摘要:
为提高测量电流的实时性和准确性，设计了适用于振动、应变、磁场和温度等多物理场的GMM-FBG光学电流传感器。分析了光纤布拉格光栅（FBG）的光学传感特性，构建了超磁致伸缩材料（GMM）的一维非线性模型和磁热耦合模型。组合封装GMM和FBG的传感探头，构建磁路系统和解调系统，校正了传感器的相位误差，设计并实现了GMM-FBG光学电流传感器实物。分析了温度特性，从不同磁场方向进行电流响应实验，验证了温度补偿方法。GMM-FBG光学电流传感器取消了温度换算，降低了计算量，实现了传感器的温度补偿，提高了实时测量精度。该研究面向数字化、智能化的复杂电力系统，为新型光学电流传感器的开发与优化提供了技术参考。
Abstract:
In order to improve the real-time performance and accuracy of current measurement, a GMM-FBG optical current sensor suitable for multi-physical fields such as vibration, strain, magnetic field and temperature was designed. The optical sensing properties of Fiber Bragg Grating (FBG) were analyzed, and the one-dimensional nonlinear model and magneto-thermal coupling model of Giant Magnetostrictive Material (GMM) were constructed. The sensor probes of GMM and FBG were combined and packaged, the magnetic circuit system and demodulation system were constructed, the phase error of the sensor was corrected, and the actual GMM-FBG optical current sensor was designed and realized. The temperature characteristics were analyzed, and current response experiments were carried out from different magnetic field directions to verify the temperature compensation method. The GMM-FBG optical current sensor canceled the temperature conversion, reduced the calculation amount, realized the temperature compensation of the sensor, and improved the real-time measurement accuracy. This research is oriented to digital and intelligent complex power systems, and provides a technical reference for the development and optimization of new optical current sensors.
