摘要

中国北京的配电系统运营部门正在研究一种交流/直流拓扑结构，以扩大本地配电系统。其特点是在三个变电站之间安装多端直流互连(MTDI)，以实现一次变压器N-1停电时的不间断负荷转移和更好的负荷共享。提出了一种具有多端直流互联(MTDI)的交直流混合配电网可靠性评估方法。本文主要包括MTDI的可靠性模型和供电恢复方案两大部分。案例研究是通过现实生活中的分销网络进行的。结果表明，采用MDCI接头可以提高配电网的可靠性，降低变压器容量。

Reliability assessment of AC distribution network with multi-terminal DC interconnection

The distribution system operation in Beijing, China, is investigating on an AC/DC topology for expanding a local distribution system. The feature is to install multi-terminal DC interconnections (MTDI) among three substations, in order to achieve un-interrupted load transfer as well as better loading sharing during primary transformer N-1 outages. This paper presents a reliability assessment of hybrid AC/DC distribution network with the multi-terminal DC interconnection (MTDI). This paper consists of two major parts, which are a reliability model of the MTDI and a power supply restoration scheme. Case studies are performed through a real-life distribution network. The results suggest that reliability of the distribution network can be improved and the capacity of the transformer can be reduced with the joint of MDCI.
