전력 시스템 보호를 위한 광섬유 격자 온도센서의 정밀도 개선
Accuracy improvement of FBG temperature sensor system for usage in electric power systems
- 발행 : 2005.05.13
초록
A distributed FBG temperature sensor system was constructed for the use in protection of electric power system. A F-P wavelength tunable filter is used converting temperature-induced wavelength variations to temporal peak locations. We used Gaussian line-fitted algorithm to alleviate the error caused by quantization and electrical noises. The experimental results showed much better accuracy than the raw peak-detection scheme.
