摘要

在多端柔性直流电网中

直流故障快速隔离和清除能力是系统可靠安全运行的保障。直流故障清除能力是制约基于半桥模块MMC发展的关键问题。文中提出了一种新型二极管箝位双子模块拓扑结构

在两个单子模块串联的基础上

增加了一个IGBT和一个二极管

利用子模块电容电压迫使导通的二极管反向截止

从而有效抑制MMC的不控整流效应

快速切断故障电流通路

具备直流故障自消除能力

Abstract

In the multi terminal flexible DC power grid

the rapid isolation and clearance of DC fault is the guarantee of the reliable and safe operation of the system.The scavenging capability of DC fault is the key problem that restricts the development of half bridge module MMC.This paper presents a new type of diode clamp double module topology

which adds a IGBT and a diode based on two series list module

and can force diode reverse cut-off.The new double module topology can effectively inhibit MMC rectifier effect and quickly cut off the fault current path with DC fault self-clearance capability

which has good economic and application value.
