Modular Combination Type Dynamic Braking Resistor Based on Thyristors and Its Coordinated Control Strategy
针对模块化多电平换流器(modular multilevel converter,MMC)高压直流输电技术(high voltage direct current,HVDC)受端交流系统故障引起的直流过电压问题,文中提出一种基于晶闸管的模块化组合式直流泄能装置拓扑及协调控制方法.该直流泄能拓扑包括模块化分布式泄能部分、限流电抗器和集中式泄能电阻3部分,对子模块工作模式进行设计,提出可避免直流泄能装置反复投切的弹性调节泄能的协调控制策略,推导直流泄…查看全部>>
Aiming at the DC side over-voltage problem caused by the AC side fault at the receiving end of modular multilevel converter based high voltage direct current transmission(MMC-HVDC),this paper proposes a modular combination type dynamic braking resistor topology based on thyristor and its coordinated control method.The topology includes modular release energy release part,current limiting reactor and centralized energy release resistor.The sub-module working …查看全部>>
