HVDC换流站电流特性分析及测量装置的选取
基于电网换相换流器的高压直流(Line Commutated Converter Based High Voltage Direct Current,LCC-HVDC)输电系统在远距离大容量输电的应用场景下具有显著的优势[1-3]。为了实现“双碳”目标,需要将西部大量的清洁能源送到距离很远的东部负荷中心,而LCC-HVDC 适合于承担这样的输电任务,因此LCC-HVDC 系统在“西电东送...

VSC_HVDC输电系统模式切换控制策略
When faults occur in an AC transmission line connected with CSC-based HVDC station, commutation failure can happen leading to DC voltage collapse [16]. Distance relays are used to protect the AC transmission lines from such disturbances. Internal converter faults are related to device misfire / ...
