用于中压直流电网大功率直流断路器的并联/串联标准化有源开关模块

Parallel/Series Connected Standardized Active Switching Modules for High Power DCCBs in MVDC Networks

语言:

中文摘要

固态直流断路器(DCCB)在MVdc网络中应用广泛,但受限于半导体器件的电压和电流等级。本文提出了一种模块化设计方法,通过并联和串联标准化有源开关模块,以解决中压直流电网中DCCB电压与功率等级多样化的挑战,实现固态断路器的灵活集成与扩展。

English Abstract

Solid-state dc circuit breakers (DCCBs) are increasingly employed across all power levels, including MVdc networks. Seamless integration of DCCBs into medium voltage direct current (MVdc) networks is challenging due to the diverse voltage and power levels. Furthermore, the limited current and voltage capability of semiconductor devices limits the full integration of solid-state DCCBs for MVdc appl...
