配网柔性直流背靠背互联接线方案

Connection Scheme of Flexible Direct Current Back-to-Back Interconnection in Distribution Networks

随着新型电力系统的发展,配网的运行特点和结构也发生了巨大变化。柔性直流背靠背互联可有效解决配网面临的一些问题。研究柔性直流背靠背互联系统接线,从系统接线、联接变配置方式、换流器接线等方面进行对比分析,提出了一种可靠性高、技术经济合理的接线方案。

With the development of power systems,the operating characteristics and structure of distribution networks have also undergone great changes.Flexible direct current back-to-back interconnection can effectively solve some of the problems faced by distribution networks.In this paper,connection scheme of flexible direct current back-to-back interconnection system is studied.And a high reliability,technically and economically reasonable connection scheme is given by comparing and analyzing the system connection,connection of converter transformer and the topology of converters.
