National standard specification for technical indicators of DTS distributed fiber optic temperature measurement system

DTS distributed fiber optic temperature measurement system: a sensing system that can monitor the temperature measurement points of multiple objects and measure the spatial temperature field distribution online. It is a distributed, continuous, and functional fiber optic temperature measurement system. In the system, optical fibers not only play a photosensitive role, but also guide light. By utilizing the temperature effect of backward Raman scattering in optical fibers, real-time measurement of the temperature field in which the fiber is located can be achieved; The use of optical time-domain reflection technology (OTOR) can accurately locate measurement points. A professional fiber optic temperature measurement manufacturer in China has independently developed multiple fiber optic temperature measurement systems and has a leading invention patent in China.

National standard specification for technical indicators of DTS distributed fiber optic temperature measurement system
1) The standard proposes technical requirements for temperature measurement optical cables, temperature measurement hosts, and monitoring and calculation software. The standard provides comprehensive technical requirements for temperature measurement hosts, including real-time online monitoring of cable line operating temperature, measurement and positioning of thermal points, data communication formats, and alarm functions. The standard provides comprehensive requirements for monitoring and calculation software, including cable conductor temperature calculation, cable line dynamic current carrying capacity calculation, data storage, and time identification.

Through these regulations, the technical requirements for the functions of distributed fiber optic temperature measurement systems for power cables have been further unified and standardized, enabling the basic functions of distributed fiber optic temperature measurement systems applied to power cable line temperature measurement to be comprehensively standardized.

2) The standard lists the technical requirements for temperature measurement optical cables, temperature measurement hosts, and monitoring and calculation software. Among them, channel attenuation requirements are specified for temperature measurement optical cables. Nine technical indicators have been specified for the temperature measurement host, including temperature measurement range, temperature measurement accuracy, spatial resolution, temperature resolution, single pass measurement time, positioning accuracy, alarm, average failure time, and power supply voltage; The monitoring and calculation software mainly specifies technical indicators such as accuracy of conductor temperature calculation, system delay, communication protocol, data storage time limit, and annual data integrity rate.

The regulations on these technical indicators in the standard are determined according to the technical requirements of the power company for optical fiber temperature measurement equipment and the production realization capacity of mainstream manufacturers, which balances the technical economy and progressiveness, and moderately improves the network access technical requirements of distributed optical fiber temperature measurement products.

3) The standard lists specific inspection requirements for five types of tests, including type testing, factory testing, on-site acceptance, on-site verification, and special testing, for distributed fiber optic temperature measurement systems. The standard provides test requirements for the electromagnetic compatibility performance and environmental adaptability performance of temperature measurement hosts in the main text; The appendix provides test methods for temperature measurement range, temperature measurement accuracy, temperature resolution, spatial resolution, positioning accuracy, single channel measurement time, alarm function, conductor temperature calculation verification, dynamic current carrying capacity calculation verification, communication function, channel attenuation, and system delay.

These experimental aspects are formed based on the inspection and testing methods of distributed fiber optic temperature measurement products by testing units, power companies, and manufacturers, which can effectively detect the technical performance of the products and have a certain degree of operability.
