| 摘要: |
| 基于饱和铁芯型故障限流器的结构，提出控制直流偏置电流改变限流器输出电抗，从而当故障限流器与电容串联时，可以调节电容补偿系数。设计了限流器直流控制系统，利用氧化锌电阻的非线性特性和双滞环比较控制技术对直流偏置电流进行快速控制。对研制的限流器试验样机进行试验，试验结果表明，应用所提方法及直流控制系统后，串联补偿型故障限流器在系统正常运行时可以实现输出电抗的调节，在系统发生故障时可有效限制短路电流，并在重合闸之前恢复低阻抗状态。 |

| Abstract: |
| Based on the structure of saturated core FCL（Fault Current Limiter），it is proposed to adjust its output reactance by controlling its DC bias current to modify the compensation coefficient of the capacitors，which are connecting with the FCL in series. A system adopting the nonlinear characteristics of ZnO resistor and dual hysteresis control technology is designed for the rapid control of DC bias current. A prototype of FCL is developed and the test results show that，the series-compensation-type FCL under the control of proposed system adjusts its output reactance during normal operation while limits the short circuit current during system fault，and it recovers the low-impedance state before the reclosing. |
