[0030] In this embodiment, a method for troubleshooting an alarm channel of a relay protection test that runs on a mobile terminal, a computer terminal, or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 This is a flow chart of a method for troubleshooting an alarm channel of a relay protection test according to an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0032] Step S201, obtaining current alarm information issued by the current relay protection test, and determining the electronic device involved in the current alarm information;

[0033] Specifically, during the relay protection test, if a device fails and issues an alarm message, the alarm message issued by the system is collected, and based on the alarm message issued by the current relay protection test, the electronic device that may be related to the alarm message is analyzed, so as to promptly deal with potential problems by analyzing whether there is a fault in the electronic device to ensure the normal operation of the system.

[0034] Step S202: Acquire alarm channels between the electronic devices, and construct an alarm channel matrix between the electronic devices based on the alarm channels. The alarm channels are communication paths between the electronic devices for receiving and transmitting information, and the elements of the alarm channel matrix are used to indicate whether the alarm channels exist between the electronic devices.

[0035] Specifically, the communication connections between various electronic devices are analyzed, and a matrix is ​​established to describe the communication transmission path between them. This path is a channel for sending and receiving information. The matrix is ​​defined as an alarm channel matrix. The elements of the alarm channel matrix indicate whether there is an alarm transmission path between each pair of electronic devices, so as to ensure that the association relationship between each pair of devices is fully understood, and that each pair of devices can accurately transmit communication information and respond in a timely manner.

[0036] Step S203: determining the faulty electronic device among the electronic devices based on the alarm information, and constructing an alarm data matrix based on the normal electronic devices and the faulty electronic devices, wherein the elements in the alarm data matrix are respectively used to indicate whether each electronic device has a fault, and the elements in the alarm data matrix correspond one-to-one to the unique identifiers of the electronic devices;

[0037] Specifically, based on the alarm information issued by the current relay protection test, determine which devices have faults, and establish a matrix based on normal electronic equipment and faulty electronic equipment. The matrix is ​​defined as an alarm data matrix to indicate whether each device has a fault. Each electronic device corresponds to a unique identifier, and each element in the matrix corresponds one-to-one with the unique identifier of the electronic device. This allows for a clearer understanding of the specific information and fault status of each device. By establishing an alarm data matrix, we can more effectively identify and locate equipment faults, thereby speeding up subsequent troubleshooting and repair.

[0038] Step S204: Calculate the product of the alarm channel matrix and the alarm data matrix to obtain a fault matrix, where the elements in the fault matrix are used to indicate whether the corresponding electronic device has a faulty alarm channel, and the elements in the fault matrix correspond one-to-one to the unique identifier of the electronic device.

[0039] Specifically, the alarm channel matrix and the alarm data matrix are multiplied to obtain a fault matrix. The elements in the fault matrix indicate whether the corresponding electronic device has a fault alarm channel. By calculating the fault matrix, we can more accurately identify which electronic devices have fault alarm channels and need attention and processing, and take measures to repair the problems. In addition, each element of the fault matrix corresponds to the unique identifier of the electronic device, so that the specific information and fault status of each device can be more clearly understood.

[0040] Step S205 : troubleshooting the alarm channels of the electronic devices according to the fault matrix.

[0041] Specifically, the fault matrix is ​​used to troubleshoot each electronic device with a faulty alarm channel. During the troubleshooting process, it is necessary to analyze the faulty electronic devices in the fault matrix and the alarm data matrix, determine which electronic devices may have faulty alarm channels, and then check each electronic device with a potentially faulty alarm channel to confirm whether there is a fault or abnormality. This process continues until the specific location and cause of the faulty alarm channel are determined. The faulty alarm channel is then repaired to ensure normal communication between the electronic devices until the alarm information is no longer issued.

[0042] Through this embodiment, in the above-mentioned alarm channel fault troubleshooting method for a relay protection test, current alarm information issued by the current relay protection test is obtained, and the electronic device involved in the above-mentioned current alarm information is determined; the alarm channels between each of the above-mentioned electronic devices are obtained, and an alarm channel matrix between each of the above-mentioned electronic devices is constructed based on the above-mentioned alarm channels. The above-mentioned alarm channels are communication paths for receiving and transmitting information between each of the above-mentioned electronic devices, and the elements of the above-mentioned alarm channel matrix are respectively used to indicate whether the above-mentioned alarm channels exist between each of the above-mentioned electronic devices; the above-mentioned electronic devices that have failed are determined based on the above-mentioned alarm information, and an alarm data matrix is ​​constructed based on the normal electronic devices and the above-mentioned faulty electronic devices. The elements in the above-mentioned alarm data matrix are respectively used to indicate whether each of the above-mentioned electronic devices has failed, and the elements in the above-mentioned alarm data matrix correspond one-to-one to the unique identifier of the above-mentioned electronic device; the product of the above-mentioned alarm channel matrix and the above-mentioned alarm data matrix is ​​calculated to obtain a fault matrix, and the elements in the above-mentioned fault matrix are used to indicate whether the corresponding above-mentioned electronic device has the faulty alarm channel, and the elements in the above-mentioned fault matrix correspond one-to-one to the unique identifier of the above-mentioned electronic device; and the above-mentioned alarm channels of each of the above-mentioned electronic devices are troubleshooted according to the above-mentioned fault matrix. This application collects the alarm information issued during the relay protection test, analyzes the alarm relationship between each device during the relay protection test, constructs an alarm channel relationship matrix, and uses the matrix to calculate the alarm channels that may have faults. When troubleshooting, the staff only needs to check the alarm channels that may have faults one by one, without having to check all channels one by one, which improves the work efficiency of alarm channel fault troubleshooting and solves the problem of low work efficiency caused by the need to check the fault alarm channels one by one during the substation relay protection test in the prior art.

[0043] In order to more accurately determine the electronic device involved in the current alarm information, in an optional embodiment, the current alarm information issued by the current relay protection test is obtained, and the electronic device involved in the current alarm information is determined. The method includes:

[0044] Step S2011: Obtain historical alarm information issued by the relay protection test of the substation, and classify the historical alarm information according to fault type to obtain a classification result. The classification result includes the fault type corresponding to each historical alarm information and the electronic equipment involved in each fault type. The fault types include sampling fault type, tripping fault type, communication fault type, and main body fault type.

[0045] Specifically, before obtaining the alarm information issued by the current relay protection test and determining the electronic equipment involved in the current alarm information, the historical alarm information of the substation relay protection test is first obtained and classified according to the fault type. The classification results include the fault type corresponding to each historical alarm information, such as sampling fault type, tripping fault type, communication fault type and main body fault type. By classifying and analyzing the historical alarm information, we can better understand the electronic equipment corresponding to different types of faults, which is helpful to identify the electronic equipment involved in the current alarm information and the possible causes of the fault. Such a classification and organization process can improve the accuracy and efficiency of fault diagnosis, and provide guidance and reference for subsequent fault handling and maintenance work.

[0046] It should be noted that historical alarm information is classified according to fault type, including:

[0047] Sampling faults, namely, faults and anomalies that occur in all devices related to the SV message sampling communication circuit. These faults or anomalies directly affect the reception and release of SV messages. The sampling faults mainly include protection devices, merging units, network analyzers, and intelligent terminals.

[0048] Tripping faults refer to faults and anomalies of all devices related to the GOOSE message sampling and communication circuit. These faults or anomalies directly affect the reception and release of GOOSE messages. The devices included in the tripping fault category include protection devices, merging units, intelligent terminals, and circuit breakers.

[0049] Communication failures: failures or anomalies in the SV and GOOSE message communication links and the input and output ports of related equipment. These failures or anomalies usually affect the reception and transmission of SV and GOOSE messages. Communication failures mainly affect protection devices, merging units, intelligent terminals, and optical fiber links.

[0050] The main body failure type refers to the failure of the secondary equipment itself, such as equipment memory errors, equipment power failures, and equipment CPU plug-in abnormalities. Any failure that only involves the equipment itself can be considered as a main body failure type. Therefore, when the fault type is a main body failure type, maintenance personnel are required to inspect the internal electronic components of all electronic equipment involved in the fault one by one.

[0051] Step S2012: obtaining the current alarm information issued by the current relay protection test, and determining the fault type corresponding to the current alarm information and the electronic device involved in the current alarm information according to the classification result.

[0052] Specifically, based on the above classification results of historical fault alarm information, the current alarm information is compared with the fault type in the classification results to determine the fault type to which the current alarm information belongs, and the electronic equipment involved in the current alarm information is determined based on the electronic equipment involved in the fault type, so that potential problems can be dealt with in a timely manner by analyzing the communication relationship between electronic devices to ensure the normal operation of the system.

[0053] In order to establish a better association relationship between the electronic devices, in an optional embodiment, the alarm channels between the electronic devices are obtained, and an alarm channel matrix between the electronic devices is constructed based on the alarm channels. The method includes:

[0054] Step S2021: constructing a network topology diagram of the alarm channels of the electronic devices according to the alarm channels between the electronic devices, wherein the network topology diagram of the alarm channels includes the alarm channels between the electronic devices;

[0055] Specifically, based on the alarm channels between various electronic devices, a network topology diagram of the alarm channels between these electronic devices is drawn. This topology diagram shows the communication paths and connection relationships between the devices, which helps to intuitively understand the information transmission methods and communication conditions between devices. By constructing an alarm channel network topology diagram, we can fully understand the communication structure and correlation between devices, which is convenient for subsequent timely discovery and resolution of communication problems.

[0056] In a specific embodiment, during the relay protection test, an alarm message is received from the protection device, which indicates that the SV sampling link of the protection device is interrupted. The other devices do not issue an alarm message. According to the above classification results, it can be determined that the fault type of the current alarm message is a sampling fault type. The electronic devices involved are the protection device, the merging unit, the network analyzer, and the intelligent terminal. Figure 3 As shown, based on the communication relationship between the above-mentioned electronic devices, that is, the alarm channels between them, a network topology diagram of the alarm channels between the above-mentioned electronic devices is drawn.

[0057] Step S2022: construct an alarm channel matrix between the electronic devices based on the alarm channel network topology diagram. The alarm channel matrix is Among them, b(a i ,a j ) indicates that the above-mentioned electronic devices corresponding to the above-mentioned alarm information have an identifier of a i The above electronic device and identifier is a j Whether there is an alarm channel between the above-mentioned electronic devices, 1≤i≤n, 1≤j≤n, n is the number of the above-mentioned electronic devices involved in the above-mentioned current alarm information.

[0058] Specifically, based on the constructed alarm channel network topology diagram, an alarm channel matrix is ​​generated between each electronic device. The matrix is ​​used to indicate whether there is an alarm channel between each pair of electronic devices, so as to better analyze and manage the communication path between devices. By establishing the alarm channel matrix, maintenance personnel can have a clearer understanding of the communication status between electronic devices and determine whether there is an alarm channel between two devices.

[0059] It is understandable that if electronic equipment a i For electronic equipment j The information of b(a i ,a j ) is 1, otherwise, b(a i ,a j ) has a value of 0.

[0060] In order to construct an alarm data matrix, in an optional embodiment, the method includes determining the faulty electronic device among the electronic devices based on the alarm information, and constructing the alarm data matrix based on the normal electronic devices and the faulty electronic devices.

[0061] Step S2031, determining the electronic device that has failed among the electronic devices based on the alarm information;

[0062] Specifically, the current alarm information issued during the relay protection test is collected, the current alarm information is analyzed, and based on the alarm information, it is confirmed which electronic equipment has failed, so that necessary measures can be taken to repair the failure and ensure the normal operation of the system.

[0063] Step S2032: construct an alarm data matrix based on the normal electronic equipment and the faulty electronic equipment. The alarm data matrix is ​​C = [c1 c2 c3 ... c n ] T , where c n Indicates that the identifier of each of the above electronic devices corresponding to the above warning information is a n Check whether the above electronic equipment has malfunctioned.

[0064] Specifically, electronic equipment that has not failed and electronic equipment that has failed are determined based on the current alarm information, and an alarm data matrix is ​​established based on the equipment that has not failed and the equipment that has failed. In this matrix, each element indicates whether the corresponding equipment has failed. This helps to quickly identify faulty electronic equipment and improve the work efficiency of maintenance personnel.

[0065] Understandably, c n Indicates the nth electronic device among the electronic devices corresponding to the above-mentioned alarm information, if c nIf the value of c is 1, it means that the nth electronic device among the electronic devices corresponding to the alarm information has failed. On the contrary, if c n If the value of is 0, it indicates that the nth electronic device among the electronic devices corresponding to the alarm information has not failed, and T indicates that the matrix C is a transposed matrix.

[0066] In order to determine whether the electronic device has a faulty alarm channel, in an optional embodiment, the product of the alarm channel matrix and the alarm data matrix is ​​calculated to obtain a fault matrix. The method includes:

[0067] Step S301: The fault matrix is ​​calculated by the preset formula P=B·C, where B is the alarm channel matrix, C is the alarm data matrix, and the fault matrix is ​​P=[p1 p2 p3 … p n ] T , p n Indicates whether the corresponding electronic device has the above-mentioned alarm channel of failure.

[0068] Specifically, a fault matrix is ​​calculated using a preset formula. The fault matrix is ​​used to indicate whether each electronic device has a fault alarm channel, providing a more intuitive way to identify which electronic devices have a fault alarm channel.

[0069] It is understandable that if p n =i (i≥0), it means that the corresponding electronic device has i fault alarm channels, and T means that the matrix P is a transposed matrix.

[0070] In order to determine the specific location of the fault alarm channel and troubleshoot it, in an optional embodiment, the fault is troubleshooted on the alarm channel of each of the electronic devices according to the fault matrix. The method includes:

[0071] Step S401, determining each of the electronic devices having a fault in the alarm data matrix as a first electronic device, and determining each of the electronic devices having a faulty alarm channel in the fault matrix as a second electronic device;

[0072] Specifically, each electronic device confirmed to have failed in the alarm data matrix is ​​regarded as the first electronic device, and the electronic device with a failed alarm channel in the fault matrix is ​​regarded as the second electronic device. Such classification helps to subsequently determine the specific location of the specific alarm channel that may have failed.

[0073] Step S402: determining that the alarm channel between the first electronic device and the second electronic device is a possible fault alarm channel;

[0074] Specifically, the alarm channel between the first type of device and the second type of device is regarded as an alarm channel that may have a fault. By determining the alarm channel that may have a fault, troubleshooting and repair work of the fault alarm channel can be carried out in a targeted manner, the speed of maintenance personnel in maintenance is accelerated, and work efficiency is improved.

[0075] In step S403, each of the above possible fault alarm channels is checked to determine the actual fault alarm channel.

[0076] Specifically, by carefully analyzing the fault matrix and the fault electronic device in the alarm data matrix, it is determined which electronic devices between the alarm channels may have problems. Each electronic device of the alarm channel that may have a fault is checked one by one to confirm whether there is a fault or an abnormal situation, until the fault alarm channel that causes the specific fault reason is checked out, the specific fault position and reason are determined, and the fault alarm channel is repaired until no alarm information is sent out, and the communication between the electronic devices is ensured to be stable transmission.

[0077] Figure 4 An alarm channel interruption alarm mechanism diagram of the above-mentioned alarm channel fault checking method of the relay protection test is shown, as shown in Figure 4 For the information flow propagating in the optical fiber, the party that publishes the information is called the sender, and the party that subscribes to the information is called the receiver. In the case of normal operation of the sending and receiving process, there is always information transmission. When the alarm channel is interrupted due to unknown reasons, the party that subscribes to the information cannot receive the subscribed information, and the receiver will automatically call the channel self-checking program to perform channel self-checking, and then light the corresponding abnormal operation lamp of the device and transmit the alarm information of the channel interruption to the remote monitoring system.

[0078] In another embodiment, the above embodiment is described taking the 220kV line interval of a certain 220kV intelligent station as an example.

[0079] During the relay protection test, an alarm information is received from the protection device, and the content is that the SV sampling link of the protection device is interrupted, and the remaining devices do not send alarm information.

[0080] Based on the above alarm information sent by the protection device and combined with the above classification result, it is determined that the alarm information sent by the protection device belongs to the sampling fault type, and the electronic devices involved are the protection device, the merging unit, the network analyzer and the intelligent terminal.

[0082] Construct an alarm channel matrix based on the above network topology diagram

[0083] The faulty electronic device is determined based on the alarm information. Since only the protection device issues the alarm information (the SV sampling link of the protection device is interrupted), the protection device is the faulty electronic device.

[0085] According to the preset formula, the fault matrix P = B·C = [0 0 1 1] T ,It is known that there are alarm fault channels in the ,network analyzer and the intelligent terminal.

[0086] According to the electronic devices with faulty alarm channels in the fault matrix and the faulty electronic devices in the alarm data matrix, it can be determined that there may be faults in the alarm channels between the protection device and the network analyzer, and between the protection device and the intelligent terminal.

[0087] Check the two alarm channels that may have faults, determine the specific faulty alarm channel and perform repairs.

[0088] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0091] Figure 5This is a structural block diagram of an alarm channel fault troubleshooting device for relay protection testing according to an embodiment of the present application. Figure 5 As shown, the device includes:

[0092] The first determining unit 10 is configured to obtain current alarm information issued by the current relay protection test and determine the electronic device involved in the current alarm information;

[0093] Specifically, during the relay protection test, if a device fails and issues an alarm message, the alarm message issued by the system is collected, and based on the alarm message issued by the current relay protection test, the electronic device that may be related to the alarm message is analyzed, so as to promptly deal with potential problems by analyzing whether there is a fault in the electronic device to ensure the normal operation of the system.

[0097] Specifically, based on the alarm information issued by the current relay protection test, determine which devices have faults, and establish a matrix based on normal electronic equipment and faulty electronic equipment. The matrix is ​​defined as an alarm data matrix to indicate whether each device has a fault. Each electronic device corresponds to a unique identifier, and each element in the matrix corresponds one-to-one with the unique identifier of the electronic device. This allows for a clearer understanding of the specific information and fault status of each device. By establishing an alarm data matrix, we can more effectively identify and locate equipment faults, thereby speeding up subsequent troubleshooting and repair.

[0098] A first calculation unit 40 is configured to calculate the product of the alarm channel matrix and the alarm data matrix to obtain a fault matrix, wherein the elements of the fault matrix are used to indicate whether the corresponding electronic device has the faulty alarm channel, and the elements of the fault matrix correspond one-to-one to the unique identifier of the electronic device;

[0099] Specifically, the alarm channel matrix and the alarm data matrix are multiplied to obtain a fault matrix. The elements in the fault matrix indicate whether the corresponding electronic device has a fault alarm channel. By calculating the fault matrix, we can more accurately identify which electronic devices have fault alarm channels and need attention and processing, and take measures to repair the problems. In addition, each element of the fault matrix corresponds to the unique identifier of the electronic device, so that the specific information and fault status of each device can be more clearly understood.

[0100] The first control unit 50 is configured to perform fault detection on the alarm channel of each of the electronic devices according to the fault matrix.

[0101] Specifically, the fault matrix is ​​used to troubleshoot each electronic device with a faulty alarm channel. During the troubleshooting process, it is necessary to analyze the faulty electronic devices in the fault matrix and the alarm data matrix, determine which electronic devices may have faulty alarm channels, and then check each electronic device with a potentially faulty alarm channel to confirm whether there is a fault or abnormality. This process continues until the specific location and cause of the faulty alarm channel are determined. The faulty alarm channel is then repaired to ensure normal communication between the electronic devices until the alarm information is no longer issued.

[0102] Through this embodiment, the first determination unit is used to obtain the current alarm information issued by the current relay protection test, and determine the electronic equipment involved in the current alarm information; the second determination unit is used to obtain the alarm channels between each of the above electronic devices, and construct an alarm channel matrix between each of the above electronic devices based on the above alarm channels.

An alarm data matrix is ​​constructed with the above-mentioned electronic devices that have failed, and the elements in the above-mentioned alarm data matrix are respectively used to indicate whether each of the above-mentioned electronic devices has failed, and the elements in the above-mentioned alarm data matrix correspond one-to-one with the unique identifier of the above-mentioned electronic device; a first calculation unit is used to calculate the product of the above-mentioned alarm channel matrix and the above-mentioned alarm data matrix to obtain a fault matrix, and the elements in the above-mentioned fault matrix are used to characterize whether the corresponding above-mentioned electronic device has the above-mentioned fault alarm channel, and the elements in the above-mentioned fault matrix correspond one-to-one with the unique identifier of the above-mentioned electronic device; a first control unit is used to troubleshoot the above-mentioned alarm channels of each of the above-mentioned electronic devices according to the above-mentioned fault matrix. The present application collects the alarm information issued during the relay protection test, analyzes the alarm relationship between each device during the relay protection test, constructs an alarm channel relationship matrix, and uses the matrix to calculate the alarm channels that may have faults. During troubleshooting, the staff only needs to check the alarm channels that may have faults one by one, without having to check all channels one by one, thereby improving the efficiency of alarm channel troubleshooting and solving the problem of low work efficiency caused by the need to check the fault alarm channels one by one during the substation relay protection test in the prior art.

[0103] In order to more accurately determine the electronic device involved in the current alarm information, in an optional embodiment, the current alarm information issued by the current relay protection test is obtained, and the electronic device involved in the current alarm information is determined. The first determining unit includes:

[0104] A first determination module obtains historical alarm information issued by the relay protection test of the substation, and classifies the historical alarm information according to fault type to obtain a classification result, wherein the classification result includes the fault type corresponding to each historical alarm information and the electronic equipment involved in each fault type. The fault types include sampling fault type, tripping fault type, communication fault type, and main body fault type;

[0105] Specifically, before obtaining the alarm information issued by the current relay protection test and determining the electronic equipment involved in the current alarm information, the historical alarm information of the substation relay protection test is first obtained and classified according to the fault type. The classification results include the fault type corresponding to each historical alarm information, such as sampling fault type, tripping fault type, communication fault type and main body fault type. By classifying and analyzing the historical alarm information, we can better understand the electronic equipment corresponding to different types of faults, which is helpful to identify the electronic equipment involved in the current alarm information and the possible causes of the fault. Such a classification and organization process can improve the accuracy and efficiency of fault diagnosis, and provide guidance and reference for subsequent fault handling and maintenance work.

[0106] It should be noted that historical alarm information is classified according to fault type, including:

[0107] Sampling faults, namely, faults and anomalies that occur in all devices related to the SV message sampling communication circuit. These faults or anomalies directly affect the reception and release of SV messages. The sampling faults mainly include protection devices, merging units, network analyzers, and intelligent terminals.

[0108] Tripping faults refer to faults and anomalies of all devices related to the GOOSE message sampling and communication circuit. These faults or anomalies directly affect the reception and release of GOOSE messages. The devices included in the tripping fault category include protection devices, merging units, intelligent terminals, and circuit breakers.

[0109] Communication failures: failures or anomalies in the SV and GOOSE message communication links and the input and output ports of related equipment. These failures or anomalies usually affect the reception and transmission of SV and GOOSE messages. Communication failures mainly affect protection devices, merging units, intelligent terminals, and optical fiber links.

[0110] The main body failure type refers to the failure of the secondary equipment itself, such as equipment memory errors, equipment power failures, and equipment CPU plug-in abnormalities. Any failure that only involves the equipment itself can be considered as a main body failure type. Therefore, when the fault type is a main body failure type, maintenance personnel are required to inspect the internal electronic components of all electronic equipment involved in the fault one by one.

[0111] The second determination module obtains the current alarm information issued by the current relay protection test, and determines the fault type corresponding to the current alarm information and the electronic device involved in the current alarm information according to the classification result.

[0112] Specifically, according to the classification result of the historical fault alarm information, the current alarm information is compared with the fault types in the classification result, the fault type to which the current alarm information belongs is judged, and the electronic equipment involved in the fault type is determined, so that the potential problem can be processed in time by analyzing the communication relationship between the electronic equipment in the future, and the normal operation of the system is ensured.

[0113] In order to establish a better association relationship between each electronic equipment, in an optional embodiment, the alarm channels between each of the above electronic equipment are obtained, and an alarm channel matrix between each of the above electronic equipment is constructed based on the alarm channels. The second determination unit comprises:

[0114] A third determination module constructs an alarm channel network topology graph of the above electronic equipment according to the alarm channels between each of the above electronic equipment, and the alarm channel network topology graph contains the alarm channels between each of the above electronic equipment.

[0115] Specifically, according to the alarm channels between each electronic equipment, an alarm channel network topology graph between these electronic equipment is drawn, which shows the communication path and connection relationship between each device, which helps to intuitively understand the information transmission mode and communication situation between devices. By constructing the alarm channel network topology graph, the communication structure and association between devices can be comprehensively understood, which facilitates timely discovery and solution of communication problems.

[0116] In a specific embodiment, during the relay protection test, the alarm information issued by the protection device is received, the content of which is that the sampling link of the protection device SV is interrupted, and the remaining devices do not issue alarm information. According to the classification result, it can be determined that the fault type to which the current alarm information belongs is the sampling fault class, and the electronic equipment involved includes the protection device, the merging unit, the network analyzer and the intelligent terminal, as shown in Figure 3 According to the communication relationship between each of the above electronic equipment, i.e. the alarm channel between them, an alarm channel network topology graph between each of the above electronic equipment is drawn.

[0117] A fourth determination module constructs an alarm channel matrix between each of the above electronic equipment based on the alarm channel network topology graph, and the alarm channel matrix is Wherein, b(a i ,a j ) represents whether there is an alarm channel between the electronic equipment with identifier a i and the electronic equipment with identifier a j corresponding to the above alarm information, 1≤i≤n, 1≤j≤n, n is the number of the above electronic equipment involved in the current alarm information.

[0118] Specifically, based on the constructed alarm channel network topology diagram, an alarm channel matrix is ​​generated between each electronic device. The matrix is ​​used to indicate whether there is an alarm channel between each pair of electronic devices, so as to better analyze and manage the communication path between devices. By establishing the alarm channel matrix, maintenance personnel can have a clearer understanding of the communication status between electronic devices and determine whether there is an alarm channel between two devices.

[0119] It is understandable that if electronic equipment a i For electronic equipment j The information of b(a i ,a j ) is 1, otherwise, b(a i ,a j ) has a value of 0.

[0120] In order to construct the alarm data matrix, in an optional embodiment, the faulty electronic device among the electronic devices is determined based on the alarm information, and the alarm data matrix is ​​constructed based on the normal electronic devices and the faulty electronic devices. The third determining unit includes:

[0121] a fifth determining module, for determining a faulty electronic device among the electronic devices based on the alarm information;

[0122] Specifically, the current alarm information issued during the relay protection test is collected, the current alarm information is analyzed, and based on the alarm information, it is confirmed which electronic equipment has failed, so that necessary measures can be taken to repair the failure and ensure the normal operation of the system.

[0123] The sixth determining module constructs an alarm data matrix based on the normal electronic equipment and the faulty electronic equipment. The alarm data matrix is ​​C = [c1 c2 c3 ... c n ] T , where c n Indicates that the identifier of each of the above electronic devices corresponding to the above warning information is a n Check whether the above electronic equipment has malfunctioned.

[0124] Specifically, electronic equipment that has not failed and electronic equipment that has failed are determined based on the current alarm information, and an alarm data matrix is ​​established based on the equipment that has not failed and the equipment that has failed. In this matrix, each element indicates whether the corresponding equipment has failed. This helps to quickly identify faulty electronic equipment and improve the work efficiency of maintenance personnel.

[0125] Understandably, c n Indicates the nth electronic device among the electronic devices corresponding to the above-mentioned alarm information, if c nIf the value of c is 1, it means that the nth electronic device among the electronic devices corresponding to the alarm information has failed. On the contrary, if c n If the value of is 0, it indicates that the nth electronic device among the electronic devices corresponding to the alarm information has not failed, and T indicates that the matrix C is a transposed matrix.

[0126] In order to determine whether the electronic device has a faulty alarm channel, in an optional embodiment, the product of the alarm channel matrix and the alarm data matrix is ​​calculated to obtain a fault matrix. The first calculation unit includes:

[0127] The first calculation module calculates the fault matrix by the preset formula P=B·C, where B is the alarm channel matrix, C is the alarm data matrix, and the fault matrix is ​​P=[p1 p2 p3…p n ] T , p n Indicates whether the corresponding electronic device has the above-mentioned alarm channel of failure.

[0128] Specifically, a fault matrix is ​​calculated using a preset formula. The fault matrix is ​​used to indicate whether each electronic device has a fault alarm channel, providing a more intuitive way to identify which electronic devices have a fault alarm channel.

[0129] It is understandable that if p n =i (i≥0), it means that the corresponding electronic device has i fault alarm channels, and T means that the matrix P is a transposed matrix.

[0130] In order to determine the specific location of the fault alarm channel and troubleshoot it, in an optional embodiment, the fault is checked for the alarm channel of each of the electronic devices according to the fault matrix, and the first control unit includes:

[0131] a first control module, determining each of the electronic devices having a fault in the alarm data matrix as a first electronic device, and determining each of the electronic devices having a faulty alarm channel in the fault matrix as a second electronic device;

[0132] Specifically, each electronic device confirmed to have failed in the alarm data matrix is ​​regarded as the first electronic device, and the electronic device with a failed alarm channel in the fault matrix is ​​regarded as the second electronic device. Such classification helps to subsequently determine the specific location of the specific alarm channel that may have failed.

[0133] The second control module determines that the alarm channel between the first electronic device and the second electronic device is a possible fault alarm channel;

[0134] Specifically, the alarm channel between the first type of equipment and the second type of equipment is regarded as an alarm channel that may have a fault. By determining the alarm channel that may have a fault, the fault alarm channel can be checked and repaired in a targeted manner, which speeds up the maintenance speed of maintenance personnel and improves work efficiency.

[0135] The third control module checks each of the possible fault alarm channels to determine the alarm channel with actual fault.

[0136] Specifically, by carefully analyzing the faulty electronic devices in the fault matrix and the alarm data matrix, determine which electronic devices may have problems with the alarm channels, check each electronic device with a possible faulty alarm channel one by one, and confirm whether there is a fault or abnormality, until the faulty alarm channel that causes the specific fault cause is found, the specific fault location and cause are determined, and the faulty alarm channel is repaired until the alarm information is no longer issued, ensuring that the communication between electronic devices maintains stable transmission.

[0137] The alarm channel fault troubleshooting device for relay protection testing includes a processor and a memory. The first determination unit, second determination unit, third determination unit, first calculation unit, first control unit, etc. are all stored as program units in the memory. The processor executes the program units stored in the memory to implement corresponding functions. The above modules are all located in the same processor; alternatively, the above modules can be located in different processors in any combination.

[0138] The processor contains a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be configured, and the efficiency of troubleshooting alarm channels can be improved by adjusting kernel parameters.
