Description

Technical Field

[0001] The present invention relates to the technical field of power grid dispatching, and in particular to a system and method for evaluating the operational standardization of power grid dispatching services. Background Art

[0002] With the rapid development of the power industry and the in-depth promotion of smart grid construction, the country has put forward higher requirements for the capacity and operational norms of power grid dispatching business. Therefore, it is of great theoretical and practical significance to determine the behavioral norms of power grid dispatching business, optimize dispatching to improve the response speed and decision-making efficiency of power grid dispatching, ensure the safe and stable operation of the power grid, and further improve the dispatching safety operation level of the power grid.

[0003] At present, power grid companies mainly rely on traditional experience and methods to perform dispatching tasks. In terms of dispatching business, there is a lack of effective dispatching business behavior process standard reminders, it is difficult to match the historical process of business scenarios, and there is a lack of a unified dispatching business progress query and display platform. Summary of the invention

[0004] The purpose of the present invention is to provide a power grid dispatching business operation standardization evaluation system in view of the defects of the prior art, including:

[0005] The power dispatching business operation specification extraction module builds a business name keyword set according to the names of all power dispatching businesses, retrieves all business name keywords in the business name keyword set in the power dispatching business specification document, and uses the context of each retrieved business name keyword as the standard operation steps of the corresponding business under the corresponding business name keyword, and obtains the power dispatching business operation specification set according to the business name corresponding to each business name keyword and the standard operation steps of the corresponding business;

[0006] The electric power dispatching business operation evaluation module calculates the similarity between the actual electric power dispatching business operation steps and the operation specification formula of the corresponding business in the electric power dispatching business operation specification formula set, and determines whether the actual electric power dispatching business operation steps are compliant based on the similarity calculation score.

[0007] Furthermore, in the power dispatching business operation specification extraction module, the specific method of retrieving the context of each business name keyword in the power dispatching business specification document as the standard operation steps of the business corresponding to each business name keyword is:

[0008] The electric power dispatching business regulatory document is segmented into Chinese words, and each business name keyword is constructed into a regular expression. The regular expression is used to retrieve the context of each business name keyword in the electric power dispatching business regulatory document after Chinese word segmentation, and the context is used as the standard operation steps of the business corresponding to each business name keyword. The scope of the context is between two periods.

[0009] Furthermore, in the power dispatching business operation specification extraction module, the specific method of obtaining the power dispatching business operation specification set according to the business name corresponding to each business name keyword and the standard operation steps of the corresponding business is:

[0010] The standard operation steps are decomposed into standard operation step formulas consisting of Chinese text and numbers in the form of step 1, step 2, ..., step n. The business name and the standard operation step formulas of the corresponding business are organized into a power dispatching business operation standard formula set in the following form: [business name | standard step 1, standard step 2, ..., standard step n].

[0011] Furthermore, in the power dispatching business operation evaluation module, before calculating the similarity between the actual power dispatching business operation steps and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, the actual power dispatching business operation steps are first converted into a power dispatching business standard text that is the same as the Chinese text of the standard step n in the operation step specification formula, expressed as follows: [Business name|Standard step 1, Standard step 2,…, Standard step n], where the numbers in the standard step n are the numbers involved in the actual power dispatching business operation steps.

[0012] Furthermore, in the power dispatching business operation evaluation module, the actual power dispatching business operation steps are similarly calculated with the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, and the specific steps of determining whether the actual power dispatching business operation steps are compliant according to the similarity calculation score are as follows:

[0013] Regular expressions are used to determine whether there are numbers in the actual power dispatching business standard text and the operation specification formula of the business corresponding to the power dispatching business operation specification formula. If there are no numbers in the actual power dispatching business standard text and the operation specification formula of the business corresponding to the power dispatching business operation specification formula, the cosine similarity is used to calculate the similarity between the actual power dispatching business standard text and the operation specification formula of the business corresponding to the power dispatching business operation specification formula. If the similarity calculation result is 1, the actual power dispatching business operation steps are determined to be compliant, otherwise they are determined to be non-compliant; if there are numbers in the actual power dispatching business standard text and the operation specification formula of the business corresponding to the power dispatching business operation specification formula, the cosine similarity is used to compare the Chinese text in the actual power dispatching business standard text with the operation specification formula of the business corresponding to the power dispatching business operation specification formula. The Chinese text in the formula is similarly calculated. If the similarity calculation result is 1, the number in the actual power dispatching business standard text is compared with the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set. If the number in the actual power dispatching business standard text ≤ the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, the actual power dispatching business operation step is determined to be compliant. If the similarity calculation result is not 1 or the number in the actual power dispatching business standard text > the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, it is determined to be non-compliant; if one of the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set has a number, and the other does not have a number, the actual power dispatching business operation step is determined to be non-compliant;

[0014] The steps of calculating cosine similarity are as follows: convert the actual power dispatching business standard text and the corresponding business operation specification in the power dispatching business operation specification set into a vector, where each dimension of the vector represents a word; and then use the cosine similarity formula for calculation, as shown below:

[0015] Cosine Similarity=A·B / ||A||||B||

[0016] Among them, Cosine Similarity is the result of cosine similarity calculation, A·B is the dot product of the actual power dispatching business standard text vector A and the operation specification vector B of the corresponding business in the power dispatching business operation specification set, ||A|| and ||B|| are the Euclidean norms of the actual power dispatching business standard text vector A and the operation specification vector B of the corresponding business in the power dispatching business operation specification set, respectively.

[0017] Furthermore, when calculating the cosine similarity, the cosine similarity of the standard step n in the actual electric power dispatching business standard text and the standard step n in the operation specification formula of the corresponding business in the electric power dispatching business operation specification set is calculated respectively in accordance with the step order, and the final result is expressed as [1 or 0, 1 or 0,…, 1 or 0], where 1 indicates that the standard step n in the actual electric power dispatching business standard text is compliant, and 0 indicates that the standard step n in the actual electric power dispatching business standard text is not compliant. If there is at least one standard step n in the actual electric power dispatching business standard text that is not compliant, then the actual electric power dispatching business operation step is determined to be non-compliant.

[0018] A method for evaluating the standardization of power grid dispatching business operations, comprising the following steps:

[0019] A service name keyword set is constructed according to the names of all electric power dispatching services, and all service name keywords in the service name keyword set are retrieved in the electric power dispatching service normative document, and the context of each retrieved service name keyword is used as the standard operation steps of the corresponding service under the corresponding service name keyword, and the electric power dispatching service operation standard formula set is obtained according to the service name corresponding to each service name keyword and the standard operation steps of the corresponding service;

[0020] The actual operation steps of the electric power dispatching business are calculated for similarity with the operation specifications of the corresponding business in the electric power dispatching business operation specification set, and whether the actual operation steps of the electric power dispatching business are compliant is determined based on the similarity calculation score.

[0021] A computer-readable medium having a computer program / instruction stored thereon, wherein the computer program / instruction executes the above-mentioned method for evaluating the operational standardization of power grid dispatching business when running.

[0022] An electronic device, characterized in that it includes: a memory and a processor, the memory and the processor are communicatively connected to each other, the memory stores computer programs / instructions, and the processor executes the above-mentioned power grid dispatching business operation standardization evaluation method by executing the computer programs / instructions.

[0023] A computer program product includes a computer program / instruction, which implements the above-mentioned method for evaluating the operational standardization of power grid dispatching business when executed by a processor.

[0024] The beneficial effects of the present invention are:

[0025] 1. By constructing a keyword set of power dispatching business names and extracting the standardized operating steps of the corresponding business, a set of power dispatching business operation specifications is formed, which provides a clear and unified operating standard for practice. By calculating the similarity between the actual power dispatching business operation steps and the specification, it is possible to objectively evaluate whether the actual operation is compliant, thereby promptly discovering and correcting non-compliant operations.

[0026] 2. Standardize the actual operation steps of the power dispatching business, so that each step can be calculated separately when calculating the similarity with the standard formula, and the results obtained are more accurate, ensuring the comparability of the actual operation steps of the power dispatching business. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a system block diagram of the present invention.

[0028] Figure 2 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Example 1

[0031] refer to Figure 1 , a power grid dispatching business operation standardization evaluation system, comprising:

[0032] The power dispatching business operation specification extraction module builds a business name keyword set according to the names of all power dispatching businesses, retrieves all business name keywords in the business name keyword set in the power dispatching business specification document, and uses the context of each retrieved business name keyword as the standard operation steps of the corresponding business under the corresponding business name keyword, and obtains the power dispatching business operation specification set according to the business name corresponding to each business name keyword and the standard operation steps of the corresponding business;

[0033] The electric power dispatching business operation evaluation module calculates the similarity between the dispatcher's electric power dispatching business operation steps and the operation specifications of the corresponding business in the electric power dispatching business operation specification set, and determines whether the dispatcher's electric power dispatching business operation steps are compliant based on the similarity calculation score.

[0034] (1) The names of all power dispatching services come from the power system database.

[0035] (2) In the power dispatching business operation specification extraction module, the specific method of retrieving the context of each business name keyword in the power dispatching business specification document as the standard operation steps of the business corresponding to each business name keyword is:

[0036] The power dispatching business normative document is segmented into Chinese words (the Chinese word segmentation uses the jieba word segmentation tool), and each business name keyword is constructed into a regular expression. The regular expression is used to retrieve the context of each business name keyword in the power dispatching business normative document after Chinese word segmentation, and the context is used as the standard operation steps of the business corresponding to each business name keyword. The scope of the context is between two periods. Finally, the retrieved context is manually checked and adjusted.

[0037] The normative documents for power dispatching business can come from written regulations or from texts written based on the dispatcher's experience.

[0038] By performing Chinese word segmentation on the normative documents of power dispatching business, the document content can be processed and parsed more effectively, laying the foundation for subsequent keyword retrieval. By building regular expressions to match the keywords of each business name, the relevant business names in the document can be quickly located, improving retrieval efficiency. The above method realizes the automation of document word segmentation, keyword retrieval and context extraction, reducing manual intervention and improving work efficiency.

[0039] (3) In the power dispatching business operation specification extraction module, the specific method of obtaining the power dispatching business operation specification set according to the business name corresponding to each business name keyword and the standard operation steps of the corresponding business is:

[0040] The standard operation steps are decomposed into the standard operation step formula consisting of Chinese text and numbers in the form of step 1, step 2, ..., step n, and the business name and the standard operation step formula of the corresponding business are organized into the power dispatching business operation standard formula set in the following form: [business name | standard step 1, standard step 2, ..., standard step n], as shown in Table 1:

[0041] Table 1

[0042]

[0043] Decomposing the standard operation steps into standard forms and decomposing long texts into short texts will facilitate subsequent comparison and similarity calculation with the dispatcher's actual operations, thereby improving the accuracy of similarity calculation.

[0044] (4) In the electric power dispatching business operation evaluation module, before calculating the similarity between the dispatcher's electric power dispatching business operation steps and the operation specification formula of the corresponding business in the electric power dispatching business operation specification formula set, the dispatcher's electric power dispatching business operation steps are first converted into an electric power dispatching business standard text that is the same as the Chinese text of the standard step n in the operation step specification formula, expressed as follows: [Business name|Standard step 1, Standard step 2, ..., Standard step n], where the numbers in the standard step n are the numbers involved in the dispatcher's electric power dispatching business operation steps.

[0045] There can be various combinations between standard steps n. Only the correct combination can complete the power dispatching business. For the dispatcher, it is necessary to upload the standard steps n to the standard evaluation system of the power grid dispatching business operation in the order of operation, as shown in Table 2:

[0046]

[0047] The dispatcher's power dispatching business operations can be expressed by different Chinese texts, which makes it inconvenient to compare with the standard operating steps. The Chinese text of the dispatcher's power dispatching business operations is standardized. For example, the dispatcher can only choose the standard step n in this system instead of inputting it independently. Only numbers can be input independently.

[0048] Standardizing the Chinese text of the dispatcher's power dispatching business operations enables the dispatcher's power dispatching business operations to be compared with the operation specifications through an algorithm, ensuring comparability. Further decomposing the standardized operation steps in order to align them with the specification, and more accurately comparing the two

[0049] (5) In the power dispatching business operation evaluation module, the power dispatching business operation steps of the dispatcher are similarly calculated with the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, and the specific steps of determining whether the power dispatching business operation steps of the dispatcher are compliant according to the similarity calculation score are as follows:

[0050] Regular expressions are used to determine whether there are numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business. If there are no numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business, the cosine similarity is used to calculate the similarity between the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business. If the similarity calculation result is 1, it is determined that the dispatcher's power dispatching business operation steps are compliant, otherwise it is determined to be non-compliant; if there are numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business, the cosine similarity is used to compare the Chinese text in the dispatcher's power dispatching business standard text with the operation specification formula of the power dispatching business operation specification formula corresponding to the business. The Chinese text in the formula is similarly calculated. If the similarity calculation result is 1, the number in the dispatcher's power dispatching business standard text is compared with the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set. If the number in the dispatcher's power dispatching business standard text is ≤ the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, the dispatcher's power dispatching business operation steps are determined to be compliant. If the similarity calculation result is not 1 or the number in the dispatcher's power dispatching business standard text is > the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, it is determined to be non-compliant. If one of the dispatcher's power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set has a number, and the other does not have a number, the dispatcher's power dispatching business operation steps are determined to be non-compliant.

[0051] The steps of calculating cosine similarity are as follows: convert the dispatcher's power dispatching business standard text and the power dispatching business operation specification set corresponding to the business operation specification into a vector, where each dimension of the vector represents a word; and then use the cosine similarity formula for calculation, which is as follows:

[0052] Cosine Similarity=A·B / ||A||||B||

[0053] Among them, Cosine Similarity is the result of cosine similarity calculation, A·B is the dot product of the dispatcher's power dispatching business standard text vector A and the corresponding business operation specification vector B in the power dispatching business operation specification set, ||A|| and ||B|| are the Euclidean norms of the dispatcher's power dispatching business standard text vector A and the corresponding business operation specification vector B in the power dispatching business operation specification set, respectively.

[0054] When calculating the cosine similarity, the cosine similarity is calculated for the standard step n in the dispatcher's power dispatching business standard text and the standard step n in the operation specification of the corresponding business in the power dispatching business operation specification set according to the step order. The final result is expressed as [1 or 0, 1 or 0, ..., 1 or 0], where 1 indicates that the standard step n in the dispatcher's power dispatching business standard text is compliant, and 0 indicates that the standard step n in the dispatcher's power dispatching business standard text is not compliant. If there is at least one standard step n in the dispatcher's power dispatching business standard text that is not compliant, then the dispatcher's power dispatching business operation step is determined to be non-compliant, as shown in Table 3:

[0055]

[0056]

[0057] Specifically, the cosine similarity of standard step n and standard step n is calculated one by one. Only on the basis of the previously processed operation specification and standard steps can the cosine similarity be compared. The cosine similarity is used to judge whether the dispatcher's operation is compliant with the regulations, with high accuracy, and realizes the automated management of the dispatcher's business operations, and promptly reminds the dispatcher whether the operation is compliant, without waiting for the problem to occur to find out that the previous operation has caused a problem, thus reducing the property loss and even safety risks caused by this.

[0058] Even based on this technical solution, the performance of the dispatchers is displayed, the accuracy of dispatching tasks performed by different teams / dispatchers in a day is analyzed, and the accuracy ranking of teams / dispatchers is displayed, providing data support for dispatching assessment and safe and stable operation of the power system. Figure 2 shown.

[0059] Example 2

[0060] A method for evaluating the standardization of power grid dispatching business operations, comprising:

[0061] A service name keyword set is constructed according to the names of all electric power dispatching services, and all service name keywords in the service name keyword set are retrieved in the electric power dispatching service normative document, and the context of each retrieved service name keyword is used as the standard operation steps of the corresponding service under the corresponding service name keyword, and the electric power dispatching service operation standard formula set is obtained according to the service name corresponding to each service name keyword and the standard operation steps of the corresponding service;

[0062] The similarity between the dispatcher's power dispatching business operation steps and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set is calculated, and whether the dispatcher's power dispatching business operation steps are compliant is determined based on the similarity calculation score.

[0063] (1) The names of all power dispatching services come from the power system database.

[0064] (2) In the power dispatching business operation specification extraction module, the specific method of retrieving the context of each business name keyword in the power dispatching business specification document as the standard operation steps of the business corresponding to each business name keyword is:

[0065] The power dispatching business normative document is segmented into Chinese words (the Chinese word segmentation uses the jieba word segmentation tool), and each business name keyword is constructed into a regular expression. The regular expression is used to retrieve the context of each business name keyword in the power dispatching business normative document after Chinese word segmentation, and the context is used as the standard operation steps of the business corresponding to each business name keyword. The scope of the context is between two periods. Finally, the retrieved context is manually checked and adjusted.

[0066] The normative documents for power dispatching business can come from written regulations or from texts written based on the dispatcher's experience.

[0067] By performing Chinese word segmentation on the normative documents of power dispatching business, the document content can be processed and parsed more effectively, laying the foundation for subsequent keyword retrieval. By building regular expressions to match the keywords of each business name, the relevant business names in the document can be quickly located, improving retrieval efficiency. The above method realizes the automation of document word segmentation, keyword retrieval and context extraction, reducing manual intervention and improving work efficiency.

[0068] (3) The specific method of obtaining the power dispatching business operation standard set according to the business name corresponding to each business name keyword and the standard operation steps of the corresponding business is:

[0069] The standard operation steps are decomposed into the standard operation step formula consisting of Chinese text and numbers in the form of step 1, step 2, ..., step n, and the business name and the standard operation step formula of the corresponding business are organized into the power dispatching business operation standard formula set in the following form: [business name | standard step 1, standard step 2, ..., standard step n], as shown in Table 1:

[0070] Table 1

[0071]

[0072] Decomposing the standard operation steps into standard forms and decomposing long texts into short texts will facilitate subsequent comparison and similarity calculation with the dispatcher's actual operations, thereby improving the accuracy of similarity calculation.

[0073] (4) Before calculating the similarity between the dispatcher's power dispatching business operation steps and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, the dispatcher's power dispatching business operation steps are first converted into a power dispatching business standard text that is the same as the Chinese text of the standard step n in the operation step specification formula, expressed as follows: [Business name|Standard step 1, Standard step 2, ..., Standard step n], where the numbers in the standard step n are the numbers involved in the dispatcher's power dispatching business operation steps.

[0074] There can be various combinations between standard steps n. Only the correct combination can complete the power dispatching business. For the dispatcher, it is necessary to upload the standard steps n to the standard evaluation system of the power grid dispatching business operation in the order of operation, as shown in Table 2:

[0075]

[0076] The dispatcher's power dispatching business operations can be expressed by different Chinese texts, which makes it inconvenient to compare with the standard operating steps. The Chinese text of the dispatcher's power dispatching business operations is standardized. For example, the dispatcher can only choose the standard step n in this system instead of inputting it independently. Only numbers can be input independently.

[0077] Standardizing the Chinese text of the dispatcher's power dispatching business operations makes it possible to compare the dispatcher's power dispatching business operations with the operating specifications through an algorithm, ensuring comparability.

[0078] (5) The dispatcher's power dispatching business operation steps are similarly calculated with the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, and the specific steps for determining whether the dispatcher's power dispatching business operation steps are compliant based on the similarity calculation score are as follows:

[0079] Regular expressions are used to determine whether there are numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business. If there are no numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business, the cosine similarity is used to calculate the similarity between the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business. If the similarity calculation result is 1, it is determined that the dispatcher's power dispatching business operation steps are compliant, otherwise it is determined to be non-compliant; if there are numbers in the dispatcher's power dispatching business standard text and the operation specification formula of the power dispatching business operation specification formula corresponding to the business, the cosine similarity is used to compare the Chinese text in the dispatcher's power dispatching business standard text with the operation specification formula of the power dispatching business operation specification formula corresponding to the business. The Chinese text in the formula is similarly calculated. If the similarity calculation result is 1, the number in the dispatcher's power dispatching business standard text is compared with the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set. If the number in the dispatcher's power dispatching business standard text is ≤ the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, the dispatcher's power dispatching business operation steps are determined to be compliant. If the similarity calculation result is not 1 or the number in the dispatcher's power dispatching business standard text is > the number in the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, it is determined to be non-compliant. If one of the dispatcher's power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set has a number, and the other does not have a number, the dispatcher's power dispatching business operation steps are determined to be non-compliant.

[0080] The steps of calculating cosine similarity are as follows: convert the dispatcher's power dispatching business standard text and the power dispatching business operation specification set corresponding to the business operation specification into a vector, where each dimension of the vector represents a word; and then use the cosine similarity formula for calculation, which is as follows:

[0081] Cosine Similarity=A·B / ||A||||B||

[0082] Among them, Cosine Similarity is the result of cosine similarity calculation, A·B is the dot product of the dispatcher's power dispatching business standard text vector A and the corresponding business operation specification vector B in the power dispatching business operation specification set, ||A|| and ||B|| are the Euclidean norms of the dispatcher's power dispatching business standard text vector A and the corresponding business operation specification vector B in the power dispatching business operation specification set, respectively.

[0083] When calculating the cosine similarity, the cosine similarity is calculated for the standard step n in the dispatcher's power dispatching business standard text and the standard step n in the operation specification of the corresponding business in the power dispatching business operation specification set according to the step order. The final result is expressed as [1 or 0, 1 or 0, ..., 1 or 0], where 1 indicates that the standard step n in the dispatcher's power dispatching business standard text is compliant, and 0 indicates that the standard step n in the dispatcher's power dispatching business standard text is not compliant. If there is at least one standard step n in the dispatcher's power dispatching business standard text that is not compliant, then the dispatcher's power dispatching business operation step is determined to be non-compliant, as shown in Table 3:

[0084]

[0085]

[0086] Specifically, the cosine similarity of standard step n and standard step n is calculated one by one. Only on the basis of the previously processed operation specification and standard steps can the cosine similarity be compared. The cosine similarity is used to judge whether the dispatcher's operation is compliant with the regulations, with high accuracy, and realizes the automated management of the dispatcher's business operations, and promptly reminds the dispatcher whether the operation is compliant, without waiting for the problem to occur to find out that the previous operation has caused a problem, thus reducing the property loss and even safety risks caused by this.

[0087] Even based on this technical solution, the performance of the dispatchers is displayed, the accuracy of dispatching tasks performed by different teams / dispatchers in a day is analyzed, and the accuracy ranking of teams / dispatchers is displayed, providing data support for dispatching assessment and safe and stable operation of the power system.

The power grid dispatching business operation standardization evaluation system according to claim 3 is characterized by: In the electric power dispatching business operation evaluation module, before calculating the similarity between the actual electric power dispatching business operation steps and the operation specification formula of the corresponding business in the electric power dispatching business operation specification formula set, the actual electric power dispatching business operation steps are first converted into an electric power dispatching business standard text that is the same as the Chinese text of the standard step n in the operation step specification formula, expressed as follows: [business name|standard step 1, standard step 2, ..., standard step n], where the numbers in the standard step n are the numbers involved in the actual electric power dispatching business operation steps.

5. The power grid dispatching business operation standardization evaluation system according to claim 4 is characterized by: In the power dispatching business operation evaluation module, the actual power dispatching business operation steps are similarly calculated with the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, and the specific steps of determining whether the actual power dispatching business operation steps are compliant according to the similarity calculation score are as follows: Use regular expressions to determine whether there are numbers in the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set. If there are no numbers in the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set, then use cosine similarity to calculate the similarity between the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification formula set. If the similarity calculation result is 1, then the actual power dispatching business operation step is determined to be compliant, otherwise it is determined to be non-compliant; If both the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification set contain numbers, then the cosine similarity is used to calculate the similarity between the Chinese text in the actual power dispatching business standard text and the Chinese text in the operation specification formula of the corresponding business in the power dispatching business operation specification set. If the similarity calculation result is 1, the numbers in the actual power dispatching business standard text are compared with the numbers in the operation specification formula of the corresponding business in the power dispatching business operation specification set. If the number in the actual power dispatching business standard text is ≤ the number in the operation specification formula of the corresponding business in the power dispatching business operation specification set, then the actual power dispatching business operation step is determined to be compliant. If the similarity calculation result is not 1 or the number in the actual power dispatching business standard text is > the number in the operation specification formula of the corresponding business in the power dispatching business operation specification set, then it is determined to be non-compliant. If one of the actual power dispatching business standard text and the operation specification formula of the corresponding business in the power dispatching business operation specification set contains numbers and the other does not contain numbers, then the actual power dispatching business operation step is determined to be non-compliant. The steps of calculating cosine similarity are as follows: convert the actual power dispatching business standard text and the corresponding business operation specification in the power dispatching business operation specification set into a vector, where each dimension of the vector represents a word; and then use the cosine similarity formula for calculation, as shown below: Cosine Similarity=A·B / ||A||||B|| Among them, Cosine Similarity is the result of cosine similarity calculation, A·B is the dot product of the actual power dispatching business standard text vector A and the operation specification vector B of the corresponding business in the power dispatching business operation specification set, ||A|| and ||B|| are the Euclidean norms of the actual power dispatching business standard text vector A and the operation specification vector B of the corresponding business in the power dispatching business operation specification set, respectively.
