| Abstract: | Traditional infrared temperature measurement is only able to measure partial position of power system which is not able to satisfy requirement for power grid development. Aiming at this requirement, this paper introduces basic principle and realization method of distributed fiber temperature measuring system based on Raman scattering. Taking 220 kV cable line engineering of Zhuhai Hengqin substation-Macao Lianhua substation as an example, it verifies application effect of distribu- ted fiber temperature measuring system in 220 kV power cable. Temperature measuring result is in accordance with reality which is satisfying requirement for equipment operation and indicates that the distributed fiber temperature measuring system is provided with merits of stable reliability and high precision for temperature measurement. |
