摘　　要：通过改变磁控限流器的直流偏置电流可以改变限流器输出电抗,与串联电容配合可在限流的基础上具备串联补偿功能。本文提出了一种磁控串联补偿限流器(MSCFCL),通过等效磁路等理论分析方法对其铁心与线圈的主要参数进行了详细设计;并提出了铁心开气隙结构来满足对输出电抗调节的需求。通过JMAG软件仿真分析了MSCFCL稳态下电抗输出与故障态下限流性能。仿真结果表明,以饱和电抗器为核心加入合理气隙结构的MSCFCL,可满足串联补偿的输出电抗平滑度要求,并且对限流性能有明显影响。By changing the DC bias current of the magnetron current limiter,the output reactance of the current limiter can be changed.In conjunction with the series capacitance,series compensation can be provided on the basis of the current limit.In this paper,a magnetically controlled series compensation fault current limiting(MSCFCL)is proposed.The main parameters of the core and the coil are designed in detail through theoretical analysis methods such as equivalent magnetic circuit.A core open air gap structure is proposed to meet the demand for output reactance regulation.The JMAG software simulates and analyzes the reactance output of the MSCFCL under steady-state conditions and the lower-limit performance of the fault state.The simulation results show that adding a reasonable air-gap structure of MSCFCL with a saturable reactor as the core can satisfy the output reactive smoothness requirements of the series compensation and at the same time have a significant impact on the current limiting performance.
