Background Art

[0002] The information transmission of smart substations relies on optical fiber, so the correctness of the optical fiber link configuration is crucial to the reliable operation of smart substations. At present, the acceptance of the correctness of the optical fiber link is basically realized by manual operation. Generally, after confirming that the substation optical fiber link networking is correct and there is no abnormal alarm, the staff on the process layer switch side pulls out the optical fiber connected to the specific intelligent device on the switch side according to the drawings, and connects the optical digital tester to confirm that the intelligent device that publishes information on the opposite side of the optical fiber is consistent with the planning of the drawings. At the same time, after the pull-out, the staff on the opposite side confirms that the optical fiber is pulled out by checking the GOOSE link break alarm on the device interface. Subsequently, because the optical fiber of the smart substation adopts redundant configuration (the configuration and transmission data of the two independent optical fibers are completely consistent), it is necessary to reconnect the optical fiber on the process layer switch side. The staff on the intelligent device side pulls out the first and second optical fibers in turn, and the staff on the switch side confirms that the optical port working light of the corresponding switch is off (confirming that the two optical fibers are not staggered), and finally confirm that the optical fiber link configuration is correct.

[0024] As introduced in the background technology, the existing technology has the problem that the work is cumbersome and error-prone when accepting optical fiber links.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] In this embodiment, a method for automatic verification of an optical fiber link of a smart substation running on a mobile terminal, a computer terminal or a similar computing device 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 a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0027] Figure 1 1 is a flow chart of an automatic verification method for an optical fiber link of a smart substation according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0028] Step S101, determining whether the states of the GOOSE link-break alarm signals of the smart substation are all in a reset state, wherein the GOOSE link-break alarm signal refers to an optical fiber link state alarm signal issued by the smart device, and the reset state indicates that the optical fiber link of the smart device is normal without a link-break alarm;

[0029] Specifically, the GOOSE link break alarm signal refers to the optical fiber link status alarm signal issued by the intelligent device, and the specific format of the description is: "Subscriber device name" + "Receive" + "Publisher device name" + "Process layer network to which the subscriber device is connected" + "Alarm".

[0030] Step S102, when the states of the GOOSE disconnection alarm signals are all in the above-mentioned reset state, obtaining a switch optical port configuration table, wherein the switch optical port configuration table is a mapping relationship table between the number of the above-mentioned intelligent device accessing the switch and the optical port sequence number;

[0031] Among them, the optical port configuration table refers to a table attached to the design drawing, which clearly specifies the intelligent device and its optical port to which the optical port of each process layer switch corresponds.

[0032] Step S103, according to the optical port configuration table of the switch, the optical port control commands of the switch are issued in sequence to control the switch to exit the optical port enable in sequence, and the GOOSE link break alarm signal is retrieved in real time to verify the optical fiber link of the smart substation.

[0033] Specifically, send the process layer switch optical port control command to confirm whether the GOOSE link break alarm signal is normal. The secondary intelligent operation and maintenance master station issues the process layer switch disable optical port command in turn according to the optical port configuration table. After the security master station controls the process layer switch configuration at the substation end, the process layer switch optical port is sequentially exited from being enabled. After disabling the optical port, call the automated remote operation and maintenance master station to receive the real-time alarm signal of the substation being verified to determine whether the GOOSE link break alarm signal is normal, that is, after the optical port of the process layer switch connected to the intelligent device is disabled, the intelligent device and the intelligent device on the opposite side that subscribes to the published information simultaneously meet the fiber optic link disconnection condition, where the fiber optic link disconnection condition refers to the intelligent device issuing a link break alarm, the corresponding optical power received by the optical fiber port exceeds the lower limit, and the intelligent device on the opposite side that subscribes to the published information issues a link break alarm.

[0034] The lower limit of the optical power means that the received optical power of the corresponding optical port is lower than -31dBm.

[0035] The specific format of the broken link alarm is: "Subscriber device name" + "Receive" + "Publisher device name" + "Process layer network to which the subscriber device is connected" + "Alarm".

[0036] Through this embodiment, it is determined whether the status of each GOOSE link-break alarm signal of the smart substation is in the reset state, wherein the GOOSE link-break alarm signal refers to the optical fiber link status alarm signal issued by the smart device, and the reset state indicates that the optical fiber link of the smart device is normal and there is no link-break alarm; when the status of the GOOSE link-break alarm signal is in the reset state, the switch optical port configuration table is obtained, wherein the switch optical port configuration table is a mapping relationship table between the number of the smart device access switch and the optical port sequence number; according to the switch optical port configuration table, the optical port control commands of the switch are issued in sequence to control the switch to exit the optical port enable in sequence, and the GOOSE link-break alarm signal is retrieved in real time to verify the optical fiber link of the smart substation. By controlling the optical port enablement of the switch and monitoring the GOOSE link-break alarm signal, the optical fiber link of the smart substation is verified, which solves the problems of cumbersome and error-prone work, huge workload, high labor cost, and artificial damage to the optical fiber caused by frequent plugging and unplugging of optical fibers in the existing optical fiber link acceptance.

[0037] During the specific implementation process, after controlling the above-mentioned switches to exit the optical port enable in sequence and retrieving the above-mentioned GOOSE link break alarm signal in real time to verify the above-mentioned optical fiber link of the above-mentioned smart substation, the above-mentioned method also includes: when it is determined that the above-mentioned GOOSE link break alarm signal is abnormal, recording the optical fiber link abnormality corresponding to the above-mentioned alarm signal.

[0038] After verifying the optical fiber link of the smart substation, if the GOOSE link break alarm signal is abnormal, the method records and processes the optical fiber link corresponding to the abnormal GOOSE link break alarm signal until all the optical fiber links of the smart substation are verified, and generates the verification results of the optical fiber links of the smart substation, wherein the verification results record the optical fiber links that have successfully verified and the optical fiber links that have failed to verify.

[0039] Specifically, after controlling the above-mentioned switches to exit the optical port enabling in sequence and calling the above-mentioned GOOSE link break alarm signal in real time to verify the above-mentioned optical fiber link of the above-mentioned smart substation, the above-mentioned method also includes: when it is determined that the above-mentioned GOOSE link break alarm signals are normal, completing the automatic verification of the above-mentioned optical fiber link of the above-mentioned smart substation, controlling the above-mentioned switches to restore the optical port enabling; generating an automatic verification report, and sending the above-mentioned automatic verification report to the intelligent operation and maintenance web user terminal.

[0040] After verifying the optical fiber link of the smart substation, the method controls the switch to restore all optical port enablement when the GOOSE link break alarm signals are normal, generates a verification report, and sends it to the user through the smart operation and maintenance web client.

[0041] More specifically, when the status of the above-mentioned GOOSE link break alarm signal is the above-mentioned restoration state, after obtaining the switch optical port configuration table, the above-mentioned method also includes: checking whether the communication status between the Baoxin master station and the above-mentioned smart substation is normal; when checking that the communication status between the above-mentioned Baoxin master station and the above-mentioned smart substation is abnormal, generating a prompt message, wherein the above-mentioned prompt message is used to prompt that the communication status between the above-mentioned Baoxin master station and the above-mentioned smart substation is abnormal.

[0042] When checking that the communication status between the Baoxin master station and the smart substation is abnormal, the method generates a prompt message and sends the prompt message to the user through the smart operation and maintenance web user terminal to inform the user that the communication status between the Baoxin master station and the smart substation is abnormal.

[0043] Further, after determining whether the states of the GOOSE link break alarm signals of the smart substation are all in the reset state, the method further comprises: when it is determined that the state of the GOOSE link break alarm signal of the smart substation is not in the reset state, recording the abnormality of the optical fiber link corresponding to the GOOSE link break alarm signal;

[0044] When determining that the state of at least one GOOSE link break alarm signal of the smart substation is not a restored state, the method records the optical fiber link corresponding to the GOOSE link break alarm signal, generates a prompt report, and sends it to the user through the smart operation and maintenance web user terminal, so as to prompt the user that the state of the GOOSE link break alarm signal is not the optical fiber link information corresponding to the restored state, so as to facilitate the user to check the optical fiber link.

[0045] Before determining whether the status of the GOOSE link break alarm signal of the smart substation is all in the reset state, the method further includes: selecting a smart substation that needs to perform optical fiber link verification, and performing the optical fiber link verification according to the voltage level and substation name of the smart substation.

[0046] The secondary intelligent operation and maintenance master station of this method selects the intelligent substation that needs to be verified for the optical fiber link, enters the verification substation name for verification, and then conducts the test. The verification substation name refers to the voltage level + substation name, for example: 220kV (voltage level) and test (substation name), that is, 220kV test station;

[0047] Furthermore, the alarm signal is retrieved in real time to confirm whether the above-mentioned GOOSE link break alarm signal is normal, including: retrieving the alarm signal in real time to determine the size relationship between the lower limit of the optical power received by the optical port of the above-mentioned alarm signal and the lower limit of the preset optical power; and determining whether the above-mentioned GOOSE link break alarm signal is normal according to the above-mentioned size relationship.

[0048] Among them, the preset optical power lower limit can be set to -31dBm. When controlling the enabling of the exit optical port of the switch, the lower limit value of the optical port receiving optical power that enables the exit optical port is called up. When it is determined that the lower limit of the optical port receiving optical power is lower than the set -31dBm, the GOOSE link break alarm signal is considered normal; otherwise, the GOOSE link break alarm signal is determined to be abnormal, and the corresponding optical fiber link abnormality is recorded, and a verification report is generated and sent to the user through the intelligent operation and maintenance web client.

[0049] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the automatic verification method of the optical fiber link of the smart substation of the present application will be described in detail below in combination with specific embodiments.

[0050] The existing acceptance of the correctness of optical fiber links has problems such as cumbersome and error-prone work, huge workload, high labor costs, and frequent plugging and unplugging of optical fibers causing human damage to the optical fibers. Therefore, a method and system for remote automatic verification of optical fiber links in smart substations is needed to achieve automated and efficient acceptance under the premise of reliable acceptance, avoid human misjudgment in manual acceptance, reduce labor costs, and reduce the number of fiber plugging and unplugging times.

[0051] The present embodiment relates to a specific automatic verification method and system for optical fiber links in smart substations. The secondary smart operation and maintenance master station links the smart recording master station, the automated remote operation and maintenance master station, the secondary equipment supporting the substation end, and the secondary smart operation and maintenance Web client. Based on the optical port configuration of the substation process layer switch, the smart substation process layer switch optical port is remotely enabled with the help of an intelligent recorder. The background link signal is monitored in real time at the automated remote operation and maintenance master station simultaneously. The linkage acceptance is carried out in a timely and high-quality manner, the acceptance process record information is summarized, and the acceptance results are published to the secondary smart operation and maintenance Web client.

[0053] The secondary intelligent operation and maintenance master station refers to the master station system that can monitor and control secondary equipment, issue intelligent recorder control commands, and perform background monitoring SOE signal analysis and processing.

[0055] The Baoxin master station refers to the master station system used by the protection professional to control the Baoxin substation equipment at the station end and receive information. It is also used to receive control commands from the secondary intelligent operation and maintenance master station;

[0056] The station-side information-guaranteeing substation refers to an intelligent wave recorder, which is used to receive station-side secondary equipment information and issue secondary equipment control commands;

[0057] The process layer switch refers to an optical switch that provides 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 secondary equipment is connected to the optical fiber transceiver port of the corresponding process layer switch according to the port configured by SCD, and the process layer switch is connected to the intelligent recorder via the C3 network; the process layer network in the substation adopts a redundant configuration, and is configured with A1 network process layer switch, A2 network process layer switch, B1 network process layer switch, and B2 network process layer switch. The redundant configuration means that the A1 network process layer switch and the A2 network process layer switch transmit and forward information consistently. The intelligent device connected to the A1A2 network process layer network is configured with two optical ports to access the corresponding switch. When a single optical port is abnormal, the switch device fails or loses power, it will not affect the device information transmission and reception, thereby ensuring reliability. The same applies to the B1B2 network process layer switch and intelligent device.

[0058] C3 network refers to the dedicated Ethernet network of process layer switches, which is used for intelligent recorders to monitor and control process layer switches;

[0059] The automation remote operation and maintenance master station refers to the master station system used by automation professionals to control station-side automation substations and receive SOE signals;

[0060] The station-side automation substation refers to an automated remote operation and maintenance terminal deployed in the substation control layer network. The terminal accesses the station control layer network to receive and control the monitoring background information. In the present invention, it is used to obtain the GOOSE disconnection alarm signal information.

[0061] The flowchart of the automatic verification method of the optical fiber link of the specific intelligent substation is as follows: Figure 3 As shown;

[0062] Step S1: Select the verification substation. The secondary intelligent operation and maintenance master station selects the intelligent substation that needs to be verified for the optical fiber link, enters the verification substation name for verification, and then conducts the test;

[0063] The name of the verification substation refers to the voltage level + substation name, for example 220kV (voltage level) and test (substation name), that is, 220kV test station.

[0064] Step S2: Confirm that the link status of the entire station is normal. The secondary intelligent operation and maintenance master station retrieves the information of the automated remote operation and maintenance master station in real time to check whether the GOOSE disconnection alarm signal status of the substation being verified is all restored;

[0065] Among them, the GOOSE link break alarm signal refers to the optical fiber link status alarm signal issued by the intelligent device, and the specific format is described as: "Subscriber device name" + "Receive" + "Publisher device name" + "Process layer network connected to the subscriber device" + "Alarm"; the recovery state means that the optical fiber links of the intelligent device are normal and there is no link break alarm.

[0066] Step S3: Import the optical port configuration table of the process layer switch. Import the optical port configuration table of the process layer switch of the substation into the secondary intelligent operation and maintenance master station. The secondary operation and maintenance master station analyzes the optical port configuration table, records the specific intelligent device access switch number and optical port sequence number, and forms a mapping relationship;

[0067] The above optical port configuration table refers to a table attached to the design drawing, which specifies the intelligent device and its optical port to which the optical port of each process layer switch corresponds.

[0068] Step S4: Confirm that the communication status between the substation and the Baoxin master station is normal. The secondary intelligent operation and maintenance master station checks the communication status of the Baoxin master station to the verification substation, and only performs remote control operations after confirming that the communication status is normal.

[0069] Step S5: Send the process layer switch optical port control command to confirm whether the GOOSE link break alarm signal is normal. The secondary intelligent operation and maintenance master station takes turns issuing commands to disable the optical port of the process layer switch according to the optical port configuration table. After the Baoxin master station controls the configuration of the process layer switch at the substation end, the optical ports of the process layer switches are sequentially exited. After disabling the optical port, the real-time alarm signal of the substation being verified is received by the automated remote operation and maintenance master station to determine whether the GOOSE link break alarm signal is normal, that is, after the optical port of the process layer switch to which the intelligent device is connected is disabled, the intelligent device and the intelligent device on the opposite side that subscribes to the published information simultaneously meet the fiber optic link disconnection condition; after confirmation, restore the enabling of the process layer switch optical port;

[0070] The above-mentioned fiber link disconnection condition refers to that the intelligent device issues a link disconnection alarm when the corresponding optical fiber port receiving optical power exceeds the lower limit and the intelligent device on the opposite side that subscribes to the published information issues a link disconnection alarm.

[0071] The specific format of the link break alarm is: "Subscriber device name" + "Receive" + "Publisher device name" + "Process layer network to which the subscriber device is connected" + "Alarm". Figure 4As shown, when the main protection of line B 2765 is used as the main publishing object, the main intelligent terminal of line B 2765, #1 / #2M busbar A set protection, and line B 2765 measurement and control are the opposite-side subscription objects. After disabling the optical port function of the main protection of line B 2765 in the A1 network process layer switch, the main protection of line B 2765 sends out the A1 network disconnection alarm received from the main intelligent terminal of line B 2765 and #1 / #2M busbar A set protection, and at the same time, the main intelligent terminal of line B 2765, #1 / #2M busbar A set protection, and line B 2765 measurement and control send out the A1 network disconnection alarm received from the main protection of line B 2765;

[0072] The above optical power lower limit means that the received optical power of the corresponding optical port is lower than -31dBm. Figure 4 As shown in the example, when line B 2765 is disabled to protect the first optical port, the received optical power of the 1-D optical port is lower than -31dBm.

[0073] Step S6: Summarize the automatic verification and acceptance results, archive and publish. The judgment results of the above steps are recorded in the corresponding acceptance database of the secondary intelligent operation and maintenance master station, and published to the secondary intelligent operation and maintenance Web user terminal for users to check and confirm, and handle abnormal alarms in time.

[0074] The embodiment of the present application provides a specific automatic verification method and system for optical fiber links in smart substations, which can automatically analyze the test results by remotely controlling the station-side process layer switch optical port enablement and monitoring the link signal in the station. The traditional optical fiber link acceptance working mode of repeatedly plugging and unplugging optical fibers on both sides of the device and the switch is changed, so that the station-side acceptance personnel do not need to carry out this cumbersome and inefficient acceptance project.

[0075] The embodiment of the present application also provides an automatic verification system for optical fiber links of smart substations. It should be noted that the intelligent operation and maintenance master station of the automatic verification system for optical fiber links of smart substations of the embodiment of the present application can be used to execute the automatic verification method for optical fiber links of smart substations provided in the embodiment of the present application.
