[0027] According to an embodiment of the present invention, a signal verification method for a substation is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0028] Figure 1 is a flowchart of a signal verification method for a substation according to an embodiment of the present invention. The method may include the following steps:

[0029] Step S101, obtain the configuration file of the substation.

[0030] In the technical solution provided in step S101 of the present invention above, the above-mentioned configuration file can be at least used to record the association relationship between devices in the substation and the communication signals between devices in the substation. For example, the above-mentioned configuration file can be a Substation Configuration Description (SCD for short) file. This is only an example here and is not specifically limited.

[0031] In this embodiment, the configuration file of the substation is obtained. Optionally, in this embodiment, by accessing the monitoring system of the substation, at least the association relationship between devices in the substation and the communication signals between devices in the substation can be obtained. This is only an example here and is not specifically limited.

[0032] Step S102: Determine the signal status of the event signal of the device based on the configuration file.

[0033] In the technical solution provided in step S102 of the present invention, the above event signal may be an electrical signal corresponding to an event occurring in the device. The above signal status may be used to indicate whether the event signal of the device is a normal signal or an abnormal signal. For example, the above event signal may be a GOOSE disconnection alarm signal, and the above signal status may be a normal signal status or an abnormal signal status. This is only an example here and is not specifically limited.

[0034] In this embodiment, after obtaining the configuration file of the substation, determine the signal status of the event signal of the device based on the configuration file. Optionally, based on obtaining the configuration file of the substation, in each port of the switch, determine the port connected to the publishing device in the device. According to the determined port connected to the publishing device, determine whether the signal status of the event signal of the device is a normal signal status or an abnormal signal status. Among them, each port of the above switch may be an optical port.

[0035] Step S103: In response to the signal status being a normal signal status, respectively verify the target relationship library and the current relationship library of the device based on the switch in the substation to obtain a verification result.

[0036] In the technical solution provided in step S103 of the present invention, the above device may include at least one publishing device and at least one subscribing device. Among them, the above subscribing device may be a device that receives an event signal from the publishing device. For example, the publishing device may be at least one of the following devices: protection device, measurement and control device, and intelligent terminal, etc. The subscribing device may be at least one of the following devices: a device that receives an event signal from the protection device, a device that receives an event signal from the measurement and control device, and a device that receives an event signal from the intelligent terminal. This is only an example here and is not specifically limited.

[0037] In this embodiment, the above target relationship library may be used to record the target communication relationship between the publishing device and the subscribing device in the case where the connection between the publishing device and the subscribing device through the switch is abnormal. The above current relationship library may be used to record the current communication relationship between the publishing device and the subscribing device in the case where the connection between the publishing device and the subscribing device through the switch is abnormal. For example, the above target relationship library may be an original standard database, and the above current relationship library may be a manufacturer setting database. This is only an example here and is not specifically limited.

[0038] In this embodiment, the above verification result can be used to represent the relationship between the target relationship database and the current relationship database. For example, the above verification result can be that the target relationship database is different from the current relationship database, or the target relationship database is the same as the current relationship database. This is only an example here and is not specifically limited.

[0039] In this embodiment, after determining the signal state of the event signal of the device based on the configuration file, in response to the signal state being a normal signal state, the target relationship database and the current relationship database of the device are respectively verified based on the switch in the substation to obtain a verification result. Optionally, based on determining the signal state of the event signal of the device, this embodiment performs a type analysis on the signal state of the event signal. If it is analyzed that the signal state of the event signal is a normal signal state, then according to the states of the respective ports of the switch in the substation, the target relationship database and the current relationship database of the device are respectively verified, and a verification result can be obtained, thereby achieving the purpose of verifying whether the target relationship database is the same as the current relationship database.

[0040] Step S104, in response to the verification result that the target relationship database is different from the current relationship database, upload the abnormal information in the current relationship database to the cloud.

[0041] In the technical solution provided in step S104 of the present invention above, the above abnormal information can be used to record the communication relationship different from the target communication relationship in the current communication relationship. Among them, the above abnormal information can be presented in at least one of the following forms: documents and tables, etc. This is only an example here and is not specifically limited.

[0042] In this embodiment, after, in response to the signal state being a normal signal state, the target relationship database and the current relationship database of the device are respectively verified based on the switch in the substation to obtain a verification result, in response to the verification result that the target relationship database is different from the current relationship database, upload the abnormal information in the current relationship database to the cloud. Optionally, based on obtaining the verification result, this embodiment judges the obtained verification result. If it is judged that the obtained verification result is that the target relationship database is different from the current relationship database, then upload the abnormal information in the current relationship database to the cloud.

[0043] In the above steps S101 to S104 of this application, when verifying the signals of a substation, the configuration file of the substation can be obtained. According to the obtained configuration file, the signal status of the event signals of the devices can be determined. If the signal status of the event signals is the normal signal status, then based on the switches in the substation, the target relational database and the current relational database of the devices can be verified respectively, and a verification result can be obtained. If the obtained verification result is that the above target relational database is different from the above current relational database, the abnormal information in the current relational database is uploaded to the cloud, thereby achieving the purpose of avoiding the negative impacts of cumbersome and error-prone work, extremely large workload, and high labor costs caused by manual operations, thus solving the technical problem of low efficiency in signal verification of the substation, and further achieving the technical effect of improving the efficiency of signal verification of the substation.

[0044] The above method of this embodiment will be further introduced below.

[0045] As an optional embodiment, step S102, determining the signal status of the event signals of the devices based on the configuration file, includes: determining at least one target port in the switch from the configuration file; determining the signal status based on the target port.

[0046] In this embodiment, the above target port can be the port connected to the publishing device.

[0047] In this embodiment, after obtaining the configuration file of the substation, at least one target port in the switch is determined from the configuration file. Optionally, based on obtaining the configuration file of the substation, at least one target port can be determined among the various ports of the switch.

[0048] In this embodiment, after determining at least one target port in the switch from the configuration file, the signal status is determined based on the target port. Optionally, based on determining at least one target port in the switch, according to the current status of the target port, the signal status of the event signals of the devices can be determined as the normal signal status or the abnormal signal status.

[0049] As an optional embodiment, determining the signal status based on the target port includes: determining that the signal status is the normal signal status in response to the current status of the target port being in the enabled state.

[0050] In this embodiment, after determining at least one target port in the switch from the configuration file, in response to the current state of the target port being in the enabled state, it is determined that the signal state is the normal signal state. Optionally, based on determining at least one target port in the switch, this embodiment determines whether the current state of the target port is in the enabled state. If it is determined that the current state of the target port is in the enabled state, it can be determined that the signal state of the event signal of the device is the normal signal state. For example, it can be determined that no GOOSE disconnection alarm signal is generated. This is only an example here and is not specifically limited.

[0051] As an optional embodiment, in step S103, in response to the signal state being the normal signal state, based on the switch in the substation, the target relationship library and the current relationship library of the device are respectively verified to obtain a verification result, including: in response to the signal state being the normal signal state, adjusting the current state of at least one target port in the switch; based on the adjusted current state and the alarm signal of the subscribed device, the target relationship library and the current relationship library are respectively verified to obtain a verification result.

[0052] In this embodiment, the above target port can be the port connected to the publishing device. The above alarm signal can be used to indicate that there is an abnormal connection between the publishing device and the subscribed device through the switch.

[0053] In this embodiment, after determining the signal state of the event signal of the device based on the configuration file, in response to the signal state being the normal signal state, the current state of at least one target port in the switch is adjusted. Optionally, based on determining the signal state of the event signal of the device, this embodiment performs a type analysis on the signal state of the event signal. If it is analyzed that the signal state of the event signal is the normal signal state, the current state of at least one target port in the switch is adjusted.

[0054] In this embodiment, after adjusting the current state of at least one target port in the switch in response to the signal state being the normal signal state, based on the adjusted current state and the alarm signal of the subscribed device, the target relationship library and the current relationship library are respectively verified to obtain a verification result. Optionally, based on adjusting the current state of at least one target port in the switch, this embodiment performs a type analysis on the adjusted current state. According to the obtained analysis result and the alarm signal of the subscribed device, the target relationship library and the current relationship library are respectively verified, and a verification result can be obtained, thereby achieving the purpose of verifying whether the target relationship library and the current relationship library are the same.

[0055] As an alternative embodiment, based on the adjusted current state and the alarm signals of the subscribed devices, the target relationship database and the current relationship database are respectively verified to obtain verification results, including: in response to the adjusted current state being the disabled state, determining the current communication relationship corresponding to the alarm signal; verifying each communication relationship in the current communication relationship corresponding to the alarm signal and the target communication relationship to obtain the verification results.

[0056] In this embodiment, after adjusting the current state of at least one target port in the switch in response to the signal state being the normal signal state, in response to the adjusted current state being the disabled state, the current communication relationship corresponding to the alarm signal is determined. Optionally, based on adjusting the current state of at least one target port in the switch, this embodiment performs a type analysis on the adjusted current state. If the obtained analysis result indicates that the adjusted current state is the disabled state, the current communication relationship corresponding to the alarm signal can be determined. For example, the name description of the GOOSE disconnection alarm signal can be determined. This is only an example here and is not specifically limited.

[0057] In this embodiment, after determining the current communication relationship corresponding to the alarm signal in response to the adjusted current state being the disabled state, each communication relationship in the current communication relationship corresponding to the alarm signal and the target communication relationship is verified to obtain the verification results. Optionally, based on determining the current communication relationship corresponding to the alarm signal, this embodiment verifies each communication relationship in the current communication relationship corresponding to the alarm signal and the target communication relationship, and the verification results can be obtained, thereby achieving the purpose of determining the relationship between the target relationship database and the current relationship database.

[0058] As an alternative embodiment, in step S104, in response to the verification result indicating that the target relationship database is different from the current relationship database, the abnormal information in the current relationship database is uploaded to the cloud, including: in response to the verification result indicating that there is a communication relationship in the current communication relationship that is different from the target communication relationship, the abnormal information is uploaded to the cloud.

[0059] In this embodiment, after verifying the target relationship database and the current relationship database of the device respectively based on the switch in the substation in response to the signal state being the normal signal state to obtain the verification results, in response to the verification result indicating that there is a communication relationship in the current communication relationship that is different from the target communication relationship, the abnormal information in the current relationship database is uploaded to the cloud. Optionally, based on obtaining the verification results, this embodiment judges the obtained verification results. If it is judged that the obtained verification result is that there is a communication relationship in the current communication relationship that is different from the target communication relationship, the abnormal information in the current relationship database is uploaded to the cloud.

[0060] In an embodiment of the present invention, when verifying the signals of a substation, a configuration file of the substation can be obtained. According to the obtained configuration file, the signal status of the event signals of the devices can be determined. If the signal status of the event signals is a normal signal status, then based on the switch in the substation, the target relational database and the current relational database of the devices are respectively verified to obtain a verification result. If the obtained verification result is that the above-mentioned target relational database is different from the above-mentioned current relational database, the abnormal information in the current relational database is uploaded to the cloud, thereby achieving the purpose of avoiding the negative impacts of cumbersome and error-prone work, extremely large workload, and high labor costs caused by manual operations, thus solving the technical problem of low efficiency of signal verification in the substation, and further achieving the technical effect of improving the efficiency of signal verification in the substation.

[0061] The technical solutions of the embodiments of the present invention will be illustrated below in conjunction with preferred embodiments.

[0062] Currently, in a substation, the correctness of the GOOSE disconnection signal is directly related to the reliability of remote monitoring in the substation. In the related art, the correctness of the GOOSE disconnection signal is often verified by manual operation. For example, after the acceptance personnel confirm that the GOOSE network in the substation is correct, the staff on one side sequentially pull out the GOOSE process layer optical fibers of the intelligent devices. After pulling out, wait for a period of time, and then inform the staff on the other side of the intelligent device whose optical fiber is pulled out. The staff on the other side confirm whether the GOOSE disconnection signal sent by the intelligent device on the other side that subscribes to the GOOSE information of the intelligent device whose optical fiber is pulled out is consistent with the intelligent device whose optical fiber is pulled out in the monitoring background.

[0063] However, such manual operations have the negative impacts of cumbersome and error-prone work, extremely large workload, and high labor costs, resulting in the technical problem of low efficiency of signal verification in the substation.

[0064] To solve the above technical problems, an embodiment of the present invention proposes a method for verifying the signals of a substation. According to the obtained configuration file, it can be determined whether the signal status of the event signals of the devices is a normal signal status. If the signal status of the event signals of the devices is a normal signal status, then the switch in the substation is used to verify the target relational database and the current relational database of the devices to obtain a verification result, and in the case where the verification result is that the target relational database is different from the current relational database, the abnormal information in the current relational database is uploaded to the cloud, thereby achieving the purpose of avoiding the negative impacts of cumbersome and error-prone work, extremely large workload, and high labor costs caused by manual operations, thus solving the technical problem of low efficiency of signal verification in the substation, and further achieving the technical effect of improving the efficiency of signal verification in the substation.

The above-mentioned automatic remote operation and maintenance master station 207 can be used to control the station-side automatic substation and receive SOE signals. Among them, the station-side automatic substation can be the automatic remote operation and maintenance terminal 208 deployed on the substation station control layer network. The above-mentioned automatic remote operation and maintenance terminal 208 can be used to access the station control layer network and receive and control the information of the monitoring background device 2094. For example, the above-mentioned automatic remote operation and maintenance terminal 208 can be used to obtain GOOSE disconnection alarm signal information.

[0068] In this embodiment, the above-mentioned secondary intelligent operation and maintenance master station 200 can be connected to the secondary intelligent operation and maintenance Web client 201 through the forward / reverse isolation device 203 and the firewall 204. The above-mentioned protection information master station 202 can be directly connected to the secondary intelligent operation and maintenance master station 200. The above-mentioned automatic remote operation and maintenance master station 207 can also be directly connected to the secondary intelligent operation and maintenance master station 200.

[0069] In this embodiment, the above intelligent recorder 205 can be connected to the protection information master station 202 through the dispatching data network. The above intelligent recorder 205 can be connected to the process layer switch 206 through the C3 network. Among them, the C3 network can be a dedicated Ethernet network of the process layer switch, which can be used for the intelligent recorder to monitor and control the process layer switch.

[0070] In this embodiment, the above automation remote operation and maintenance terminal 208 can be connected to the automation remote operation and maintenance master station 207 through the dispatching data network. The above automation remote operation and maintenance terminal 208 can upload the GOOSE disconnection alarm signal information to the automation remote operation and maintenance master station 207.

[0071] In this embodiment, the above protection device 2091, measurement and control device 2092, and intelligent terminal 2093 can upload the GOOSE disconnection alarm signal information to the monitoring background device 2094. The above protection device 2091, measurement and control device 2092, and intelligent terminal 2093 can be connected to the optical ports of the process layer switch 206.

[0072] In this embodiment, through the remote automatic test and acceptance method for GOOSE disconnection alarm signals in an intelligent substation, according to the obtained configuration file, it can be determined whether the signal status of the event signal of the device is a normal signal status. If the signal status of the event signal of the device is a normal signal status, then the switch in the substation is used to verify the target relationship library and the current relationship library of the device, and a verification result can be obtained. And in the case where the verification result is that the target relationship library is different from the current relationship library, the abnormal information in the current relationship library is uploaded to the cloud. For example, FIG. 2(b) is a schematic diagram of a remote automatic test and acceptance method for GOOSE disconnection alarm signals in an intelligent substation according to an embodiment of the present invention. As shown in FIG. 2(b), the method may include the following steps:

[0073] Step S211, read the SCD file, and analyze and record the access situation of the switch.

[0074] In the technical solution provided in step S211 of the present invention, the SCD file of the intelligent substation is retrieved, and the access situation of the secondary equipment is analyzed. The secondary intelligent operation and maintenance master station selects the substation to be tested and accepted, obtains the SCD file of the intelligent substation through the protection information master station, and then through analysis criteria, confirms the access relationship between the optical ports of the secondary equipment, the process layer switch, and its ports, and forms an optical port record in a standard format: switch number - optical port number - name of the secondary equipment.

[0075] In this embodiment, the above analysis criteria refer to confirming in sequence the secondary devices connected to the INPort ports No. 1-16 of the process layer switches of the entire station, among which the ports with serial numbers greater than 16 are cascade ports between switches, which have no actual connected secondary devices and are not within the scope of analysis; the forwarding example analysis table in Table 1 below specifically explains that the secondary device connected to the INPort port No. 1 of the process layer switch SW221103 is the 220kV Qishajia Line 4150 Main-One Intelligent Terminal, and a corresponding standard format optical port record is formed, i.e., SW221103-1-220kV Qishajia Line 4150 Main-One Intelligent Terminal.

[0077]

[0078] After reading the SCD file, analyzing and recording the access status of the switch, the process proceeds to step S212 to analyze the GOOSE subscription information of the secondary device.

[0079] In the technical solution provided in step S212 of the present invention, the GOOSE subscription information of the secondary device is analyzed. The secondary intelligent operation and maintenance master station extracts the GOOSE subscription information of the secondary device in the SCD file, confirms the name of the opposite-side publishing device to which the GOOSE information of the secondary devices of the entire station is subscribed, and records it to form a subscription association table. Among them, the subscription association table can refer to the relationship table of the secondary devices that each secondary device of the entire station corresponds to and subscribes to its GOOSE information, so as to facilitate the subsequent GOOSE disconnection alarm analysis.

[0080] After analyzing the GOOSE subscription information of the secondary device, the process proceeds to step S213 to confirm whether the GOOSE link of the entire site is normal.

[0081] In the technical solution provided in the above step S213 of the present invention, the secondary intelligent operation and maintenance master station retrieves the alarm signal of the substation received by the automated remote operation and maintenance master station, and confirms that there is no GOOSE disconnection alarm signal of the substation.

[0082] If it is confirmed that there is an abnormal link in the GOOSE link of the whole station, then go to step S214 and step S215 to check the abnormal link signal and record it, and summarize the special results of the equipment, archive the records and publish them. If it is confirmed that the GOOSE link of the whole station is normal, then go to step S216 to confirm whether the ports of the process layer switch have been verified.

[0083] If it is confirmed that all ports of the process layer switch have been verified, then proceed to step S215. If it is confirmed that all ports of the process layer switch have not been verified, then proceed to steps S217 and S218 to disable the ports of the unverified process layer switch and confirm whether the GOOSE disconnection alarm signal is correct.

[0084] In the technical solution provided in step S217 of the present invention, the optical ports of the process layer switches are disabled and restored alternately to confirm that the GOOSE disconnection alarm signal is correct. The secondary intelligent operation and maintenance master station issues a command to disable the optical ports of the process layer switches. Through the protection information master station, the process layer switches at the substation end are configured to disable the optical ports of the entire substation in sequence. After disabling the optical ports, the alarm signals of the substation received by the automated remote operation and maintenance master station are retrieved. It is judged whether the name description of the GOOSE disconnection alarm signal sent by the subscribed device after the optical port to which the secondary device is connected is disabled is consistent with the subscription association table, and the judgment result is recorded. After the judgment is completed, the function of the optical port is restored. After the restoration, it is checked that there is no GOOSE disconnection alarm signal in the substation.

[0085] In this embodiment, the name description of the above GOOSE disconnection alarm signal may refer to the alarm signal sent by the subscribed device, and the specific format of the description may be: "subscribed device name" + "receives" + "publishing device name" + "process layer network to which the subscribed device is connected" + "alarm". For example, if the main protection of the 220 kV Zhuosha A line is the subscribed device and the main intelligent terminal of the 220 kV Zhuosha A line is the publishing device, then the description of the GOOSE disconnection alarm signal for the main protection of the 220 kV Zhuosha A line to receive its GOOSE information is: The main protection of the 220 kV Zhuosha A line receives the alarm of network A1 of the main intelligent terminal of the 220 kV Zhuosha A line. This is only for illustrative purposes and is not specifically limited.

[0086] If it is confirmed that the GOOSE disconnection alarm signal is incorrect, step S219 is entered to record the abnormal alarm signal and the port. If it is confirmed that the GOOSE disconnection alarm signal is correct, step S220 is entered to restore the ports of the disabled process layer switches.

[0087] In the technical solution provided in step S219 of the present invention, the acceptance results of the GOOSE disconnection alarm signals are summarized and published. The judgment results of the above-tested GOOSE disconnection alarm signals are recorded in the corresponding substation-end acceptance database and published to the secondary intelligent operation and maintenance Web client for users to check and confirm and handle abnormal alarms in a timely manner.

[0088] In this embodiment, according to the obtained configuration file, it can be determined whether the signal state of the event signal of the device is a normal signal state. If the signal state of the event signal of the device is a normal signal state, the switch in the substation is used to verify the target relationship library and the current relationship library of the device, and a verification result can be obtained. And in the case where the verification result is that the target relationship library is different from the current relationship library, the abnormal information in the current relationship library is uploaded to the cloud, thereby achieving the purpose of avoiding the negative impacts of cumbersome and error-prone work, extremely large workload, and high labor costs caused by manual operations, thus solving the technical problem of low efficiency of signal verification in the substation, and further realizing the technical effect of improving the efficiency of signal verification in the substation.
