Problems solved by technology

When the secondary personnel deal with the defect of the broken fiber chain, it is difficult to find it, the positioning is inaccurate, and time is wasted
If the judgment is wrong, unplugging the normal operation of the optical fiber link will cause other failures
The processing efficiency of optical fiber link disconnection is low, which seriously affects the safe operation of smart substations
[0003] At present, most domestic mainstream network analyzer manufacturers draw data flow diagrams based on network packets,

Example Embodiment

[0022] Please check figure 1 , The method for identifying fiber optic link broken in smart substations includes the following steps,

[0023] Step 1. Build the optical fiber link node database with the optical fiber circuit number as the connection relationship, and draw the optical fiber circuit network topology diagram of the smart station;

[0024] Step 2: When the fiber link is broken, input the index information corresponding to the fiber link and call the database;

[0025] Step 3: Perform network topology scanning according to the optical fiber circuit number corresponding to the index information, and analyze all link nodes of the optical fiber disconnection.

[0026] The specific process of step 1 is: establishing an optical fiber link node database according to the optical fiber circuit table provided in the smart station design drawing; the database establishes a logical relationship based on the five elements of "plant station, dispatching point table, device, circuit, and...

Abstract

The invention discloses a method for rapidly identifying an optical fibre link-breaking point of an intelligent substation. The method comprises the steps of: (1), constructing an optical fibre link node database taking the optical fibre loop number as the connection relationship, and drawing an optical fibre loop network topological graph of the intelligent substation; (2), when optical fibre link-breaking occurs, inputting index information corresponding to optical fibre link-breaking, and retrieving the database; and (3), according to the optical fibre loop number corresponding to the index information, performing network topological scanning, and analyzing all link nodes in optical fibre link-breaking. By means of the method, the optical fibre link-breaking point can be located rapidly and accurately.

Description

technical field [0001] The invention relates to a method for quickly identifying an optical fiber disconnection point of an intelligent station. Background technique [0002] In recent years, with the rapid development of the power grid, the number of smart substations has increased year by year. Intelligent variable use optical fiber to replace the original electrical secondary circuit. However, due to the large number of optical fibers in the smart substation, the optical fiber links are complex, and the corresponding relationship between the broken link signals is not clear. Once the fiber link is broken, a large number of abnormal signals will be sent to the background monitoring machine and dispatcher. When the secondary personnel deal with the defect of the broken optical fiber chain, it is difficult to find it, the positioning is inaccurate, and time is wasted. If the judgment is wrong, unplugging the normally operating optical fiber link by mistake will cause othe...
