Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1a is a flowchart of a bird damage monitoring method for a power transmission line according to an embodiment of the present invention, and fig. 1b is a structural diagram of a full connection layer classifier according to an embodiment of the present invention, which is applicable to a case where an OPWG optical cable is used to detect a bird damage condition of a power transmission line, where the method may be executed by a bird damage monitoring device for a power transmission line, and the bird damage monitoring device for a power transmission line may be implemented by software and/or hardware, and may be configured in computer equipment, such as a mobile phone, a tablet computer, and wearable equipment (e.g., a smart watch, smart glasses, etc.).
In the embodiment of the invention, an overhead ground wire consisting of a plurality of sections of OPWG optical cables connected in sequence is arranged on the transmission line, a signal acquisition device is arranged between two adjacent sections of OPWG optical cables, the signal acquisition device sends initial information of received optical signals from the previous section of OPWG optical cable to an upper computer, and sends optical signals consistent with the initial information to the next section of OPWG optical cable.
That is, in the embodiment of the present invention, the overhead ground wire uses the OPWG optical cable, and a signal collecting device is disposed at a certain distance to collect and forward the signal of the OPWG optical cable. The signal acquisition device acquires initial information of the optical signal transmitted by the previous section of OPWG optical cable and re-acquires the optical signal which is consistent with the optical signal transmitted by the previous section of OPWG optical cable from the next section of OPWG optical cable according to the initial information. The signal acquisition device is arranged between the two sections of OPWG optical cables, so that the optical signals transmitted by the OPWG optical cables can be acquired, the whole section of OPWG optical cables is divided into a plurality of sections, the bird damage position can be conveniently positioned in the later period, and the condition that the optical signals transmitted in the OPWG optical cables are seriously attenuated to influence the detection of the OPWG optical cables at the subsequent positions can be avoided.
An OPGW Optical cable (Optical Fiber Composite Overhead Ground Wire) is a Composite Overhead Ground Wire integrating Ground Wire and communication functions, and an Optical Fiber is placed in a Ground Wire of an Overhead high-voltage power transmission line to form an Optical Fiber communication network on a power transmission line.
In the embodiment of the invention, when the insulator is polluted and flashed by bird damage, leakage current is formed on the surface of the OPWG optical cable, and the optical signal in the OPGW optical fiber generates Faraday magneto-optical effect under the action of a magnetic field generated by the leakage current, so that the polarization state of the optical signal in the OPGW optical fiber is changed, and therefore, whether the pollution and flash caused by bird damage occur to the insulator can be monitored by detecting the change of the polarization state of the optical signal. Wherein, Faraday magneto-optical effect means: when a linearly polarized light signal propagates in the OPGW optical cable, if a strong magnetic field is applied in a direction parallel to the propagation direction of the optical signal, the vibration direction of the optical signal is deflected, the deflection angle ψ is proportional to the product of the magnetic induction B and the length l of the light passing through the medium, that is, ψ is VBl, and the proportionality coefficient V is called the verdet constant and is related to the medium property and the optical wave frequency. The direction of deflection depends on the media properties and the magnetic field direction. That is, when insulator contamination flashover occurs due to bird damage, a leakage current flowing through the OPGW optical cable forms an electromagnetic field on the surface of the OPGW optical cable, and the electromagnetic field changes the vibration direction of an optical signal propagating through the OPGW optical cable.
The method specifically comprises the following steps:
and step 110, acquiring initial information from the signal acquisition device and equipment information of the signal acquisition device.
In the specific implementation, the optical signal transmitted by the OPWG optical cable of the power transmission line is acquired through the signal acquisition device, the initial information of the optical signal of the OPWG optical cable corresponding to the acquisition position of the signal acquisition device and the equipment information corresponding to the signal acquisition device are finally obtained, the running condition of the OPWG optical cable of each part of the power transmission line can be monitored by combining the equipment information and the initial information in the later period, and the monitoring efficiency of the working condition of the OPWG optical cable is effectively improved.
In other embodiments, the number of the signal acquisition devices is not limited, and the signal acquisition devices may be one or more, and in the case of one signal, the signal attenuation rate of the OPWG optical cable and the receiving time of the optical signal may be combined to determine the position of the optical signal of the OPWG optical cable where the optical signal is deflected, so as to realize the positioning of the position where the bird damage is caused, and when a plurality of signal acquisition devices are provided, the position of the signal acquisition devices may be combined to realize more reliable positioning.
In embodiments of the present invention, the initial information may include the type, characteristic parameters, etc. of the polarized optical signal, such as the amplitude, intensity, phase, frequency, polarization, etc. parameters of the optical signal. Even further include the length of the OPGW cable, attenuation coefficient, chromatic dispersion coefficient mode field diameter, cutoff wavelength, zero dispersion slope, and the like. The equipment information may include an equipment number of the signal acquisition device, an equipment operation parameter, and the like.
And step 120, reading corresponding expert scoring data from a preset historical database based on the equipment information.
In the embodiment of the present invention, a history database containing bird damage history data is pre-established, and the history database may include the position and number of the OPWG optical cable corresponding to the position of the signal acquisition device, and may further include the frequency of occurrence of the bird damage hazard at the corresponding position, the line geographical location information, and the like, for example: distance between the line and the river, distance between the line and the lake, distance between the forest zones, distance between bird migration channels and the like. In addition, the data stored in the history database may be preprocessed, and may be directly used without additional processing after being read.
The expert scoring data is a method for scoring a certain index or scoring the relation between indexes by using the deep experts in the field, and complex data is processed. The method is applied to two places, one is that non-numerical indexes such as river conditions around lines, lake conditions, forest zone conditions and bird migration channel conditions are scored by experts according to distances between the lines and the rivers, distances between the lakes and the forest zone, distances between the birds and the bird migration channel in historical data, and bird damage reference values of different non-numerical indexes are obtained finally after normalization calculation and used for subsequent calculation. And secondly, scoring all indexes according to the importance of the indexes, and endowing different weights to different indexes according to scoring results. And the scoring result of the expert, and the non-numerical index bird damage reference value and the index weight obtained according to the scoring result are stored in a historical database.
And step 130, calculating the probability of the bird damage hidden danger based on the initial information and the expert scoring data.
In the step, whether the OPWG optical cable flows through leakage current or not can be determined according to the change of the optical signal transmitted in the OPWG optical cable, and then whether the OPWG optical cable changes caused by bird damage or not is judged, and the probability of occurrence of the hidden danger of bird damage can be effectively judged by combining the historical database. For the probability calculation, for example, a full-connection layer neural network classifier is constructed, the initial information and the expert scoring data are input into the full-connection layer neural network classifier as input for classification calculation, and the probability of occurrence of the bird damage hidden danger is finally obtained. In other embodiments, other means may be used for calculation, for example, a specific calculation formula is set, the collected initial information and expert scoring data are quantized, different weights are set according to different influences of the parameters, and the probability of the bird damage is calculated.
The technical scheme of this embodiment, through the initial information of the optical signal of gathering the inside transmission of OPWG optical cable and the equipment information of signal acquisition equipment, the expert's score data that combines to store in the historical database of predetermineeing calculates the emergence probability of OPWG optical cable bird damage hidden danger, can effectually borrow the bird damage hidden danger control of the transmission line that realizes by OPWG optical cable, the staff can arrange the maintenance maintainer to inspect and maintain corresponding transmission line according to the emergence probability size of bird damage hidden danger, avoid needing to make the loss that brings when responding to again after the bird damage takes place even causes certain influence.
In the embodiment of the present invention, after step 130, the method may further include:
and step 140, sending out an alarm based on the probability and the equipment information.
In a specific implementation, after the occurrence probability of the bird damage hidden danger is obtained through calculation, different responses can be made according to the size of the occurrence probability, for example, a warning is issued after the occurrence probability is greater than a preset value, and the content and the level of the warning issued in different preset ranges are different. Or, the warning is given out and the equipment information of the signal acquisition device corresponding to the warning is attached, so that the working personnel can make corresponding response more conveniently. The warning information and the equipment information can be combined according to a specific format form and then sent out, and the warning information and the equipment information are displayed to the staff through a display device or other means. In addition, the corresponding initial information and the corresponding equipment information can be packaged, uploaded and stored, so that the subsequent checking and rechecking of workers are facilitated.
In an embodiment of the present invention, step 120 may include:
and step 121, acquiring the equipment number of the signal acquisition device from the equipment information.
In the embodiment of the present invention, the device information of the signal acquisition device is appended with the device number corresponding to the signal acquisition device, and the number may be obtained by arranging the signal acquisition device in advance, or may be defined according to a fixed acquisition sequence in actual use, which is not limited too much here.
And step 122, reading corresponding expert scoring data from a preset historical database by taking the equipment number as a keyword.
In specific implementation, the data in the historical database are all associated with the equipment numbers, and the data in the historical database can be retrieved and read by taking the equipment numbers as keywords, so that expert scoring data corresponding to the signal acquisition device is obtained.
In an embodiment of the present invention, step 130 may include:
and 131, normalizing the initial information to obtain transition information.
And 132, carrying out normalization processing on the expert scoring data to obtain a transition score.
In the specific implementation, the initial information and the expert scoring data are respectively subjected to normalization processing, so that the initial information and the expert scoring data can be unified, and subsequent calculation is facilitated. The specific normalization methods are many, such as Z-score method, digital normalization, etc., and can be selected according to specific situations.
In an optional example, performing normalization processing on the initial information by using a Z-score method to obtain transition information; and carrying out normalization processing on the expert scoring data by adopting a digital normalization method to obtain a transition score.
In an embodiment of the present invention, the initial information may include a polarized light polarization angle, a polarized light amplitude, and a polarized light frequency of the optical signal of the OPWG optical cable collected by the signal collection apparatus.
The initial information may be normalized using the following equation (1):
wherein θ' represents the result after normalization, θ represents the polarization angle, the amplitude or the frequency of the polarized light in the initial information, and θ mean And σ represents a standard deviation of all sample data of the polarized light polarization angle, the polarized light amplitude or the polarized light frequency in the initial information.
The historical database can selectively comprise historical bird damage occurrence frequency f, bird damage occurrence line section number ai and line geographic position information (distance m between a line and a river) 1 Lake distance m 2 Distance m between forest zones 3 Bird migration channel distance m 4 )。
The historical bird occurrence frequency f can be normalized by the descending step model equation (2):
geographical location information of the line (distance m between the line and the river) 1 Lake distance m 2 Distance m between forest zones 3 Bird migration channel distance m 4 ) And carrying out normalization by using an expert evaluation mode. The specific process is that a total of P experts with different resource depths in the field are set, and the jth expert has different distances m i Two corresponding bird damage reference values m are given ij1 And m ij2 Averaging all expert results to obtain a bird damage reference value:
and the normalization results for the different distances mi are calculated using the following equation (5).
Wherein m' i At different distances m i Normalized result of (2)，m i1 And m i2 Bird damage reference values assessed for two experts.
And step 133, splicing the transition information and the transition scores into a target vector.
In the previous steps, the polarization angle, the amplitude and the frequency of the polarized light and the distance m between the line and the river are respectively calculated 1 Lake distance m 2 Distance m between forest zones 3 Bird migration channel distance m 4 All the normalized values need to be taken as k-dimensional vectors (k is the number of the normalized parameters) in this step.
Optionally, weights may be introduced to correct the influence of each parameter, that is, each component of the k-dimensional vector is multiplied by the weight, and the specific weight is set by an expert according to an actual situation.
And 134, inputting the target vector into a pre-trained full-link classifier to obtain the probability of the bird damage hidden danger.
In specific implementation, a full-connection layer neural network classifier can be adopted to input the k-dimensional vectors in front and calculate the probability of bird damage hidden danger.
