Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to an exception handling method, apparatus, computer device, and storage medium. Background Technology

[0002] Currently, ultra-high voltage direct current (UHVDC) transmission projects mainly adopt a dual-valve-group series connection method. This method inevitably involves the online connection / deactivation of individual valve groups, which relies on the corresponding control system to control the opening and closing of the bypass circuit breaker. This control logic uses the current at the bypass circuit breaker's measuring point. When the measuring point current is abnormal, the corresponding control system will be unable to properly execute the online connection / deactivation operation to the bypass circuit breaker.

[0003] However, current methods for handling UHVDC transmission faults caused by abnormal current at bypass circuit breaker measuring points simply categorize all faults as emergency faults or minor faults, which reduces the reliability of DC transmission system operation. Summary of the Invention

[0004] Therefore, it is necessary to provide an anomaly handling method, device, computer equipment, and storage medium that can effectively improve the operational reliability of DC transmission systems in response to the aforementioned technical problems.

[0005] Firstly, this application provides an exception handling method, which includes:

[0006] Based on the current operating status of the valve group, determine the validity of the valve group operating command sent by the master-slave control system to the bypass circuit breaker; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0007] Determine the results based on validity and determine the exception handling logic;

[0008] An exception handling logic is used to handle exceptions in the master-slave control system.

[0009] In one embodiment, based on the validity determination result, the exception handling logic is determined, including:

[0010] Based on the validity determination results and the order in which the master-slave control system detects abnormal current at the bypass circuit breaker measurement point, the abnormality handling logic is determined.

[0011] In one embodiment, based on the validity determination result and the order in which the master-slave control system detects abnormal current at the bypass circuit breaker's measuring point, the abnormality handling logic is determined, including:

[0012] If the validity determination result is invalid, and the main control system first detects the abnormal current at the measuring point of the bypass circuit breaker, then the abnormal handling logic is determined to be the first abnormal handling logic.

[0013] If the validity determination result is invalid, and the abnormal current at the measuring point is detected first from the control system, then the abnormality handling logic is determined to be the second abnormality handling logic.

[0014] If the validity determination result is valid, and the main control system detects the abnormal current at the measuring point first, then the abnormality handling logic is determined to be the third abnormality handling logic.

[0015] If the validity determination result is valid, and the abnormal current at the measuring point is detected first from the control system, then the abnormality handling logic is determined to be the fourth abnormality handling logic.

[0016] In one embodiment, if the exception handling logic is a first exception handling logic or a third exception handling logic, then the exception handling logic is used to perform exception handling on the master-slave control system, including:

[0017] Update the operating status of the main control system to a fault state and prohibit the main control system from sending valve group operation commands to the bypass circuit breaker.

[0018] Perform master-slave switching on the master-slave control system;

[0019] Based on the detection of abnormal current at the measuring point by the switched main control system, abnormal handling is performed on the switched main control system.

[0020] The fault state corresponding to the first fault handling logic is lower than the fault state corresponding to the third fault handling logic.

[0021] In one embodiment, if the exception handling logic is a second exception handling logic or a fourth exception handling logic, then the exception handling logic is used to perform exception handling on the master-slave control system, including:

[0022] The operating status of the control system will be updated to a fault status, and the operation of sending valve group operation commands to the bypass circuit breaker from the control system will be prohibited.

[0023] Based on the main control system's detection of abnormal current at the measuring point, abnormal handling is performed on the main control system.

[0024] The fault state corresponding to the second exception handling logic is lower than the fault state corresponding to the fourth exception handling logic.

[0025] In one embodiment, based on the main control system's detection of abnormal current at the measuring point, abnormal handling is performed on the main control system, including:

[0026] If the main control system detects an abnormal current at the measuring point, it will update the operating status of the main control system to a fault state and prohibit the main control system from sending valve group operation commands to the bypass circuit breaker.

[0027] If the main control system does not detect any abnormal current at the measuring point, it will then send a valve group operation command to the bypass circuit breaker.

[0028] Secondly, this application also provides an anomaly handling apparatus, the apparatus comprising:

[0029] The validity determination module is used to determine the validity of the valve group operation command sent by the master-slave control system to the bypass circuit breaker based on the current operating state of the valve group; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0030] The logic determination module is used to determine the result based on validity and to determine the exception handling logic;

[0031] The exception handling module is used to handle exceptions in the master-slave control system using exception handling logic.

[0032] Thirdly, this application also provides a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0033] Based on the current operating status of the valve group, determine the validity of the valve group operating command sent by the master-slave control system to the bypass circuit breaker; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0034] Determine the results based on validity and determine the exception handling logic;

[0035] An exception handling logic is used to handle exceptions in the master-slave control system.

[0036] Fourthly, this application also provides a computer-readable storage medium having a computer program stored thereon, the computer program performing the following steps when executed by a processor:

[0037] Based on the current operating status of the valve group, determine the validity of the valve group operating command sent by the master-slave control system to the bypass circuit breaker; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0038] Determine the results based on validity and determine the exception handling logic;

[0039] An exception handling logic is used to handle exceptions in the master-slave control system.

[0040] Fifthly, this application also provides a computer program product, which includes a computer program that, when executed by a processor, performs the following steps:

[0041] Based on the current operating status of the valve group, determine the validity of the valve group operating command sent by the master-slave control system to the bypass circuit breaker; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0042] Determine the results based on validity and determine the exception handling logic;

[0043] An exception handling logic is used to handle exceptions in the master-slave control system.

[0044] The aforementioned anomaly handling method, apparatus, computer equipment, and storage medium, by determining the validity of valve group operating commands sent from the master-slave control system to the bypass circuit breaker based on the current operating state of the valve group, can then employ anomaly handling logic determined based on the validity determination result to handle anomalies in the master-slave control system. This scheme, by determining the anomaly handling logic for the master-slave control system based on the specific operating conditions within the DC transmission system, namely the operating state of the valve group, enables more rational handling of the master-slave control system, thereby effectively improving the reliability of the DC transmission system operation.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] The exception handling method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. The data storage system can store data that server 104 needs to process, such as various exception handling logics in scenarios where the current at the bypass circuit breaker of the control valve group is abnormal. The data storage system can be integrated on server 104 or placed on the cloud or other network servers. The exception handling method provided in this application can be applied to server 104, terminal 102, or through interaction between terminal 102 and server 104. For example, server 104 determines the validity of the valve group operating command sent by the master-slave control system to the bypass circuit breaker based on the current operating state of the valve group, determines the exception handling logic based on the validity, and then uses the exception handling logic to perform exception handling on the master-slave control system. Furthermore, the exception handling result can be displayed through terminal 102. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, etc. Server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.

[0055] In one embodiment, such as Figure 2 As shown, an anomaly handling method is provided. This embodiment relates to how to handle the anomaly in the master-slave control system corresponding to the valve group when the measuring current at the bypass circuit breaker of the control valve group is abnormal. This embodiment applies this method to... Figure 1 Taking server 104 as an example, the following steps are included:

[0056] S201, based on the current operating status of the valve group, determine the validity of the valve group operating command sent by the master-slave control system corresponding to the valve group to the bypass circuit breaker.

[0057] Here, valve group refers to the combination of valves that control the power transmission process during power transmission; each valve group corresponds to a master-slave control system, which includes a master control system and at least one slave control system. This application uses a slave control system as an example for illustration.

[0058] Optional, such as Figure 3As shown, one valve group can correspond to one bypass circuit breaker. A bypass circuit breaker refers to a circuit breaker with fast closing capability. For example, in this embodiment, the bypass circuit breaker is used to control the switching of the valve group's operating state. Specifically, under normal valve group operation, the master / slave controller corresponding to the valve group sends a valve group operating command to the bypass circuit breaker. The bypass circuit breaker responds to the valve group operating command to switch the valve group's operating state.

[0059] The valve group operation command can be either a valve group engagement command or a valve group disengagement command. An engagement command is a command to engage the valve group under DC power transmission operation; a disengagement command is a command to disengage the valve group from DC power transmission operation.

[0060] Optionally, the server can store the valve group working status corresponding to the pre-set valve group working instructions. By comparing the current working status of the valve group with the pre-set valve group working status, the validity of the valve group working instructions sent by the master-slave control system to the bypass circuit breaker can be determined.

[0061] Furthermore, after the control system sends a valve group operation command to the bypass circuit breaker, if the current operating state of the valve group is the same as the preset valve group operating state, then the valve group operation command sent by the master-slave control system to the bypass circuit breaker is determined to be valid; if the current operating state of the valve group is different from the preset valve group operating state, then the valve group operation command sent by the master-slave control system to the bypass circuit breaker is determined to be invalid.

[0062] S202, determine the result based on validity and determine the exception handling logic.

[0063] Among them, the abnormal handling logic refers to the way to handle abnormalities in the master-slave control system when there is a fault in the DC transmission system (specifically, abnormal current at the measuring point of the bypass circuit breaker).

[0064] Optionally, this embodiment can be configured with multiple different exception handling logics. Therefore, if the valve group operation command sent by the master-slave control system to the bypass circuit breaker is invalid, this abnormal situation can be referred to as a level one fault state, and the corresponding exception handling logic (specifically including a first exception handling logic and a second exception handling logic) is stored in the server.

[0065] Furthermore, if the valve group operation command sent by the control system to the bypass circuit breaker is valid, this abnormal situation can be referred to as a level two fault state, and the corresponding abnormal handling logic (which may include third and fourth abnormal handling logic) is stored in the server.

[0066] Furthermore, a Level 1 fault condition is considered inferior to a Level 2 fault condition. A Level 1 fault condition corresponds to a minor fault, while a Level 2 fault condition corresponds to an emergency fault.

[0067] S203 employs exception handling logic to handle exceptions in the master-slave control system.

[0068] Specifically, after determining the exception handling logic, exception handling can be performed on the master-slave control system based on the determined exception handling logic. For example, taking a level one fault state as an example, the operating state of both the master and slave control systems can be set to a minor fault state, and the operation of sending valve group working commands to the bypass circuit breaker can be prohibited.

[0069] The aforementioned anomaly handling method, by determining the validity of the valve group's operating commands sent from the master-slave control system to the bypass circuit breaker based on the valve group's current operating state, can then employ anomaly handling logic determined based on the validity determination result to handle anomalies in the master-slave control system. This scheme, by determining the anomaly handling logic for the master-slave control system based on the specific operating conditions within the DC transmission system—namely, the valve group's operating state—enables more rational handling of the master-slave control system, thereby effectively improving the reliability of the DC transmission system's operation.

[0070] Understandably, each valve group has a point near its bypass circuit breaker for real-time current measurement to check for abnormalities. Due to varying fault conditions, the order in which the master and slave control systems detect abnormal current at the bypass circuit breaker's measurement point also differs. To analyze the fault conditions of the DC transmission system in more detail, the anomaly handling logic can be determined based on the validity determination results and the order in which the master and slave control systems detect abnormal current at the bypass circuit breaker's measurement point.

[0071] Optionally, based on the validity of the results and the order in which the master-slave control system detects abnormal current at the bypass circuit breaker's measuring point, the abnormal situations can be classified into different types, and corresponding abnormal handling logic can be determined for each type of abnormal situation.

[0072] For example, if the validity determination result is invalid, and the main control system first detects an abnormality in the measuring point current of the bypass circuit breaker, then the abnormality handling logic is determined to be the first abnormality handling logic.

[0073] If the validity determination result is invalid, and the control system detects an abnormal current at the measuring point first, then the abnormality handling logic is determined to be the second abnormality handling logic.

[0074] If the validity determination result is valid, and the main control system detects the abnormal current at the measuring point first, then the abnormality handling logic is determined to be the third abnormality handling logic.

[0075] If the validity determination result is valid, and the abnormal current at the measuring point is detected first from the control system, then the abnormality handling logic is determined to be the fourth abnormality handling logic.

[0076] It should be noted that this embodiment combines the validity determination results with the internal operating conditions of the DC transmission system, namely the order in which the master and slave control systems detect abnormal current at the bypass circuit breaker measurement point, and introduces a variety of different abnormality handling logics to further improve the reliability of the DC transmission system operation.

[0077] Optionally, different exception handling logics may handle exceptions in different ways. Based on the above embodiments, S203 will be further explained in detail.

[0078] For example, combining Figure 4 As shown, when the exception handling logic is either the first exception handling logic or the third exception handling logic, the exception handling process can specifically be as follows:

[0079] S401 updates the operating status of the main control system to a fault state and prohibits the main control system from sending valve group operation commands to the bypass circuit breaker.

[0080] It should be noted that, under normal circumstances, the master-slave control system operates in a fault-free state. Optionally, if the exception handling logic is set to the first exception handling logic, the master control system can be updated from a fault-free state to a fault state (such as a minor fault state), and the master control system is prohibited from sending valve group operation commands to the bypass circuit breaker.

[0081] Furthermore, when the exception handling logic is the third exception handling logic, the main control system can be updated from a fault-free operating state to a fault state (such as an emergency fault state), and the main control system is prohibited from sending valve group working instructions to the bypass circuit breaker.

[0082] Optionally, in this embodiment, the fault state corresponding to the first fault handling logic is lower than the fault state corresponding to the third fault handling logic. It is understood that the main control system corresponding to the first fault handling logic remains usable under minor fault conditions, while the main control system corresponding to the third fault handling logic is unusable under emergency fault conditions.

[0083] S402 performs a master-slave switch for the master-slave control system.

[0084] Optionally, when the exception handling logic is the first exception handling logic, after the main control system is set to a minor fault state, since the host controlled by the main system is still available in the minor fault state, a delay can be used to ensure a smooth switch between the master and slave control systems. For example, the master control system can be delayed (generally 1 second) to become a slave control system. Correspondingly, after the master control system is switched to a slave control system, the original slave control system is switched to the master control system.

[0085] Furthermore, when the exception handling logic is the third exception handling logic, after the main control system is set to an emergency fault state, since the host of the main control system is unavailable in the emergency fault state, it is necessary to switch to the slave control system instantly to ensure that the DC transmission system can operate smoothly. For example, the main control system can be immediately downgraded to the slave control system, and the original slave control system can be instantly switched to the main control system.

[0086] It is understandable that the slave control system also runs during the operation of the main control system. Therefore, the master-slave switch can be performed instantly during the execution of the third exception handling logic.

[0087] S403, based on the detection of abnormal current at the measuring point by the switched main control system, performs abnormal handling on the switched main control system.

[0088] Optionally, if the exception handling logic is the first exception handling logic, after the master-slave switch is completed, if the switched master control system also detects an abnormal current at the measuring point of the bypass circuit breaker of the valve group, the operating state of the switched master control system is immediately set to a minor fault state, and it is prohibited from sending valve group working commands to the bypass circuit breaker. At this time, the switched master control system is still the master control system and no master-slave switch is performed. If the switched master control system does not detect an abnormal current at the measuring point of the bypass circuit breaker of the valve group, the switched master control system maintains its original fault-free state and does not prohibit the sending of valve group working commands to the bypass circuit breaker.

[0089] For example, when the exception handling logic is the third exception handling logic, after the master-slave switch is completed, if the switched master control system detects an abnormal current at the measuring point of the bypass circuit breaker of the valve group, it immediately sets the operating state of the switched master control system to an emergency fault state and prohibits it from sending valve group working instructions to the bypass circuit breaker. At this time, the switched master control system is still the master control system, does not perform master-slave switch, and controls it to immediately execute the valve group ESOF instruction, that is, to stop the valve group. After the valve group's stop state is valid, the valve group working instruction is immediately invalidated. If the switched master control system does not detect an abnormal current at the measuring point of the bypass circuit breaker of the valve group, it controls it to continue to send valve group working instructions to the bypass circuit breaker. After the bypass circuit breaker of the valve group is valid in either open or closed position, the valve group working instruction is immediately invalidated.

[0090] Furthermore, after invalidating the valve group operation command, the operating status of the switched main control system is switched from emergency fault to minor fault, that is, from unavailable to available. However, the switched main control system is still prohibited from sending valve group operation commands to the bypass circuit breaker.

[0091] In this embodiment, taking the first and third exception handling logics as examples, the different ways of handling exceptions by different exception handling logics are analyzed in detail. It can take into account that the exception handling logics are different due to different operating conditions inside the DC transmission system, and can effectively improve the operational reliability of the DC transmission system while timely detecting exceptions.

[0092] For example, combining Figure 5 As shown, when the exception handling logic is the second or fourth exception handling logic, the exception handling process can specifically be as follows:

[0093] S501 updates the operating status of the control system to a fault status and prohibits the control system from sending valve group operation commands to the bypass circuit breaker.

[0094] Optionally, if the exception handling logic is the second exception handling logic, the control system can be updated from a fault-free operating state to a fault state (such as a minor fault state), and the control system can be prohibited from sending valve group working instructions to the bypass circuit breaker.

[0095] Furthermore, when the exception handling logic is the fourth exception handling logic, the control system can be updated from a fault-free operating state to a fault state (such as an emergency fault state), and the control system is prohibited from sending valve group working instructions to the bypass circuit breaker.

[0096] Optionally, in this embodiment, the fault state corresponding to the second fault handling logic is lower than the fault state corresponding to the fourth fault handling logic. It is understood that the slave control system corresponding to the second fault handling logic remains usable under minor fault conditions, while the slave control system corresponding to the fourth fault handling logic is unusable under emergency fault conditions.

[0097] S502, based on the main control system's detection of abnormal current at the measuring point, performs abnormal handling on the main control system.

[0098] Optionally, this embodiment handles the main control system differently depending on whether it detects an abnormal current at the measuring point or not. For example, if the main control system detects an abnormal current at the measuring point, its operating status is updated to a fault state, and the main control system is prohibited from sending valve group operating commands to the bypass circuit breaker; if the main control system does not detect an abnormal current at the measuring point, it is controlled to send valve group operating commands to the bypass circuit breaker.

[0099] Specifically, when the exception handling logic is the second exception handling logic, after setting the operating state of the control system to a minor fault state, if the main control system also detects an abnormality in the measuring current of the bypass circuit breaker of the valve group, the operating state of the main control system will also be set to a minor fault state, and the main control system will be prohibited from sending valve group working commands to the bypass circuit breaker; if the main control system does not detect an abnormality in the measuring current of the bypass circuit breaker of the valve group, the main control system will maintain its original fault-free state and will not be prohibited from sending valve group working commands to the bypass circuit breaker.

[0100] Furthermore, when the exception handling logic is the fourth exception handling logic, after the operating state controlled by the control system is set to the emergency fault state, if the main control system also detects an abnormality in the measuring current of the bypass circuit breaker of the valve group, then the main control system is also set to the emergency fault state, and the main control system is prohibited from sending valve group working instructions to the bypass circuit breaker. At the same time, it is controlled to immediately execute the valve group ESOF instruction, that is, to stop the valve group. After the valve group's stop state is valid, the valve group working instruction is immediately invalidated. If the main control system does not detect an abnormality in the measuring current of the bypass circuit breaker of the valve group, it is controlled to continue sending valve group working instructions to the bypass circuit breaker. After the bypass circuit breaker of the valve group is valid in either the open or closed position, the valve group working instruction is immediately invalidated.

[0101] Furthermore, after invalidating the valve group operation command, the main control system is switched from an emergency fault state to a minor fault state, that is, from an unavailable state to an available state. However, the main control system after the switch is still prohibited from sending valve group operation commands to the bypass circuit breaker.

[0102] In this embodiment, taking the second and fourth exception handling logics as examples, the different ways in which different exception handling logics handle exceptions are analyzed in detail. It can take into account that the exception handling logics are different due to different operating conditions inside the DC transmission system, and can effectively improve the operational reliability of the DC transmission system while timely detecting exceptions.

[0103] Figure 6 This is a flowchart illustrating an exception handling method in another embodiment. Based on the above embodiments, this embodiment provides an optional example of an exception handling method. (Combined with...) Figure 6 The specific implementation process is as follows:

[0104] S601, obtain the current operating status of the valve group.

[0105] S602, based on the current operating status of the valve group, determine whether the valve group operating command sent by the master-slave control system to the bypass circuit breaker is invalid; if yes, execute S603; if no, execute S606.

[0106] S603, determine whether the main control system has detected an abnormal current at the bypass circuit breaker's measuring point; if yes, execute S604; if no, execute S605.

[0107] S604 updates the operating status of the main control system to a minor fault state and prohibits the main control system from sending valve group operation commands to the bypass circuit breaker; delays the master-slave switch of the master-slave control system; and performs abnormal handling on the switched main control system based on the detection of abnormal current at the measuring point by the switched main control system.

[0108] S605 updates the operating status of the control system to a minor fault status and prohibits the control system from sending valve group operation commands to the bypass circuit breaker; based on the main control system's detection of abnormal current at the measuring point, it performs abnormal handling on the main control system.

[0109] S606, determine whether the main control system has detected an abnormal current at the bypass circuit breaker's measuring point; if yes, execute S607; if no, execute S608.

[0110] S607 updates the operating status of the main control system to an emergency fault state and prohibits the main control system from sending valve group operation commands to the bypass circuit breaker; immediately switches the main control system to slave; and handles the abnormality of the measured current by the switched main control system.

[0111] S608 updates the operating status of the control system to an emergency fault status and prohibits the control system from sending valve group operation commands to the bypass circuit breaker; based on the main control system's detection of abnormal current at the measuring point, it performs abnormal handling on the main control system.

[0112] The specific processes of S601-S608 described above can be found in the description of the above method embodiments. Their implementation principles and technical effects are similar, and will not be repeated here.

[0113] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0114] Based on the same inventive concept, this application also provides an exception handling apparatus for implementing the exception handling method described above. The solution provided by this apparatus is similar to the implementation scheme described in the above method; therefore, the specific limitations in one or more exception handling apparatus embodiments provided below can be found in the limitations of the exception handling method described above, and will not be repeated here.

[0115] In one embodiment, such as Figure 7 As shown, an exception handling device 1 is provided, including: an validity module 10, a processing logic module 20, and an exception handling module 30, wherein:

[0116] The validity determination module 10 is used to determine the validity of the valve group operation command sent by the master-slave control system corresponding to the valve group to the bypass circuit breaker based on the current operating state of the valve group; wherein, the bypass circuit breaker is used to control the valve group to switch operating states.

[0117] The logic determination module 20 is used to determine the result based on the validity and to determine the exception handling logic.

[0121] In one embodiment, the logic determination module 20 is specifically used for:

[0122] If the validity determination result is invalid, and the main control system first detects the abnormal current at the measuring point of the bypass circuit breaker, then the abnormal handling logic is determined to be the first abnormal handling logic.

[0123] If the validity determination result is invalid, and the abnormal current at the measuring point is detected first from the control system, then the abnormality handling logic is determined to be the second abnormality handling logic.

[0124] If the validity determination result is valid, and the main control system detects the abnormal current at the measuring point first, then the abnormality handling logic is determined to be the third abnormality handling logic.

[0125] If the validity determination result is valid, and the abnormal current at the measuring point is detected first from the control system, then the abnormality handling logic is determined to be the fourth abnormality handling logic.

[0126] In one embodiment, when the exception handling logic is a first exception handling logic or a third exception handling logic, the exception handling module 30 is specifically used for:

[0127] Update the operating status of the main control system to a fault state and prohibit the main control system from sending valve group operation commands to the bypass circuit breaker.
