Description

Technical Field

[0001] This invention relates to an anomaly early warning method and system for verifying the status of power grid equipment under centralized control, belonging to the technical field of power grid automation systems. Background Technology

[0002] In modern power grid operation and maintenance, substation centralized monitoring systems play a crucial role. To ensure the safety of maintenance, testing, and other work, operators need to tag or remove tags from the corresponding equipment in the centralized control system, such as attaching "Maintenance," "Not in Operation," or "Do Not Open" signs. These operations aim to clarify the equipment status, prevent misoperation, and are an important guarantee for safe power grid operation.

[0003] However, the existing tagging and detour operations mainly rely on manual execution by maintenance personnel and subsequent verification. In a real production environment, the following problems can easily arise due to human error: 1. After the equipment was repaired and powered on, the maintenance tag was not removed, causing the system status to be inconsistent with the actual on-site status; 2. The equipment was not properly tagged after a power outage for maintenance, resulting in a blind spot in the monitoring system; 3. Incorrect sign type, such as hanging a maintenance sign on operating equipment; 4. A switch with a "Do Not Open" sign was abnormally opened, and the system failed to issue an alarm in a timely manner. This problem can cause discrepancies between the equipment status displayed in the centralized control system and the actual operating status on site, creating monitoring blind spots and safety hazards, and potentially leading to safety accidents in severe cases.

[0004] While existing technologies employ methods for status determination based solely on remote signaling location or electrical topology, they lack a comprehensive judgment mechanism that combines location criteria, measurement criteria, and topology criteria. Single criteria have significant limitations: remote signaling may transmit abnormally due to contact jitter; measurements may result in misjudgments due to zero drift or transformer errors; and topology analysis may lead to inaccurate status readings due to model update lags. More importantly, existing technologies lack an automatic verification mechanism for the accuracy of tagging operations, failing to establish closed-loop management for tagging and untagning operations. Summary of the Invention

[0005] The purpose of this invention is to provide an abnormal early warning method and system for verifying the status of power grid equipment tagging and removal based on a centralized control system. It aims to achieve accurate verification, intelligent reminders, and abnormal early warnings for tagging and removal operations through a multi-dimensional status comprehensive judgment mechanism and intelligent monitoring and reminder methods, thereby forming a closed-loop management of tagging and removal operations and improving the safety and efficiency of power grid operation and maintenance.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution.

[0007] In a first aspect, the present invention provides an anomaly early warning method for verifying the status of power grid equipment tagging / untagged in a centralized control system, the method comprising: The system acquires the equipment status information and tagging status of the primary equipment intervals within the centralized control system; the equipment status information includes remote signaling location data, remote measurement data, and electrical topology data. The pre-built location criteria, measurement criteria, and topology criteria are invoked, and the actual operating status of the primary equipment interval is comprehensively determined based on the location criteria, measurement criteria, and topology criteria. By comparing the actual operating status with the listing status, inconsistencies in status are identified. Based on the identified inconsistencies in the status, corresponding delisting warning information or listing reminder information is generated and pushed.

[0008] Furthermore, the location criterion is a criterion rule for determining whether the primary equipment bay is in operation, hot standby, cold standby, or maintenance state based on the remote signaling location data; wherein, the remote signaling location data includes the remote signaling status of circuit breakers, disconnectors, and grounding switches within the primary equipment bay; The measurement criterion is a rule for determining whether the primary equipment interval is in a energized state based on the comparison between the telemetry measurement data and a preset zero drift threshold; wherein, the telemetry measurement data includes current or voltage telemetry measurement values ​​associated with the primary equipment interval. The topology criterion is a rule for determining whether the primary equipment bay is in a energized state based on power grid topology analysis of the electrical topology data.

[0009] Furthermore, the actual operating status of the primary equipment interval is determined comprehensively based on the location criteria, measurement criteria, and topology criteria, including: If both the topology criterion and the measurement criterion indicate that the primary equipment interval is in a power outage state, and the location criterion indicates that the primary equipment interval is in a maintenance state, then the actual operating state is determined to be a maintenance state. If both the topology criterion and the measurement criterion indicate that the primary equipment interval is in a power outage state, and the location criterion indicates that the primary equipment interval is in a hot standby state, then the actual operating state is determined to be a hot standby state. If the topology criterion, measurement criterion, and location criterion all indicate that the primary equipment interval is in a power outage state or a cold standby state, then the actual operating state is determined to be a cold standby state. If at least one of the topology criteria, measurement criteria, and location criteria indicates that the primary equipment interval is in a energized or operating state, then the actual operating state is determined to be an energized operating state.

[0010] Furthermore, the displayed status includes maintenance signs, power outage signs, not in operation signs, power supply guarantee signs, commissioning signs, prohibition of closing signs, and prohibition of opening signs; based on the comparison between the actual operating status and the displayed status, inconsistencies are identified, which include at least one of the following four categories: The first type of inconsistent status is: the actual operating status is energized or hot standby, but the listed status is maintenance sign or power outage sign; The second type of inconsistent status is: the actual operating status is hot standby or cold standby, but the listed status is a power supply guarantee sign. The third type of inconsistent status is when the actual closing or opening status of the circuit breaker in the primary equipment bay conflicts with the requirement that the sign should be a prohibition sign for closing or opening. The fourth type of inconsistent status is when the actual operating status is in cold standby or maintenance status, and the listed status is not a power outage sign or maintenance sign.

[0011] Furthermore, the step of generating and pushing corresponding delisting warning information or listing reminder information based on the identified inconsistencies in the status includes: For the first type of inconsistent status, the second type of inconsistent status, and the third type of inconsistent status, generate and push the delisting warning information to remind the operation and maintenance personnel to perform the delisting operation; For the identified fourth type of inconsistent status, a configurable delay timer is started. If the primary equipment interval is still in cold standby or maintenance status after the delay ends, and the tag status is still not a power outage sign or maintenance sign, then the tag reminder information is generated and pushed to remind the operation and maintenance personnel to perform the tagging operation.

[0012] Furthermore, if the tagging status of the primary equipment interval is detected as a debugging tag, the tagging status verification of the primary equipment interval is skipped.

[0013] Furthermore, the methods for pushing the delisting warning information include: The delisting warning information is pushed to one or more workstation nodes through the message bus of the centralized control system. The warning information is presented in the form of a pop-up window on the workstation interface. The pop-up window content includes the substation name, the name of the primary equipment bay, the actual operating status, the labeling status, and suggested operations.

[0014] Furthermore, the triggering conditions for obtaining the device status information include: During the initialization of the centralized control system; When the centralized control system is operating normally, it receives the position change information of the circuit breaker or disconnector within the primary equipment bay. Secondly, the present invention also provides an abnormal early warning system for power grid equipment tagging status verification based on the centralized control system, characterized in that the system includes: The status acquisition module is configured to acquire the equipment status information and tagging status of the primary equipment intervals within the centralized control system; the equipment status information includes remote signaling location data, remote measurement data, and electrical topology data. The criterion invocation module is configured to invoke pre-built location criteria, measurement criteria, and topology criteria. The status judgment module is configured to: comprehensively judge the actual operating status of the primary equipment interval based on the position criterion, measurement criterion, and topology criterion; The consistency verification module is configured to: compare the actual operating status and the listing status to identify inconsistencies in the status; The early warning generation module is configured to generate and push corresponding delisting early warning information or listing reminder information based on the identified inconsistent status situations.

[0015] Thirdly, the present invention also provides a computer device, comprising: Memory, used to store computer programs / instructions; A processor is used to execute the computer program / instructions to implement the abnormal early warning method for the verification of the status of power grid equipment tagging and untagged based on a centralized control system, as described in any one of claims 1 to 8.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. This invention acquires the equipment status information and tagging status of primary equipment intervals within a centralized control system, constructs location criteria, measurement criteria, and topology criteria, and performs comprehensive judgment by integrating multiple source criteria, overcoming the misjudgment that may be caused by a single information source, and providing accurate status basis for subsequent tagging verification; in addition, it transforms manual verification into automatic system monitoring and intelligent reminders, covering multiple links such as tagging, tag removal, and status anomalies, significantly reducing tagging and tag removal errors caused by forgetfulness, negligence, etc., and realizing closed-loop management of tagging and tag removal operations.

[0017] 2. This invention, through real-time automatic verification of the status of the tagging equipment, can immediately detect and warn of dangerous situations such as "operation with tag" and "operation conflicting with prohibition signs," effectively preventing safety accidents caused by inconsistent status. Simultaneously, the delayed judgment mechanism introduced for "missed tagging" avoids false alarms caused by momentary disturbances, further improving the accuracy and reliability of the warning information.

[0019] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0020] The term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Example 1

[0021] See Figure 1 This embodiment provides an anomaly early warning method for verifying the status of power grid equipment tagging and removal based on a centralized control system. The method proposed in this invention runs in a new generation of substation centralized monitoring system (centralized control system). This system is typically divided into Security Zone I / II and Security Zone IV in terms of hardware, and deploys application servers, database servers, and workstations. The method proposed in this invention is mainly implemented by the "Intelligent Tag Removal and Removal Reminder Service" module deployed on the application server in Security Zone I / II, and interacts with the user interface deployed on the workstation through the "Intelligent Pop-up Service" module. Data interaction relies on basic interfaces provided by the platform, such as real-time database, historical database, message bus, and file services.

[0022] The specific steps for implementing the method are as follows; Step S1: Obtain the equipment status information and tagging status of the primary equipment interval within the centralized control system; the equipment status information includes remote signaling location data, remote measurement data, and electrical topology data; As a specific embodiment, during the initialization of the centralized control system, the system retrieves the equipment status information and tagging status of all primary equipment bays containing circuit breakers from the real-time database and processes them in batches. The equipment status information includes remote signaling location data, remote measurement data, and electrical topology data. Specifically, the remote signaling location data includes the remote signaling status of circuit breakers, disconnectors, and grounding switches; the remote measurement data includes the remote measurement values ​​of primary equipment bay current and line voltage.

[0023] The status of the signs includes maintenance signs, power outage signs, not in operation signs, power supply guarantee signs, commissioning signs, prohibition of closing signs, and prohibition of opening signs.

[0024] During normal system operation, upon receiving the change information of a circuit breaker or disconnector, the system triggers real-time processing of the primary equipment bay to which it belongs, obtains the real-time equipment status information and tagging status of the primary equipment bay, and performs subsequent status judgment and consistency verification.

[0025] Step S2: Invoke the pre-built position criteria, measurement criteria, and topology criteria, and comprehensively determine the actual operating status of the primary equipment interval based on the position criteria, measurement criteria, and topology criteria; 1. The location criterion is based on remote signaling location data to determine whether a primary equipment bay is in operation, hot standby, cold standby, or under maintenance. The remote signaling location data includes the remote signaling status of circuit breakers, disconnectors, and grounding switches within the primary equipment bay. Specifically: If the circuit breaker in the primary equipment bay is in the closed position, at least one of the disconnecting switches connected on both sides of the circuit breaker is in the closed position, and all grounding switches are in the open position, then the primary equipment bay is determined to be in operation. If the circuit breaker in the primary equipment bay is in the open position, at least one of the disconnecting switches connected on both sides of the circuit breaker is in the closed position, and all grounding switches are in the open position, then the primary equipment bay is determined to be in hot standby mode. If all circuit breakers and disconnectors in the primary equipment bay are in the open position, and all grounding switches are in the open position, then the primary equipment bay is considered to be in cold standby mode. If all circuit breakers and disconnectors in a primary equipment bay are in the open position, and a grounding switch is in the closed position, then the primary equipment bay is considered to be under maintenance.

[0026] 2. The measurement criterion is a rule for determining whether a primary equipment interval is energized, based on a comparison between telemetry data and a preset zero-drift threshold; wherein, the telemetry data includes current or voltage telemetry values ​​associated with the primary equipment interval. Specifically: The preset zero drift threshold is set to 0.5% of the rated value, and the voltage threshold is set to 10% of the rated voltage. The system acquires the telemetry values ​​of the primary equipment interval current or line voltage in real time. If the telemetry values ​​of current or voltage exceed the corresponding threshold, the primary equipment interval is determined to be in a live state; otherwise, if both are below the threshold, it is determined to be in a power outage state.

[0027] To further improve the accuracy of the criteria and avoid misjudgments caused by differences in equipment characteristics or changes in operating conditions, the zero drift threshold and voltage threshold can be dynamically adjusted according to the equipment type (such as the primary equipment bay of the main transformer or the primary equipment bay of the line) and real-time operating conditions (such as peak load period or off-peak period).

[0028] 3. The topology criterion is a set of rules for determining whether a primary equipment bay is energized based on power grid topology analysis of electrical topology data. Specifically: Obtain the energized status results of the electrical island to which the device belongs, provided by the centralized control system topology analysis service. An electrical island refers to a group of electrical devices connected together by switching equipment and having the same energized state. If the electrical island is energized, the device is determined to be likely energized; otherwise, it is determined to be de-energized.

[0029] This invention integrates remote signaling location data, telemetry measurement data, and electrical topology analysis results to make a multi-dimensional comprehensive judgment on the actual operating status of equipment. Compared with traditional methods that rely on a single information source, this comprehensive judgment mechanism can more comprehensively and accurately reflect the true operating condition of the equipment, effectively avoiding misjudgments caused by single information anomalies such as remote signaling contact jitter, telemetry zero drift error, or topology model update delay, and significantly improving the reliability and robustness of equipment status perception.

[0030] The logic for comprehensive judgment is as follows: if both the topology criterion and the measurement criterion indicate that the primary equipment interval is in a power outage state, and the location criterion indicates that the primary equipment interval is in a maintenance state, then the actual operating state is determined to be a maintenance state. If both the topology criterion and the measurement criterion indicate that the primary equipment interval is in a power outage state, and the location criterion indicates that the primary equipment interval is in a hot standby state, then the actual operating state is determined to be a hot standby state. If the topology criterion, measurement criterion, and location criterion all indicate that the primary equipment interval is in a power outage state or a cold standby state, then the actual operating state is determined to be a cold standby state. If at least one of the topology criteria, measurement criteria, and location criteria indicates that the primary equipment bay is in a energized or operating state, then the actual operating state is determined to be an energized operating state.

[0031] Step S3: Compare the actual operating status and the listing status to identify inconsistencies. State inconsistency situations include at least one of the following four categories: The first type of inconsistent status is: the actual operating status is live or hot standby, but the tagged status is maintenance sign or power outage sign; The second type of inconsistent status is: the actual operating status is hot standby or cold standby, but the status displayed is a power supply guarantee sign. The third type of inconsistent status is when the actual closing or opening status of the circuit breaker in the primary equipment bay conflicts with the requirement that the sign should be a prohibition sign for closing or opening. The fourth type of inconsistent status is when the actual operating status is cold standby or maintenance status, and the status displayed is not a power outage sign or maintenance sign.

[0032] If the tagging status of a single equipment interval is detected as a debugging sign, then skip the tagging status verification for that single equipment interval.

[0033] Step S4: Based on the identified inconsistencies in the status, generate and push corresponding delisting warning information or listing reminder information.

[0034] Specifically, this step is implemented through the "Intelligent Tag Removal Reminder Service" module: For the identified first, second, and third types of inconsistencies, a tag removal warning message is generated and pushed to remind maintenance personnel to perform the tag removal operation. The push of the tag removal warning message is implemented through the "Intelligent Pop-up Service" module, and the push methods include: The delisting warning information is pushed to one or more workstation nodes through the message bus of the centralized control system; The warning information is displayed as a pop-up window on the workstation interface. The pop-up includes the substation name, primary equipment bay name, actual operating status, tag status, and suggested actions. The format of the warning message is: "The XX primary equipment bay in XX substation is currently in XX status and has the XX tag attached. Please confirm whether the current operating status of the equipment is correct. If normal, please remove the tag." The pop-up usually uses a prominent color (such as a red background) and is accompanied by an audio prompt to ensure that maintenance personnel can notice the warning information promptly.

[0035] For the identified fourth type of inconsistent status, a configurable delay timer is activated. If, after the delay, the primary equipment interval is still in cold standby or maintenance status, and the tag status is still not a power outage or maintenance tag, a tagging reminder message is generated and pushed to remind maintenance personnel to perform the tagging operation. The duration of the delay timer is a configurable parameter. As a specific implementation plan, the delay timer duration is set to 5 minutes, which can be adjusted according to actual maintenance needs. The purpose of setting the delay mechanism is to avoid false alarms caused by momentary faults, short-term operations, or status fluctuations. For example, if a line trips due to a momentary fault and then automatically recloses successfully, pushing a tagging reminder directly without a delay would cause unnecessary interference.

[0036] If, after the delay period, the primary equipment bay remains in a cold standby or maintenance state and no power outage or maintenance sign is posted, the system will generate a sign posting reminder message. The reminder message will be formatted as: "The primary equipment bay of substation XX is currently in state XX. Please confirm whether a sign needs to be posted." Example 2
