基于Rogowski线圈用数字积分器的设计

Design of Digital Integrator Based on Rogowski Coil

设计了一个能用于Rogowski线圈的数字积分器,能克服直流偏移对传统积分器的影响,解决了积分器的饱和问题,并且利用DSP Builder工具完成了对算法的编程。该方法在现场可编程门阵列芯片具体实现中加入直流分量,连续运行72 h不发生饱和现象。

A digital integrator for Rogowski coil was designed,which could overcome the impact of DC offset to traditional integrator and solve the problem of integrator saturation,and DSP Builder tool was used to complete the programming of algorithms.The method proposed had implemented on field programmable gate array（FPGA） chip and saturation didn＇t occur when joining DC offset to run 72 hours continuously.
