Description

Technical Field

[0001] The present invention relates to the technical field of automatic acceptance of data signals of a centralized monitoring system of a substation, and in particular to a method and system for automatic acceptance of data signals of a new generation centralized control system of a substation. Background Art

[0002] In recent years, State Grid Corporation of China's substations have grown rapidly, significantly increasing the scale of its equipment. Consequently, the workload for monitoring personnel in basic signal acceptance has also increased. However, most substations utilize a centralized monitoring model, where station-side signals must be uploaded to a master station for centralized monitoring. Consequently, the requirements for the joint commissioning and acceptance of station-side and master-side signals have become increasingly stringent, requiring coordination between monitoring personnel and substation field personnel. Field personnel individually apply signal measurements for monitoring, while monitoring personnel monitor and confirm the results before completing the acceptance. However, there is often a one-to-many relationship between station-side and master stations, requiring multiple commissioning sessions at the station. This results in a high overall workload and a short timeframe, placing significant pressure on commissioning personnel and increasing uncertainty in the quality and efficiency of commissioning.

[0003] In order to solve and improve the verification methods of existing monitoring information and speed up the access of substation equipment monitoring information to the centralized control system in a direct acquisition and direct transmission manner, reduce the risk of information omissions and information errors in manual acceptance and verification, ensure the quality and efficiency of information joint commissioning and acceptance, and comprehensively improve the work efficiency of the master station's centralized monitoring of substations, according to the "Technical Specifications for Automatic Acceptance of Substation Monitoring Information" (Power Grid Operation

[2020] No. 88), the Equipment Department, together with the Provincial Control Center, has formulated a fully automatic acceptance plan for the telesignaling, telemetering, remote control, and teleadjustment of the substation telemotor expansion centralized control system link. Summary of the Invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problem solved by the present invention is that the existing data signal acceptance mechanism of the substation centralized control system has problems such as excessive personnel pressure, insufficiently refined acceptance mechanism, low acceptance efficiency, and low debugging quality.

[0006] (1) Excessive staff pressure: The existing acceptance work requires the cooperation of monitoring personnel and substation personnel. The on-site personnel apply the signal quantity to the monitored measurement one by one, and the monitoring personnel monitor and confirm to complete the acceptance. It is highly dependent on personnel, and there is a one-to-many situation between the station end and the master station. Multiple debugging of the station end is required. The overall debugging workload is large and the time is short, which puts a lot of pressure on the debugging personnel.

[0007] (2) The acceptance mechanism is not sophisticated enough: The existing acceptance mechanism is based on monitoring information while debugging and acceptance, and acceptance is carried out after problems are found and rectified. There is no clear distinction and refinement in the acceptance route of the signal, which is not flexible enough.

[0008] (3) Low acceptance efficiency: Over-reliance on manual debugging and acceptance. When there are many data signals and the acceptance work is heavy, manual debugging and verification are required repeatedly, which seriously reduces the acceptance efficiency.

[0009] (4) Low debugging quality: As part of the entire substation information access work, the signal coordination work between the station end and the master station usually needs to be completed and accepted in a short time. The acceptance workload is large, and human errors are prone to occur, resulting in low debugging quality.

[0010] To solve the above technical problems, the present invention provides the following technical solutions: a new generation substation centralized control system data signal automatic acceptance method, comprising: establishing a communication link between the automatic acceptance device and the substation system.

[0011] An acceptance sequence list is formulated according to the communication link, and the telesignaling, remote control, remote adjustment and remote motor telesignaling and telemetry data are compared according to the sequence list.

[0012] Establish telemetry model ID comparison relationships and perform measurement comparisons based on the relationships.

[0013] Store all comparison results and generate an acceptance report.

[0014] As a preferred solution of the method for automatic acceptance of data signals of the new generation substation centralized control system described in the present invention, the establishment of a communication link between the automatic acceptance device and the substation system includes establishing communication links for telesignaling, remote control, remote adjustment and remote motor telemetry and remote adjustment.

[0015] The telesignaling communication link is automatic acceptance device-station remote motor-centralized control system-station dispatching data network switch-automatic acceptance device and automatic acceptance device-centralized control system.

[0016] The remote control and remote adjustment communication link is the in-station remote motor-debugging switch-automatic acceptance device.

[0017] The remote motor telemetry and telecontrol communication line is the mirror image of the old remote motor in the station - the new remote motor - the automatic acceptance device.

[0018] As an optimal solution for the automatic acceptance method of data signals of the new generation substation centralized control system described in the present invention, the communication link acceptance sequence table includes a remote signal acceptance sequence table, a remote control acceptance sequence table, a remote adjustment acceptance sequence table and a remote motor telemetry and remote adjustment acceptance sequence table.

[0019] As a preferred solution of the new generation substation centralized control system data signal automatic acceptance method described in the present invention, the remote signal acceptance sequence table includes the remote signal fully automatic acceptance-new centralized control forwarding table and the remote signal fully automatic acceptance-centralized control and dispatching shared forwarding table.

[0020] Automatic acceptance of telesignaling - the newly added centralized control transfer table compares the information point number, interval name, standard name and telesignaling value of the automatic acceptance device for receiving and sending telesignals, verifies whether the telesignaling of the centralized control system and the substation is consistent, and sends the acceptance results to the centralized control system.

[0021] Fully automatic acceptance of telesignaling - the centralized control and dispatching share a common transfer table to compare the information point number, interval name, standard name and telesignaling value of the automatic acceptance device for receiving and sending telesignals, verify whether the telesignals of the centralized control system and the substation are consistent, and send the acceptance results to the centralized control system.

[0022] The remote control acceptance sequence table is sent by the control system and the centralized control system to the station end respectively. The remote control object acceptance is completed by comparing the consistency of the messages with the same remote control point number.

[0023] The remote control acceptance sequence table is composed of the control system and the centralized control system sending remote control preset commands to the station end respectively, and completing the remote control object acceptance by comparing the consistency of the messages with the same remote control point number.

[0024] The remote motor telemetry and telecontrol acceptance sequence table uses the automatic acceptance device to check the consistency of the new and old remote motor forwarding information, and complete the acceptance of the correctness of the telesignaling and telemetry forwarding information configuration of the new remote motor in the station.

[0025] As a preferred solution of the method for automatic acceptance of data signals of the new generation substation centralized control system described in the present invention, the establishment of a telemetry model ID comparison relationship and the measurement comparison based on the relationship include obtaining section files of the same plant and station and the same time of the centralized control system and the control system, establishing a model ID comparison relationship, setting a threshold through the comparison relationship, initiating a comparison task, performing multiple rounds of comparison according to the model ID comparison relationship, generating a measurement comparison report, and storing the comparison report in the centralized control system.

[0026] As a preferred solution of the method for automatic acceptance of data signals of the new generation substation centralized control system described in the present invention, the remote control object acceptance step includes confirming the acceptance environment, accepting the substation remote motor A and accepting the substation remote motor B.

[0027] The steps to confirm the acceptance environment are:

[0028] The acceptance system automatically confirms the acceptance of the remote control transfer table for the station's remote motors, confirms that communication between the control system, centralized control system, and the station's remote motors is normal, confirms that the automatic acceptance device has correctly received the remote motor mirror message, confirms that the centralized control system has completed the graphic model maintenance work for the substation to be accepted, and establishes a remote control acceptance sequence. The first remote control verification is performed by performing remote control preset operations one by one on the control system and centralized control system operation interface. The second verification uses batch remote control presets in the centralized control system to confirm that no planned maintenance operations have been performed on the accepted substation. After the automatic acceptance is completed, the acceptance system automatically extracts the remote device control quantity from the centralized control system for actual remote control operation verification.

[0029] The steps for verifying the substation remote motor A are:

[0030] Connect the debugging switch. The acceptance system automatically confirms that the control system is operating on remote unit B. Connect the mirror switch in series between remote unit A and the switch on the station control layer A network. Connect the automatic acceptance device of the control master station to the mirror port of the mirror switch. Switch the control system to remote unit A. After confirming that the data of remote unit A on the control master station is normal, switch both the centralized control system and the control master station to remote unit A.

[0031] Acceptance of remote adjustment points: The acceptance system automatically initiates remote presets one by one according to the remote adjustment sequence list, and the automatic acceptance device generates a remote adjustment acceptance reference file. The centralized control system automatically initiates remote presets one by one according to the remote adjustment sequence list, and the automatic acceptance device generates a remote adjustment acceptance verification file. The automatic acceptance device compares the reference file with the verification verification file to generate a remote adjustment acceptance report. During the acceptance of a single remote adjustment point, manual reconfirmation is performed for any abnormal remote adjustment points.

[0032] Restore remote motor A: The acceptance system automatically confirms that the control system is operating on remote motor B. Remove the debugging switch. Confirm that the control system is operating on remote motor A and the data is normal.

[0033] The steps for acceptance of substation remote motor B are:

[0034] Connect the debugging switch. The acceptance system automatically confirms that the control system is operating on remote unit B. Connect the mirror switch in series between remote unit B and the switch on the station control layer B network. Connect the automatic acceptance device to the mirror port of the mirror switch. Switch the centralized control system to remote unit B. Switch the centralized control system to remote unit B and confirm that the data is normal.

[0035] Acceptance of remote adjustment points: The central control system sends batches of remote adjustment preset commands according to the remote adjustment sequence list to the control master station, generating a verification file. The automatic acceptance device compares the reference file with the verification file to generate a remote adjustment acceptance report. The remote adjustment points are accepted, and any abnormal remote adjustment points undergo manual reconfirmation.

[0036] Restore remote motor B: Confirm that the control system is working on remote motor A and remove the debugging switch. Confirm that the control system is working on remote motor B and the data is normal.

[0037] As a preferred solution of the method for automatic acceptance of data signals of the new generation substation centralized control system described in the present invention, the steps for accepting the correctness of the configuration of the telecontroller telesignaling and telemetry forwarding information include confirming the acceptance environment and acceptance conditions, and accepting the new telecontrollers A and B of the substation.

[0038] The steps to confirm the acceptance environment and acceptance conditions are:

[0039] For smart substations, SCD and RCD files are provided. For devices using serial communication and without protocol conversion, manual signal verification is performed.

[0040] The acceptance of new remote motors A and B in substations includes on-site acceptance and joint acceptance of master and substations.

[0041] The on-site acceptance steps are:

[0042] The acceptance system is configured with remote motors A and B. The mirror background manufacturer provides the same model device as the remote motor in the station, and imports the configuration of remote motors A and B in the station to form a remote motor mirror.

[0043] The acceptance system sets up a test environment. The old remote motor A and B mirror images and the new remote motor A and B station control layer interface are connected to the automatic acceptance device signal trigger simulation interface. The old remote motor A and B mirror images and the new remote motor A and B data dispatch network interface are connected to the automatic acceptance device master station simulation network port, forming a closed loop.

[0044] The automatic acceptance device begins simulating bay-layer equipment and begins sending telesignaling and telemetering signals in the order of the point table. The automatic acceptance device automatically compares the consistency of the old remote motors A and B mirror images and the new remote motors A and B forwarding master station information, completes the correctness verification of the new remote motors A and B telesignaling and telemetering forwarding configuration, and forms an acceptance conclusion.

[0045] For abnormal telesignaling and telemetering points, use the steps of setting up the test environment to perform single-point triggering.

[0046] After the acceptance of the new remote motors A and B is completed, the channel links of the new remote motors A and B in the station are restored, and the data of the remote motors A and B at the control master station and the centralized control master station are verified to be correct.

[0047] The steps for joint acceptance of master and substations are as follows:

[0048] The data dispatch network interface of Xinyuan motors A and B is connected to the centralized control master station, and the station control layer interface is connected to the telesignaling and telemetry signal triggering interface of the automatic acceptance device.

[0049] The data communication gateway in the station opens a temporary network port for telesignaling and telemetering closed-loop acceptance, and is connected to the automatic acceptance device.

[0050] Use the automatic acceptance device to start simulating the bay layer equipment, and send the telesignaling and telemetering points in the order of the information sequence list. The automatic acceptance device forms an acceptance conclusion by comparing the sent and received telesignaling and telemetering information for consistency.

[0051] For abnormal telesignaling points, they can be compared again using the automatic acceptance device after confirmation.

[0052] After the acceptance of Xinyuan motors A and B is completed, the network between Xinyuan motors A and B and the station control layer is restored, and the data is confirmed to be normal with the main station system.

[0053] The storing of all comparison results and generating an acceptance report includes storing the acceptance results of telesignaling, remote control, remote adjustment and remote motor telesignaling and telemetry and the comparison results of telemetry in the centralized control system and generating an acceptance report.

[0054] A new generation of automatic data signal acceptance system for substation centralized control system, characterized by: including:

[0055] Control master station adaptation module: It consists of a control master station, a centralized control master station, a dispatching data network, and a dispatching data network switch. It generates acceptance rules and tasks by importing substation rule point tables or comparison relationships, and accepts the signals of the rule point tables. It supports point tables, diagrams, and parameter adaptation of dispatching automation systems of all mainstream manufacturers.

[0056] The telecontrol adapter module consists of a telecontrol unit and a dispatch data network switch. By importing the SCD file, the network address of the telecontrol entry is obtained. By importing the RCD file, the telecontrol forwarding information is obtained. The adapter module supports point tables and communication adaptation for telecontrol systems from all major manufacturers.

[0057] Human-computer interaction module: By monitoring the background monitoring data signals, the changed telesignaling data, alarm events, telesignaling position changes, and telemetering over-limit events are confirmed on the human-computer interface.

[0058] Signal Simulation Module: Communicates with bay-layer devices, supports network and serial substation communication links, includes channel status monitoring, supports mainstream protocols, and features direct alarm protocol parsing and information analysis. It implements communication message monitoring, remote signal position change monitoring, and remote signal position change confirmation. It supports simultaneous multi-channel acceptance, parameter setting for various dispatch automation system types, and graphical communication simulation for different dispatch monitoring systems.

[0059] Automatic acceptance module: Through the automatic acceptance device, it automatically checks the acceptance data and records the data and important matters of the entire acceptance process and automatically generates an acceptance report.

[0060] A computer device includes a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the above method when executing the computer program.

[0061] A computer-readable storage medium stores a computer program, which implements the steps of the method described above when executed by a processor.

[0062] Beneficial effects of the present invention: This method targets four types of data signals, namely telesignaling, telemetering, remote control and remote adjustment, and uses basic functional modules such as the master station adaptation module, the remote motor adaptation module, the human-computer interaction module, the signal simulation module and the automatic acceptance module to construct different fully automatic acceptance technical routes. For newly built stations and expanded and renovated stations, by adding a centralized control transfer table, a link between the automatic acceptance device - the remote motor within the station - the centralized control system - the dispatching data network switch within the station - the automatic acceptance device is constructed to realize the fully automatic acceptance function. By finely distinguishing the signal categories and applying specific fully automatic acceptance modules, a more efficient, flexible and accurate acceptance work can be completed by adopting fully automatic acceptance of telesignaling, fully automatic acceptance of telemetering and fully automatic acceptance of remote control.

[0140] Step 4: Acceptance of single telesignaling and telemetering points. For abnormal telesignaling and telemetering points, the second step can be used to trigger single points.

[0141] Step 5: Restore communication between the new remote motors A and B. After the acceptance of the new remote motors A and B is completed, restore the channel links of the new remote motors A and B in the station and verify that the data of remote motors A and B in the control master station and the centralized control master station are correct.

[0142] Master-substation joint acceptance steps:

[0143] Step 1: Connect Xinyuan Motors A and B to the data dispatch network. The data dispatch network interfaces of Xinyuan Motors A and B are connected to the centralized control master station, and the station control layer interfaces are connected to the remote signal and telemetry signal trigger interfaces of the automatic acceptance device.

[0144] Step 2: The automatic acceptance device is connected to the automatic acceptance channel. The station's data communication gateway opens a temporary network port for telesignaling and telemetry closed-loop acceptance and connects it to the automatic acceptance device.

[0145] Step 3: Acceptance of telesignaling and telemetering points. Use the automatic acceptance device to simulate the bay layer equipment and send telesignaling and telemetering points in the order of the information sequence list. The automatic acceptance device forms an acceptance conclusion by comparing the sent and received telesignaling and telemetering information for consistency.

[0146] Step 4: Acceptance of single telesignaling and telemetering points. For abnormal telesignaling points, they can be compared again using the automatic acceptance device after confirmation.

[0147] Step 5: Complete the acceptance of the new remote motors A and B (whether to immediately replace the old remote motors A and B on duty). After the acceptance of the new remote motor A is completed, restore the network between the new remote motors A and B and the station control layer, and confirm with the master station system that the data is normal.

[0148] It should be noted that the following rules must be followed according to the fully automatic acceptance action plan for telesignaling, telemetering, remote control, remote adjustment and remote motor telesignaling and telemetering:

[0149] When received data is discontinuous, the data transmission link is checked. If a link is found to be broken, a blockchain-based link verification process is initiated. This blockchain technology ensures the integrity and transparency of data transmission while automatically identifying and isolating potential data tampering. If blockchain verification fails to restore the link, advanced network topology optimization algorithms are implemented to dynamically adjust the network structure and attempt to restore data flow through alternative paths. If the link check is normal but data is still lost, an adaptive network security defense mechanism is implemented to automatically adjust network security policies based on anomaly detection results to enhance data link protection.

[0150] If the link check is normal, analyze the possible areas of data packet loss and start local network packet capture. Based on the packet capture results, check the data processing performance of specific nodes or routes. If performance issues are found in specific nodes, try to optimize the route or increase the cache capacity.

[0151] If the link and node are functioning normally, a detailed diagnostic report will be automatically sent to the central control to request manual intervention.

[0152] When the accepted data exceeds the limit, a comparative analysis is performed based on historical data. If the historical data shows a similar trend, the degree of deviation between the exceeded data and the historical trend is calculated to determine whether it is within an acceptable range. If the deviation is large, a calculation algorithm is used for in-depth analysis to check whether there is external interference or equipment failure. Based on the analysis results, the threshold is adjusted or necessary maintenance is performed. If there is no similar historical trend, multi-dimensional data visualization technology is used to combine historical and real-time data to generate interactive data charts to provide more in-depth data limit analysis. Advanced pattern recognition algorithms are used to automatically analyze the potential factors behind data limit violations, such as equipment aging, environmental changes, or operational errors, and provide customized data correction suggestions. If the data limit violation is complex and it is difficult to determine the cause through conventional analysis, manual intervention is implemented to conduct in-depth diagnosis and interpretation of the complex data limit violation, implement predictive modeling of data limit violation patterns, and use advanced predictive analysis technology to predict possible data limit violations in the future and plan response measures in advance.

[0153] If the stability of the data received during acceptance is less than 70%, increase the number of acceptance tests. If stability improves to above 80% after the increase, analyze the key factors that improve stability and document the optimization strategy. Fine-tune the optimization strategy to adapt to similar scenarios in the future. Continuously monitor to ensure sustained stability. If the stability improvement does not reach above 80% after the increase, further analyze the reasons for the failure to meet expectations, including equipment issues or external interference. Based on the analysis results, adjust the acceptance strategy or equipment configuration. Increase data sampling points to obtain more information to assist in decision-making.

[0154] When a connection times out, the system checks the network configuration. If any errors are found, it automatically performs configuration verification and correction. If automatic correction fails, it records the details of the configuration error and prompts the operator. It also suggests possible repair steps, such as rolling back to the last stable configuration.

[0155] If the configuration is correct, a traceroute is performed to identify nodes with high latency. Further network diagnostics are performed on identified high-latency nodes. If the problem persists, an alternate route is automatically switched to, and maintenance personnel are notified.

[0156] When the acceptance data finds inconsistencies in telesignaling points, the AI ​​model is used to analyze historical behaviors. When it is identified as a false alarm, the adaptive learning mechanism is activated, and new data samples are promptly incorporated through incremental learning to continuously improve the accuracy and adaptability of the AI ​​model. If false alarms occur frequently, the interactive feedback system is activated to allow operators to directly mark false alarms, and these marks are fed back to the AI ​​model as immediate feedback to improve the model's discrimination ability. If it is identified as a potential problem, the judgment basis of the AI ​​model is recorded in detail for the engineer's reference. Possible problem solutions are provided to operators to reduce the difficulty of manual judgment. In the face of complex problems, a collaborative decision-making mechanism is implemented to combine AI models, operator experience and historical case libraries to jointly develop the best solution to ensure a comprehensive and accurate resolution of the problem.
