The intelligent Transformer substation with the chip protection adopts a network acquisition and network hopping mode, namely secondary analog quantities such as PT (Potential Transformer) and CT (Current Transformer) are connected to redundancy configuration GOOSE A1 and GOOSE A2 through merging units; and the protection device and the intelligent terminal are connected to the same network through the GOOSE A1 and the GOOSE A2, so that switching value acquisition, trip command transmission and the like are realized. Therefore, when the GOOSE of the chip protection device is interrupted, the chip protection device cannot acquire the fault quantity of the primary equipment and control the tripping function of the primary equipment circuit, so that when the GOOSE of the chip protection device is interrupted, the chip protection device loses the protection function, the safe operation of a power grid is influenced, and the chip protection device is required to be replaced frequently. The chip protection device realizes the unification of wiring and interfaces, can finish the compatibility and exchange between devices, improves the replacement speed of the protection device to a certain extent, but in the normal operation process of primary equipment, the chip protection device breaks down, still needs longer replacement and debugging time.

When the corresponding chip protection device GOOSE is interrupted, the problem that the protection function of the line is lost due to the interruption of the chip protection device GOOSE is solved by utilizing the rapid investment of the online standby protection device.
The instant standby method based on the intelligent substation chip protection device provided by the embodiment of the application can be applied to the application environment shown in fig. 1. The device manager 102 detects whether the GOOSE network of the chip protection device 108 and the GOOSE network of the intelligent terminal 104 are interrupted; when the device manager 102 detects that the GOOSE network of the chip protection device 108 is interrupted and the GOOSE network of the intelligent terminal 104 is not interrupted, analyzing the running state information sent by the intelligent terminal 104; when the device manager 102 determines that the primary device connected to the intelligent terminal 104 is in the operating state according to the operating state information, the backup file of the protection device for chip 108 is sent to the protection device for standby chip 106, so that the protection device for chip 108 is replaced by the protection device for standby chip 106 to perform the protection function. Specifically, the device manager 102, the intelligent terminal 104 and the chip protection device 108 may be all connected to a GOOSE network, so that the device manager 102 can monitor the operation conditions of the intelligent terminal 104 and the chip protection device 108. Meanwhile, the station control layer MMS network comprises a station control layer MMS C1 network and a station control layer MMS C2 network, wherein MMS (Manufacturing Message Specification) is a set of communication protocol for the industrial control system defined by ISO/IEC9506 standard. The device manager 102 is connected to a station control layer MMS C1 network and a station control layer MMS C2 network, and the chipization protection device 108 and the standby chipization protection device 106 are connected to any one of the station control layer MMS C networks. Further, the chip protection device 108 and the intelligent terminal 104 are divided according to intervals, that is, each chip protection device has its corresponding intelligent terminal, and the chip protection device 108 sends a trip command to the intelligent terminal 104 when detecting that a line fault occurs in a primary device according to a switching value signal of the primary device uploaded by the intelligent terminal 104, so as to protect the primary device connected to the intelligent terminal 104. The intelligent terminal 104 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers.
In one embodiment, as shown in fig. 2, an instant standby method based on a smart substation chip protection device is provided, which is described by taking the method as an example of being applied to the device manager in fig. 1, and includes the following steps:
step 202, detecting whether the GOOSE network of the chip protection device and the GOOSE network of the intelligent terminal are interrupted.
The GOOSE (Generic Object organized following Event) refers to a Generic Object Oriented Substation Event, and is a fast message transmission mechanism in IEC61850, and is used for transmitting important real-time signals between IEDs (Intelligent Electronic devices) in a Substation. The device manager establishes a communication mechanism with the intelligent terminal and the chip protection device through the GOOSE network, the intelligent terminal and the chip protection device can periodically and circularly send GOOSE heartbeat messages in a multicast mode, and the device manager can monitor the GOOSE heartbeat messages of the intelligent terminal and the chip protection device. In this embodiment, the GOOSE network includes a GOOSE A1 network and a GOOSE A2 network.
And 204, analyzing the running state information sent by the intelligent terminal when detecting that the GOOSE network of the chip protection device is interrupted and the GOOSE network of the intelligent terminal is not interrupted.
When the device manager detects that the GOOSE of the chip protection device is interrupted and detects that the intelligent terminal is not interrupted, the device manager analyzes the running state information of the primary device sent by the intelligent terminal. Specifically, the device manager determines that GOOSE A1 and GOOSE A2 of the protection device are interrupted simultaneously and continuously for a set duration, for example, for 2 minutes, it is determined that GOOSE of the protection device continues to be interrupted, so as to prevent interference caused by switching the standby protection device to operate during the restarting process of the protection device or interference signals. Or the device manager judges that the number of times of simultaneous interruption of the GOOSE A1 and the GOOSE A2 by the chip protection device within the preset time is greater than or equal to the set number of times, for example, 4 times of interruption occur within 3 minutes, which may be considered that the chip protection device frequently occurs interruption. When GOOSE A1 and GOOSE A2 of the chip protection device continue to be interrupted or are frequently interrupted, it is determined that GOOSE of the chip protection device is interrupted. When the GOOSE A1 and the GOOSE A2 of the chip protection device are simultaneously interrupted, the device manager may manually select and set the fault duration and the number of times of occurrence of faults within a certain time according to actual conditions.
And step 206, when the primary equipment connected with the intelligent terminal is judged to be in the running state according to the running state information, the backup file of the chip protection device is sent to the standby chip protection device, so that the standby chip protection device replaces the chip protection device to execute the protection function.
The backup files comprise all files which can enable the standby chip protection equipment to replace the chip protection device to execute the normal operation of the protection function. When the primary equipment connected with the intelligent terminal is judged to be in the running state according to the running state information, the equipment manager issues the backup file of the chip protection device to the standby chip protection device, and after the standby chip protection device acquires the backup file of the failed chip protection device, all information in the backup file is replaced and updated, so that complete replacement of the chip protection device and functions is realized.
According to the instant standby method based on the intelligent substation chip protection device, whether the GOOSE network of the chip protection device and the intelligent terminal is interrupted or not is judged, the running state information sent by the intelligent terminal is analyzed when the judgment result shows that the GOOSE network of the chip protection device is interrupted and the GOOSE network of the intelligent terminal is not interrupted, and then when the analysis result shows that the primary equipment is in the running state, the backup file of the chip protection device is sent to the standby chip protection device, so that the standby chip protection device replaces the chip protection device to execute the protection function, the protection reliability is improved, and the safe running of a power grid is guaranteed.
In one embodiment, the operation state information of the primary equipment connected with the intelligent terminal comprises a switch position signal and a disconnecting link position signal. Meanwhile, whether the primary equipment is in the running state or not is analyzed by combining the switch position signal and the disconnecting link position signal, and the detection is simple, convenient and quick.
The disconnecting link position signal comprises a line side disconnecting link position signal, a I female side disconnecting link position signal and a II female side disconnecting link position signal. Further, the step 204 of analyzing the operation state information sent by the intelligent terminal includes: and when at least one of the female side disconnecting links is in a closed position and the switch and the line side disconnecting link are in the closed position, judging that the primary equipment connected with the intelligent terminal is in an operating state. Specifically, if at least one of the female side disconnecting link I and the female side disconnecting link II is determined to be in the on position according to the switch position signal, the line side disconnecting link position signal, the female side disconnecting link I and the female side disconnecting link II, and both the switch and the line side disconnecting link are in the on position, the primary equipment is indicated to be in the running state.
In this embodiment, by introducing the content included in the operating state information of the primary device and setting the determination method when the primary device is in the operating state, the precondition for the standby chip protection device to be put into use is determined, and the reliability of the device is enhanced.
In one embodiment, prior to step 206, the method further comprises: and receiving backup information uploaded by the chip protection device, and saving the backup information as a backup file of the chip protection device according to the backup information.
The backup information comprises configuration information, fixed value list information and pressure plate state information. Specifically, the chip protection device initially uploads the initial configuration information, the fixed value list information and the pressing plate state information to the equipment manager in a backup file form, the equipment manager collects the backup files of all the chip protection devices and stores the backup files in different folders in a classified mode to form a device library. In addition, when any one of the configuration information, the fixed value list information or the pressing plate state information of the chip protection device changes, the chip protection device sends a backup starting command to the equipment manager, the equipment manager starts a backup function, and a file obtained by updating the information transmitted by the chip protection device is updated in a corresponding folder.
In this embodiment, the backup information of the protection device is sent to the device manager, and when any item of information in the backup information of the protection device changes, a backup command is sent to the device manager to update the backup information in time, so that the backup protection device can install the corresponding latest backup information in time when the protection device fails, thereby improving the reliability of the protection device.
In one embodiment, step 206 includes: when the primary equipment connected with the intelligent terminal is judged to be in the running state according to the running state information, whether the standby chip protection device is matched with the chip protection device or not is judged, and when the standby chip protection device is matched with the chip protection device, the backup file of the chip protection device is issued to the standby chip protection device.
The standby chip protection device is matched with the chip protection device, and the standby chip protection device can be matched with the chip protection device, including equipment models, related parameters and the like. Specifically, as shown in fig. 3, when the switch and the line side disconnecting link are in the on position and at least one of the I bus side disconnecting link and the II bus side disconnecting link is in the on position, it is determined that the primary device is in the operating state, and simultaneously the GOOSE of the chipized protection device is off, and neither GOOSE A1 nor GOOSE A2 of the intelligent terminal is off, the device manager starts a matching program to determine whether the standby chipized protection device is matched with the chipized protection device with a fault, and when it is determined that the standby chipized protection device is matched with the chipized protection device, the device manager downloads a backup file updated last time before the chipized protection device has the fault to the standby chipized protection device to replace the chipized protection device with the fault to operate. In addition, when a plurality of chipized protection devices fail, priority orders can be set for all the chipized protection devices through the equipment manager, and after the spare chipized protection device is confirmed to be matched with the chipized protection device with the failure through the matching program, the backup file of the chipized protection device with the highest priority degree is issued to the spare chipized protection device, so that the chipized protection device with the highest priority degree is replaced. After receiving the backup file, the standby chip protection device communicates with the intelligent terminal through the GOOSE A1 and the GOOSE A2 to replace the function of the failed chip protection device.
In this embodiment, when the GOOSE of the protection device is turned off and the primary device is in the operating state, the matching program is used to ensure that the standby protection device can be matched with the failed protection device, so as to reduce the risk of secondary failure caused by non-adaptive device after the failure of the protection device, and realize uninterrupted protection of the primary device.
In one embodiment, issuing the backup file of the chip protection device to the standby chip protection device includes: and the backup file of the chip protection device is sent to the standby chip protection device through the station control layer MMS network.

The chip protection device uploads the backup information to the equipment manager through the station control layer MMS C1 network, and the equipment manager sends the backup file to the standby chip protection device through the station control layer MMS C1 network. The station control layer MMS network is mainly used for information interaction between the device manager and MMS messages, wave recording files, fixed value files, archive files, alarm files, CID (Configured IED instance configuration file) and the like of the chip protection device.
In the embodiment, the backup file of the chip protection device is sent to the standby chip protection device through the station control layer MMS network, so that information interaction between the equipment manager and the chip protection device is realized, the backup file can be sent to the standby chip protection device immediately when the chip protection device breaks down, and the protection reliability is improved.
