[0003] In the related art, the alarm signals uploaded to the dispatch end are processed by dispatch personnel. According to a set rule, the dispatch personnel judge whether the power transformation equipment has an abnormal operation condition by using the reported alarm signals.

[0030] The encapsulation condition corresponding to the unknown type alarm signal encapsulator includes that, after the unknown type alarm signal encapsulator receives the alarm signal, a reset signal of the alarm signal is received within a preset waiting time period.

[0031] In a second aspect, an embodiment of the present application provides a power transformation device alarm signal processing apparatus, including:

The encapsulation operation includes: sending the alarm signal to a first signal encapsulator among a plurality of signal encapsulators; determining whether the alarm signal meets the encapsulation conditions of the first signal encapsulator; if the alarm signal is encapsulated in the first signal encapsulator and is not sent to any subsequent encapsulators, then the alarm signal is determined to meet the encapsulation conditions of the first signal encapsulator; if the alarm signal is sent to a second signal encapsulator selected from a plurality of signal encapsulators according to a preset order, the encapsulation process continues. The process continues until multiple signal encapsulators have been traversed, at which point it is determined that the alarm signal meets the encapsulation conditions of the first signal encapsulator. If the encapsulation operation is not completed after the alarm signal is encapsulated, an inspection command is issued based on the fact that the duration of the alarm signal is greater than a preset time threshold. Multiple encapsulators encapsulate most of the reported alarm signals, and inspection commands are only issued for alarm signals whose duration is greater than the time threshold. This allows for the identification of alarm signals that actually require scheduling from a large number of alarm signals, and scheduling operations are only performed on the alarm signals that actually require scheduling, thereby improving the processing efficiency of alarm signals in power equipment.

[0051] Figure 6 This is a schematic diagram of the structure of the alarm signal processing device for power equipment provided in the embodiments of this application.

[0052] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] Figure 1 The diagram illustrates an application scenario for the alarm signal processing method for power equipment provided in this application. Figure 1 As shown, in the power grid management system, alarm signals generated by multiple power equipment 101 in a substation are uploaded to an alarm signal monitoring system 102. Dispatchers 103 centrally process the alarm signals uploaded to the monitoring system 102. For each alarm signal that indicates abnormal operation of the power equipment, the dispatcher 103 issues an inspection instruction to the corresponding duty personnel 104 in the substation. The duty personnel 104 in the substation then perform equipment handling operations on the power equipment with abnormal operation, thereby ensuring the normal operation of the power equipment.

[0055] Numerous alarm signals are generated during the operation of power equipment, including alarm signals caused by equipment abnormalities or faults, alarm signals generated during maintenance and testing, alarm signals generated during power transmission or transformation operations, and other alarm signals generated during operation. For most of these alarm signals, since the power equipment's state can automatically recover within a short period, there are many redundant alarm signals uploaded to the alarm signal monitoring system 102. Therefore, it is unnecessary to send inspection instructions to on-duty personnel for these alarm signals to inspect and handle the relevant equipment.

[0056] Based on the above scenarios, it can be seen that the existing power grid management method, which involves dispatchers processing alarm signals one by one, suffers from the technical problem of low processing efficiency of alarm signals from substation equipment.

[0057] The method for processing alarm signals of power equipment provided in this application is used to solve the above-mentioned technical problems.

[0058] The subject of this invention can be an alarm signal monitoring system in a power grid management system, or other devices, systems, or equipment with data processing capabilities.

[0059] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0060] Figure 2 A flowchart illustrating the method for processing alarm signals of power equipment provided in this application embodiment. Figure One ,like Figure 2 As shown, the method includes:

[0061] S201, An alarm signal from the power equipment has been received.

[0062] For example, the alarm signal monitoring system can receive alarm signals generated by the power equipment in real time via wireless or wired communication, and automatically process the received alarm signals in real time.

[0063] S202, Perform encapsulation operation on alarm signals.

[0064] For the above packaging operation Figure 3 This is a flowchart illustrating the encapsulation operation of alarm signals provided in the embodiments of this application, as shown below. Figure 3 As shown, the encapsulation operation of the alarm signal includes:

[0065] S301. Send the alarm signal to the first signal encapsulator; wherein, after receiving the alarm signal, the first signal encapsulator determines whether the alarm signal meets the encapsulation conditions of the first signal encapsulator; the first signal encapsulator is a signal encapsulator determined from multiple signal encapsulators based on a preset order.

[0066] It should be noted that the signal encapsulator can be set in the built-in functional module of the alarm signal monitoring system, or it can be set in other devices or functional modules of the alarm signal monitoring system that can be accessed wirelessly or wiredly.

[0067] Encapsulators are used to filter out alarm signals that do not require scheduling operations from the scheduler, thereby reducing the number of times the scheduler needs to perform scheduling operations and improving the scheduler's work efficiency.

[0068] The alarm signal includes alarm content and carries equipment information of the substation equipment, so as to determine whether the alarm signal meets the encapsulation conditions of the first signal encapsulator using the alarm content and equipment information. The encapsulation conditions of the first signal encapsulator are preset encapsulation conditions.

[0069] As an example, different encapsulation conditions can be set for different types of alarm signals based on the statistical classification information of alarm signals.

[0070] As another example, encapsulation conditions can be set based on historical scheduling information for alarm signals to filter out alarm signals with low real-time scheduling requirements.

[0071] S302, in response to receiving the first feedback information output by the first signal encapsulator instructing the first signal encapsulator to encapsulate the alarm signal and stop sending the alarm signal to subsequent signal encapsulators; the first feedback information indicates that the alarm signal meets the encapsulation conditions of the first signal encapsulator.

[0072] It should be noted that the encapsulation operation ends when the alarm signal meets the encapsulation conditions and is encapsulated by the first signal encapsulator. This alarm signal does not require scheduling personnel to perform any scheduling operations.

[0073] For example, for alarm signals that do not require dispatchers to perform dispatching operations, the alarm signals can be stored locally and a query interface can be provided for dispatchers to manage the alarm signals in the future; for alarm signals that require dispatchers to perform dispatching operations, the alarm signals can be displayed in the front-end window of the alarm signal monitoring system and a dispatching function button can be provided for dispatchers to query in real time and click the dispatching function button to perform dispatching operations.

[0074] S303. In response to receiving the second feedback information output by the first signal encapsulator, a second signal encapsulator is selected from multiple signal encapsulators in a preset order, and the second signal encapsulator is used as a new first signal encapsulator to repeatedly perform the encapsulation operation until all multiple signal encapsulators have been traversed, and the encapsulation operation ends; wherein, the second feedback information indicates that the alarm signal does not meet the encapsulation conditions of the first signal encapsulator.

[0075] It should be noted that the preset order can be determined based on historical statistical data.

[0076] For example, multiple signal encapsulators can be ordered based on the number of alarm signals that meet the encapsulation conditions. If, according to the encapsulation conditions, signal encapsulator A can encapsulate more alarm signals than signal encapsulator B, then signal encapsulator A will be ordered before signal encapsulator B according to a preset order.

[0077] S203. In response to the failure to complete the encapsulation of the alarm signal after the encapsulation operation is completed, obtain the signal duration of the alarm signal.

[0078] S204. If the signal duration exceeds the preset time threshold, an inspection command is issued. The inspection command is used to instruct the substation equipment to be inspected based on the alarm signal.

[0079] It should be noted that multiple encapsulators can filter out most alarm signals that do not require scheduling operations by the dispatcher. By comparing the duration of the alarm signal with a preset time threshold, an inspection command can be issued for alarm signals whose duration exceeds the preset time threshold. This can further identify alarm signals with higher priority and prioritize their handling by on-duty personnel, thereby improving the efficiency of alarm signal processing.

[0080] The aforementioned preset time threshold can be determined based on the duration of historical alarm signals.

[0081] For example, statistics show that for more than 99% of alarm signals, the state of the power equipment can be automatically restored within ten minutes after the alarm signal is sent, so the time threshold can be set to ten minutes.

[0082] The method for processing alarm signals of power equipment provided in this application embodiment performs an encapsulation operation on the received alarm signals of the power equipment. The encapsulation operation includes: sending the alarm signal to a first signal encapsulator among a plurality of signal encapsulators; determining whether the alarm signal meets the encapsulation conditions of the first signal encapsulator; if the alarm signal is encapsulated in the first signal encapsulator and is not sent to any subsequent encapsulators, then the alarm signal is determined to meet the encapsulation conditions of the first signal encapsulator; if the alarm signal is sent to a second signal encapsulator selected from a plurality of signal encapsulators in a preset order, the encapsulation operation continues until all encapsulators are traversed. If multiple signal encapsulators are completed, the alarm signal is determined to meet the encapsulation conditions of the first signal encapsulator. If the encapsulation of the alarm signal is not completed after the encapsulation operation, an inspection command is issued based on the fact that the duration of the alarm signal is greater than a preset time threshold. Multiple encapsulators encapsulate most of the reported alarm signals, and inspection commands are only issued for alarm signals whose duration is greater than the time threshold. This enables the identification of alarm signals that actually need to be dispatched from a large number of alarm signals, and dispatch operations are only performed on the alarm signals that actually need to be dispatched, thereby improving the processing efficiency of alarm signals of power equipment.

[0083] Transformer equipment includes main transformer equipment and auxiliary transformer equipment; among which, main transformer equipment is used for power transmission or transformation; auxiliary transformer equipment is used to assist the main transformer equipment in power transmission or transformation.

[0084] For example, the main power equipment includes main transformers, switches, disconnectors, grounding switches, and busbars; the auxiliary power equipment includes station service transformers, fire alarm devices and fire extinguishing equipment of the fire protection system, and emergency lighting of the lighting system.

[0085] The alarm signals for these power equipment include action type and reset type. Action type alarm signals indicate that a regulating operation has been performed on the power equipment to adjust its state. Reset type alarm signals indicate that an action type alarm signal has been successfully cleared. The alarm signal content includes the signal name and the signal generation time. One reset type alarm signal can correspond to at least one action type alarm signal. Corresponding alarm signals have the same signal name, but the at least one action type alarm signal corresponding to each alarm signal has a different signal generation time.

[0086] For example, when a circuit breaker in a power distribution system trips, it sequentially generates a circuit breaker open / close status alarm signal C and a circuit breaker trip protection action alarm signal D. Five minutes later, the circuit breaker status recovers, generating a reset signal E. The reset signal E corresponds to alarm signals C and D. Alarm signals C, D, and E all share the same signal name, "circuit breaker trip," but alarm signals C and D have different signal generation times.

[0087] The following example, using the processing of alarm signals of the action type or reset type generated by the main power equipment or auxiliary power equipment, will further illustrate the technical solution of this application.

[0088] Figure 4 A flowchart illustrating the method for processing alarm signals of power equipment provided in this application embodiment. Figure Two ,like Figure 4 As shown, the processing method for alarm signals of power equipment includes:

[0089] S401, received an alarm signal generated by the power equipment.

[0090] The operation of S401 is the same as that of S201, and will not be described again here.

[0091] S402. If the alarm signal type is an action type, the alarm signal will be sent to the action signal library for storage.

[0092] S403. If the alarm signal type is a reset type, then search for at least one historical alarm signal in the action signal library and delete at least one historical alarm signal; wherein, the signal name of each of the at least one historical alarm signal matches the signal name of the alarm signal.

[0093] For S402 and S403, the action signal library is used to store alarm signals of the received action type. The alarm signals in the action signal library are used to obtain the signal duration of the alarm signal in subsequent operations. When a reset type alarm signal is received, it means that the alarm signal of the action type corresponding to that alarm signal in the action signal library has been cleared, and no scheduling operation is required. Therefore, it can be deleted from the action signal library.

[0094] For example, a timer can be set for each action signal in the action signal library. When it is necessary to obtain the signal duration of the alarm signal, the timer is triggered to execute a timed task to obtain the signal duration of the alarm signal.

[0095] S404, Perform encapsulation operation on alarm signals.

[0096] In the encapsulation operation, the encapsulators performing the encapsulation operation include defect alarm signal encapsulators, maintenance and test alarm signal encapsulators, power transmission and transformation operation-related alarm signal encapsulators, and unknown type alarm signal encapsulators. Defect alarm signal encapsulators are used to encapsulate alarm signals with known equipment defects that cannot be immediately repaired; maintenance and test alarm signal encapsulators are used to encapsulate alarm signals generated during equipment power outage maintenance; power transmission and transformation operation-related alarm signal encapsulators are used to encapsulate alarm signals generated during power transmission and transformation; and unknown type alarm signal encapsulators are used to encapsulate alarm signals of other types besides the above three.

[0097] For alarm signals generated by major power equipment, multiple signal encapsulators are included: defect alarm signal encapsulator, maintenance and test alarm signal encapsulator, power transmission and transformation operation-related alarm signal encapsulator, and unknown type alarm signal encapsulator.

[0098] For alarm signals generated by auxiliary power equipment, since the auxiliary power equipment is not involved in power transmission and transformation operations, multiple signal encapsulators are used, including: defect alarm signal encapsulator, maintenance and test alarm signal encapsulator, and unknown type alarm signal encapsulator.

[0099] The encapsulation conditions for the defect alarm signal encapsulator include: the alarm signal content includes a preset defect mark; the encapsulation conditions for the maintenance and testing alarm signal encapsulator include: the substation equipment corresponding to the alarm signal is in a maintenance and testing state; the encapsulation conditions for the transmission and transformation operation-related alarm signal encapsulator include: the substation equipment corresponding to the alarm signal is executing a transmission operation or a substation operation dispatching command; and the encapsulation conditions for the unknown type alarm signal encapsulator include: after receiving the alarm signal, the unknown type alarm signal encapsulator receives a reset signal of the alarm signal within a preset waiting time period.

[0100] For example, if the received alarm signal is generated by a major substation device, the alarm signal is sequentially sent to a defect alarm signal encapsulator. The defect alarm signal encapsulator stores all defect markers for all substation equipment. If any defect marker is detected in the alarm signal content, the alarm signal is encapsulated in the defect alarm signal encapsulator. Otherwise, the alarm signal is sent to a maintenance and testing alarm signal encapsulator.

[0101] The maintenance test alarm signal encapsulator stores equipment information for all devices in the substation undergoing maintenance and outage (this information can be determined by accessing the power grid topology, maintenance identification tags on the substation equipment, or maintenance dispatch instructions). If the equipment information carried by the alarm signal matches the equipment information of any device under maintenance, the alarm signal is encapsulated in the maintenance test alarm signal encapsulator. Otherwise, the alarm signal is sent to the transmission and transformation operation-related alarm signal encapsulator.

[0102] The power transmission and transformation operation-related alarm signal encapsulator stores equipment information for all devices in the substation currently executing power transmission or substation dispatching commands. If the equipment information carried by the alarm signal matches the equipment information of any device currently executing a power transmission or substation dispatching command, the alarm signal is encapsulated in the power transmission and transformation operation-related alarm signal encapsulator. Otherwise, the alarm signal is sent to an unknown type alarm signal encapsulator.

[0103] Inside the unknown type alarm signal encapsulator, when an alarm signal is received, a countdown timer is set inside the encapsulator, such as a countdown timer of 10 to 15 seconds, and the countdown timer is started. If the unknown type alarm signal encapsulator receives a reset signal corresponding to the alarm signal within the timer's countdown, the alarm signal is encapsulated in the unknown type alarm signal encapsulator. Otherwise, S405 is executed.

[0104] The other operations of S404 are the same as those of S202, and will not be described again here.

[0105] S405. In response to the failure to complete the encapsulation of the alarm signal after the encapsulation operation is completed, obtain the signal duration of the alarm signal.

[0106] Specifically, the duration of the alarm signal acquired above includes:

[0107] The system receives a time acquisition command, retrieves the alarm signal's generation time from the action signal library based on the command, and determines the alarm signal's duration based on the generation time and the current time. The time acquisition command is sent by the timer corresponding to the alarm signal in the action signal library.

[0108] For example, if the encapsulation of the alarm signal is not completed after the encapsulation operation, the timer corresponding to the alarm signal is triggered to execute a timed task. The timed task is set to send a time acquisition command every 10 to 15 seconds. When the time acquisition command is received, the signal generation time is obtained from the content of the alarm signal. Then, the signal duration of the alarm signal is equal to the difference between the current time and the signal generation time.

[0109] The other operations of S405 are the same as those of S203, and will not be repeated here.

[0110] S406. If the signal duration exceeds the preset time threshold, an inspection command is issued. The inspection command is used to instruct the substation equipment to be inspected based on the alarm signal.

[0111] The operation of S406 is the same as that of S204, and will not be repeated here.

[0112] It should be noted that when the substation duty personnel receive an inspection instruction, they will conduct an inspection of the equipment according to the instruction. If, during the inspection, the duty personnel have eliminated the equipment defect or abnormality, but the signal database still contains alarm signals related to the defect or abnormality indicating that the defect or abnormality has not been eliminated, the inspection instruction will be resent to the duty personnel to ensure that the equipment abnormality has been eliminated.

[0113] Specifically, when on-duty personnel handle equipment anomalies in response to alarm signals, after the handling is completed, they instruct the alarm signal monitoring system to verify any unrecovered alarm signals. If no corresponding alarm signal is found in the action signal database by checking the alarm signal name, the alarm signal monitoring system automatically completes the verification and signal processing. If a relevant alarm signal is found in the action signal database, the on-duty personnel are instructed to continue handling the anomaly.

[0114] When on-duty personnel report a defect in the equipment that cannot be eliminated temporarily, the alarm signal monitoring system marks the alarm signal as defective and abnormal, and the corresponding alarm signal is no longer checked. When on-duty personnel report that the defect has been eliminated, they instruct the alarm signal monitoring system to check any unresolved alarm signals. If no corresponding alarm signal is found in the action signal library by checking the alarm signal name, the alarm signal monitoring system automatically completes the review, removes the defect mark, and the signal processing is finished. If a related alarm signal is found in the action signal library, the on-duty personnel are instructed to continue handling the abnormality.
