摘要

电力系统的电力电子化趋势使得宽频率测量需求愈发凸显，具有优良频率响应的全光纤电流互感器（fiber optical current transducer，FOCT）得到了越来越多的应用和关注。文中在介绍FOCT的基本原理和分析方波闭环调制方式信号处理过程的基础上，揭示了FOCT频率特性的主要影响因素，并提出区别于传统方波闭环调制的定频调制方法。通过固定调制解调频率，与光路长度解耦，保证了FOCT产品频率特性的一致性。试验结果表明，该方法可以消除光学电流互感器频率特性的差异性，为电力系统谐波电流测量与分析提供稳定可靠的数据来源。

Abstract

The trend toward electronization in power system has made wide-frequency measurement demands increasingly prominent

and all fiber optical current transducer(FOCT)with excellent frequencyresponse has therefore gained growing applications and attention. On the basis of introducing

the basic principle of FOCT and analyzing the signal processing process of square wave closed-loop modulation

in this paper

the main influencing factors of FOCT frequency characteristics are revealed

anda fixed frequency modulation method

which is different from traditional square wave closed-loop modulation

is proposed. By fixing the modulation and demodulation frequency and decoupling it from the optical path length

the consistency of the frequency characteristics of FOCT products is ensured.The test result shows that the method can eliminate the difference of frequency characteristics of the optical current transducer and provide stable and reliable data sources for harmonic current measurement and analysis of power systems.
