[0052] Figure 1 A flowchart of a method for identifying an operation mode sheet of a main network side provided by an embodiment of the application;

[0053] Figure 2 A structural diagram of an identification device for an operation mode sheet of a main network side provided by an embodiment of the application. DETAILED DESCRIPTION

[0054] In order for those skilled in the art to better understand the application scheme, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0055] For ease of understanding, please refer to Figure 1 An embodiment of a method for identifying an operation mode sheet of a main network side provided by the application includes the following steps.

[0056] Step 101: performing first preprocessing operation on the current operation mode sheet of the main network side based on preset semantic rules to obtain a plurality of semantic single sentences, the first preprocessing operation including semantic information definition, description correction, and single sentence segmentation.

[0057] Further, step 101 includes the following steps.

[0058] Performing semantic information definition on the current operation mode sheet of the main network side based on preset semantic rules to obtain invalid characters, segmentation symbols, and device characteristics.

[0059] Performing description correction on the content of the current operation mode sheet according to the device characteristics to obtain a standard operation mode sheet.

[0060] Performing single sentence segmentation operation on the standard operation mode sheet through the segmentation symbols to obtain a plurality of semantic single sentences.

[0061] The main grid side of the power grid is described in some text rules. Some words that do not need to be recognized can be defined according to these unique rules, and these words are defined as invalid characters, such as "verification", "has", "ground", "reclosing", "hot standby", "cold standby", "tower", "loop", "please notify", "coordination", "relay protection", "backup", "have", "management", "check", "confirmation", "cold lead", "hot lead", "reserve", "same", etc. Other characters can also be added according to the characteristics of the mode sheet. The specific limitations are not limited.

[0062] The division symbol is used to divide the sentence in the mode sheet, such as "\n", ",", ".", ";", "!", "?", ",", ";", "!", "?", etc. Other sentence symbols can also be added, which are not limited here.

[0063] The device feature is mainly the description of the device, such as "station", "factory", "line", "main transformer", "A", "B", "#", "M", "B", "kv", "kV", "kV", "switch", "knife", "segment", etc.

[0064] For invalid characters in the mode sheet, they need to be deleted, such as deleting the explanation or note content in the parentheses, deleting space characters, and additionally deleting the description content after the voltage level and "attention" of the modified line and substation. Deleting these information can extract more concise word information, which can improve the accuracy of the recognition result.

[0065] The device feature information can be used for content correction of the mode sheet, preventing the original mode sheet description from having ambiguity, mistakes, etc. Specifically, the case where the line names "A, B, C, and D" are mixed together without being separated by a comma is replaced by "A, B, C, and D". For example, Taohe A and B lines are corrected to Taohe A and B lines. Since the case where "line" and "station" can be omitted can occur, the "line" and "station" of the line and the transformer substation are completed. Understandably, the line is completed first to prevent the branch line from being replaced by the station. The problem of incorrect expression of M2 and M3 (bus names) or 2# and 3# (main transformer names) is solved. Based on the regular expression, fuzzy matching is performed, and correction is performed. For example, M2 and M3 or 2# and 3# are respectively corrected to 2M and 3M or #2 and #3. The problem of 2M and 3M or #2 and #3 being connected together without a separator is solved. For example, 2M and 3M are corrected to 2M and 3M. The case of multiple buses and switch modification is solved, and the bus name is removed. For example, XX station 110 kV 5M and 6M bus tie 110 switch, XX station 110 kV 2M and 5M section 115 switch, are respectively corrected to XX station 110 switch and XX station 115 switch. The case of line modification of the switch is solved, and the line name is removed. For example, XX station Taohe B line 155 switch is corrected to XX station 155 switch. The case of 220 kV and 110 kV buses modified by multiple voltage levels is solved. For example, XX station 220 kV and 110 kV bus parallel operation is corrected to XX station 220 kV bus and XX station 110 kV bus parallel operation. The bus connection device separated by a comma is identified. For example, XX station 110 kV bus is reversed to the following mode: #1 bus: #3 transformer, A line, B line, C line, D line, E line, and F line. It is identified that XX station 110 kV 1M bus is connected to XX station #3 main transformer, A line, B line, C line, D line, E line, and F line.

[0066] The text in the corrected mode sheet can be divided into multiple semantic single sentences by the defined segmentation character, to obtain preliminary to-be-recognized text data.

[0067] In step 102, action recognition is performed on the semantic single sentence according to a first regular expression, to obtain an action mode list.

[0068] The regular expression is also a rule expression, which can retrieve and replace some text that meets a certain pattern or rule. Based on this, the action mode in the semantic single sentence can be identified. If no action mode can be identified, it is considered as an invalid action, and subsequent identification is not needed.

[0069] The identification rule can be set according to the text features, such as "(operation / execution / turn off) … (by / from) … (turn off / turn over / turn off / turn over)", "turn … (to / into / lead to) … (side operation / operation / side)", "(by / in / adjust to / turn to) … (side charging operation / side charging / charging operation / charging) (to) … (side loop / loop)", "(use) … (by / via / through / by) … series supply … supply …" and the like.

[0070] In step 103, a second preprocessing operation is performed on the action mode list to obtain a simplified action mode list, and the second preprocessing operation includes number deletion, substation completion, device name unification and time text removal.

[0071] Further, in step 103, the following steps are included:

[0072] The head number in the action mode list is deleted to obtain a number-free action mode.

[0073] Based on the cosine similarity, the substation completion operation is performed on the device in the number-free action mode to obtain a repaired action mode.

[0074] Based on the standard power grid terms, the device name in the repaired action mode is uniformly expressed to obtain a standardized action mode.

[0075] The time text in the standardized action mode is removed to obtain a simplified action mode list.

[0076] Deleting the head number means deleting the initial capitalization sequence number in the mode sheet, such as one, two, three, or 1, 2, 3, etc., to prevent the number sequence from affecting the extraction of the device name. What needs to be completed is the substation to which the device belongs, that is, the device name without substation modification needs to be added to the substation. It may be that the device substation is also mistakenly deleted because unnecessary content is deleted. Therefore, each sentence is generated into a high-dimensional vector with the same dimension; then, the cosine similarity of each vector is calculated to find the original text that is mistakenly deleted, so as to locate the substation name in the original position of the mode sheet. The dimensions of different vectors are the same, so the cosine distance can be calculated for similarity comparison.

[0077] The standard power grid terms can be defined according to different noun classes, for example, the single temperature of voltage level is unified as "kV" unit from "kilo-volt", "KV", "kv", "Kv", "kV". Taking the second number as an example, the main transformer is unified as "XX station #2 main transformer". The main mode of time text is year / month / day / hour / minute information. The action mode in the simplified action mode list is expressed as: ['xxx power outage', 'xxx supply xxx', 'xxx supply xxx through xxx', 'xxx supply xxx through xxx from xxx', 'xxx string supply xxx', 'xxx string supply xxx through xxx', 'xxx string supply xxx supply xxx', 'xxx string supply xxx supply xxx through xxx', 'xxx parallel', 'xxx parallel supply power to xxx', 'xxx parallel supply power from xxx', 'xxx split column', 'xxx split column supply power to xxx', 'xxx split column supply power from xxx', 'close xxx', 'disconnect xxx', 'xxx connect xxx'].

[0078] Step 104, word division operation is performed on the sentences in the simplified action mode list to obtain a plurality of segmented words.

[0079] The action mode in the simplified action mode list is relatively clear, and each action noun and device can be quickly divided to obtain a plurality of segmented words for subsequent device recognition.

[0080] Step 105, based on the segmented words and the preset main grid side information, the device is identified according to the second regular expression to obtain the device ID.

[0081] The preset main grid side information includes the completed information and the unified name information. The regular expression of the SQL statement can be used to identify the device ID in the segmented words according to the constraint conditions of different device types to obtain the device ID information.

[0082] Step 106, based on the preset power grid topology relationship, the target action information is determined according to the action mode list and the device ID.

[0083] Further, step 106 includes:

[0084] Obtain the preset power grid topology relationship between the devices according to the preset device topology relationship table;

[0085] Obtain the power flow direction and switch state of the devices in the preset power grid topology relationship from the preset device load table and the preset device state table;

[0086] Perform device power flow influence analysis according to the power flow direction, switch state, action mode list and device ID to determine the target action information.

[0087] The topological connection relationship between power grid devices can be acquired from the preset device topological relationship table. The power flow direction of the device, the opening and closing state of the switch and other information can be acquired from the preset device load table and the preset device state table. Based on the time sequence of the single mode power outage and power restoration, the device affected by the current mode and the current time is analyzed. Then, according to the device load, the switch opening and closing state and other state data, the affected device is subjected to corresponding action. Finally, the action mode and the device ID in the mode sheet are accurately identified and searched.

[0088] The method for identifying the main grid side operation mode sheet provided in the embodiments of the present application can arrange the text information in the mode sheet through a plurality of preprocessing operations, gradually identify the action mode in the mode sheet, and simplify the sentence description, so that the words and sentences to be identified are as much effective information as possible, thereby accurately identifying the device ID of the operation and obtaining complete target action information. The method is not affected by the lack of unified standards in the mode sheet writing, only focuses on the important identification words and sentences, and can correct non-standard key information, thereby ensuring the reliability of the identification result. Therefore, the embodiments of the present application can solve the technical problem that the prior art lacks a text recognition scheme for the mode sheet.
