A Self-adapting Fault Current Limiting Strategy for Flexible HVDC System Based on Source-network Current Limiting Contribution Coordination
故障限流是保障直流输电系统安全运行的关键技术,现有源侧和网侧限流方法通常独立配置且未与故障严重程度相匹配,难以兼顾限流能力与设备成本.针对上述问题,该文提出一种考虑故障严重程度的源网自适应限流策略,利用源侧模块化多电平换流器(modular multilevel converter,MMC)与网侧故障限流器(fault current limiter,FCL)的限流贡献度配合,实现主动匹配限流目标和故障条件的自适应限流.能够在保障限流能力的前提下…查看全部>>
Fault current limiting is the key technology to ensure the safe operation of HVDC system.The existing source-side and network-side current limiting methods are usually configured independently and do not match the severity of faults,so it is difficult to balance the current limiting capability and the cost of device.To solve the above problems,this paper proposes a fault limiting strategy based on source-network coordination considering the severity of fault…查看全部>>
