摘要
随着柔性直流输电技术的快速发展,直流配电网受到了更多的重视。直流变压器实现了不同电压等级直流配电网之间的互联,是直流配电网中的关键设备,同时也是当前制约直流配电网推广的主要因素之一。对直流变压器国内外的研究现状进行总结,在分析直流变压器原理的基础上,总结了常见的直流变压器的拓扑结构和应用场景;分析了直流变压器的主要控制策略、关键技术问题以及目前的主要研究方向,并对直流变压器的研究方向进行展望。
With the rapid development of flexible HVDC technology,more attention has been paid to DC distribution network.DC transformer realizes the interconnection between DC distribution networks with different voltage levels,which is the key equipment in DC distribution network and is also one of the main factors restricting the popularization of DC distribution network.This paper summarizes the research status of DC transformer at home and abroad,and is based on the analysis of the principle of DC transformer to sum up the topological structure and application scenarios of common DC transformers.And then,the paper analyzes the main control strategies,key technical problems and current research directions of DC transformers,and also looks into the future of the research directions of DC transformers.
