Abstract

本申请涉及用于电压源变换器(VSC)的故障 保护的方法和设备。设备( 500 )具有与引导器开 关(104)串联的链节电路(103)。所述链节电路包 括多个单元(106),每个单元包括储能元件(108) 和与反并联二极管连接的多个单元开关元件 ( 109 ),所述单元开关元件被配置成使得所述储 能元件能够选择性串联连接在所述单元的端子 之间或者被旁路。每个单元开关元件具有关联的 单元开关元件控制器( 501 ,502 )。所述引导器开 关包括多个引导器开关单元( 202 ),每个引导器 开关单元具有引导器开关元件(110)和引导器开 关单元控制器( 503 )。每个单元开关元件控制器 被配置成监测故障电流,并且在检测到故障电流 的情况下,关断其关联的单元开关元件,并将故 障事件报告给故障控制器( 504 )。每个引导器开 关单元控制器还被配置成监测故障电流,并且在 检测到故障电流的情况下,将故障事件报告给所 述故障控制器,但所述引导器开关单元控制被配 置成保持其关联的引导器开关元件接通。所述故 障控制器(504)被配置成监测故障事件的任何报 告以确定是否出现故障,并且在出现故障的情况 下,命令所述多个单元的至少一些的所有单元开 关元件关断。
