Application Situation of Distributed Optical Fiber Temperature Measurement Technology in Power System

Abstract:

Temperature is an important operating parameter of electrical equipment, electrical equipment operating condition obtained by monitoring the temperature information has become research focus for power system fault prediction and diagnosis^[1-. Distributed fiber optic temperature measurement system is a method for real-time measurement of the spatial distribution of temperature field sensing system. The system uses optical time domain reflectometer (OTDR) and laser Raman spectroscopy, amplifies temperature information and processes signal from wavelength division multiplexer and optical detectors, then the temperature information is displayed in real time^[4-. Distributed fiber optic temperature measurement technology has several characteristics with insulation, anti-electromagnetic interference, resistance to high voltage, resistance to chemical corrosion, and security^[6-. This article outlines the basic power system temperature monitoring content, studies the current distributed optical fiber temperature measurement technology applications in power system and prospects for its development trend.
