Temperature Measurement Algorithm based on Fiber Bragg Grating for Intelligent Electrical Equipment

The temperature change of the key points of electrical equipment plays an important warning role in the safe and stable operation of the power grid. In order to solve the problem of large real-time temperature measurement error of electrical equipment and ensure the safety of electrical equipment and transmission efficiency of power system, an intelligent fiber Bragg grating (FBG) temperature measurement algorithm for electrical equipment is studied in this paper. The temperature information of the scattering region is obtained by detecting the ratio of the intensity of Stokes light to that of anti-Stokes light. The principle of on-line temperature monitoring of all-optical fiber gate electrical equipment is to compare and analyze the temperature data of electrical equipment measured by the system and the temperature data of normal operation of electrical equipment. The experimental results show that the proposed algorithm can improve the SNR of the sampled voltage signal effectively, and the temperature measurement accuracy is higher and the effectiveness is stronger.
