Description

Technical Field

[0001] The present invention relates to the field of fault traveling wave fault location, and in particular to a traveling wave fault location system and method based on artificial intelligence optimization. Background Art

[0002] With the requirement of overall aesthetic layout of industrial development, cables are increasingly used in various fields of production and life. For the sake of economic efficiency, the environment for cable laying is complex. Once a fault occurs, it is difficult to find the exact location of the fault point in time and eliminate the fault to restore power supply, which often causes significant economic losses due to power outages and production stoppages. How to quickly and accurately find the fault point and restore power supply as soon as possible has become a problem that has long plagued power workers.

[0003] Traveling wave fault location is a common method to determine the location of cable faults. In high-voltage direct current transmission, there is traveling wave ranging based on global GPS clock positioning for line faults. Fault location is performed based on the propagation time of the fault traveling wave in the line, and the traveling wave generated by the line fault is used to locate the fault. On the one hand, considering that the propagation speed of cables is different in different materials and different laying environments, there is a lack of databases that consider the effects of materials and laying environments on the traveling wave speed. On the one hand, the propagation speed of traveling waves in cables of different materials is different. When determining the location of cable faults, the staff needs to have a lot of cable maintenance experience, and the work quality of the staff is required to be high. On the other hand, the traveling wave speed is affected by the laying environment. The existing traveling wave positioning system is difficult to eliminate the influence of environmental factors on the fault location accuracy.

[0004] Therefore, people need a traveling wave fault location system and method based on artificial intelligence optimization to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a traveling wave fault location system and method based on artificial intelligence optimization to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a traveling wave fault location system based on artificial intelligence optimization, the system comprising: a clock accuracy analysis module, a laying environment analysis module, a database, a fault location analysis module and a user module;

[0007] The clock accuracy analysis module analyzes the relative error of the time when the traveling wave signal is received at both ends of the cable by measuring the ideal traveling wave speed in cables of different types;

[0008] Analyze the interference of the traveling wave velocity in different environments by using the installation environment analysis module;

[0009] The actual cable laying environment of any cable is stored in the database;

[0010] When the cable fault traveling wave is received at both ends of the cable by the fault location analysis module, the actual range of the cable fault is analyzed;

[0011] The user module displays the actual scope of the cable fault and the cable fault environment analyzed by the system to the user.

[0012] Furthermore, the clock accuracy analysis module simulates a fault traveling wave at the midpoint of any type of cable, calculates the ideal traveling wave speed through the time required for receiving the traveling wave at both ends of the cable, and analyzes the relative error of the received traveling wave signal through the time difference required for receiving the traveling wave at both ends of the cable.

[0013] Furthermore, the laying environment analysis module simulates fault traveling waves for any type of cable in any environment, calculates the environmental traveling wave speed, compares the environmental traveling wave speed with the ideal traveling wave speed, and analyzes the degree of interference of any environment on the traveling wave speed.

[0014] Furthermore, the database stores the cable laying environment, which refers to the environment where any part of any cable is located. When any cable laying environment changes, the staff updates the database.

[0015] Furthermore, the fault location analysis module determines the ideal location of the cable fault by the cable material and the time when the traveling wave is first received at both ends of the cable, calculates the ideal range of the cable fault considering the relative error of the received traveling wave signal, and calculates the actual range of the cable fault considering the cable laying environment.

[0016] The traveling wave fault location method based on artificial intelligence optimization includes the following steps:

[0017] S1: Determine the reference environment, simulate the fault traveling wave at the midpoint of any type of cable, calculate the ideal traveling wave velocity of the traveling wave in any type of cable in the reference environment, and calculate the relative error when the traveling wave signal is received at both ends of any type of cable;

[0018] S2: Conduct experiments on any type of cable in any environment, compare the environmental traveling wave velocity with the ideal traveling wave velocity, and analyze the degree of interference of any environment on the traveling wave velocity of any type of cable;

[0019] S3: When a cable fault traveling wave is received at either end of the cable, the information in the database is called to analyze the ideal position of the cable fault, the ideal range of the cable fault is calculated considering the relative error of the time of receiving the traveling wave signal, and the actual range of the cable fault is calculated considering the cable laying environment;

[0020] S4: Analyze the actual scope of the cable fault, call the cable laying environment from the database, and prompt the customer the cable fault location environment.

[0021] Further, in step S1, the system selects any environment as the reference environment. The reference environment is often the most commonly used environment for cable laying, which is conducive to reducing the error caused by environmental interference. The experiment is conducted on a cable of model I and length S. The time required for the cable a end to receive the traveling wave for the first P times is {T a_1 ,T a_2 ,…,T a_P}, the time required for the cable end b to receive the traveling wave for the first P times is {T b_1 ,T b_2 ,…,T b_P}, calculate the ideal traveling wave velocity V of the traveling wave in type I cable I :

[0022]

[0023] Where I = 1, 2, ..., N, I represents the Ith cable model among the N cable models in the system experiment, and the relative error α when the two ends of the cable with a length of S receive the traveling wave signal for the Qth time is analyzed. Q :

[0024]

[0025] Where Q = 1, 2, ..., P, when Q = 1, define T a_0 =0, T b_0 =0, calculated and compared one by one

[0026] {α1,α2,…,α P}, the relative error when the two ends of the cable receive the traveling wave signal α=max(α1,α2,…,α P ), the calculated data information is stored in the database. The relative error has nothing to do with the cable material, but is affected by the clock accuracy when the two ends of the cable receive the traveling wave signal. Considering the relative error, the accuracy is increased without changing the hardware cost;

[0027] Further, in step S2, an experiment is conducted on a cable of model I and length S. There are n environments in which users use the cable. The cable is laid in the i-th environment, and a fault traveling wave is simulated at the midpoint of the cable. The traveling wave velocity V of the cable of model I in environment i is calculated. I_i , respectively, in these n environments, the environmental traveling wave velocity {V I_1 ,V I_2 ,…,V I_3}, calculate the interference degree of environment i on the traveling wave velocity in cable type I, β I_i :

[0028] β I_i =V I_i -VI ;

[0029] Where i = 1, 2, ..., n, one by one into {I = 1, 2, ..., N}, calculate the interference degree of environment i on the traveling wave velocity in N types of cables respectively {β 1_i ,β 2_i ,…,β N_i}, store the calculated data information into the database, and establish a database of the speed of traveling waves in cables of different materials to provide a guarantee for the subsequent fault location analysis.

[0030] Further, in step S3, when the cable fault traveling wave is received at both ends of any faulty cable, the system marks one end of the cable as end a and the other end as end b, and the time point at which the faulty cable end a receives the traveling wave signal is t a The time point when the cable end b receives the traveling wave signal is t b The system searches the database and finds that the faulty cable model is I, the cable length is L, and the speed of the traveling wave in the i-th environment is V I_i , the relative error when the two ends of the cable receive the traveling wave signal is α, and the ideal position of the cable fault refers to: when the cable laying environment is completely regarded as the reference environment, the distance L from the cable end a a The position of L a :

[0031]

[0032] Considering the relative error α of the received traveling wave signal, the ideal range of cable fault is calculated. The ideal range of cable fault refers to: when considering the relative error α, the set of distances between the cable fault position and the cable end a (L a -0.5m, L a +0.5m), calculate the ideal range of cable fault fluctuation length m:

[0033]

[0034] The system retrieves cable information from the database. The length of the faulty cable from the ideal position of the cable fault to the cable end a in the laying environment i is L. a_i , one by one, the distance from the cable a end in n environments is {L a_1 ,L a_2 ,…,L a_n}, the distances from the cable end b in n environments are {L b_1 ,L b_2 ,…,L b_n}, considering the cable laying environment to calculate the actual range of cable faults (L a -0.5m-0.5M, L a+0.5m+0.5M), calculate the fluctuation length M of the actual range of cable fault affected by environmental interference:

[0035]

[0036] Taking into account that the actual range of cable faults is affected by relative errors and environmental interference, the error caused by interference is reduced while judging the cable fault location, providing users with a more accurate actual range of cable faults.

[0037] Furthermore, in step S4, the system compares the actual scope of the cable fault with the cable laying environment stored in the database, prompts the user of the faulty cable, and indicates the actual scope of the cable fault and the corresponding environment in the pipeline diagram for the user, thereby reducing the time for the user to go back and forth to confirm the fault environment and reducing the workload of manual work.

[0038] Compared with the prior art, the beneficial effects achieved by the present invention are: the traveling wave ranging fault location based on global GPS clock positioning is used to replace manual experience judgment, thereby reducing the uncertainty caused by manual labor. On the one hand, considering that the propagation speed of cables under different materials and different laying environments is different, a database considering the influence of materials and laying environments on the traveling wave speed is provided; on the other hand, considering that the traveling wave speed is affected by the laying environment, the laying environment interference is taken into account while calculating the cable fault location, so as to provide users with a more accurate actual range of the cable fault.

[0053] The traveling wave fault location method based on artificial intelligence optimization includes the following steps:

[0054] S1: Determine the reference environment, simulate the fault traveling wave at the midpoint of any type of cable, calculate the ideal traveling wave velocity of the traveling wave in any type of cable in the reference environment, and calculate the relative error when the traveling wave signal is received at both ends of any type of cable;

[0057] S4: Analyze the actual scope of the cable fault, call the cable laying environment from the database, and prompt the customer the cable fault location environment.

[0058] In step S1, the system selects any environment as the reference environment. The reference environment is often the most commonly used environment for cable laying, which is conducive to reducing the error caused by environmental interference. The experiment is conducted on a cable of model I and length S. The time required for the cable a end to receive the traveling wave for the first P times is {T a_1 ,T a_2 ,…,T a_P}, the time required for the cable end b to receive the traveling wave for the first P times is {T b_1 ,T b_2 ,…,T b_P}, calculate the ideal traveling wave velocity V of the traveling wave in type I cable I :

The relative error has nothing to do with the cable material, but is affected by the clock accuracy when the two ends of the cable receive the traveling wave signal. Considering the relative error, the accuracy is increased without changing the hardware cost;

[0064] In step S2, an experiment is conducted on a cable of model I and length S. There are n environments in which users use the cable. The cable is laid in the i-th environment, and a fault traveling wave is simulated at the midpoint of the cable. The traveling wave velocity V of the cable of model I in environment i is calculated. I_i , respectively, in these n environments, the environmental traveling wave velocity {V I_1 ,V I_2 ,…,V I_3}, calculate the interference degree of environment i on the traveling wave velocity in cable type I, β I_i :

[0068]

[0069] Considering the relative error α of the received traveling wave signal, the ideal range of cable fault is calculated. The ideal range of cable fault refers to: when considering the relative error α, the set of distances between the cable fault position and the cable end a (L a -0.5m, L a +0.5m), calculate the ideal range of cable fault fluctuation length m:

[0070]

[0071] The system retrieves cable information from the database. The length of the faulty cable from the ideal position of the cable fault to the cable end a in the laying environment i is L. a_i , one by one, the distance from the cable a end in n environments is {L a_1 ,L a_2 ,…,L a_n}, the distances from the cable end b in n environments are {L b_1 ,L b_2 ,…,L b_n}, considering the cable laying environment to calculate the actual range of cable faults (L a -0.5m-0.5M, L a +0.5m+0.5M), calculate the fluctuation length M of the actual range of cable fault affected by environmental interference:

[0075] Embodiment 1: When the system detects that both ends of the faulty cable receive the cable fault traveling wave, the system marks one end of the cable as end a and the other end as end b. The time point at which the faulty cable end a receives the traveling wave signal is t a The time point when the cable end b receives the traveling wave signal is t b , we can calculate t a -t b =1, the system searches the database and finds that the faulty cable model is I, the cable length is 2000, the speed of the traveling wave is 400 in the reference environment, and the relative error when the two ends of the cable receive the traveling wave signal is 20.

The length of the faulty cable from the ideal position of the cable fault to the cable end a in the laying environment i is L. a_i , one by one, the distance from the cable a end in n environments is {L a_1 ,L a_2 ,…,L a_n}, the distances from the cable end b in n environments are {L b_1 ,L b_2 ,…,L b_n}, considering the cable laying environment, calculate the actual range of cable faults (1196.5-0.5M, 1204.5+0.5M), and calculate the fluctuation length M of the actual range of cable faults affected by environmental interference:

[0080]

[0081] Substituting the data in the database, we can calculate M=20. Considering that the actual range of cable faults is affected by relative errors and environmental interference, the error caused by interference is reduced while determining the cable fault location, providing users with a more accurate actual range of cable faults, that is, the actual range of cable faults (1186.5, 1214.5);

Considering that the speed of the traveling wave is affected by the laying environment, the interference of the laying environment is taken into account when calculating the cable fault location, and providing users with a more accurate actual scope of the cable fault.
