Description
Technical Field
The invention belongs to the technical field of power communication, and particularly relates to a method and a system for joint diagnosis of a power communication network and relay protection 2M channel faults.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The current secondary systems such as power grid system protection, stability control system, relay protection and the like are seriously dependent on the communication system, and the secondary system is withdrawn or fails, so that the primary system can be possibly changed. Therefore, the safe operation of the communication system is directly related to the safety and stability of the power grid, and important business on the power grid is ensured not to fail due to unfavorable communication support.
Relay protection is a first defense line for safe operation of a power grid, has the characteristics of short transmission time, sensitive transmission delay and the like, and ensures that a relay protection channel runs safely and stably as a primary responsibility of an electric power communication network. Therefore, once the relay protection channel is abnormal, the relay protection channel must be repaired within the shortest possible time so as to ensure the running stability of the power grid. The power grid operation relay protection service is mainly divided into a special optical fiber protection channel and a multiplexing optical fiber protection channel 2 types, and after the protection channel is abnormal, the problems of unclear fault point positioning, low fault handling efficiency of a cross-department and the like are easy to occur.
At present, a mode of multiplexing 2M is adopted for carrying relay protection service channels in an electric power communication network (SDH optical transmission network), as shown in fig. 1, most relay protection devices are directly connected with optical transmission equipment without unified optical interfaces, interface matching is realized by photoelectric conversion equipment (such as a MUX-2M signal digital multiplexing interface device, namely a MUX digital multiplexing interface device) between the protection devices, namely the optical signals of the relay protection devices are converted into 2Mbit/s electric signals through the MUX digital multiplexing interface device, and then the 2M electric interfaces of the service channels of the SDH equipment (namely the SDH transmission equipment) are connected through coaxial cables, so that the 2Mbit/s electric signals are transmitted to the SDH optical transmission network (SDH transmission network), and then the protection signals are transmitted to an opposite relay protection device through the SDH transmission network. This transmission mode has the following 2 common problems:
1. and the fault positioning is difficult in the operation and maintenance process. From the end-to-end communication connection of the protection device, the signal intermediate conversion process is complex, the repeated conversion process of optical signal-electric signal-optical signal is carried out, and a large number of coaxial cable jumpers and jumper connection optical fibers are complex in implementation, more in fault nodes and poor in maintainability.
2. The equipment connection is complex, the MUX digital multiplexing interface device cannot be monitored by a network manager, and most MUX devices are powered by a single power supply, so that higher running risks exist.
Particularly in the aspect of fault location, if error codes or channel abnormality alarms occur in the protection device, as the multiplexing channels pass through all levels of communication equipment, all levels of equipment are monitored by different systems, alarm information cannot be integrated, two professions of communication and protection have difficulty in quickly judging fault points, and the fault points can only be checked in a sectional self-loop mode; especially when the two sides of the line belong to different operation and maintenance units, the problems can be checked only by closely matching each professional of each unit, and the problems of skin pushing, skin tearing and the like are easy to occur.

In order to realize the joint diagnosis of the first 2 modes under the above 3 bearing modes, the invention adopts the following technical scheme:

Specifically, the specific scheme of the implementation can be realized by referring to the following contents:
as shown in fig. 4, the relay protection device accesses the protection information sub-station device (protection information sub-station device) through the relay protection device network; the SDH transmission equipment is accessed into a network manager (SDH transmission network manager server) through an optical transmission network; the message-keeping substation device and the SDH transmission network management server are connected to the fault collaborative diagnosis device; the fault collaborative diagnosis device is also connected with a diagnosis result confirmation end; the fault collaborative diagnosis device is used for carrying out fault collaborative diagnosis analysis on the relay protection channel, integrating analysis on the interruption alarm of the protection channel of the information-protection substation and the operation state of the protection channel of the power communication network, and screening fault points step by step through a fault studying and judging algorithm to locate fault reasons.
The relay protection channel fault joint diagnosis analysis realizes the joint diagnosis of the position of the fault point by establishing a network management alarm joint analysis mechanism of the information protection substation and the power communication network, effectively shortens the treatment time when the service fault occurs, improves the fault treatment linkage efficiency, and has the following process as shown in fig. 7:

If the service channel 2M port does not report the electric signal loss alarm information, and meanwhile, the power communication network side 2M port does not report the remote alarm information, and the relay protection device optical interface reports the optical signal loss alarm information, judging that the link between the relay protection device and the MUX digital multiplexing interface device is faulty (fiber cable or interface fault).
If the service channel 2M port does not report the electric signal loss alarm information, and meanwhile, the electric power communication network side 2M port does not report the remote alarm information, and the relay protection device optical interface does not report the optical signal loss alarm information, organizing each professional to loop back and check section by section.
Step 5, if the service channel 2M port reports the optical signal loss alarm information, the alarm information of the information-retaining substation system is combined for research and judgment, namely, if the relay protection device reports the optical interface signal loss alarm information at the same time, the bare optical fiber or the optical module corresponding to the alarm is judged to have faults, and the fault point can be accurately positioned to the single-core optical fiber according to the SDH transmission equipment and the optical module alarm information of the relay protection device;
if the service channel 2M port does not report the optical signal loss alarm information, the power communication network side 2M port does not report the remote alarm information, and the relay protection device does not report the optical interface signal loss alarm information, the method is matched with the site for further investigation;
if the service channel 2M port does not report the optical signal loss alarm information, and meanwhile, the power communication network side 2M port reports the remote alarm information, the power communication network fault is preliminarily judged, and the fault point position can be continuously analyzed according to the alarm condition in the power communication network.
The reasons for reporting the optical signal loss alarm information by the relay protection device include: optical module faults of relay protection devices, bare fiber faults among devices and the like;
reasons for reporting the optical signal loss alarm information by the service channel 2M port include: SDH equipment 2M port optical module failure, bare fiber failure between devices, etc.
And 6, after the combined diagnosis is initially completed, sending the analysis result to a diagnosis result confirmation terminal, further pushing the diagnosis result to a dispatching attendant, and simultaneously sending the diagnosis result to each professional monitoring system, further pushing the diagnosis result to a related professional operation and maintenance team, and enabling the corresponding profession to be responsible for mainly checking hidden dangers of fault points, as shown in fig. 8.
