tension du courant continu en un signal de sortie de courant alternatif basse tension. Le courant alternatif basse tension passe à travers le circuit de filtrage LC et pénètre dans le côté secondaire du transformateur. Le transformateur fournit un courant alternatif selon les exigences de l'utilisateur au moyen de différents postes conduleurs/convertisseurs. Cette topologie de système c.c. léger est peu onéreuse, permet l'affectation souple de niveaux de tension c.c. et présente de faibles harmoniques.
