Method for monitoring power equipment in cable pit online through optical fiber sensing technology

Abstract

The invention discloses a method for monitoring power equipment in a cable pit online through an optical fiber sensing technology, comprising the following steps: optical fiber sensors are installed in a cable pit, and an optical cable is laid into a nearest station and connected to computer control equipment; the computer control equipment analyzes spectral data according to parameter characteristics, and acquires monitoring values of the sensors; the monitoring data is accessed to the Intranet of the power company and collected into an 'intelligent operation and maintenance control platform', and the data is analyzed and judged according to a cable refining module algorithm model to get working state data of equipment in the cable pit; and fault analysis or maintenance analysis is made on the field equipment according to the working state data of the equipment, and alarm information is produced in a timely manner if abnormality is found. According to the method, the working states of field equipment bodies and channels are analyzed and judged based on monitoring data acquired on site and in real time and according to the control logic of the algorithm model, abnormality is found and the alarm is raised in a timely manner, the work efficiency of operation and maintenance is improved, and the work intensity of operation and maintenance personnel is reduced.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to a method for realizing on-line monitoring of cable well electric equipment through optical fiber sensing technology. Background technique [0002] The smart distribution network is the basic link and an important part of the construction of the smart grid. It is the source of basic operation data collection and the command execution unit of the power grid. It is also a new stage in the development of distribution network automation technology. With the in-depth application of the Internet of Things technology in the field of power grid operation, the detailed information of the cable body and channels can be obtained in real time through optical fiber sensors in the cable shaft, and abnormal situations can be found in time through data analysis and judgment, which has greatly promoted the distribution network intelligence. construction. [0003] Compared with the current detection te...
