DETAILED DESCRIPTION

[0019] In order to make the purpose, technical methods and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

If there is a description of "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent the situation where A exists alone, A and B exist at the same time, and B exists alone. Among them, A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0022] In daily operations, when there is a situation in which it is impossible to restore power supply to users through medium-voltage transfer in planned operations (infrastructure projects, repair projects) and temporary operations (medium and low voltage emergency repairs), it is necessary to consider using low-voltage non-stop power supply operations to meet the requirements of power supply reliability. When there is a need for low-voltage non-stop power supply operations, in the process of formulating traditional low-voltage non-stop power supply operation measures, practitioners rely on multiple system data information and actual on-site surveys, and formulate plans based on personal experience. The decision-making evidence and decision-making plan basis have not been solidified, and they are very dependent on the professional quality and historical experience of the personnel in the position.

[0023] Specifically, the plan formulation process requires verification of GIS, system records, metering automation system loads, etc., and understanding of the situation of the outage area and surrounding areas and road sections, and finally verification and formulation of 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. The inefficient working 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 low-voltage non-stop operation measures required for the day, and improve business quality and efficiency.

[0025] The low-voltage non-stop power operation solution decision-making assistance method provided in the embodiment of the present application can be applied to a terminal, can also be applied to a server, and can also be software running in a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc.; the server can be configured as an independent physical server, or a server cluster or distributed system composed of multiple physical servers, and can also be configured as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN) and big data and artificial intelligence platforms; the software can be an application that implements the low-voltage non-stop power operation solution decision-making assistance method, but is not limited to the above forms.

[0026] Embodiments of the present application can be used in numerous general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor 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 distributed computing environments, in which tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0027] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on the attribute information or attribute information set of an object (such as a user, etc.) and other data related to the characteristics of the object, the permission or consent of the corresponding object will be obtained first, and the collection, use and processing of these data will comply with relevant laws and standards. In addition, when the embodiment of the present application needs to obtain the attribute information of an object, a separate permission or separate consent of the corresponding object will be obtained through a pop-up window or by jumping to a confirmation page. After clearly obtaining the separate permission or separate consent of the corresponding object, the relevant data of the object necessary for the normal operation of the embodiment of the present application will be obtained.

[0028] To facilitate understanding, some technical terms involved in the embodiments of the present application are first explained below.

[0029] (1) Load side substation: During the construction process, the medium voltage power supply in this substation is cut off and the transformer is in a power-off state.

[0030] (2) Power supply side substation: During normal operation, this substation can supply power to the low-voltage equipment in the load side substation through low-voltage communication.

[0031] (3) Low-voltage generator truck power outage point: The parking location of the low-voltage generator truck during the construction process preset by the system.

[0032] (4) Maximum load in the implementation month: The maximum load in the same month of the previous year can be used as the maximum load in the implementation month.

[0033] See also Figure 1 , Figure 1 A schematic diagram of the steps of the low-voltage non-stop power supply operation solution decision-making auxiliary method provided in the first embodiment of the present application is as follows: Figure 1As shown, the method includes the following steps S110-S160, and each step is described in detail below.

[0034] Step S110: receiving the load side area with low voltage and non-stop power supply operation requirements selected by the user on the client.

[0035] It should be noted that the client can be an application running on a terminal device (it can be an application of a web browser, a desktop application or a mobile application, etc.). The client can send a request message to the server through the network, and can also receive a response message sent by the server through the network. The client also provides a user interface for the user to interact with the system, so that the user can perform application operations in the user interface, such as selecting the load side area for the planned power outage and the month for the planned power outage, etc. The user interface can also be used to display system information, such as prompt information, recommended power side area information, etc.

[0036] During specific implementation, a map of the jurisdiction area can be displayed in the client's user interface. The user selects a load side area with low-voltage non-stop power supply operation requirements in the user interface. The client sends the load side area information selected by the user to the server, so that the server can start the low-voltage non-stop power supply operation plan auxiliary decision-making process based on the load side area selected by the user.

[0037] The above-mentioned terminal devices refer to terminal devices with data computing and processing functions, including but not limited to smart phones (with communication modules installed), PDAs, tablet computers, etc. These terminal devices are installed with operating systems, including but not limited to: Windows operating system, Android operating system, Apple iPhone OS operating system, etc.

[0038] Step S120: searching for all power supply side sections within a preset radius of the load side section.

[0039] It should be noted that the server receives the load side area selected by the user from the client, and then searches for all power side areas within the preset radius of the load side area based on the pre-stored map data. For example, the preset radius is 200 meters, the current load side area is area A, and with area A as the center, there are 6 areas within a radius of 200 meters, which are recorded as areas B, C, D, E, F and G.

[0040] Step S130: For each power supply side substation, determine whether the power supply side substation meets the low-voltage connection load requirements based on the maximum load data of the power supply side substation and the maximum load data of the load side substation. If the power supply side substation meets the low-voltage connection load requirements, the power supply side substation is used as a candidate power supply side substation.

[0041] For example, the maximum load data here can be at least one of the maximum load of the substation last year and the maximum load of the substation in the implementation month. In specific implementation, the type of maximum load can be selected, and then according to the maximum load of the power side substation of the same type and the maximum load of the load side substation, it is judged whether the power side substation meets the low voltage connection load requirements. If the requirements are met, the power side substation is used as a candidate power side substation.

[0042] As a possible implementation method of the present application, the maximum load data of the power supply side substation includes the maximum load of the power supply side substation last year, and the maximum load data of the load side substation includes the maximum load of the load side substation last year. If the sum of the maximum load of the power supply side substation last year and the maximum load of the load side substation last year is less than or equal to the power supply side transformer capacity, that is, if the maximum load of the power supply side substation last year + the maximum load of the load side substation last year ≤ the power supply side transformer capacity * 100%, then it is confirmed that the power supply side substation meets the low-voltage connection load requirements and is used as a candidate power supply side substation.

[0043] As another possible implementation mode 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, if: 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%, then it is confirmed that the power supply side substation meets the low-voltage connection load requirements and is used as a candidate power supply side substation.

[0044] As another possible implementation method of the present application, the maximum load data of the power supply side substation includes the maximum load of the power supply side substation last year and the maximum load of the power supply side substation in the implementation month; the maximum load data of the load side substation includes the maximum load of the load side substation last year and 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 last year and the maximum load of the load side substation last year is less than or equal to the power supply side transformer capacity, and 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, then the power supply side substation is confirmed to meet the low-voltage contact load requirements and is used as a candidate power supply side substation. That is, the candidate power supply side substation needs to meet the following two conditions at the same time: the maximum load of the power supply side substation last year + the maximum load of the load side substation last year ≤ the power supply side transformer capacity * 100%, 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%.

[0045] Step S140: for the candidate power source side section, weight fusion is performed on multiple feature data of the candidate power source side section to obtain a recommendation score of the candidate power source side section.

[0046] Exemplarily, the characteristic data includes at least one of the following: the maximum load of the power supply side substation last year, the maximum load of the power supply side substation in the implementation month, the laying distance and the number of reserved positions for low-voltage switch cabinets in the power supply side substation.

[0047] In specific implementation, weight coefficients corresponding to various characteristic data are predefined, and then all characteristic data are weighted and fused based on the weight coefficients to obtain a recommended score for the candidate power supply side station area.

[0048] Step S150: Select m power supply side sections with the highest recommendation scores from all candidate power supply side sections as target power supply side sections, where m is an integer greater than or equal to 1.

[0049] For example, the current load side substation is substation A. With substation A as the center, there are 6 substations within a radius of 200 meters, which are recorded as substations B, C, D, E, F and G. Among them, substations B, C, D, E and F meet the low-voltage interconnection load requirements. However, the recommended scores corresponding to substations B, C, D, E and F are determined respectively. Assuming that m is 3, the three substations with the highest recommended scores among substations B, C, D, E and F are used as the target power side substations.

[0050] Step S160: sending a power supply side zone list to the client, so as to display the power supply side zone list on the client, wherein the power supply side zone list includes zone information of m target power supply side zones.

[0051] Exemplarily, the area information of the target power supply side area includes at least one of the following: the power supply side area name, the recommended number of cable laying times, the recommended cable cross-sectional area, the laying cable length and the power supply side area location information.

[0052] Among them, the recommended number of cable laying times and the recommended cable cross-sectional area can be determined by the transfer current Is corresponding to the maximum load of the load-side substation in the implementation month. It should be noted that the transfer current Is corresponding to the maximum load of the load-side substation in the implementation month can be calculated by the following two methods.

[0053] The first method is to calculate based on the relationship between load and current: Is (Formula 1) Among them, S represents the maximum load of the load-side station in the implementation month.

[0054] The second method is to match the transformer rated current I according to the transformer rated capacity. A , calculate Is by the load factor Y: Is = I A *Y (Formula 2) Among them, the load rate Y can be determined by the load rate of the load-side station in the implementation month, and the rated capacity of the transformer is the rated capacity of the transformer on the power supply side.

[0055] The corresponding relationship between the rated capacity and rated current of the transformer can be referred to as shown in Table 1 below.

[0056] Table 1

[0057] It should be noted that, in some embodiments, the substation information of the target power supply side substation may also include the power supply side substation transformer capacity, the maximum load of the power supply side substation last year, or the maximum load of the power supply side substation in the implementation month, etc., and this application does not limit this.

[0058] The solution provided by the embodiment of the present application first searches for all power side areas within a preset radius of the load side area according to the load side area with low-voltage non-stop power supply operation requirements selected by the user on the client; then, for the found power side area, determines whether the power side area meets the low-voltage contact load requirements, and uses the power side area that meets the requirements as a candidate power side area, and then scores each candidate power side area, and pushes the m candidate power side areas with the highest scores as target power side areas to the client for display, and displays a power side area list on the client, the power side area list includes the area information of the recommended m target power side areas, thereby providing users with auxiliary decision-making for low-voltage non-stop power supply operation plans, improving the degree of automation in formulating low-voltage non-stop power supply operation plans, and providing support for improving business quality and efficiency.

[0059] See also Figure 2 , is a schematic diagram of the steps of determining the recommended score of the candidate power side station area provided by an embodiment of the present application, such as Figure 2 As shown, multiple feature data of the candidate power supply side area are weighted and fused to obtain the recommended score of the candidate power supply side area, which may include: Step S210: normalize each feature data to obtain a normalized value corresponding to the feature data.

[0060] It should be noted that each feature data is normalized so that different types of feature data are mapped to values ​​between 0 and 1, so as to facilitate weight fusion processing of multiple different types of feature data.

[0061] For the characteristic data "laying distance", suppose there are n candidate power supply side stations that meet the low-voltage connection load requirements, that is, there are n transformers available for low-voltage connection, and the distance of the transformer available for low-voltage connection is The average distance is , the standard deviation is , with the highest score being 100. First, the score is quantified according to z-score standardization to obtain the quantitative value of the distance available for low-voltage interconnection transformers , known According to the actual application scenario, the farther the distance, the lower the score. The quantized value of the distance available to the low-voltage interconnection transformer is mapped on the sigmoid function and geometrically scaled to obtain The specific function derivation is as follows: Formula 3-1 to Formula 3-3: (Formula 3-1); (Formula 3-2); (Formula 3-3).

[0062] For the characteristic data "last year's maximum load", suppose there are n candidate power supply side areas that meet the low-voltage connection load requirements, and record the minimum value of the highest load last year corresponding to the n candidate power supply side areas as Load yeah-min , and Load yeah-min The normalized value is 1, and the highest load of last year corresponding to other candidate power supply side areas is based on Load yeah-min The ratio is scaled geometrically and mapped to a normalized value of (0, 1). The higher the maximum load last year corresponding to the candidate power supply side area, the lower the normalized value of its maximum load last year.

[0063] For the characteristic data "maximum load of the power supply side area in the implementation month", suppose there are n candidate power supply side areas that meet the low-voltage connection load requirements, and the minimum value of the maximum load of the implementation month corresponding to the n candidate power supply side areas is recorded as Load month-min , and Load month-min Mapped to a normalized value of 1; the highest load of the implementation month corresponding to other candidate power supply side areas is based on Load month-min The ratio is scaled geometrically and mapped to a normalized value of (0, 1). The higher the maximum load of the implementation month corresponding to the candidate power supply side station area, the lower the normalized value of the maximum load of the implementation month.

[0064] For the characteristic data "number of reserved positions for low-voltage switch cabinets in the power supply side area", suppose there are n candidate power supply side areas that meet the requirements of low-voltage interconnection load, and the number of low-voltage switch cabinets with the largest number of reserved positions among the n candidate power supply side areas is recorded as Switch max , and switch max Mapped to a normalized value of 1; the number of low-voltage switch cabinet reserved positions corresponding to other candidate power supply side areas is based on the Switch maxThe ratio is scaled geometrically and mapped to a normalized value of (0, 1). The more reserved positions for low-voltage switchgear in the candidate power supply side area, the higher the normalized value of the reserved positions for low-voltage switchgear.

[0065] It should be noted that, during specific implementation, a corresponding normalization method can be selected according to the characteristics of the data, and the embodiments of the present application do not limit this.

[0066] Step S220: performing weight fusion according to the normalized values ​​and weight values ​​corresponding to all feature data to obtain a recommendation score for the candidate power supply side station area.

[0067] As a possible embodiment of the present application, the characteristic data include the maximum load of the power side substation last year, the maximum load of the power side substation in the implementation month, the laying distance and the number of reserved positions for the low-voltage switch cabinet in the power side substation. The weight of each characteristic data is set to 0.25, and then the normalized value of each characteristic data is multiplied by the weight to obtain the weight score of the characteristic data. The weight scores of all the characteristic data are added together to obtain the recommended score of the candidate power side substation.

[0068] As a possible embodiment of the present application, the characteristic data include the maximum load of the power side substation last year, the maximum load of the power side substation in the implementation month and the laying distance. The weight of each characteristic data is set to 1 / 3, and then the normalized value of each characteristic data is multiplied by the weight to obtain the weight score of the characteristic data. The weight scores of all the characteristic data are added together to obtain the recommended score of the candidate power side substation.

[0069] As a possible embodiment of the present application, after selecting m target power side substations with the highest recommendation scores from all candidate power side substations as target power side substations, it also includes: judging whether there is an obstruction between each target power side substation and the load side substation based on map information, and arranging the substation information of the target power side substation with obstruction to the end of the power side substation list, and arranging the substation information of other target power side substations without obstruction in the power side substation list in descending order of the recommendation score.

[0070] For example, m is 3, and the three target power supply side substations finally determined according to the recommended scores are substations B, C, and D. These three substations are arranged in descending order according to the recommended scores, namely substation D, substation C, and substation B. However, according to the map information, there is a river barrier between substation D and the load side substation, so substation D is arranged at the end of the power supply side substation list. Therefore, the final order of the three substations in the power supply side substation list is substation C, substation B, and substation D.

[0071] It is understandable that the existence of a barrier between the two substations will increase the difficulty of implementing low-voltage communication. Therefore, when a barrier is found between the target power supply side substation and the load side substation, the target power supply side substation will be regarded as the substation with the lowest recommended degree and will be placed at the end of the list.

[0072] In an embodiment of the present application, the information of the recommended target power side areas is displayed to the user in a list form, and each target power side area is arranged from high to low according to the recommendation degree, so that the user can select the power side area that ultimately provides low-voltage power supply to the load side area according to the recommendation degree.

[0073] See also Figure 3 , which is a schematic diagram of the steps of the low-voltage non-stop power supply operation solution decision-making auxiliary method provided in the second embodiment of the present application, such as Figure 3 As shown, the method comprises the following steps: Step S310: receiving a load side area with low voltage and non-stop power supply operation requirements selected by the user on the client; Step S320: searching for all power supply side stations within a preset radius of the load side station; Step S330: If the power side substation is not found within the preset radius of the load side substation or there is no power side substation that meets the low-voltage connection load requirements within the preset radius of the load side substation, a first prompt message is sent to the client for display on the client. The first prompt message is used to prompt the user that there is no low-voltage connection plan that meets the requirements and recommends using a low-voltage generator vehicle access plan instead.

[0074] Step S340: Sending map rendering information to the client, so that the client can display a map of an area within a preset radius that includes the load side station area according to the map rendering information.

[0075] Step S350: receiving the power generation vehicle parking spot selected by the user on the map displayed on the client.

[0076] Step S360: If it is determined that the distance between the generator truck parking point and the load side platform is less than or equal to the generator truck parking distance threshold and there is no obstruction, a low-voltage generator truck access recommendation plan is sent to the client for display on the client.

[0077] It is understandable that if the power supply side area is not found within the preset radius of the load side area, or if there is no power supply side area that meets the low-voltage connection load requirements within the preset radius of the load side area, then a low-voltage generator truck can be selected to provide low-voltage power supply to the load side area. In this embodiment of the application, the first prompt information is displayed on the client to prompt the user that there is currently no low-voltage connection solution that meets the requirements according to the load side area selected by the user, and the user is advised to use the low-voltage generator truck access solution instead.

[0078] It is understandable that in the embodiment of the present application, the server also sends map rendering information to the client, and the client renders a map of a preset radius range area including the load side station area based on the received map rendering information. The user can select a parking point for the low-voltage generator truck on the map displayed by the client, and the parking point for the generator truck selected by the client user on the map displayed by the client is sent to the server, and accordingly, the server receives the parking point for the generator truck selected by the user on the map displayed by the client from the client.

[0079] It can be understood that in the embodiment of the present application, the server generates a recommended solution for low-voltage power generation vehicle access based on the power generation vehicle parking point selected by the user.

[0080] Specifically, the recommended plan for low-voltage generator vehicle access includes at least one of the following information: generator vehicle configuration capacity, recommended number of cable laying times, recommended cable cross-sectional area, laying cable length and generator vehicle parking point location information.

[0081] Among them, the configuration capacity of the power generation vehicle can be determined according to the maximum load data of the load side area, such as selecting a capacity higher than the maximum load of the load side area in the implementation month. The recommended number of cable laying times and the recommended cable cross-sectional area can be determined by the transfer current Is corresponding to the maximum load of the load side area in the implementation month. For details, please refer to the previous description. The length of the cable laying can be determined by the distance from the power generation vehicle parking point to the load side area. The power generation vehicle parking point positioning information is the power generation vehicle parking point location information selected by the user.

[0082] See also Figure 4 , which is a schematic diagram of the steps of the low-voltage non-stop power supply operation solution decision-making auxiliary method provided in the third embodiment of the present application, such as Figure 4 As shown, after step S350, the following further includes: Step S370: If it is determined that the distance between the generator truck parking point and the load side platform is greater than the preset generator truck parking distance threshold, a second prompt message is sent to the client for display on the client. The second prompt message is used to prompt the user that the distance of the generator truck parking point selected is too far and prompt the user to reselect the generator truck parking point.

[0083] For example, the preset parking distance threshold for the generator truck is 250 meters. If the distance between the generator truck parking point selected by the user and the load side platform area is greater than 250 meters, the second prompt information will be displayed on the client to remind the user that the distance to the generator truck parking point selected by the user is too far and prompt the user to reselect the generator truck parking point.

[0084] See also Figure 5 , which is a schematic diagram of the steps of the low-voltage non-stop power supply operation solution decision-making auxiliary method provided in the fourth embodiment of the present application, such as Figure 5 As shown, after step S350, the following further includes: Step S380: If it is determined that there is an obstruction between the parking point of the generator truck and the load side area, a third prompt message is sent to the client for display on the client. The third prompt message is used to remind the user that there is an obstruction between the parking point of the generator truck and the load side area and to prompt the user to reselect the parking point of the generator truck.

[0085] For example, if there is a large building blocking the parking spot of the generator truck selected by the user and the load side area, the third prompt information is displayed on the client to remind the user that there is a barrier between the parking spot of the generator truck and the load side area and to prompt the user to reselect the parking spot of the generator truck.

If the power supply side area meets the low-voltage connection load requirements, the power supply side area is used as a candidate power supply side area; The second processing module is used to perform weight fusion on multiple feature data of the candidate power supply side station area to obtain a recommendation score for the candidate power supply side station area; A third processing module is used to select m candidate power supply side sections with the highest recommendation scores as target power supply side sections from all candidate power supply side sections, where m is an integer greater than or equal to 1; The sending module is used to send a power supply side area list to the client, so that the power supply side area list is displayed on the client, and the power supply side area list includes area information of m target power supply side areas.
