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。

Calculation of a three phase fault in a network with a power electronic based fault current limiter (FCL)

2005 European Conference on Power Electronics and Applications, 2005
The model of a fault current limiter (FCL) based on a six-pulse thyristor rectifier with a freewheeling diode is described in this paper. The FCL is connected to a transformer's neutral terminal. Furthermore the state space description and the calculation method are presented.
