摘要

重点关注适用于多端柔性直流输电系统的直流潮流控制技术

在分析已有直流潮流控制技术基础上

文中提出了一种适用于多端柔性直流输电系统的线间直流潮流控制器

其具有结构简单、所需元器件少以及无需外部电源等优点。对一个包含该线间直流潮流控制器的三端环网式直流输电系统进行研究

分析了该控制器的工作原理及运行特性。在PSCAD／EMTDC中搭建了该系统的仿真模型

对其进行稳态、动态以及故障情况下的仿真验证。仿真结果表明

该线间直流潮流控制器在多种工况下都可以有效地实现直流潮流控制

并保持良好的稳定性。

Abstract

This paper focuses on the technology of direct current (DC) power flow control suitable for voltage source converter based multi-terminal high voltage DC (VSC-MTDC) systems. Based on an analysis of existing DC power flow controllers

a novel interline DC power flow controller (IDCPFC) is proposed for VSC-MTDC systems

which has the benefit of simpler circuit topology

fewer components and no external power supply needed. A three-terminal high voltage DC system including the IDCPFC is studied and its operation principle and characteristics are analyzed. Finally

steady state

dynamic state and fault condition simulations are performed with PSCAD/EMTDC to validate the feasibility of the proposed IDCPFC. The results show that the proposed IDCPFC can effectively realize DC power flow control. This work is supported by National Natural Science Foundation of China (No. 51307024)
