A Instantaneous Approach of Measuring Harmonic Current with Rogowski Coils at the dc-Side of HVDC
【摘要】 HVDCdc侧谐波电流的实时检测是实现ADF抑制谐波的重要环节 .介绍了Ro gowski线圈的原理 ,设计了相应的积分电路 .为获取有效电流信号 ,设计了Butterworth带通滤波器 ,最后给出了模拟仿真结果 .
【Abstract】 In order to suppress harmonic current on the dc line of HVDC with ADF,it is very importance that realizing harmonic current realtime measurement on dc_side of HVDC.This paper intruduces the theory of Rogowski coils,designs the integrator for Rogowski coils EMF and Butterworth bandpass filters for obtaining compensation current signals.At last ,the simulation result is presented in the paper.
