Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power systems, in particular to a method for realizing automatic double confirmation of a soft panel of a smart substation "one-key sequential control". BACKGROUND

[0002] With the proposal of the national "3060" double carbon target and the steady progress of the construction of new power systems, the existing operation mode of smart substations is increasingly unable to meet the efficiency requirements under the new situation. Taking the operation of a 110kV smart substation with 110kV incoming lines and busbars and a main transformer changed from operation to cold standby as an example, there are a total of 71 operation tasks, and all manual operations take about two hours. At the same time, due to the large number of operation steps, it is easy to miss or make mistakes in actual manual operation. Therefore, the existing operation of smart substations needs to improve efficiency and liberate manpower on the monitoring host or dispatching master station.

[0003] "One-key sequential control" is to solidify a large number of and tedious manual switching operation steps on a special background computer. As long as the required "operation task" is clicked on the computer, the computer can automatically complete a series of device remote control operations, and can also automatically verify whether the operation is in place to ensure the correctness of the operation. At present, the "one-key sequential control" automatic double confirmation of primary devices can be realized in smart substations by using microswitch technology. However, the "one-key sequential control" operation in this mode has the problem of limited scope of application, and cannot well adapt to the operation involving protection device soft panel remote control and other protection state switching. The remote control of the protection soft panel of the smart substation currently adopts the mode of remote signaling information and manual checking and confirmation of the protection device, which is low in work efficiency and easy to make mistakes, and cannot meet the requirements of "one-key sequential control" information automatic double confirmation. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be understood that in the various embodiments of the present invention, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0023] It should be understood that in this invention, "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0024] The technical solution of the present invention will be described in detail below with reference to specific embodiments. Embodiments may be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0025] Example:

[0026] like Figure 1 The diagram illustrates a method for automatic dual confirmation of a "one-click sequential control" soft pressure plate in an intelligent substation, comprising the following steps:

[0027] S1: Pre-configure the first and second acquisition devices;

[0028] S2: The first acquisition device and the second acquisition device respectively acquire the first confirmation information containing the remote signaling information of the soft pressure plate and the second confirmation information containing the status of the soft pressure plate;

[0029] S3: The collected first confirmation information and the second confirmation information are checked, if the information checking result meets a preset state, the operation precondition is confirmed, the one-key sequence control operation can be performed, otherwise, it is considered that the operation precondition is not confirmed, and the one-key sequence control operation cannot be performed;

[0030] S4: After confirming the operation precondition, if a one-key sequence control operation request is received, the one-key sequence control operation is performed.

[0031] As shown in Figure 2 In the embodiment, the first acquisition device is a main transformer protection, the second acquisition device is a signal substation, the station control layer network switch is connected with the signal substation, the main transformer protection and the monitoring host through RJ45 network lines, and the MMS communication protocol of DL / T860 standard is used. The signal substation is developed specially (the signal substation has the function of communicating with the monitoring host 104 message, and can be used as the device for the second confirmation information source of the soft pressure plate one-key sequence control operation). It should be noted that in the actual intelligent substation, the signal substation can be used, or other devices with similar functions can be used. The IP address of the monitoring host is configured as 192.168.1.10, the IP address of the signal substation is configured as 192.168.1.11, and the IP address of the main transformer protection is configured as 192.168.1.101.

[0032] The monitoring host communicates with the main transformer protection through the MMS protocol, and uses the remote signaling information of the main transformer protection to send a message as the first confirmation information of the soft pressure plate one-key sequence control operation of the monitoring host. According to the configuration requirements of the MMS communication protocol, the monitoring host is configured with an instance number 01.

[0033] The signal substation communicates with the main transformer protection through the MMS protocol, and communicates with the monitoring host through the 104 protocol. The signal substation uses the MMS protocol remote signaling information of the main transformer protection to send a message to accept the soft pressure plate state information, and uses the 104 protocol single-point remote signaling message to send the soft pressure plate state of the main transformer protection to the monitoring host as the second confirmation information of the soft pressure plate one-key sequence control operation of the monitoring host. According to the configuration requirements of the MMS communication protocol, the signal substation is configured with an instance number 05.

[0034] The active sending of the soft pressure plate remote signaling state uses the Read service of the MMS protocol (corresponding to the GetBRCBValue service of DL / T860), and the active calling uses the FileRead service of the MMS protocol (corresponding to the GetFile service of DL / T860).

[0035] After the monitoring host receives the first and second confirmation information of the soft pressure plate, the monitoring host automatically judges whether the soft pressure plate state is the final state required by the sequence control operation step through the configured one-key sequence control module.

[0036] The first and second confirmation information of the present example has four differences: (1) the physical network of the monitoring host and the protection substation is different, (2) the network layer IP address of the monitoring host and the protection substation is different, (3) the application layer instance number of the monitoring host and the protection substation is different, and (4) the device form of the monitoring host and the protection substation is different.

[0037] The present embodiment can greatly compress the operation time of the smart substation, and can eliminate the possible error operation in the operation. The operation time of the 110kV smart substation 110kV incoming line with bus and main transformer from operation to cold standby and other types of operation involving primary equipment and soft pressure plate can be compressed to about 25% of the manual operation time, and the operation time of the 110kV spare automatic switching and other types of pure soft pressure plate can be compressed to about 10% of the manual operation time.

[0038] The substantial effects of the present application include: the state conversion programmed control of the protection device of the smart substation can be realized, the applicability of the "one-key sequence control" technology in the smart substation operation can be improved through the fusion of the primary equipment "one-key sequence control" automatic double confirmation, the operation time of the smart substation can be greatly compressed, and the possible error operation in the operation can be eliminated.
