An electric power transmission system that isolates a local AC transmission network from a surrounding AC system includes a local AC load center having a plurality of local AC loads, and a distribution feeder serving the plurality of local AC loads and at least one distant electric power generating station or other power source for supplying AC power to the local AC load center. A complete or partial DC transmission ring is interposed between the local AC load center and the distant electric power generating station for isolating the AC power received from the distant electric power generating station from the local AC load center by converting the AC power to DC power. The DC power is re- converted into AC power based on load requirements and the distribution feeder supplies the AC power while all local AC loads are Isolated from the distant electric power generating station.
Le présent extrait concerne un système de transmission d'énergie électrique qui isole un réseau de transmission c.a. local depuis un système c.a. environnant, qui inclut un centre de charge c.a. local ayant plusieurs charges c.a. locales, et un câble de distribution desservant ces charges c.a. locales et au moins une centrale électrique distante ou autre source d'alimentation en courant alternatif du centre de charge c.a. local. Un anneau de transmission de c.a., complet ou partiel, est intercalé entre le centre de charge c.a. local et la centrale électrique distante pour isoler l'alimentation en c.a., reçue de la centrale électrique distante, du centre de charge c.a. local, en convertissant l'alimentation c.a. en alimentation c.c. L'alimentation c.c. est reconvertie en alimentation c.a. sur la base des exigences de charge, et le câble d'alimentation apporte l'alimentation c.a. pendant que toutes les charges c.a. locales sont isolées de la centrale électrique distante.
