摘要： 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.
摘要翻译：将本地交流传输网与周围的交流系统隔离的电力传输系统包括具有多个本地交流负载的本地交流负载中心，以及服务于多个本地交流负载的分配馈线和至少一个远距离的发电站或其他电源为本地交流负载中心提供交流电源。在本地交流负载中心和远距离发电站之间插入一个完整的或部分的直流传输环，用于通过将交流电转换成直流电而将从远端发电站接收的交流电与本地交流负载中心隔离。直流电源根据负载要求重新转换为交流电源，分配馈线提供交流电源，而所有局部交流负载与远距离发电站隔离。
