摘要
本文主要介绍HVDC工程中电网换相换流器(LCC)和模块化多电平换流(MMC),前者采用半控器件晶闸管组成换流器,而后通过电网换相的方式实现换流;后者则采用全控器件组成换流器,通过控制器件的通断实现换流。
Line Commutated Converter (LCC) and Modular Multilevel Converter (MMC) were mainly introduced in this paper.The former uses a half-controlled device thyristor constitutes an inverter,and then commutates through the grid commutation method.The inverter uses a full control device,and the commutation is realized by controlling the on and off of the device.
