随着智能电网建设的不断深入，全光纤电流互感器日益成为研究重点，其稳定性问题也逐渐受到人们关注。通过研究全光纤电流互感器中的光源稳定性问题，针对影响其稳定性的温度和驱动电流这2个主要因素设计了不同的解决方案。在温度控制方面，提出2种温控电路设计方案，最后根据实际需求采用数字式温控电路。在驱动电流控制方面，基于传统控制方案，设计了一种基于光源光功率调节驱动电流的方案，并对两者进行了实验论证。实验结果表明新的方案提高了互感器光源的可靠性和稳定性。

With the deepening development of the smart electric grid construction,fiber?optical current transducer(FOCT) has become the research focus,and its stability has been concerned gradually. The light source stability of FOCT is studied em?phatically in this article. The different solutions were designed according to the two main factors of temperature and drive current affecting on the stability. In the aspect of temperature control,two design schemes of temperature control circuit are put forward. Finally,the digital temperature control circuit was adopted according to the actual demands. In the aspect of drive current con?trol,based on the traditional scheme,the scheme of adjusting the drive current according to light source and light power was de?signed. The two schemes were verified in experiments. The experimental results show that the new scheme can improve the light source reliability and stability of the transducer.
