Enhancing stability of Photovoltaic-Energy storage-Direct current-Flexibility power system with a novel integrated Superconducting Magnetic Energy Storage-Fault Current Limiter (SMES-FCL)

Journal of Physics: Conference Series
Abstract In order to enhance the stability and reliability of the Photovoltaic-Energy storage-Direct-Flexible (PEDF) system, a novel line-compensation superconducting magnetic energy storage-fault current limiter (SMES-FCL) was designed to address voltage fluctuations and fault current limiting issues.

Influence of Shunt Branch on the Current Limiting and Recovery Performance of Variable Resistance SFCL

IEEE Access
With the continuous development of power grid, the high short-circuit threatens the stability of the power system. The short-circuit exceeds the disconnection capacity of the circuit breaker and has a negative impact on the integrity and stability of the

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。
