为动态调整配电网电压，并在故障时降低短路电流水平，分析了基于铁心控制的串联补偿限流装置。该装置由固定电容、旁路断路器、氧化锌限压电阻、直流励磁铁心磁控电抗器构成。正常运行时，装置工作于串联补偿状态；故障时，迅速切换到限流模式运行，有效限制短路电流。该装置由传统晶闸管控制的串补设备改进而来，具有输出谐波小、控制简单的特性。通过Jmag和Matlab/Simulink软件对系统进行了仿真分析，仿真结果验证了该装置设计方案的可行性。

To adjust voltage of distribution network dynamically and limit short-circuit current level during the fault, a new core controlled series compensating and fault current limiting (CCSC-FCL) device, which is composed of fixed capacity, by-pass circuit breaker, ZnO metal oxide varistor and DC exciting core controlled reactor, is proposed. During normal operation, the CCSC-FCL device works in the state of series compensation and during the fault it can be rapidly switched to the fault current limiting mode to effectively limit short-circuit current. The proposed CCSC-FCL device is improved from traditional thyristor-controlled series compensation (TCSC), which possesses the features of low harmonic components in its output and easy to control. The simulation analysis on the proposed CCSC-FCL device is carried out by Jmag and Matlab/Simulink software, and the feasibility of the proposed CCSC-FCL scheme is validated by simulation results.
