Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to an automatic identification system and method for switch position changes. Background Technology

[0002] To reduce the risk of workers accidentally touching operating equipment at substation construction sites, maintenance keys are provided. These keys are equipped with anti-misoperation interlocking functions, allowing only the switches to be operated for maintenance. However, in reality, some workers, seeking convenience and taking chances, illegally use short-circuit wires to unlock equipment, leading to accidental contact with the output circuit and causing switch tripping.

[0003] Currently, the method for checking whether substation construction workers use maintenance keys during switch opening and closing involves supervisory personnel standing on-site to observe whether workers are using jumper wires improperly. This manual supervision method is costly, inefficient, and unreliable. Therefore, developing an automated system to monitor whether substation construction workers are using maintenance keys during switch opening and closing, thereby addressing the technical problems of high cost, low efficiency, and low reliability associated with manual supervision, is a pressing technical issue that needs to be addressed by those skilled in the art.

[0041] For easier understanding, please refer to Figure 1This invention provides an embodiment of an automatic switch position identification system, including an automated office platform, an intelligent supervision system, a data security master station, an automated remote operation and maintenance master station, an OCS system, and a DICP system;

[0042] The automated office platform connects to the intelligent supervision system via a firewall;

[0043] The intelligent supervision system connects to the main web server of the security information system, the web server of the automated remote operation and maintenance system, the web server of the OCS system, and the web server of the DICP system through firewalls respectively.

[0044] The DICP system connects to the OCS system via a firewall;

[0045] The DICP system is used to create and issue operation tickets and to save the operation records of dispatchers or operators;

[0046] The OCS system is used to monitor the primary and secondary equipment of substations;

[0047] The automated remote operation and maintenance master station is used to remotely monitor the information of the five-proof monitoring machine, which is used in conjunction with the maintenance key.

[0048] The main data collection station is used to collect data from protection devices.

[0049] The intelligent monitoring system is used to monitor the switching status of substation switches, analyze the causes of switching status changes, and publish the analysis results through an automated office platform.

[0050] It should be noted that the automated office platform is used to publish the results of switch displacement cause analysis in document format. The automated office platform is the Elink office system. The Elink office system refers to a dedicated office information transmission system for the power grid.

[0051] Primary equipment refers to substation equipment such as switches, disconnectors, and grounding switches.

[0052] Secondary equipment refers to protection equipment, safety and automatic equipment, etc.

[0053] The maintenance key is a device used to prevent misoperation and is applied at substation construction sites. The five-prevention monitoring unit works in conjunction with the maintenance key, controlling equipment operation through logical judgment and the correctness of operating procedures, allowing only the switches under maintenance to be opened or closed.

[0054] The Baoxin master station web server connects to the Baoxin master station via forward and reverse isolation devices. The automated remote operation and maintenance master station web server connects to the automated remote operation and maintenance master station via forward and reverse isolation devices. The OCS system web server connects to the OCS system via forward and reverse isolation devices. The DICP system web server connects to the DICP system via forward and reverse isolation devices.

[0055] The working principle of the automatic switch position recognition system provided in this invention is as follows:

[0056] The Baoxin master station collects data from protection devices; the DICP system issues operation tickets and obtains operation records from dispatchers or operators; the OCS system monitors and controls primary and secondary equipment in the substation; the automated remote operation and maintenance master station monitors information from the five-prevention monitoring machine and the use of maintenance keys; the intelligent supervision system obtains the substation switch position change status through the OCS system; based on the substation switch position change status, and according to the data from the DICP system, Baoxin master station, and automated remote operation and maintenance master station, analyzes the causes of substation switch position changes; and publishes the analysis results through the automated office platform, allowing supervisors to obtain the analysis results of substation switch position change causes through the automated office platform.

[0057] Specifically, the intelligent supervision system is used for:

[0058] Receive switch position remote signaling signals issued by the OCS system;

[0059] Determine whether the switch is under maintenance based on the switch position change remote signaling signal;

[0060] If the switch is under maintenance, the cause of the switch change is identified through the main web server of the security information system and the automated remote operation and maintenance main web server. It is determined whether the change is due to a test signal from maintenance personnel or the failure to use the maintenance key. The result is then published through the automated office platform. In specific implementation, if the switch is under maintenance, the action information of the protection device is obtained through the main web server of the security information system. Based on this information, it is determined whether the protection device has activated. If it has, the cause of the switch change is determined to be a test signal from maintenance personnel, and the result is published through the automated office platform. If not, the information from the five-proof monitoring machine is obtained through the automated remote operation and maintenance main web server. Based on this information, it is determined whether there is a record of the maintenance key being used. If there is, the cause of the switch change is determined to be a test signal from maintenance personnel, and the result is published through the automated office platform. If there is no record of the maintenance key being used, the cause of the switch change is determined to be the failure to use the maintenance key, and the result is published through the automated office platform.

[0061] After the maintenance key is used, the usage record will be sent back to the five-prevention monitoring machine. The intelligent supervision system can retrieve the relevant logs of the five-prevention monitoring machine of the substation where the switch is located through the automated remote operation and maintenance master station, and can intelligently identify whether there is a maintenance key usage record at the time of the switch change.

[0062] If the switch is not under maintenance, the DICP system web server identifies the cause of the switch change, determining whether it's due to operator or operator action causing a tripped protection device, or an abnormal change. The result is then published through the automated office platform. In specific implementation, if the switch is not under maintenance, the DICP system web server retrieves data from the DICP system. Based on this data, it checks for operator or operator activity records. If so, the cause is determined to be operator or operator action, and the result is published through the automated office platform. If not, the protection device's action information is retrieved from the main security information web server. Based on this information, it's determined whether the protection device has activated. If activated, the cause is determined to be a tripped protection device, and the result is published through the automated office platform. If not activated, the cause is determined to be an abnormal change, and the result is published through the automated office platform.

[0063] In one embodiment, the circuit network security partition is divided into power network security zone I, power network security zone II, power network security zone III, and power network security zone IV. The automated office platform is deployed in power network security zone IV, the intelligent monitoring system is deployed in power network security zone III, the DICP system is deployed in power network security zone II, and the security information master station, the automated remote operation and maintenance master station, and the OCS system are deployed in power network security zone I.

[0064] In one embodiment, the main station for information protection is connected to the substation via a dispatch data network. The substation is deployed at the substation and connected to the protection device. The automated remote maintenance main station is connected to the automated remote maintenance terminal via a dispatch data network. The automated remote maintenance terminal is connected to the five-proof monitoring machine. The OCS system is connected to the remote control unit via a dispatch data network. The remote control unit is connected to the measurement and control device, which is used to measure and control the primary and secondary equipment of the substation. The automated remote maintenance main station can remotely collect real-time information from the five-proof monitoring machine. The five-proof monitoring machine is deployed at the substation and is used to monitor and control the primary and secondary equipment within the substation. It can be used for key unlocking during maintenance, archiving usage records, etc.

[0065] In one embodiment, the protection master station is also connected to a waveform recorder. The waveform recorder is used to record fault waveform data. When identifying the cause of switch position change through the protection master station web server and the automated remote operation and maintenance master station web server, the fault waveform data from the waveform recorder can be used for auxiliary judgment. The fault waveform data can be used to determine whether the protection device operates correctly. For example, if the fault waveform data shows that a fault has occurred, the protection device should operate.

[0066] The automatic switch change identification system provided by this invention includes an automated office platform, a smart supervision system, a protection and information master station, an automated remote operation and maintenance master station, an OCS system, and a DICP system. The protection and information master station collects data from protection devices; the DICP system obtains operation records from dispatchers or operators; the OCS system monitors and controls primary and secondary equipment in the substation; the automated remote operation and maintenance master station monitors information from the five-prevention monitoring machine and the use of maintenance keys; and the smart supervision system analyzes the causes of substation switch changes based on the switch change status and publishes the analysis results through the automated office platform. This system enables automatic analysis of the causes of substation switch changes and publishes the analysis results to supervisors through the automated office platform, achieving fully automated supervision. It solves the technical problems of high cost, low efficiency, and low reliability associated with manual supervision of substation construction personnel's use of maintenance keys during switch opening and closing.

[0067] For easier understanding, please refer to Figure 2 and Figure 3 This invention provides an automatic switch change identification method applied to the automatic switch change identification system provided in this invention, comprising:

[0068] Step 101: The intelligent monitoring system receives the switch change remote signaling signal issued by the OCS system through the OCS system web server.

[0069] It should be noted that the OCS system monitors the primary and secondary equipment of the substation. When a switch changes position, it sends a switch change remote signaling signal to the OCS system web server. The intelligent monitoring system receives the switch change remote signaling signal issued by the OCS system through the OCS system web server.

[0070] Step 102: The intelligent monitoring system determines whether the switch is under maintenance based on the switch position change remote signaling signal.

[0071] It should be noted that the intelligent monitoring system determines whether the switch is under maintenance based on the switch position change remote signal. If yes, step 103 is executed; otherwise, step 104 is executed. The maintenance status of the switch is identified by the maintenance sign hanging in the OCS system, or by the open position of the disconnect switches on both sides of the switch.

[0072] Step 103: If the switch is under maintenance, the intelligent monitoring system identifies the cause of the switch change through the main web server of the security information system and the web server of the automated remote operation and maintenance system. It determines whether the cause of the switch change is a test signal by maintenance personnel or an operation without the use of the maintenance key, and publishes the determination result through the automated office platform.

[0073] It should be noted that, as Figure 3 As shown, if the switch is in maintenance mode, the action information of the protection device is obtained through the main web server of the security information system. Based on the action information of the protection device, it is determined whether the protection device has been activated. If so, it is determined that the switch change is caused by a test signal from maintenance personnel, and the determination result is published through the automated office platform. If not, the information of the five-proof monitoring machine is obtained through the automated remote operation and maintenance main web server. Based on the information of the five-proof monitoring machine, it is determined whether there is a record of the use of the maintenance key. If there is a record of the use of the maintenance key, it is determined that the switch change is caused by a test signal from maintenance personnel, and the determination result is published through the automated office platform. If there is no record of the use of the maintenance key, it is determined that the switch change was not operated using the maintenance key, and the determination result is published through the automated office platform.

[0074] After the maintenance key is used, the usage record will be sent back to the five-prevention monitoring machine. The intelligent supervision system can retrieve the relevant logs of the five-prevention monitoring machine of the substation where the switch is located through the automated remote operation and maintenance master station, and can intelligently identify whether there is a maintenance key usage record at the time of the switch change.

[0075] Step 104: If the switch is not under maintenance, the intelligent monitoring system identifies the cause of the switch change through the DICP system web server, determines whether the switch change is due to the dispatcher or operator operating the switch, the protection device tripping, or an abnormal change, and publishes the judgment result through the automated office platform.

[0076] It should be noted that, as Figure 3 As shown, if the switch is not in maintenance mode, data from the DICP system is obtained through the DICP system web server. Based on this data, it is determined whether there are any operation records from dispatchers or operators. If so, the cause of the switch change is determined to be operation by dispatchers or operators, and the result is published through the automated office platform. If not, the action information of the protection device is obtained through the main security information web server. Based on this information, it is determined whether the protection device has activated. If the protection device has activated, the cause of the switch change is determined to be protection device tripping, and the result is published through the automated office platform. If the protection device has not activated, the cause of the switch change is determined to be abnormal, and the result is published through the automated office platform. Abnormal switch changes may be caused by unauthorized switch tripping, accidental contact by maintenance personnel, etc.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.
