摘要

在含有网孔的多端直流输电系统或直流电网中

仅靠控制换流站难以实现对特定线路的潮流进行控制

因此需要引入直流潮流控制器来改善潮流分布。首先对现有的4类直流潮流控制器进行了原理介绍和优缺点分析

然后提出了一种新型线间直流潮流控制器。新拓扑具有以下优点:需要的开关器件和驱动更少;拓扑结构更简单;控制更简单。最后

在PLECS中搭建了一个三端直流输电系统

通过仿真验证了新拓扑的有效性。

Abstract

In a meshed multiterminal high voltage direct current (HVDC) system or a DC grid

it is difficult to control the power flow of a particular line by controlling the converter station. Therefore

it is necessary to use DC power flow controllers to improve the distribution of power flow. Firstly

the four types of existing DC power flow controllers are introduced and their advantages and disadvantages are analyzed. Then

a novel interline DC power flow controller is proposed. The new topology has the following advantages: fewer switching devices and drivers are required

the new topology has a simpler structure

and the control is simpler. Finally

a three-terminal HVDC system is built in PLECS

and the feasibility of the new topology is validated.
