[0052] With the acceleration of new urbanization, urban renewal, improvement of residents' electricity quality and rural modernization, the requirements for urban power supply reliability are constantly increasing, and the economic losses and impacts caused by power outages are becoming increasingly greater. It is necessary to consider using low-voltage non-stop operations to meet the requirements of power supply reliability.

[0053] In the related technologies, the formulation of low-voltage non-stop power supply operation plans relies on the manual formulation of construction personnel based on their personal work experience and previous data. 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 construction personnel. There is a lack of low-voltage non-stop power supply operation methods driven by data support, which makes the low-voltage non-stop power supply operation methods low in reliability; or, the construction personnel go to the actual site for investigation, and then formulate low-voltage non-stop power supply operation methods according to the actual voltage conditions, which consumes labor costs and has low efficiency. At present, low-voltage non-stop power supply operations also use low-voltage power generation vehicles in the substation area for power supply transfer. Conventional low-voltage non-stop power supply operation plans in the substation area lack unified data collection.

[0055] Please refer to the accompanying drawings below for further explanation of the low-voltage non-stop operation method, controller and readable storage medium provided in the embodiments of the present application.

[0056] Reference Figure 1 As shown, Figure 1 1 is a flow chart of a low-voltage non-stop power operation method provided in an embodiment of the present application. The low-voltage non-stop power operation method includes but is not limited to steps S100 to S700. Specifically,

[0058] Step S200: when there is a low-voltage non-stop power operation request, determining the power outage area corresponding to the low-voltage non-stop power operation request;

[0059] Step S300: Determine whether the outage area meets the load requirements of the low-voltage contact area;

[0060] Step S400: When the outage area meets the load requirements of the low-voltage contact area, the contact distance of the outage area is calculated and the cable laying is determined, and a first low-voltage non-stop power supply operation plan is generated according to the contact distance and the cable laying;

[0061] Step S500: using a feature scaling evaluation algorithm to score the first low-voltage non-stop operation plan to obtain a recommended score;

[0062] Step S600: when the recommended score is greater than a preset score threshold, the first low-voltage non-stop operation plan is uploaded to the management platform and stored in the history database;

[0063] Step S700: In response to a first execution signal of the low-voltage non-stop power operation, an optimal first low-voltage non-stop power operation plan is selected from the management platform for execution.

[0064] When a temporary power outage occurs, low-voltage non-stop power operation is required to meet the continuity requirements of power supply. In the embodiment of the present application, the low-voltage non-stop power operation method includes: when a fault power outage alarm signal is received, first detect whether there is a low-voltage non-stop power operation request to detect whether there is an ongoing operation that requires continuous power supply; when there is a low-voltage non-stop power operation request, determine the corresponding power outage station area according to the low-voltage non-stop power operation request, and then judge whether the power outage station area meets the load requirements of the low-voltage contact station area to determine that the power support provided by the low-voltage contact station area meets the load requirements of the power outage station area when the non-stop power operation is performed, thereby ensuring the reliability of the low-voltage non-stop power operation method; when it is determined that the power outage station area meets the load requirements of the low-voltage contact station area, the contact distance of the power outage station area is calculated and the cable laying required for the low-voltage non-stop power operation is determined, and the first A low-voltage non-stop power operation plan does not require construction personnel to manually formulate it based on personal work experience and previous data, which reduces the labor cost of low-voltage non-stop power operation and improves the efficiency of low-voltage non-stop power operation. The first low-voltage non-stop power operation plan is scored using a feature scaling evaluation algorithm to obtain a recommended score, and the reliability of the first low-voltage non-stop power operation plan is judged based on the recommended score; when the recommended score is greater than the preset score threshold, the first low-voltage non-stop power operation plan is uploaded to the management platform and stored in the historical database, which can uniformly collect and manage the first low-voltage non-stop power operation plan, provide reliable historical data for construction personnel, improve the visualization of historical data, and avoid relying entirely on the personal experience of construction personnel to implement low-voltage non-stop power operation. The low-voltage non-stop power operation method can be driven by data support, and the reliability of the low-voltage non-stop power operation method can be further improved. In response to the first execution signal of the low-voltage non-stop power operation, the optimal first low-voltage non-stop power operation plan is selected from the management platform for execution, ensuring the smooth progress of the low-voltage non-stop power operation, minimizing the impact of power outages on users, meeting the requirements of power supply continuity, and improving user experience.

[0065] In some embodiments of the present application, a first low-voltage non-stop power operation plan is generated based on the communication distance and the cable laying. It can be understood that the first low-voltage non-stop power operation plan includes a variety of low-voltage non-stop power operation plans that meet the load requirements. The first low-voltage non-stop power operation plan is scored using a feature scaling evaluation algorithm to obtain a recommended score. The recommended score is used to determine the feasibility and recommendation of the various low-voltage non-stop power operation plans that meet the load requirements. When the recommended score is greater than a preset score threshold, the first low-voltage non-stop power operation plan is uploaded to the management platform and stored in a historical database; in response to a first execution signal of the low-voltage non-stop power operation, the management platform displays the top three recommended scores of the three first low-voltage non-stop power operation plans for construction personnel to judge and select the optimal first low-voltage non-stop power operation plan, further improving the reliability of the low-voltage non-stop power operation method; in response to the execution signal of the optimal low-voltage non-stop power operation plan, the optimal first low-voltage non-stop power operation plan is selected from the management platform for execution.

[0066] In some embodiments of the present application, the low-voltage non-stop power operation method also includes: when a fault power outage alarm signal is received, detecting whether there is a low-voltage non-stop power operation request; when there is no low-voltage non-stop power operation request, using medium-voltage transfer to solve the power supply continuity problem, so as to reduce the impact of power outages on users.

[0067] Reference Figure 2 As shown, Figure 2 The present invention provides a flowchart of a low-voltage non-stop power supply operation method when the shutdown station area does not meet the load requirements of the low-voltage contact station area, and the low-voltage non-stop power supply operation method when the shutdown station area does not meet the load requirements of the low-voltage contact station area includes but is not limited to steps S800 to S1100. Specifically,

[0068] Step S800: When the outage area does not meet the load requirements of the low-voltage contact area, a low-voltage generator vehicle power supply instruction is issued;

[0069] Step S900: In response to the low-voltage power generation vehicle power supply instruction, recommend a parking location for the low-voltage power generation vehicle;

[0070] Step S1000: Calculate the distance between the parking point of the low-voltage generator vehicle and the parking area;

[0071] Step S1100: When the distance between the parking point of the low-voltage generator vehicle and the parking area is less than a first distance threshold, a low-voltage generator vehicle that meets the load requirements of the parking area is recommended according to the load requirements of the parking area.

[0072] When there is a request for low-voltage non-stop power supply operation, determine the outage station area corresponding to the low-voltage non-stop power supply operation request, and then judge whether the outage station area meets the load requirements of the low-voltage contact station area. When the outage station area does not meet the load requirements of the low-voltage contact station area, it is reminded that low-voltage contact and power supply between stations cannot be carried out, and it is recommended to take other measures to ensure the continuity and reliability of power supply, such as using a generator truck to supply power.

[0073] In some embodiments of the present application, when the parking area does not meet the load requirements of the low-voltage contact area, the low-voltage non-stop power supply operation method includes: issuing a low-voltage generator car power supply instruction, responding to the low-voltage generator car power supply instruction, and recommending the parking point of the low-voltage generator car. Calculate the distance between the recommended parking point of the low-voltage generator car and the parking area, and determine whether the distance between the parking point of the low-voltage generator car and the parking area is less than the first distance threshold to ensure that the low-voltage generator car can effectively provide power to the parking area; when the distance between the parking point of the low-voltage generator car and the parking area is less than the first distance threshold, it meets the power supply requirements of the low-voltage generator car. At this time, according to the load requirements of the parking area, recommend the best low-voltage generator car parking point that meets the load requirements of the parking area. The best low-voltage generator car parking point facilitates the generator car to access the power grid, minimizes the impact on the surrounding area, and continuously provides power for the parking area to carry out non-stop power supply operations, ensuring the smooth progress of low-voltage non-stop power supply operations, minimizing the impact of power outages on users, meeting the requirements of power supply continuity, and improving user experience.

[0074] It should be noted that in some embodiments of the present application, the first distance threshold is 250 meters. When the distance between the parking point of the low-voltage generator and the parking area is less than 250 meters, it is determined that the low-voltage generator meets the load requirements of the parking area and can meet the power demand of the parking area. Those skilled in the art can set the size of the first distance threshold according to the geographical location of the parking area and the load requirements of the parking area. The embodiment of the present application does not limit the size of the first distance threshold.

[0075] The low-voltage non-stop power operation method provided by the present application can provide corresponding low-voltage non-stop power operation schemes according to the two situations that the shutdown station area meets the load requirements of the low-voltage contact station area and the shutdown station area does not meet the load requirements of the low-voltage contact station area, thereby improving the diversity of low-voltage non-stop power operation methods. It can be understood that when the shutdown station area meets the load requirements of the low-voltage contact station area, the low-voltage contact station area provides electricity to the shutdown station area; when the shutdown station area does not meet the load requirements of the low-voltage contact station area, the low-voltage generator truck provides electricity to the shutdown station area. Both power supply methods can continuously provide power for the shutdown station area to perform non-stop power operations, ensuring the smooth progress of low-voltage non-stop power operations, meeting the requirements of power supply continuity, and improving user experience.

[0076] In another embodiment of the present application, when the outage area does not meet the load requirements of the low-voltage contact area, the low-voltage non-stop operation method further includes step S1200, specifically,

[0077] Step S1200: When the distance between the parking spot of the low-voltage generator vehicle and the parking area is greater than a first distance threshold, a prompt message indicating that the cable laying is too long is sent to prompt another parking spot for the low-voltage generator vehicle.

[0078] When there is a low-voltage non-stop power supply operation request, the parking station area corresponding to the low-voltage non-stop power supply operation request is determined. When the parking station area meets the load requirements of the low-voltage contact station area, the distance between the recommended parking point of the low-voltage generator car and the parking station area is calculated, and it is determined whether the distance between the parking point of the low-voltage generator car and the parking station area is less than the first distance threshold, so as to ensure that the low-voltage generator car can effectively provide power to the parking station area. When the distance between the parking point of the low-voltage generator car and the parking station area is greater than the first distance threshold, it indicates that the parking station area does not meet the load requirements of the low-voltage contact station area. When the parking station area does not meet the load requirements of the low-voltage contact station area, there will be a problem of long cable laying. The cable is too long, which may reduce the power supply efficiency. It may also increase the risk of cable damage and insulation aging due to the long cable length. At this time, the low-voltage non-stop power supply operation method includes sending a prompt message that the cable is too long to prompt the construction personnel to select another parking point for the low-voltage generator car to avoid potential problems caused by the long cable laying, such as voltage drop, reduced power supply efficiency and increased safety risks, thereby improving the safety and reliability of the low-voltage non-stop power supply operation method.

[0079] Reference Figure 3 As shown, Figure 3 1 is a flowchart of a low-voltage non-stop power operation method provided by another embodiment of the present application. The low-voltage non-stop power operation method includes but is not limited to steps S1110 to S1140. Specifically,

[0080] Step S1110: Generate a cable laying path according to the distance from the parking point of the low-voltage generator vehicle to the parking area and the configuration capacity corresponding to the low-voltage generator vehicle that meets the load requirements of the parking area;

[0081] Step S1120: generating a second low-voltage non-stop power supply operation plan according to the correspondence between the distance from the parking point of the low-voltage generator vehicle to the parking station area and the cable laying path;

[0082] Step S1130: uploading the second low-voltage non-power-off operation plan to the management platform and storing it in the history database;
