Description

Technical Field

[0001] This invention relates to the field of power grid equipment monitoring technology, and in particular to a monitoring method and dispatch monitoring system for substation equipment. Background Technology

[0002] In the current field of power grid equipment monitoring technology, centralized signal monitoring mode is widely used.

[0003] When substation equipment malfunctions, it sends an alarm signal to the dispatch monitoring terminal. When dispatchers detect the alarm signal on the terminal, they notify substation personnel to inspect and address the equipment, eliminating the malfunction and restoring the alarm signal to normal. However, in some cases, eliminating substation equipment malfunctions requires adherence to the work plan, and there may be situations where the malfunction cannot be eliminated temporarily. In such cases, the alarm signal may not return to normal and may appear and disappear frequently, affecting dispatchers' monitoring of other substation equipment. In these situations, dispatchers will block the alarm signal to prevent it from being displayed and transfer monitoring authority for the malfunctioning substation equipment to substation personnel. These personnel will then implement risk control measures according to procedures, such as regular maintenance or inspections, to manage the risk.

[0004] However, there is a possibility that substation personnel may eliminate the substation equipment anomaly but forget to notify dispatchers to lift the alarm signal blockade in order to restore the dispatch monitoring terminal's monitoring of the substation equipment anomaly. Because the substation personnel eliminated the anomaly, they no longer take risk control measures such as inspections at the substation equipment site. As a result, when the substation equipment anomaly occurs again, neither the dispatch monitoring terminal nor the substation personnel are aware of it, nor do they take risk control measures, causing the substation equipment anomaly to worsen and causing serious impact. Summary of the Invention

[0005] This invention provides a method for monitoring substation equipment and a dispatch monitoring system to improve the monitoring efficiency of the dispatch monitoring terminal while reducing the risk of missed monitoring.

[0006] In a first aspect, the present invention provides a method for monitoring substation equipment, comprising:

[0007] When receiving an alarm signal from an abnormal substation device, the alarm signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal displays the alarm information corresponding to the alarm signal.

[0008] Upon receiving a blocking instruction for the abnormal substation equipment, the alarm signal sent by the abnormal substation equipment is blocked, and a timer is started to obtain a first timer value.

[0009] When the first timing value reaches the first preset threshold, the blocking of alarm signals sent by the abnormal substation equipment is automatically lifted.

[0010] Furthermore, after automatically unblocking the alarm signals sent by the abnormal substation equipment, the method also includes:

[0011] Summarize the current status of the abnormal substation equipment;

[0012] When the current state of the abnormal substation equipment is in an active state, an action signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal displays the action information corresponding to the action signal.

[0013] When the current status of the abnormal substation equipment is a return status, a return signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the return information corresponding to the return signal.

[0014] Furthermore, when blocking alarm signals sent by the abnormal substation equipment, the method also includes:

[0015] An abnormal blocking flag is added to the alarm signal sent by the abnormal substation equipment;

[0016] After automatically unblocking the alarm signals sent by the abnormal substation equipment, the process also includes:

[0017] Upon receiving an alarm signal from the abnormal substation equipment, the alarm signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal displays the alarm information corresponding to the alarm signal and the abnormal blocking mark attached to the alarm signal.

[0018] Furthermore, when automatically unblocking the alarm signals sent by the abnormal substation equipment, the following steps are also included:

[0019] Start timing and obtain the second timing value;

[0020] After automatically unblocking the alarm signals sent by the abnormal substation equipment, the process also includes:

[0021] If the number of alarm signals received from the abnormal substation equipment reaches a first preset number before the second timing value reaches the second preset threshold, the alarm signals sent by the abnormal substation equipment will be automatically blocked.

[0022] Furthermore, after automatically unblocking the alarm signals sent by the abnormal substation equipment, the method also includes:

[0023] When the second timing value reaches the second preset threshold, if the number of alarm signals received from the abnormal substation equipment is less than the first preset number and greater than 0, then the second timing value is set to 0 and the timing restarts.

[0024] Furthermore, after automatically unblocking the alarm signals sent by the abnormal substation equipment, the method also includes:

[0025] When the second timing value reaches the third preset threshold, if the number of alarm signals received from the abnormal substation equipment is 0, a first prompt message is displayed on the dispatch monitoring terminal, wherein the first prompt message is used to indicate that the abnormality has been eliminated, and the third preset threshold is greater than or equal to the second preset threshold.

[0026] Furthermore, when blocking alarm signals sent by the abnormal substation equipment, the method also includes:

[0027] An abnormal blocking flag is added to the alarm signal sent by the abnormal substation equipment;

[0028] When the second timing value reaches the third preset threshold, if the number of alarm signals received from the abnormal substation equipment is 0, the method further includes:

[0029] Remove the abnormal blocking flag attached to the alarm signal sent by the abnormal substation equipment.

[0030] Furthermore, after automatically blocking the alarm signals sent by the abnormal substation equipment, the method also includes:

[0031] The number of times the alarm signals sent by the abnormal substation equipment are automatically blocked is determined as the first cycle number;

[0032] When the first number of cycles exceeds the first preset number of cycles, a second prompt message is displayed on the scheduling monitoring terminal, wherein the second prompt message is used to indicate that the progress of anomaly elimination has been delayed.

[0033] Furthermore, after automatically unblocking the alarm signals sent by the abnormal substation equipment, the method also includes:

[0034] When the second timing value reaches the third preset threshold, if the number of alarm signals received from the abnormal substation equipment is 0, the first cycle count is set to 0.

[0035] Secondly, the present invention provides a scheduling and monitoring system, comprising:

[0036] A scheduling processing device and a scheduling monitoring terminal connected to the scheduling processing device;

[0037] The scheduling and processing device is used to execute the monitoring method for substation equipment described in the first aspect.

[0038] The substation equipment monitoring method and dispatch monitoring system provided in this invention, when the dispatch monitoring terminal receives alarm signals and displays the corresponding alarm information, allows dispatch personnel to block alarm signals sent by abnormal substation equipment. This solves the problem of frequent issuance, cancellation, and issuance of alarm signals from abnormal substations, which interferes with the monitoring by dispatch personnel at the dispatch monitoring terminal. Simultaneously, when the dispatch personnel block alarm signals sent by abnormal substation equipment, a timer is started to obtain a first time value. When the first time value reaches a first preset threshold, the block on the alarm signals sent by the abnormal substation equipment is automatically released. This solves the problem of risks caused by failure to unlock alarm signals in a timely manner after the abnormality of substation equipment is cleared, thereby improving the monitoring efficiency of the dispatch monitoring terminal while reducing the risk of missed monitoring.

[0046] Figure 1 This is a flowchart illustrating a method for monitoring substation equipment according to an embodiment of the present invention. This method is applicable to monitoring substation equipment scenarios and can be executed by a scheduling processing device. The scheduling processing device can be implemented in hardware and / or software and can be configured within a scheduling monitoring system. Figure 1 As shown, the method includes:

[0047] S110. When receiving an alarm signal from an abnormal substation device, send an alarm signal to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the alarm information corresponding to the alarm signal.

[0048] Abnormal substation equipment refers to substation equipment that has malfunctioned and cannot operate normally.

[0049] The dispatch and monitoring terminal refers to the working terminal that monitors and dispatches the overall operation of the power grid and substations.

[0050] Alarm signals are signals sent when substation equipment malfunctions. Alarm signals can be sent to the dispatch monitoring terminal via remote control units (RTUs). A RTU is a device that can remotely transmit and receive signals and process them. It can be installed in both the substation and the dispatch monitoring terminal to modulate and download signals transmitted via line carrier waves, dedicated optical cables, etc., to assist the two working terminals in completing information exchange and then executing corresponding task instructions.

[0051] Specifically, to ensure normal power supply from the substation, the operating status of the substation equipment needs to be monitored. When abnormalities occur in the substation equipment, substation personnel need to resolve them. This work includes monitoring, acquiring information, dispatching resources, and eliminating substation equipment abnormalities. By setting up a dispatch monitoring terminal, this task of monitoring and dispatching the substation equipment's operating status can be delegated to the dispatch monitoring terminal, reducing the workload of staff while improving work efficiency through the cooperation between the two terminals. Furthermore, both the substation and the dispatch monitoring terminal have a comprehensive understanding of the substation's status.

[0052] For example, when a substation device malfunctions, the malfunctioning device sends an alarm signal to the dispatch monitoring terminal via a remote motor. This alarm signal contains alarm information about the power grid and the substation device. The alarm signal is modulated by the remote motor, and the alarm information of the malfunctioning substation device is displayed on the dispatch monitoring terminal. Dispatchers can view the information on the faults that have occurred in the power grid and / or substation device contained in the alarm information, and can monitor and dispatch the substation device.

[0053] Alarm information refers to fault information that occurs in abnormal substation equipment. Examples include switch tripping (including tripping not performed manually) and abnormal grounding switch position. However, it is not limited to faults occurring in the abnormal substation equipment itself, but can also be signal communication faults between abnormal substation equipment.

[0054] S120. Upon receiving a blocking instruction for abnormal substation equipment, the alarm signal sent by the abnormal substation equipment is blocked, and a timer is started to obtain the first timer value.

[0055] When dispatchers block alarm signals sent by abnormal substation equipment, they input a blocking command to the dispatch processing device. After receiving the blocking command for the abnormal substation equipment, the dispatch processing device controls the dispatch monitoring terminal to stop displaying the alarm information corresponding to the alarm signal. At this time, the abnormal substation equipment can still send alarm signals.

[0056] The first timing value refers to the timing value that begins after the dispatch monitoring terminal receives an alarm signal sent by an abnormal substation device, the dispatcher views the alarm information and blocks the corresponding alarm signal. It can represent the length of time the corresponding alarm signal is blocked, that is, the length of time the dispatch monitoring terminal no longer displays the alarm information corresponding to the corresponding alarm signal.

[0057] Specifically, after receiving alarm information from abnormal substation equipment, dispatchers at the monitoring terminal learn the status of the substation equipment and can subsequently monitor the relevant units or devices of the abnormal substation equipment within the substation and power grid, and allocate corresponding work tasks. The troubleshooting of the abnormal substation equipment still requires the substation personnel. Therefore, after receiving alarm information from abnormal substation equipment, dispatchers can transfer monitoring authority to substation personnel. The troubleshooting tasks for the abnormal substation equipment are scheduled by the substation personnel according to the actual situation, and the feedback of troubleshooting information (normal operation information of the substation equipment) is also performed by the substation personnel.

[0058] When dispatchers discover alarm signals from abnormal substation equipment, and these are confirmed as abnormal by on-site inspection by substation personnel and cannot be eliminated temporarily, the abnormal substation equipment may frequently send alarm signals to the dispatch monitoring terminal. This causes the dispatch monitoring terminal to display alarm information frequently, thus interfering with the dispatchers' monitoring. In this case, the dispatchers can transfer the abnormal substation equipment to on-site substation personnel for monitoring and manually click the alarm signal blocking button to block the alarm signals sent by the abnormal substation equipment. This prevents the dispatch monitoring terminal from frequently displaying alarm signals from the same abnormal substation equipment, which would affect the dispatchers' monitoring.

[0059] The method by which dispatchers block alarm signals sent by abnormal substation equipment can be set according to the overall power grid, substation equipment and the device configuration of the dispatch monitoring terminal. For example, a button to block alarm signals can be set on the dispatch monitoring terminal. The dispatcher selects the abnormal substation equipment and manually presses the button to block the alarm signals sent by the abnormal substation equipment, but it is not limited to this.

[0060] After blocking the alarm signals sent by abnormal substation equipment, if the fault of the abnormal substation equipment is not eliminated, the alarm signals of the same abnormal substation equipment that are frequently sent to the dispatch monitoring terminal will not be displayed, thereby avoiding interference with the monitoring of dispatch personnel.

[0061] After blocking the alarm signal sent by the abnormal substation equipment at the dispatch monitoring terminal, a timer is started and recorded as the first timer value.

[0062] S130. When the first timing value reaches the first preset threshold, the blocking of alarm signals sent by abnormal substation equipment is automatically lifted.

[0063] If the alarm signals sent by abnormal substation equipment are blocked, and the fault of the abnormal substation equipment is eliminated by the substation personnel, but the substation personnel do not inform the dispatcher that the fault of the abnormal substation equipment has been eliminated, and the blocking of the alarm signals sent by the abnormal substation equipment is not lifted, if the fault of the abnormal substation equipment occurs again after the fault is eliminated, the alarm signals sent by the abnormal substation equipment to the dispatch monitoring terminal will not be displayed on the dispatch monitoring terminal. The dispatcher will not be able to obtain the alarm information of the abnormal substation equipment and thus cannot carry out dispatching, which may pose a risk.

[0064] In this embodiment, by setting a first preset threshold and comparing a first timing value with the first preset threshold, it is determined whether to unblock the alarm signal sent by the abnormal substation equipment, thereby regaining knowledge of the operating status of the abnormal substation equipment. Specifically, if the first timing value is greater than the first preset threshold, the blocking of the alarm signal sent by the abnormal substation equipment is automatically released, ensuring that the alarm signal is not blocked for an extended period. The dispatch monitoring terminal can automatically acquire and display the alarm signal sent by the abnormal substation equipment again after a certain period (the first preset threshold), preventing the abnormal substation equipment from malfunctioning again without timely detection and thus avoiding potential risks.

[0065] The first preset threshold refers to the maximum value that the first timing value can reach. The purpose of setting this value is to prevent dispatchers from losing access to alarm signals from abnormal substation equipment for an extended period of time. Therefore, this value can be set according to actual needs, such as one week or ten days, but it is not limited to this.

[0066] For example, the operation of automatically unblocking the alarm signal sent by abnormal substation equipment can be executed by a pre-set program that automatically unblocks the corresponding alarm signal when the first time value is greater than the first preset threshold information. Specifically, it involves obtaining the first time value greater than the first preset threshold information and unblocking the corresponding alarm signal, but it is not limited to this. It can be adjusted according to the actual situation of the dispatch monitoring terminal and the substation equipment, and is not limited here.

[0067] Specifically, when the first timing value exceeds the first preset threshold, the status of the abnormal substation equipment needs to be reacquired according to actual needs, enabling dispatchers to monitor the abnormal substation equipment. If alarm signals from the abnormal substation equipment are frequently received again at this time, affecting the dispatchers' monitoring, the dispatchers can confirm with the substation personnel and manually block it again. This reduces the impact on the dispatchers' monitoring of other substation equipment, improves the monitoring efficiency of the dispatch monitoring terminal, and reduces the risk of missed monitoring. Simultaneously, automatic unlocking also reduces the workload of dispatchers.

[0068] The substation equipment monitoring method provided in this invention addresses the problem of frequent alarm signal transmission, cancellation, and retransmission from abnormal substation equipment, which interferes with the monitoring by dispatchers. Simultaneously, when the dispatcher blocks the alarm signal, a first timer is started, and when the first timer reaches a first preset threshold, the block is automatically lifted. This solves the risk caused by the failure to promptly unlock alarm signals after the substation equipment malfunctions, thereby improving the monitoring efficiency of the dispatcher and reducing the risk of missed monitoring.

[0069] Optionally, after automatically unblocking the alarm signals sent by abnormal substation equipment, the following steps are also included:

[0070] Summarize the current status of abnormal substation equipment.

[0071] When the current status of abnormal substation equipment is in an active state, an action signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the action information corresponding to the action signal.

[0072] When the current status of the abnormal substation equipment is a return status, a return signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the return information corresponding to the return signal.

[0073] The operation of recalling the current status of abnormal substation equipment can be achieved through a remote machine; the current status of abnormal substation equipment can include an action status and a return status; the action status is an abnormal status, and the return status is a normal working status.

[0074] After the blocking of alarm signals sent by abnormal substation equipment is automatically lifted, the abnormality of the abnormal substation equipment may have been eliminated, and the dispatch monitoring terminal may not receive the alarm signals sent by the abnormal substation equipment. At this time, the current status of the substation equipment can be actively summoned and verified through a remote machine, thereby promptly confirming the current status of the substation equipment and keeping the risk of missed monitoring within a controllable range.

[0075] Furthermore, when the current state of the abnormal substation equipment is in an active state, an action signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the action information corresponding to the action signal.

[0076] Action signals refer to the signals output when substation equipment is in an operational state; action information can display abnormal status information of substation equipment, and action information can be obtained by modulating action signals. It should be noted that the output and modulation of action signals can be performed by a remote control unit, but is not limited to this, and can be set according to actual needs.

[0077] The dispatch monitoring terminal actively summons and verifies the current status of substation equipment via a remote unit. When the current status of abnormal substation equipment is in an active state, it can be determined that the substation equipment is in an abnormal state. The remote unit modulates and downloads the action signal and sends it to the dispatch monitoring terminal. The dispatch monitoring terminal displays the action information corresponding to the action signal, enabling dispatchers to monitor abnormal substation equipment and perform dispatching based on the action information. For example, the alarm signal sent by the abnormal substation equipment can be blocked again, and the monitoring authority can be transferred to the substation personnel.

[0078] Furthermore, when the current status of the abnormal substation equipment is a return status, a return signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the return information corresponding to the return signal.

[0079] The return signal refers to the signal output when the substation equipment is in the return state; the return information can display the status information of abnormal substation equipment, and the return information can be obtained by modulating the return signal. It should be noted that the output and modulation of the return signal can be accomplished by a remote control unit, but is not limited to this, and can be set according to actual needs.

[0080] The dispatch monitoring terminal actively summons and verifies the current status of substation equipment via a remote unit. When the current status of the abnormal substation equipment is a return status, it can be known that the substation equipment is in normal working condition, that is, the abnormality may have been eliminated. The remote unit will modulate, download, and send the return signal to the dispatch monitoring terminal. The dispatch monitoring terminal displays the return information corresponding to the return signal, enabling dispatchers to monitor the substation equipment and perform dispatching based on the return information, such as verifying with on-site substation personnel to determine whether the abnormality of the substation equipment has been eliminated.

[0081] It should be noted that by using a remote starter to recall the current status of abnormal substation equipment, the dispatch monitoring terminal can display action information or return information, facilitating dispatchers to determine whether the substation equipment abnormality has been resolved. There are three scenarios:

[0082] 1. The dispatch monitoring terminal only displays action information once, that is, when the substation equipment is in an action state (abnormal state).

[0083] 2. The dispatch monitoring terminal only displays the return information once, that is, the substation equipment is in the return state (normal working state), at which point the abnormality may have been eliminated.

[0084] 3. The frequent alternation of action information and return information indicates abnormal fluctuations in substation equipment, which may affect the monitoring by dispatchers.

[0085] Dispatchers can promptly determine the current status of substation equipment through the information displayed on the dispatch monitoring terminal, thereby keeping the risk of missed monitoring within a controllable range.

[0086] Optionally, when blocking alarm signals sent by abnormal substation equipment, the following may also be included:

[0087] Add an abnormal blocking flag to alarm signals sent by abnormal substation equipment.

[0088] After automatically unblocking the alarm signals sent by abnormal substation equipment, it also includes:

[0089] When an alarm signal is received from an abnormal substation device, an alarm signal is sent to the dispatch monitoring terminal so that the dispatch monitoring terminal can display the alarm information corresponding to the alarm signal and the abnormal blocking mark attached to the alarm signal.

[0090] Specifically, when blocking alarm signals sent by abnormal substation equipment, an abnormal blocking mark is added to the alarm signals sent by the abnormal substation equipment. At this time, the alarm signals sent by the abnormal substation equipment are blocked and will no longer be displayed by the dispatch monitoring terminal.

[0091] As mentioned above, when the first timing value exceeds the first preset threshold, the blocking of alarm signals sent by the abnormal substation equipment is automatically lifted. At this time, the alarm signals sent by the abnormal substation equipment can be sent to the dispatch monitoring terminal and the display is restored. If the abnormality of the abnormal substation equipment is not eliminated, the abnormal substation equipment will continue to send alarm signals. After receiving the alarm signal sent by the abnormal substation equipment, the dispatch processing device controls the dispatch monitoring terminal to display the alarm information corresponding to the alarm signal and the abnormal blocking mark attached to the alarm signal, so as to assist dispatchers in distinguishing the alarm signals sent by the abnormal substation equipment. Among them, the alarm signal with the abnormal blocking mark is the alarm signal sent by the abnormal substation equipment that has been manually blocked; the alarm signal without the abnormal blocking mark is the alarm signal sent by the abnormal substation equipment that has not been blocked.

[0092] The technical solution of this invention involves adding an abnormal blocking mark to the alarm signal sent by the dispatcher when the dispatcher blocks the alarm signal sent by the abnormal substation equipment. Then, when the block is automatically lifted, the dispatch monitoring terminal displays the alarm information corresponding to the alarm signal and the abnormal blocking mark added to the alarm signal for the dispatcher's reference, so that the dispatcher can identify and distinguish the abnormal substation equipment that sent the alarm signal through the abnormal blocking mark.

[0093] Optionally, when automatically releasing the blockade of alarm signals sent by abnormal substation equipment, the following also applies:

[0094] Start timing and obtain the second timing value.

[0095] After automatically unblocking the alarm signals sent by abnormal substation equipment, it also includes:

[0096] If the number of alarm signals received from abnormal substation equipment reaches the first preset number before the second timing value reaches the second preset threshold, the alarm signals sent by the abnormal substation equipment will be automatically blocked.

[0097] The second timing value refers to the duration from the start of the automatic release of the blockade on alarm signals sent by abnormal substation equipment.

[0098] Specifically, when the first timing value is greater than the first preset threshold, the blocking of alarm signals sent by abnormal substation equipment is automatically lifted, and timing begins to obtain the second timing value.

[0099] After the blocking of alarm signals sent by abnormal substation equipment is automatically lifted, if the abnormal substation equipment still malfunctions, it can send alarm signals to the dispatch monitoring terminal via a remote unit. If the number of alarm signals sent by the abnormal substation equipment reaches the first preset number before the second time value reaches the second preset threshold, it indicates that the abnormal substation equipment is sending alarm signals too frequently, which will interfere with the dispatcher's monitoring. In this case, the alarm signals sent by the abnormal substation equipment will be automatically blocked again to ensure that the dispatcher's monitoring is not interfered with, and no manual operation is required, reducing the dispatcher's workload.

[0100] The second preset threshold refers to the upper limit threshold of the second time value set in advance. The second preset threshold can be set according to actual needs, such as 1 day, but is not limited to this.

[0101] The first preset quantity refers to the number of alarm signals sent by abnormal substation equipment before the second timing value reaches the second preset threshold, which does not affect the upper limit threshold of the dispatcher.

[0102] If the number of alarm signals is less than the first preset number before the second time value reaches the second preset threshold, it is determined that the alarm signals sent by the abnormal substation equipment are infrequent and have little interference with the dispatcher's monitoring. If the number of alarm signals reaches the first preset number before the second time value reaches the second preset threshold, it is determined that the alarm signals sent by the abnormal substation equipment are relatively frequent and have a greater interference with the dispatcher's monitoring.

[0103] The first preset number can be set according to actual needs, such as 10 times, but is not limited to this.

[0104] The technical solution of this invention starts timing when automatically unblocking alarm signals sent by abnormal substation equipment, obtains a second timing value, and sets a second preset threshold. When the second timing value does not reach the second preset threshold, the number of alarm signals received from the abnormal substation equipment is determined and a first preset number is set. When the number of alarm signals received from the abnormal substation equipment reaches the first preset number, the alarm signals sent by the abnormal substation equipment are automatically blocked. This solves the problem that alarm signals are sent too frequently when automatically unblocking abnormal substation equipment, affecting the monitoring of dispatchers. It realizes the automatic blocking of alarm signals sent by abnormal substation equipment, thereby ensuring that the monitoring of dispatchers is not affected.

[0105] Optionally, after automatically unblocking the alarm signals sent by abnormal substation equipment, the following steps are also included:

[0106] When the second timing value reaches the second preset threshold, if the number of alarm signals received from abnormal substation equipment is less than the first preset number but greater than 0, the second timing value is set to 0 and the timing restarts.

[0107] Specifically, when the second timing value reaches the second preset threshold, if the number of alarm signals sent by the abnormal substation equipment received by the dispatch monitoring terminal does not reach the first preset number, then the alarm signals are not frequent and do not affect the monitoring of the dispatchers. Therefore, it can be determined whether the alarm signals affect the monitoring of the dispatchers by judging whether the number of alarm signals sent by the abnormal substation equipment received by the dispatch monitoring terminal reaches the first preset number when the second timing value reaches the second preset threshold.

[0108] Specifically, when the second timer value reaches the second preset threshold, an alarm signal is received from the abnormal substation equipment. However, if the number of alarm signals does not reach the first preset number, it indicates that the alarm signals from the abnormal substation equipment will not affect the dispatcher's monitoring. In this case, there is no need to block the alarm signals from the abnormal substation equipment. However, if the number of alarm signals is greater than 0, the substation equipment abnormality has not been eliminated. In this case, the second timer value is set to 0, and the timing restarts. The alarm signals can continue to be received and displayed by the dispatcher's monitoring terminal, and the dispatcher can continue to monitor the abnormal substation equipment. Before the second timer value reaches the second preset threshold, the relationship between the number of alarm signals from the abnormal substation equipment and the first preset number is determined again to decide whether automatic blocking is necessary based on the actual situation.

[0109] Optionally, after automatically unblocking the alarm signals sent by abnormal substation equipment, the following steps are also included:

[0110] When the second timing value reaches the third preset threshold, if the number of alarm signals received from the abnormal substation equipment is 0, the first prompt information is displayed on the dispatch monitoring terminal. The first prompt information is used to indicate that the abnormality has been eliminated and the third preset threshold is greater than or equal to the second preset threshold.

[0111] Specifically, if the abnormal substation equipment does not send an alarm signal when the second time value reaches the third preset threshold, it indicates that the abnormality of the abnormal substation equipment is likely to be eliminated. At this time, the control and dispatch monitoring terminal displays the first prompt message that the abnormality has been eliminated, so as to prompt the dispatcher that the abnormality of the abnormal substation equipment may have been eliminated. The dispatcher and the on-site substation personnel should verify. If it is confirmed that the abnormality has been eliminated, no action is required. If it is confirmed that the abnormality has not been eliminated, the dispatcher can manually block the alarm signal again, but it is not limited to this.

[0112] The third preset threshold is greater than or equal to the second preset threshold. The third preset threshold can be set according to actual needs, such as 2 days, but is not limited to this.

[0113] Optionally, when blocking alarm signals sent by abnormal substation equipment, the following may also be included:

[0114] Add an abnormal blocking flag to alarm signals sent by abnormal substation equipment.

[0115] When the second timing value reaches the third preset threshold, if the number of alarm signals received from abnormal substation equipment is 0, the following also applies:

[0116] Remove the abnormal blocking flag attached to the alarm signal sent by the abnormal substation equipment.

[0117] Specifically, when dispatchers block alarm signals sent by abnormal substation equipment, an abnormal blocking mark is attached to the alarm signal. Then, when the blocking of alarm signals sent by abnormal substation equipment is automatically lifted, the dispatch monitoring terminal displays the alarm information corresponding to the alarm signal and the abnormal blocking mark attached to the alarm signal for dispatchers to refer to, so that dispatchers can identify and distinguish the abnormal substation equipment that sent the alarm signal through the abnormal blocking mark.

[0118] Furthermore, if the abnormal substation equipment does not send an alarm signal when the second timing value reaches the third preset threshold, it can be considered that the abnormality of the abnormal substation equipment has been eliminated. At this time, the abnormal blocking mark attached to the alarm signal sent by the abnormal substation equipment will be removed. When the dispatch monitoring terminal displays the alarm information corresponding to the alarm signal sent by the abnormal substation equipment, the abnormal blocking mark will no longer be attached.

[0119] Furthermore, the alarm signal will no longer be automatically blocked, and a first notification message indicating that the anomaly has been eliminated will be pushed through the dispatch monitoring terminal. The dispatch personnel and the on-site substation personnel will then verify this. If it is confirmed that the anomaly has been eliminated, no action is required, and the monitoring of the abnormal substation equipment will return to normal. If it is confirmed that the anomaly has not been eliminated, the dispatch personnel can manually block the alarm signal again, but this is not the only option.

[0120] Optionally, after automatically blocking alarm signals sent by abnormal substation equipment, the following additional steps are also included:

[0121] The number of times the alarm signals sent by abnormal substation equipment are automatically blocked is defined as the first cycle count.

[0122] When the number of the first loop exceeds the first preset number of loops, a second prompt message is displayed on the scheduling monitoring terminal. The second prompt message is used to indicate that the progress of anomaly elimination has been delayed.

[0123] As described above, after blocking the alarm signals sent by the abnormal substation equipment at the dispatch monitoring end, a timer is started and recorded as the first timer value. When the first timer value reaches the first preset threshold, the blocking of the alarm signals sent by the abnormal substation equipment is automatically lifted so that the alarm signals sent by the abnormal substation equipment will not be blocked for a long time. When the blocking of the alarm signals sent by the abnormal substation equipment is automatically lifted, the timer starts and the second timer value is obtained.

[0124] If the number of alarm signals received from abnormal substation equipment reaches the first preset number before the second time value reaches the second preset threshold, the alarm signals sent by the abnormal substation equipment will be automatically blocked to avoid affecting the monitoring of dispatchers. When the alarm signals sent by the abnormal substation equipment are automatically blocked, the time will be counted again and recorded as the first time value. When the first time value reaches the first preset threshold, the blocking of the alarm signals sent by the abnormal substation equipment will be automatically lifted again, and this cycle will continue.

[0125] During this process, the number of times the alarm signals sent by the abnormal substation equipment are automatically blocked is determined as the first cycle count. The first cycle count is the number of cycles in which the blocking of the alarm signals sent by the abnormal substation equipment is automatically lifted, and the number of cycles in which the blocking of the alarm signals sent by the abnormal substation equipment is automatically lifted.

[0126] When the number of cycles exceeds the first preset number of cycles, it indicates that the abnormality of the substation equipment has not been eliminated for a long time. At this time, a second prompt message is displayed on the dispatch monitoring terminal to remind the dispatcher that the elimination progress of the abnormality of the substation equipment is lagging behind. The dispatcher can verify with the substation personnel and remind them to handle the abnormality in a timely manner.

[0127] The number of cycles in the first cycle can be set according to actual needs, such as 2, 3, 4 or 5 times, etc., and is not limited here.

[0128] Optionally, after automatically unblocking the alarm signals sent by abnormal substation equipment, the following steps are also included:

[0129] When the second timing value reaches the third preset threshold, if the number of alarm signals received from abnormal substation equipment is 0, the first cycle count is set to 0.

[0130] Specifically, as mentioned above, if the abnormal substation equipment does not send an alarm signal when the second time value reaches the third preset threshold, it can be considered that the abnormality of the abnormal substation equipment has been eliminated. At this time, the first cycle count is set to 0, the alarm signal is no longer automatically blocked, and the monitoring of the abnormal substation equipment is restored to normal.

[0133] For example, Figure 3 This is a schematic diagram of a scheduling processing device provided in an embodiment of the present invention, as shown below. Figure 2 and Figure 3 As shown, the scheduling processing device 10 includes:

[0134] The alarm information display module 21 is used to send an alarm signal to the dispatch monitoring terminal when receiving an alarm signal from an abnormal substation device, so that the dispatch monitoring terminal can display the alarm information corresponding to the alarm signal.
