[0054] In daily work, when there are cases that cannot be restored to users by medium voltage transfer in planned work (capital projects, repair projects) and temporary work (low-voltage repair), low-voltage uninterrupted work needs to be considered to meet the requirements of power supply reliability. When there is a demand for low-voltage uninterrupted work, in the traditional process of formulating low-voltage uninterrupted work measures, employees rely on multiple system data information and actual site investigation to make plans based on personal experience. The decision-making credentials and decision-making plans are not solidified, and are very dependent on the professional quality and historical experience of the staff in the post.

[0055] Specifically, the plan development process needs to verify the load conditions of GIS, system account, and metering automation system, find out the situation of the outage area and the surrounding area and the road section, and finally verify and develop the plan on site. A large amount of data and on-site preparation work needs to be completed manually. The search, cleaning, analysis and mining of low-voltage data rely on traditional office software tools, and the inefficient work mode is very time-consuming and labor-intensive. It is urgent to use digital means to get rid of repetitive and low-value work, quickly generate the required low-voltage uninterrupted work measures for the day, and improve business quality and efficiency.

[0056] Based on the above problems, the embodiment of the present application provides a low-voltage uninterrupted operation scheme auxiliary decision method, a low-voltage uninterrupted operation scheme auxiliary decision system, a computer device and a computer readable storage medium, which aims to quickly generate the required low-voltage uninterrupted operation measures on the same day and improve the business quality and efficiency.

In some embodiments, the terminal can be a smart phone, a tablet computer, a notebook computer, a desktop computer, etc.; the server can be configured as a stand-alone physical server, can also be configured as a server cluster or a distributed system formed by multiple physical servers, and can also be configured as a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content delivery network (CDN), and big data and artificial intelligence platform; and the software can be an application that implements the low-voltage uninterrupted operation scheme auxiliary decision method, but is not limited to the above forms.

[0058] The embodiments of the present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld devices or portable devices, tablet devices, multi-processor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in a distributed computing environment, in which tasks are performed by remote processing devices connected by a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media, including storage devices.

[0059] It should be noted that in various specific embodiments of the present application, when relevant processing needs to be performed according to attribute information or attribute information set of an object (such as a user, etc.) and other data related to the characteristics of the object, permission or consent of the corresponding object is obtained first, and the collection, use and processing of the data are in compliance with relevant laws and standards. In addition, when the embodiments of the present application need to obtain attribute information of an object, separate permission or separate consent of the corresponding object is obtained through a pop-up window or by jumping to a confirmation page, and after obtaining the separate permission or separate consent of the corresponding object, the necessary related data of the object for enabling the embodiments of the present application to normally operate is obtained.

[0060] For ease of understanding, some technical terms related to the embodiments of the present application are first explained below.

[0061] (1) Load side area: In the construction process, the medium voltage power supply of the area is powered off, and the transformer is in a powered-off state.

[0062] (2) Power supply side area: In normal operation, the area can supply power to the low-voltage equipment of the load side area through low-voltage contact.

[0063] (3) Low-voltage power generation vehicle power-off point: The parking position of the low-voltage power generation vehicle in the system preset construction process.

[0064] (4) Highest load of the implementation month: The highest load of the area in the same month last year can be used as the highest load of the implementation month.

[0065] Reference Figure 1 , Figure 1 The steps of the low-voltage uninterrupted operation scheme assisted decision-making method provided by the first embodiment of the present application are shown in the schematic diagram as Figure 1 The method includes the following steps S110-S160, which will be described in detail below.

[0066] Step S110: Receive the load side area with low-voltage uninterrupted operation demand selected by the user on the client side.

[0067] It should be noted that the client can be an application program (such as a web browser application program, a desktop application program or a mobile application program, etc.) running on a terminal device. The client can send request messages to the server through the network, and can also receive response messages sent by the server through the network. The client also provides a user interface for user interaction with the system, so that the user can perform application operations on the user interface, such as selecting the load side area to be powered off and the month to implement the power-off plan, etc. The user interface can also be used to display information of the system, such as prompt information, recommended power supply side area information, etc.

[0068] In implementation, a map of the jurisdiction can be displayed in the user interface of the client, the user selects a load side substation with low voltage uninterrupted operation requirement in the user interface, and the client sends the information of the load side substation selected by the user to the server, so that the server starts the low voltage uninterrupted operation scheme auxiliary decision-making process based on the load side substation selected by the user.

[0069] The terminal device mentioned above refers to a terminal device with data calculation processing function, including but not limited to smart phones, palm computers, tablet computers and the like (installed with communication modules). These terminal devices are all installed with operating systems, including but not limited to Windows operating system, Android operating system and Apple iPhone OS operating system and the like.

[0070] Step S120: find all power supply side substations within the preset radius range of the load side substation.

[0071] It should be noted that the server receives the load side substation selected by the user from the client, and then finds all power supply side substations within the preset radius range of the load side substation based on the pre-stored map data. For example, the preset radius range is 200 meters, and the current load side substation is substation A. Within the radius of 200 meters with substation A as the center, there are 6 substations, which are respectively recorded as substations B, C, D, E, F and G.

[0072] Step S130: for each power supply side substation, according to the maximum load data of the power supply side substation and the maximum load data of the load side substation, it is judged whether the power supply side substation meets the low voltage contact load requirement, and if the power supply side substation meets the low voltage contact load requirement, the power supply side substation is taken as a candidate power supply side substation.

[0073] For example, the maximum load data here can be at least one of the maximum load of the substation in the last year and the maximum load of the substation in the implementation month. In implementation, the type of maximum load can be selected, and then according to the maximum load of the power supply side substation of the same type and the maximum load of the load side substation, it is judged whether the power supply side substation meets the low voltage contact load requirement, and if the requirement is met, the power supply side substation is taken as a candidate power supply side substation.

[0074] As a possible implementation manner of the present application, the maximum load data of the power supply side substation includes the maximum load of the power supply side substation in the last year, and the maximum load data of the load side substation includes the maximum load of the load side substation in the last year. If the sum of the maximum load of the power supply side substation in the last year and the maximum load of the load side substation in the last year is less than or equal to the capacity of the power supply side transformer, i.e. the maximum load of the power supply side substation in the last year + the maximum load of the load side substation in the last year ≤ the capacity of the power supply side transformer * 100%, it is confirmed that the power supply side substation meets the low voltage contact load requirement, and it is taken as a candidate power supply side substation.

[0075] As another possible implementation of the present application, the maximum load data of the power supply side substation includes the maximum load of the power supply side substation in the implementation month, and the maximum load data of the load side substation includes the maximum load of the load side substation in the implementation month. If the sum of the maximum load of the power supply side substation in the implementation month and the maximum load of the load side substation in the implementation month is less than or equal to the power supply side transformer capacity, that is, the maximum load of the power supply side substation in the implementation month + the maximum load of the load side substation in the implementation month ≤ the power supply side transformer capacity * 100%, it is confirmed that the power supply side substation meets the low-voltage tie-in load requirement, and it is taken as a candidate power supply side substation.

[0076] As another possible implementation of the present application, the maximum load data of the power supply side substation includes the maximum load of the power supply side substation in the implementation month, and the maximum load data of the load side substation includes the maximum load of the load side substation in the implementation month. If the sum of the maximum load of the power supply side substation in the implementation month and the maximum load of the load side substation in the implementation month is less than or equal to the power supply side transformer capacity, that is, the maximum load of the power supply side substation in the implementation month + the maximum load of the load side substation in the implementation month ≤ the power supply side transformer capacity * 100%, it is confirmed that the power supply side substation meets the low-voltage tie-in load requirement, and it is taken as a candidate power supply side substation.

[0077] Step S140: For the candidate power supply side substation, the weight fusion is performed on the multiple feature data of the candidate power supply side substation to obtain a recommended score of the candidate power supply side substation.

[0078] For example, the feature data includes at least one of the maximum load of the power supply side substation in the previous year, the maximum load of the power supply side substation in the implementation month, the laying distance, and the number of reserved positions of the low-voltage switch cabinet of the power supply side substation.

[0079] In a specific implementation, the weight coefficients corresponding to various feature data are defined in advance, and then the weight fusion is performed on all the feature data based on the weight coefficients to obtain the recommended score of the candidate power supply side substation.

[0080] Step S150: From all the candidate power supply side substations, the m target power supply side substations with the highest recommended scores are selected, and m is an integer greater than or equal to 1.

[0081] For example, the current load side block is block A, and block A is taken as the center, and there are 6 blocks within a radius of 200 meters, which are respectively recorded as blocks B, C, D, E, F and G. Among them, blocks B, C, D, E and F meet the low-voltage contact load requirements, and the recommended scores of blocks B, C, D, E and F are determined respectively. Assuming that m is 3, the three blocks with the highest recommended scores among blocks B, C, D, E and F are taken as the target power supply side blocks.

[0082] Step S160: sending the power supply side block list to the client for displaying the power supply side block list on the client, and the power supply side block list includes the block information of the m target power supply side blocks.

[0083] For example, the block information of the target power supply side block includes at least one of the following: power supply side block name, recommended cable laying number, recommended cable cross-sectional area, cable laying length and power supply side block positioning information.

[0084] Among them, the recommended cable laying number and the recommended cable cross-sectional area can be determined by the transfer current Is corresponding to the highest load of the load side block implementation month. It should be noted that the transfer current Is corresponding to the highest load of the load side block implementation month can be calculated in the following two ways.

[0085] The first way is to calculate according to the relationship between load and current:

[0086] Is (Formula 1)

[0087] Among them, S represents the highest load of the load side block implementation month.

[0088] The second way is to calculate Is by load rate Y according to the transformer rated current I A corresponding to the transformer rated capacity.

[0089] Is = I A *Y (Formula 2)

[0090] Among them, the load rate Y can be determined by the load rate of the load side block implementation month, and the transformer rated capacity is the power supply side transformer rated capacity.

[0091] The corresponding relationship between the transformer rated capacity and the rated current can be referred to as shown in the following table 1.

[0092] Table 1

[0093]

[0094] It should be noted that in some embodiments, the substation information of the target power supply side substation can also include the transformer capacity of the power supply side substation, the highest load of the power supply side substation in the past year, or the highest load of the power supply side substation in the implementation month, etc., which is not limited in the present application.

[0095] The scheme provided by the embodiments of the present application first finds all power supply side substations within a preset radius range of the load side substation selected by the user on the client side which has low-voltage uninterrupted operation demand; then judges whether the power supply side substations meet the low-voltage contact load requirement, and takes the power supply side substations meeting the requirement as candidate power supply side substations, further scores each candidate power supply side substation, and pushes the m candidate power supply side substations with the highest scores as target power supply side substations to the client side for display, displays the power supply side substation list on the client side, and the power supply side substation list includes the substation information of the recommended m target power supply side substations, so as to provide auxiliary decision-making for the user to provide a low-voltage uninterrupted operation scheme and improve the automation degree of the low-voltage uninterrupted operation scheme, thereby providing support for improving business quality and efficiency.

[0096] Referring to Figure 2 , the step schematic diagram for determining the recommended score of the candidate power supply side substation provided by an embodiment of the present application is shown as Figure 2 , the weight fusion of the multiple feature data of the candidate power supply side substation is performed to obtain the recommended score of the candidate power supply side substation, which can include:

[0097] Step S210: Normalizing each feature data to obtain a normalized value corresponding to the feature data.

[0098] It should be noted that the normalization of each feature data maps different types of feature data to values from 0 to 1, so as to facilitate the weight fusion processing of multiple different types of feature data.

[0099] For the feature data "laying distance", assuming that there are n candidate power supply side substations meeting the low-voltage contact load requirement, that is, there are n transformers available for low-voltage contact, assuming that the distance of the transformer available for low-voltage contact is , the average value of the distance is , the standard deviation is , and the highest score is 100 points. First, the score is quantified according to z-score standardization to obtain the quantized value of the distance of the transformer available for low-voltage contact , and is known. According to the actual application scenario, the farther the distance, the lower the score, and the quantized value of the distance of the transformer available for low-voltage contact is mapped on the sigmoid function and is subjected to equi-proportional scaling to obtain . The specific function derivation is as follows formulas 3-1 to 3-3:

[0100] (Formula 3-1);

[0101] (Formula 3-2);

[0102] (Formula 3-3).

[0103] For the feature data "last year's maximum load", suppose that there are n candidate power supply side areas that meet the low-voltage contact load requirement, the minimum value of the last year's maximum load of the n candidate power supply side areas is denoted as Load yeah-min , and Load yeah-min is mapped to the normalized value 1; the last year's maximum load of other candidate power supply side areas is scaled by the ratio with Load yeah-min , and is mapped to the normalized value (0, 1), and the higher the last year's maximum load of the candidate power supply side area, the lower the normalized value of the last year's maximum load.

[0104] For the feature data "maximum load of the implementation month of the power supply side area", suppose that there are n candidate power supply side areas that meet the low-voltage contact load requirement, the minimum value of the maximum load of the implementation month of the n candidate power supply side areas is denoted as Load month-min , and Load month-min is mapped to the normalized value 1; the maximum load of the implementation month of other candidate power supply side areas is scaled by the ratio with Load month-min , and is mapped to the normalized value (0, 1), and the higher the maximum load of the implementation month of the candidate power supply side area, the lower the normalized value of the maximum load of the implementation month.

[0105] For the feature data "number of low-voltage switch cabinet reserved positions of the power supply side area", suppose that there are n candidate power supply side areas that meet the low-voltage contact load requirement, the maximum number of low-voltage switch cabinet reserved positions of the n candidate power supply side areas is denoted as Switch max , and Switch max is mapped to the normalized value 1; the number of low-voltage switch cabinet reserved positions of other candidate power supply side areas is scaled by the ratio with Switch max , and is mapped to the normalized value (0, 1), and the more the number of low-voltage switch cabinet reserved positions of the candidate power supply side area, the higher the normalized value of the number of low-voltage switch cabinet reserved positions.

[0106] It should be noted that in specific implementation, the corresponding normalization method can be selected according to the characteristics of the data, and the embodiments of the present application do not limit this.

[0107] Step S220: weight fusion is performed on the normalized values and weight values corresponding to all feature data to obtain a recommended score of the candidate power side substation.

[0108] As a possible embodiment of the present application, the feature data includes the highest load of the power side substation in the last year, the highest load of the power side substation in the implementation month, the laying distance, and the number of reserved positions of the low-voltage switch cabinet of the power side substation, and the weight of each feature data is 0.25. Then, the normalized value of each feature data is multiplied by the weight to obtain the weight score of the feature data. The weight scores of all feature data are added to obtain the recommended score of the candidate power side substation.

[0109] As a possible embodiment of the present application, the feature data includes the highest load of the power side substation in the last year, the highest load of the power side substation in the implementation month, and the laying distance, and the weight of each feature data is 1 / 3. Then, the normalized value of each feature data is multiplied by the weight to obtain the weight score of the feature data. The weight scores of all feature data are added to obtain the recommended score of the candidate power side substation.

[0110] As a possible embodiment of the present application, after selecting m target power side substations with the highest recommended scores from all candidate power side substations, the method further includes: determining whether there is an obstruction between each target power side substation and the load side substation according to the map information, and arranging the substation information of the target power side substation with the obstruction to the end of the power side substation list, and arranging the substation information of the other target power side substations without the obstruction in the power side substation list in the order of the recommended scores from high to low.

[0111] For example, m is 3, and the three target power side substations finally determined according to the recommended scores are substation B, substation C, and substation D. The three substations are arranged in the order of the recommended scores from high to low, and the order is substation D, substation C, and substation B. However, according to the map information, there is a river obstruction between substation D and the load side substation. Therefore, substation D is arranged to the end of the power side substation list. Thus, the final order of the three substations in the power side substation list is substation C, substation B, and substation D.

[0112] It can be understood that the existence of an obstruction between two substations will increase the difficulty of implementation of low-voltage contact. Therefore, when it is found that there is an obstruction between the target power side substation and the load side substation, the target power side substation is arranged to the end of the list as a substation with the lowest recommended degree.

[0113] In the embodiments of the present application, the information of the recommended target power side substations is displayed to the user in the form of a list, and each target power side substation is arranged in the order of the recommended degree from high to low, so that the user can select the power side substation that finally provides low-voltage power supply for the load side substation according to the recommended degree.

[0114] Referring to Figure 3 The schematic diagram of the steps of the low-voltage uninterrupted operation scheme auxiliary decision method provided for the second embodiment of the application is shown in FIG. 3, and the method comprises the following steps: Figure 3

[0115] Step S310: receiving a load-side substation selected by a user on a client and having a low-voltage uninterrupted operation requirement.

[0116] Step S320: searching for all power source-side substations within a preset radius range of the load-side substation.

[0117] Step S330: if no power source-side substation is found within the preset radius range of the load-side substation or no power source-side substation meeting the low-voltage connection load requirement is found within the preset radius range of the load-side substation, sending first prompt information to the client for displaying the first prompt information on the client, and the first prompt information is used to prompt the user that no low-voltage connection scheme meeting the requirement is available and to suggest using a low-voltage generator car access scheme.

[0118] Step S340: sending map rendering information to the client for displaying a map of a region including the preset radius range of the load-side substation on the client according to the map rendering information.

[0119] Step S350: receiving a generator car parking point selected by the user on the map displayed on the client.

[0120] Step S360: if it is determined that the distance between the generator car parking point and the load-side substation is less than or equal to a generator car parking distance threshold and no barrier exists, sending a low-voltage generator car access recommended scheme to the client for displaying the low-voltage generator car access recommended scheme on the client.

[0121] It can be understood that if no power source-side substation is found within the preset radius range of the load-side substation or no power source-side substation meeting the low-voltage connection load requirement is found within the preset radius range of the load-side substation, a low-voltage generator car can be selected to provide low-voltage power supply for the load-side substation. In the embodiment of the application, the first prompt information is displayed on the client to prompt the user that no low-voltage connection scheme meeting the requirement is available according to the load-side substation selected by the user, and the user is suggested to use the low-voltage generator car access scheme.

[0122] It can be understood that the server also sends map rendering information to the client in the embodiment of the application, and the client renders a map of a region including the preset radius range of the load-side substation based on the received map rendering information. The user can select a generator car parking point on the map displayed on the client, and the generator car parking point selected by the user on the map displayed on the client is sent to the server, and accordingly, the server receives the generator car parking point selected by the user on the map displayed on the client from the client. ​

[0123] It can be understood that, in the embodiments of the present application, the server generates a low-voltage power car access recommendation scheme according to the user-selected power car parking point.

[0124] Specifically, the low-voltage power car access recommendation scheme includes at least one of the following information: power car configuration capacity, recommended cable laying times, recommended cable cross-sectional area, cable laying length, and power car parking point positioning information.

[0125] Among them, the power car configuration capacity can be determined according to the highest load data of the load side block area, such as selecting a capacity higher than the highest load of the load side block area in the implementation month. The recommended cable laying times and the recommended cable cross-sectional area can be determined by the transfer current Is corresponding to the highest load of the load side block area in the implementation month. Specifically, reference can be made to the previous description. The cable laying length can be determined by the distance from the power car parking point to the load side block area. The power car parking point positioning information is the user-selected power car parking point position information.

[0126] Referring to Figure 4 The step schematic diagram of the low-voltage uninterrupted operation scheme auxiliary decision-making method provided by the third embodiment of the present application is shown in Figure 4 As shown in the figure, after step S350, it further includes:

[0127] Step S370: If it is determined that the distance between the power car parking point and the load side block area is greater than the preset power car parking distance threshold, a second prompt information is sent to the client for displaying the second prompt information on the client. The second prompt information is used to prompt the user that the distance of the selected power car parking point is too far and to prompt the user to reselect the power car parking point.

[0128] For example, the preset power car parking distance threshold is 250 meters. If the distance between the user-selected power car parking point and the load side block area is greater than 250 meters, the second prompt information is displayed on the client to prompt the user that the distance of the selected power car parking point is too far and to prompt the user to reselect the power car parking point.

[0129] Referring to Figure 5 The step schematic diagram of the low-voltage uninterrupted operation scheme auxiliary decision-making method provided by the fourth embodiment of the present application is shown in Figure 5 As shown in the figure, after step S350, it further includes:

[0130] Step S380: If it is determined that there is an obstruction between the power car parking point and the load side block area, a third prompt information is sent to the client for displaying the third prompt information on the client. The third prompt information is used to prompt the user that there is an obstruction between the power car parking point and the load side block area and to prompt the user to reselect the power car parking point.

[0131] For example, if there is a large building between the user-selected power generation vehicle parking point and the load-side transformer area, the third prompt information is displayed on the client to prompt the user that there is an obstruction between the power generation vehicle parking point and the load-side transformer area and to prompt the user to reselect the power generation vehicle parking point.
