摘　　要：分析测量不同脉冲宽度电流的 Rogowski测量线圈的数学模型、时域和频域特性以及最佳阻尼参数配合和优选问题并比较了基于 MATL AB环境下 SIMU L INK工具所做的仿真结果和现场实验采集到的脉冲电流波形。提出了复合积分器电路模型 ,可用于优选 Rogowski线圈的电气和结构参数 ,有效抑制积分漂移 。The paper presents in detail the analysis of models, time-domain specifications and frequency characteristics of Rogowski coils used to measure different durations of pulsed current with large amplitude. At the same time the choice method of optimal parameters of damp resistance has been introduced and emphasized. The presented method was simulated by means of an advanced simulation tool: SIMULINK tools based on MATLAB environment. Simulation results, experimental results and performance of Rogowski coils are described respectively. For inhibiting effectively the integrating drift, the compound integrator, a new type of integrator, has been introduced in this paper. The simulation and experiment results indicate that effectiveness of the algorithm of the control system can satisfy the practical application. This kind of research method is of great benefit to choose the parameters of the coils and is convenient for designing dependable and accurate Rogowski coils for measuring pulsed current.
