[0027] Embodiment 1

[0028] Figure 1A flowchart of a method for identifying a safety measure ticket is provided for the first embodiment of the present invention. This embodiment is applicable to the case of identifying a safety measure ticket for a smart substation. The method can be executed by a safety measure ticket identification device. The safety measure ticket identification device can be implemented in the form of hardware and / or software. The safety measure ticket identification device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0029] S110. Determine the security measure items in the security measure ticket to be identified, and determine the security measure equipment elements and security measure object elements corresponding to the security measure items.

[0030] Among them, the safety measures ticket refers to the document of safety measures and operating procedures formulated for the maintenance work of the secondary system of the smart substation, which aims to clarify the safety requirements in the maintenance work of the secondary system, reduce the risk of accidents, and ensure the safety of personnel and equipment. Safety measures items usually refer to specific safety measures clearly listed in the safety measures ticket and formulated for specific risks or maintenance work.

[0031] Among them, the safety measure equipment element refers to the content related to the equipment or devices required to implement the safety measures. A safety measure equipment element is divided into the equipment type part, the voltage level part, the set part and the device description part. The safety measure object element refers to the content related to the object directly affected or protected by the safety measures. A safety measure object element is divided into the object type part and the object description part.

[0032] In the embodiment of the present invention, it can be understood that the safety measure items usually appear in the form of text descriptions in the safety measure ticket to be identified. Therefore, the text content in the safety measure ticket to be identified can be extracted, and the safety measure items, as well as the safety measure equipment elements and safety measure object elements corresponding to the safety measure items can be determined based on the extracted text content. By determining the safety measure equipment elements and safety measure object elements corresponding to the safety measure items, it is helpful to determine the actual safety measure equipment that executes the safety measure items in the substation, and then determine the signal reference corresponding to the safety measure items, and establish an association relationship between the safety measure ticket to be identified and the status signal of the actual safety measure equipment.

[0033] S120: Determine the actual safety measure device corresponding to the safety measure item according to the predetermined safety measure device information and safety measure device elements.

[0034] The predetermined safety measure equipment information includes relevant information of all intelligent electronic devices in the substation that may execute safety measure items, such as equipment type, voltage level, bay type, set, and branch information. The equipment type may be line protection, main transformer protection, busbar protection, etc. The voltage level may be 20Kv, 35kV, 750kV, etc. The bay type may be line bay, main transformer bay, busbar bay, etc. The set includes the first set, the second set, etc. The actual safety measure equipment is the intelligent electronic device that actually executes the safety measure items.

[0035] In the embodiment of the present invention, the actual safety measure device corresponding to the safety measure entry can be determined according to the predetermined safety measure device information and the safety measure device element. Specifically, the device type, voltage level, set, etc. in the safety measure device information can be matched with the device type part, voltage level part, set part, etc. in the safety measure device element, and the actual safety measure device corresponding to the safety measure entry can be determined from the intelligent electronic devices in the substation.

[0036] Optionally, the process of predetermining safety measure equipment information includes: determining the equipment type, voltage level, bay type, set and branch information of each intelligent electronic device in the substation as safety measure equipment information according to the substation configuration description file.

[0037] In an embodiment of the present invention, the device type, voltage level, bay type, set, and branch information of each intelligent electronic device in the substation can be determined according to the substation configuration description SCD file containing the configuration information of all devices in the substation, and used as the safety measure device information. By determining the safety measure device information according to the substation configuration description file, the comprehensiveness and accuracy of the obtained safety measure device information can be improved, and at the same time, compared with the traditional manual method, the work efficiency is improved.

[0038] S130: Determine a signal reference corresponding to the safety measure entry according to the actual safety measure equipment, the safety measure object element, and the predetermined safety measure signal reference information.

[0039] Among them, the safety measure signal reference information is used to describe the types of signal references of all intelligent electronic devices in the substation that may execute safety measure items. Signal reference refers to the reference and identification of various types of signals in the substation, and its types include sampling value SV receiving soft pressure plate, substation event GOOSE sending soft pressure plate for general objects, substation event GOOSE receiving soft pressure plate for general objects, optical fiber information, telemetry and telesignaling, etc.

[0040] In an embodiment of the present invention, the safety measure signal reference information corresponding to the actual safety measure device can be determined from the predetermined safety measure signal reference information including the signal reference types of all intelligent electronic devices, and then the signal reference corresponding to the safety measure item can be determined according to the safety measure signal reference information corresponding to the actual safety measure device and the safety measure object element, so as to complete the identification of the safety measure ticket to be identified. Through the above steps, the safety measure ticket can be identified quickly and accurately, avoiding the writing of a large number of electronic safety measure tickets, facilitating large-scale promotion, and having important significance for strengthening the safe and stable operation of the power grid.

[0041] Optionally, the process of predetermining safety measures signal reference information includes: traversing the data sets of each intelligent electronic device in the substation, and determining the descriptive information of the signal reference of the intelligent electronic device in the data set; dividing the signal reference into a sampling value receiving soft pressure plate, a general object-oriented substation event sending soft pressure plate, a general object-oriented substation event receiving soft pressure plate, optical fiber information, telemetry and telesignaling according to the descriptive information as safety measures signal reference information.

[0042] In an embodiment of the present invention, the data sets of various intelligent electronic devices in the substation can be traversed, and the signal references of the intelligent electronic devices can be divided into SV receiving soft pressure plate, GOOSE sending soft pressure plate, GOOSE receiving soft pressure plate, optical fiber information, telemetry and telesignaling according to the description information of the signal references of the intelligent electronic devices in the data set, and used as safety measures signal reference information.

[0043] The technical solution of the embodiment of the present invention determines the security measure items in the security measure ticket to be identified, and determines the security measure equipment elements and security measure object elements corresponding to the security measure items; determines the actual security measure equipment corresponding to the security measure items based on the predetermined security measure equipment information and the security measure equipment elements; determines the signal reference corresponding to the security measure items based on the actual security measure equipment, the security measure object elements and the predetermined security measure signal reference information. The technical solution of the embodiment of the present invention can automatically complete the rapid and accurate identification of the security measure tickets to be identified, and improve the correctness and efficiency of the security measures work by extracting the security measure elements in the security measure ticket to be identified, and determining the signal reference corresponding to the security measure items in combination with the predetermined security measure information.

[0044] Embodiment 2

[0045] Figure 2 This is a flowchart of a security measure ticket identification method provided by the second embodiment of the present invention. The embodiment of the present invention is optimized based on the above embodiment. For solutions not described in detail in the embodiment of the present invention, please refer to the above embodiment. Figure 2 As shown, the method includes:

[0046] S210. Determine the security measure entry in the security measure ticket to be identified according to the table structure of the security measure ticket to be identified; wherein the security measure entry includes a security measure parent entry and a security measure child entry.

[0047] In the embodiment of the present invention, the security measure ticket to be identified is in the form of a table, so the security measure items in the security measure ticket to be identified can be determined according to the table structure of the security measure ticket to be identified. Specifically, the security measure ticket to be identified is a complete table, and a cell in the table with "execution" and "recovery" cells on the left and right is determined as a security measure sub-item, and a cell in the table that occupies a row and does not meet the judgment conditions of the cell corresponding to the security measure sub-item is determined as a security measure parent item, which is the security measure parent object of the security measure sub-items between the subsequent security measure parent items and the next security measure parent item.

[0048] S220. Determine a signal object in the safety measure entry, and determine a safety measure device element corresponding to the safety measure entry according to the signal object.

[0049] Among them, the security measure entry may be composed of one or more signal objects, and a signal object is composed of multiple elements. The multiple elements must include a security measure action element and a security measure object element, as well as one of a security measure parent object element and a security measure device element.

[0050] In an embodiment of the present invention, after determining the signal object in the security measure entry, the security measure device element corresponding to the signal object in the security measure entry can be determined first, and then the security measure device element corresponding to the security measure entry can be determined based on the security measure device element corresponding to the signal object. It should be noted that if the signal object of a security measure entry does not include the corresponding security measure device element but includes the corresponding security measure parent object element, the security measure device element of the parent entry of the security measure entry can be determined as the security measure device element corresponding to the security measure entry.

[0051] Optionally, determine the signal object in the security measures entry, and determine the security measures equipment element corresponding to the security measures entry based on the signal object, including: determine the security measures action element in the security measures entry, and identify the signal object in the security measures entry based on the security measures action element; for each signal object, determine the security measures equipment element corresponding to the signal object; determine the security measures equipment element corresponding to the security measures entry based on the security measures equipment element corresponding to the signal object.

[0052] Among them, the security measure object element refers to the content related to the actions that need to be completed by the security measure. The security measure object element is divided into detection type and operation type. The operation type is divided into sub-type and combined type.

[0053] In the embodiment of the present invention, each security measure action element included in the security measure entry represents that the security measure entry has a signal object. Therefore, the signal object in the security measure entry can be identified by determining the security measure action element in the security measure entry. Determining the security measure action element in the security measure entry specifically includes: using the regular expression (check)|(check)|(verify)|(check) to determine the detection type of security measure action element, using the regular expression (exit)|(separate)|(disconnect)|(open)|(set to 0)|(split)|(remove)|(unplug)|(pull out)|(cut open) to determine the classification type of security measure action element, and using the regular expression (put in)|(close)|(connect)|(connect)|(set to 1)|(close)|(access)|(plug in)|(put in) to determine the combination type of security measure action element. Afterwards, the signal objects in the security measures entry can be identified according to the security measures action elements, and for each signal object, the security measures equipment elements corresponding to the signal objects can be determined. Finally, the security measures equipment elements corresponding to the security measures entry can be determined according to the security measures equipment elements corresponding to the signal objects.

[0054] Optionally, for each signal object, determine the safety measures equipment element corresponding to the signal object, including: identifying the equipment type part, voltage level part, set part and equipment description part in the signal object in text order as the safety measures equipment element of the signal object; if multiple safety measures equipment elements are identified in a signal object, the first safety measures equipment element identified in the text order is used as the safety measures equipment element of the signal object.

[0055] In an embodiment of the present invention, the device type part, voltage level part and set part in the signal object can be identified by regular expressions. For example, the line protection part in the device type part can be identified by (PL)|(line.* protection)|(optical fiber longitudinal differential protection)|([^bus] line.* protection), the 35kV part in the voltage level part can be identified by 35[kK][Vv], the first set part in the set part can be identified by (X$)|(first set)|(A set)|(main one)|(protection A)|([^A-Za-z]A[^A-Za-z])|(No. 1 (?! main transformer)), etc. After that, the remaining parts except the device type part, voltage level part and set part are used as the device description part. It should be noted that a signal object has one and only one safety measure device element. Therefore, if multiple safety measure device elements are identified in a signal object, the first safety measure device element identified in text order is used as the safety measure device element of the signal object.

[0056] S230. Determine the object type part of the security measure entry by using a regular expression, extract the object description part of the security measure entry, and use the object type part and the object description part as security measure object elements of the security measure entry.

[0057] Among them, the object types include SV receiving soft pressure plate, GOOSE sending soft pressure plate, GOOSE receiving soft pressure plate, optical fiber information, telemetry and telesignaling.

[0058] In the embodiment of the present invention, the object type part of the safety measure entry can be determined by a regular expression. For example, the SV receiving soft pressure plate can be identified by (SV.*soft pressure plate)|(SV receiving soft pressure plate)|(interval receiving soft pressure plate), and the remote signal can be identified by (device power supply)|(power supply circuit breaker)|(control.*power supply)|(operating power supply), etc. After that, other elements in the signal object in the safety measure entry can be excluded, and the content of the remaining part can be extracted as the object description part of the safety measure entry, and the object type part and the object description part are used as the safety measure object elements of the safety measure entry.

[0059] S240. Filter out candidate devices having the same device type, voltage level and set as those of the safety measures equipment elements from the intelligent electronic devices of the substation according to the safety measures equipment information.

[0060] In an embodiment of the present invention, after obtaining the safety measures equipment element corresponding to the safety measures entry, intelligent electronic devices with the same equipment type part, voltage level part and set part as the safety measures equipment element can be screened out from all the intelligent electronic devices in the substation according to the safety measures equipment information as candidate devices for the actual safety measures equipment.

[0061] S250. If the candidate device is a non-main transformer device, the interval type and branch information of the candidate device are respectively matched with the device description part of the safety measure device element to obtain a first similarity matching result, and the actual safety measure device is determined according to the first similarity matching result.

[0062] In the embodiment of the present invention, if the candidate device is a non-main transformer device, the interval type and branch information of the candidate device can be respectively matched with the device description part of the safety measure device element to obtain a first similarity matching result. Afterwards, the actual safety measure device can be determined based on the first similarity matching result. Specifically, if any one of the interval type and branch information of the candidate device has a 100% similarity with the device description part of the safety measure device element, the candidate device is used as the actual safety measure device. It should be noted that there may be multiple actual safety measure devices obtained here, and they are not unique.

[0063] S260: If the candidate device is a main transformer device, extract the main transformer sequence number of the safety measure device element, match it with the main transformer sequence number of the candidate device, and determine the actual safety measure device according to the main transformer sequence number matching result.

[0064] In the embodiment of the present invention, if the candidate device is a main transformer device, the main transformer sequence number of the safety measure device element can be extracted through the positive side expression, and the main transformer sequence number of the safety measure device element is matched with the main transformer sequence number of the candidate device to obtain the main transformer sequence number matching result. Afterwards, the actual safety measure device can be determined according to the main transformer sequence number matching result. Specifically, the candidate device whose main transformer sequence number is the same as the main transformer sequence number of the safety measure device element can be used as the actual safety measure device. At this time, the actual safety measure device obtained is uniquely determined.

[0065] S270. Determine the signal reference type of the actual safety measure device according to the safety measure signal reference information, and eliminate the actual safety measure device whose signal reference type does not match the object type part in the safety measure object element, to obtain the target safety measure device.

[0066] In an embodiment of the present invention, when multiple actual safety measures devices are obtained, the signal reference type of each actual safety measures device can be determined respectively according to the safety measures signal reference information, and the actual safety measures devices whose signal reference types do not match the object type part in the safety measures object element can be eliminated to obtain the target safety measures device, so as to further narrow the scope of the actual safety measures devices, reduce the subsequent calculation amount, and improve the accuracy of the calculation.

[0067] S280. If the target safety measure device is uniquely determined, perform similarity matching on the object description part in the safety measure object element and the description information of the signal reference of the target safety measure device to obtain a second similarity matching result, and determine the signal reference corresponding to the safety measure entry according to the second similarity matching result.

[0068] In the embodiment of the present invention, if the target safety measure device is uniquely determined, the object description part in the safety measure object element and the description information of the signal reference of the target safety measure device can be matched for similarity, and the similarity between the object description part in the safety measure object element and each signal reference in the description information of the signal reference of the target safety measure device can be obtained as the second similarity matching result. Afterwards, the signal reference corresponding to the safety measure entry can be determined according to the second similarity matching result, specifically, the signal reference with the highest similarity to the object description part in the safety measure object element is taken as the signal reference corresponding to the safety measure entry.

[0069] Optionally, before the object description part of the safety measure object element is matched with the description information of the signal reference of the target safety measure device for similarity, all characters representing digital meanings in the description information and the object description part can be replaced with a unified expression using a regular expression, such as replacing [zero] with 0, and replacing the relevant content in the description information and the object description part according to the type of the target safety measure device. Specifically, when the target safety measure device is a busbar device, the following content in the description information and the object description part is replaced with a regular expression: (branch 1|bus coupler [1]?) is replaced with branch 1; (branch 2|bus coupler 2|segment|segment 1) is replaced with branch 2; (branch 3|segment 2) is replaced with branch 3; (branch 4|[^0-9]?[1]?[^0-9]?main transformer [^0-9]?[1] ? [^0-9]? ) is replaced with branch 4; (branch 14|[^0-9]?[3]?[^0-9]?main transformer[^0-9]?[3]?[^0-9]?) is replaced with branch 5; (branch 15|[^0-9]?[4]?[^0-9]?main transformer[^0-9]?[4]?[^0-9]?) is replaced with branch 6; (branch|line)\d+ is replaced with branch\d+. In addition, if the description information and object description parts contain the interval type of the target safety measure device, the description of the interval type in both is replaced with the branch information of the target safety measure device. When the target safety measure device is a main transformer device, if the voltage level part (\d+[kK][Vv]) is identified in the description information and object description parts, it is replaced with the high voltage side, medium voltage side, and low voltage side according to the size of each voltage level from large to small. When the target safety measure device is other devices, if the description information and the object description part contain the interval type of the target safety measure device, the description of the interval type in both parts is replaced with the interval type of the target safety measure device.

[0070] S290. If there are at least two target security measures devices, for each target security measures device, perform similarity matching between the object description part in the security measures object element and the description information of the signal reference of the target security measures device to obtain a third similarity matching result, assign different weights to the first similarity matching result and the third similarity matching result, and determine the signal reference corresponding to the security measures entry based on the weighted sum of the first similarity matching result and the third similarity matching result.

[0071] In the embodiment of the present invention, if there are at least two target safety measure devices, the similarity between the object description part in the safety measure object element and each signal reference in the description information of the signal reference of each target safety measure device can be obtained for each target safety measure device according to the method in step S280 as the third similarity matching result. Afterwards, different weights can be assigned to the first similarity matching result and the third similarity matching result, and the weighted summation result of the first similarity matching result and the third similarity matching result can be determined, and the signal reference corresponding to the safety measure entry can be determined according to the weighted summation result. Specifically, the signal reference corresponding to the largest weighted summation result is taken as the signal reference corresponding to the safety measure entry.

[0072] The technical solution of the embodiment of the present invention determines the safety measure entry in the safety measure ticket to be identified according to the table structure of the safety measure ticket to be identified; wherein the safety measure entry includes a safety measure parent entry and a safety measure child entry; determines the signal object in the safety measure entry, and determines the safety measure equipment element corresponding to the safety measure entry according to the signal object; judges the object type part of the safety measure entry by a regular expression, and extracts the object description part of the safety measure entry, and uses the object type part and the object description part as the safety measure object element of the safety measure entry; selects candidate devices that are the same as the equipment type part, voltage level part and set part of the safety measure equipment element from the intelligent electronic devices of the substation according to the safety measure equipment information; if the candidate device is a non-main transformer device, performs similarity matching on the interval type and branch information of the candidate device and the equipment description part of the safety measure equipment element respectively, obtains a first similarity matching result, and determines the actual safety measure device according to the first similarity matching result; if the candidate device is a main transformer device, extracts the main transformer sequence number of the safety measure equipment element, and compares it with the candidate The main transformer serial number of the equipment is matched, and the actual safety measure equipment is determined according to the main transformer serial number matching result; the signal reference type of the actual safety measure equipment is determined according to the safety measure signal reference information, and the actual safety measure equipment whose signal reference type does not match the object type part in the safety measure object element is eliminated to obtain the target safety measure equipment; if the target safety measure equipment is uniquely determined, the object description part in the safety measure object element is matched with the description information of the signal reference of the target safety measure equipment for similarity to obtain a second similarity matching result, and the signal reference corresponding to the safety measure entry is determined according to the second similarity matching result; if there are at least two target safety measure equipment, for each target safety measure equipment, the object description part in the safety measure object element is matched with the description information of the signal reference of the target safety measure equipment for similarity to obtain a third similarity matching result, different weights are assigned to the first similarity matching result and the third similarity matching result, and the signal reference corresponding to the safety measure entry is determined according to the weighted sum result of the first similarity matching result and the third similarity matching result. The technical solution of the embodiment of the present invention can automatically complete the rapid and accurate identification of the security measure ticket to be identified, thereby improving the accuracy and efficiency of the security measure work, by extracting the security measure elements in the security measure ticket to be identified and combining them with the predetermined security measure information to determine the signal reference corresponding to the security measure entry.
