Coordinated Source-Grid fault current limiting strategy in HVDC grids based on fault severity and quantitative limitation demand

International Journal of Electrical Power & Energy Systems
Reliable fault current limitation is critical in high-voltage direct current (HVDC) grids due to the fast dynamics and low fault tolerance of power electronic equipment, as well as the high cost of DC circuit breakers (DCCBs). To address these challenges,

非线性变压器理论在高压直流故障电流限制器中的应用研究

Gaoya dianqi, 2019
高压直流故障电流限制器（fault current limiter,FCL）是先进超导托卡马克装置系统中用于抑制短路电流,保护中性束注入系统的一种类变压器装置。文中从变压器铁心叠片的涡流损耗特性出发,采用分段线性插值的方法对FCL非线性磁滞回线模型进行优化,推导出非线性激磁电阻与电感的并联模型。通过仿真及实验的对比分析,结果表明优化磁滞回线模型仿真波形与试验结果吻合度高,短路电流抑制效果良好。

New resonance type Fault Current Limiter

, 2010
This paper proposes a new parallel LC resonance type Fault Current Limiter (FCL). This structure has low cast because of using dry capacitor and non-superconducting inductor and fast operation.
