摘　　要：介绍了一种基于Rogowski线圈的新型光电式电流互感器的基本结构和工作原理。利用传递函数方法和在Simulink环境下搭建电路模型的方法进行仿真,分析了该电流互感器在系统正常运行和故障状态下的传变特性。仿真结果表明,光电式电流互感器对于一次信号的波形具有良好的跟随作用,能很好地反映原方信号的各种频率分量的变化情况,通频带宽,暂态特性好。The basic structure and working principle of an optical current transducer based on Rogowski coils are introduced. Simulation is carried out using transfer function method with established circuit model under Simulink environment. Its transduction characteristics are analyzed under normal and faulty conditions of electric power system. Simulation results show that,it follows the waveform of primary signal and reflects the frequency component change of original signal,with wider bandwidth and better transient performance.
