[0028] Figure 1 is a flow chart 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, obtaining a configuration file of a substation.

[0030] In the technical solution provided in the above step S101 of the present invention, the above configuration file can be used at least to record the association relationship between the various devices in the substation and the communication signals between the various devices in the substation. For example, the above configuration file can be a substation configuration description (SCD) file, which is only used as an example and is not specifically limited.

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

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

[0033] In the technical solution provided in the above 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 state 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 state may be a normal signal state or an abnormal signal state, which is only used as an example and is not specifically limited.

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

[0035] Step S103, in response to the signal state being a 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.

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

[0037] In this embodiment, the target relationship library can be used to record the target communication relationship between the publishing device and the subscribing device when the publishing device and the subscribing device are abnormally connected through the switch. The current relationship library can be used to record the current communication relationship between the publishing device and the subscribing device when the publishing device and the subscribing device are abnormally connected through the switch. For example, the target relationship library can be an original standard database, and the current relationship library can be a manufacturer setting database, which is only used as an example here and is not specifically limited.

[0038] In this embodiment, the verification result can be used to indicate the relationship between the target relationship library and the current relationship library. For example, the verification result can be that the target relationship library is different from the current relationship library, or that the target relationship library is the same as the current relationship library, which is only used as an example 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, 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. Optionally, this embodiment performs a type analysis on the signal state of the event signal on the basis of determining the signal state of the event signal of the device. If the signal state of the event signal is analyzed to be a normal signal state, the target relationship library and the current relationship library of the device are respectively verified according to the states of each port of the switch in the substation, 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.

[0040] Step S104, in response to the verification result 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.

[0041] In the technical solution provided in step S104 of the present invention, the above-mentioned abnormal information can be used to record the communication relationship in the current communication relationship that is different from the target communication relationship. The above-mentioned abnormal information can be presented in at least one of the following forms: document and table, etc., which are only used as examples and are not specifically limited.

[0042] In this embodiment, in response to the signal state being a 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, and after obtaining the verification result, in response to the verification result 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. Optionally, this embodiment judges the obtained verification result on the basis of the obtained verification result, and if it is judged that the obtained 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.

[0043] In the above steps S101 to S104 of the present application, when verifying the signal of the substation, the configuration file of the substation can be obtained. According to the obtained configuration file, the signal state of the event signal of the device can be determined. If the signal state of the event signal is a normal signal state, the target relationship library and the current relationship library of the device are verified respectively according to the switch in the substation, and the verification result can be obtained. If the obtained verification result is that the above target relationship library is different from the above current relationship library, the abnormal information in the current relationship library is uploaded to the cloud, thereby achieving the purpose of avoiding the negative effects of cumbersome and error-prone work, huge workload and high labor costs caused by manual operation, thereby solving the technical problem of low efficiency of signal verification of substations, and then achieving the technical effect of improving the efficiency of signal verification of substations.

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

[0045] As an optional implementation manner, step S102, determining the signal state of the event signal of the device based on the configuration file, includes: determining at least one target port in the switch from the configuration file; and determining the signal state based on the target port.

[0046] In this embodiment, the target port may be a port connected to a 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, this embodiment can determine at least one target port in each port of the switch based on obtaining the configuration file of the substation.

[0048] In this embodiment, after determining at least one target port in the switch from the configuration file, the signal state is determined based on the target port. Optionally, this embodiment can determine whether the signal state of the event signal of the device is a normal signal state or an abnormal signal state based on the current state of the target port after determining at least one target port in the switch.

[0049] As an optional embodiment, determining the signal state based on the target port includes: in response to a current state of the target port being in an enabled state, determining that the signal state is a normal signal 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, the signal state is determined to be a normal signal state. Optionally, this embodiment determines whether the current state of the target port is an enabled state based on determining at least one target port in the switch. If it is determined that the current state of the target port is an enabled state, it can be determined that the signal state of the event signal of the device is a normal signal state. For example, it can be determined that a GOOSE disconnection alarm signal is not generated. This is only an example and is not specifically limited.

[0051] As an optional implementation method, step S103, in response to the signal state being a 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 a 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 target port may be a port connected to the publishing device. The alarm signal may be used to indicate that the publishing device and the subscribing device are abnormally connected through the switch.

Optionally, this embodiment performs a type analysis on the signal state of the event signal based on the determination of the signal state of the event signal of the device, and if the analysis shows that the signal state of the event signal is a 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 a normal signal state, the target relationship library and the current relationship library are verified based on the adjusted current state and the alarm signal of the subscription device to obtain a verification result. Optionally, this embodiment performs a type analysis on the adjusted current state based on the adjustment of the current state of at least one target port in the switch, and verifies the target relationship library and the current relationship library based on the obtained analysis result and the alarm signal of the subscription device to obtain a verification result, thereby achieving the purpose of verifying whether the target relationship library and the current relationship library are the same.

[0055] As an optional implementation method, based on the adjusted current state and the alarm signal of the subscribed device, the target relationship library and the current relationship library are verified respectively to obtain a verification result, including: in response to the adjusted current state being a disabled state, determining the current communication relationship corresponding to the alarm signal; verifying the current communication relationship corresponding to the alarm signal and each communication relationship in the target communication relationship to obtain a verification result.

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

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

[0058] As an optional implementation method, step S104, in response to the verification result that the target relationship library is different from the current relationship library, uploading the abnormal information in the current relationship library to the cloud, includes: in response to the verification result that there is a communication relationship in the current communication relationship that is different from the target communication relationship, uploading the abnormal information to the cloud.

[0059] In this embodiment, in response to the signal state being a 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, and after obtaining the verification result, in response to the verification result that there is a communication relationship different from the target communication relationship in the current communication relationship, the abnormal information is uploaded to the cloud. Optionally, this embodiment judges the obtained verification result on the basis of obtaining the verification result, and if it is judged that the obtained verification result is that there is a communication relationship different from the target communication relationship in the current communication relationship, the abnormal information in the current relationship library is uploaded to the cloud.

[0060] In an embodiment of the present invention, when verifying the signal of the substation, the configuration file of the substation can be obtained. According to the obtained configuration file, the signal state of the event signal of the device can be determined. If the signal state of the event signal is a normal signal state, the target relationship library and the current relationship library of the device are verified respectively according to the switch in the substation, and a verification result can be obtained. If the obtained verification result is that the above-mentioned target relationship library is different from the above-mentioned current relationship library, the abnormal information in the current relationship library is uploaded to the cloud, thereby achieving the purpose of avoiding the negative effects of cumbersome and error-prone work, huge workload and high labor costs caused by manual operation, thereby solving the technical problem of low efficiency of signal verification of the substation, and then achieving the technical effect of improving the efficiency of signal verification of the substation.

[0061] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0062] At present, in substations, the correctness of the GOOSE disconnection signal is directly related to the reliability of remote monitoring of substations. In related technologies, manual operation is often relied on to verify the correctness of the GOOSE disconnection signal. For example, after the acceptance personnel confirm that the GOOSE networking of the substation is correct, the staff on one side pull out the GOOSE process layer optical fiber of the smart device in turn, wait for a period of time after pulling out, and then inform the staff on the opposite side of the smart device that pulled out the optical fiber. The staff on the opposite side confirms in the monitoring background whether the GOOSE disconnection signal sent by the smart device on the opposite side that subscribes to the GOOSE information of the smart device is consistent with the smart device that pulled out the optical fiber.

[0063] However, such manual operation has negative effects such as tedious work, easy to make mistakes, huge workload and high labor cost, thus leading to the technical problem of low efficiency of signal verification of substation.

[0064] In order to solve the above technical problems, an embodiment of the present invention proposes a signal verification method for a substation, and 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 target relationship library of the device and the current relationship library are verified by using the switch in the substation, and a verification result can be obtained. 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 effects of cumbersome and error-prone work, huge workload and high labor costs caused by manual operation, thereby solving the technical problem of low efficiency of signal verification of substations, and then achieving the technical effect of improving the efficiency of signal verification of substations.

The above-mentioned process layer switch 206 can be used to provide an interactive platform for secondary equipment such as protection devices, measurement and control devices and intelligent terminals to transmit and forward process layer information. The above-mentioned automated remote operation and maintenance master station 207 can be used to control the station-end automated substation and receive SOE signals. Among them, the station-end automated substation can be an automated remote operation and maintenance terminal 208 deployed in the substation control layer network. The above-mentioned automated remote operation and maintenance terminal 208 can be used to access the station control layer network, as well as to receive and control information from the monitoring background device 2094. For example, the above-mentioned automated remote operation and maintenance terminal 208 can be used to obtain GOOSE link break alarm signal information.

[0068] In this embodiment, the 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 security master station 202 can be directly connected to the secondary intelligent operation and maintenance master station 200. The above-mentioned automated 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 intelligent recorder 205 can be connected to the security master station 202 through the dispatching data network. The intelligent recorder 205 can be connected to the process layer switch 206 through the C3 network. 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 automation remote operation and maintenance terminal 208 can be connected to the automation remote operation and maintenance main station 207 through the dispatching data network. The automation remote operation and maintenance terminal 208 can upload the GOOSE disconnection alarm signal information to the automation remote operation and maintenance main station 207.

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

[0072] In this embodiment, through the remote automatic test and acceptance method of the GOOSE disconnection alarm signal of the smart substation, it is possible to determine whether the signal state of the event signal of the device is a normal signal state according to the acquired configuration file. If the signal state of the event signal of the device is a normal signal state, the target relationship library of the device and the current relationship library are verified by using the switch in the substation to obtain the verification result. When 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, FIG2(b) is a schematic diagram of a remote automatic test and acceptance method of the GOOSE disconnection alarm signal of a smart substation according to an embodiment of the present invention. As shown in FIG2(b), the method may include the following steps:

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

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

[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.

[0076] Table 1 Forwarding example analysis table

[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 the above step S217 of the present invention, the optical ports of the process layer switches are disabled and restored in turn 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 port of the process layer switch, and the process layer switch configuration at the substation end is controlled by the security master station to disable the optical ports of the entire station process layer switches in turn. After disabling the optical port, the alarm signal of the substation received by the automated remote operation and maintenance master station is retrieved to determine whether the name description of the GOOSE disconnection alarm signal issued by its subscribing device is consistent with the subscription association table after the optical port connected to the secondary device is disabled, and the judgment result is recorded. After the judgment is completed, the function of the optical port is restored, and after 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-mentioned GOOSE chain break alarm signal may refer to the alarm signal issued by the subscribing device, and the specific format of the description may be: "subscribing device name" + "receiving" + "publishing device name" + "process layer network connected to the subscribing device" + "alarm". For example, the 220kV Zhuosha A line main protection is the subscribing device, and the 220kV Zhuosha A line main intelligent terminal is the publishing device. Then, the GOOSE chain break alarm signal of the 220kV Zhuosha A line main protection receiving its GOOSE information is described as: the 220kV Zhuosha A line main protection receives the 220kV Zhuosha A line main intelligent terminal A1 network alarm. This is only an example and is not specifically limited.

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

[0087] In the technical solution provided in the above step S219 of the present invention, the acceptance results of the GOOSE disconnection alarm signal are summarized and published. The judgment result of the GOOSE disconnection alarm signal of the above test is recorded in the corresponding station acceptance database and published to the secondary intelligent operation and maintenance Web user terminal for users to check and confirm and handle abnormal alarms in time.

[0088] In this embodiment, according to the configuration file obtained, 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 target relationship library of the device and the current relationship library are verified by using the switch in the substation, and the verification result can be obtained. 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 effects of cumbersome and error-prone work, huge workload and high labor costs caused by manual operation, thereby solving the technical problem of low efficiency of signal verification of substations, and then achieving the technical effect of improving the efficiency of signal verification of substations.
