| 摘要: |
| 对不失超型SFCL限流时的线路电路变化曲线进行了理论分析和仿真计算，研究了其对节点测量阻抗和线路电流谐波特性的影响，并就动作电流对其特性的影响进行了详细分析。仿真计算结果表明，不失超型SFCL的阻抗虽然随着线路电流周期性变化，但对线路电流谐波特性的影响不大，完全可用于电力系统，它对节点测量阻抗的影响与其动作电流有直接关系。 |

| Abstract: |
| The theoretic analysis and simulative calculation of the line current curve limited by SFCL without quench are presented.The influence of SFCL without quench on measurement impedance of transmission line and harmonic characteristic of line current is analyzed.The impact of working current on its characteristic is also studied.Simulative calculation results show that,the impedance of SFCL without quench varies periodically with line current,which has little effect on harmonic characteristic of line current,and the impact on measurement impedance of transmission line is directly related to the working current of SFCL without quench. |
