[0029] Embodiment 1

[0030] Figure 1 A flowchart of a method for locating a distribution transformer is provided for Embodiment 1 of the present invention. This embodiment is applicable to the situation of locating a newly added distribution transformer based on the location information and load information of load points in a substation area. This method can be executed by a device for locating a distribution transformer, which can be implemented in the form of hardware and / or software, and can be configured in various general computing devices. As Figure 1 shown, the method includes:

[0031] S110. Obtain the location information and load information of load points in the target substation area associated with the initial distribution transformer.

[0032] The target power distribution area is the power supply area served by the initial distribution transformer. The target power distribution area includes multiple load points, and the initial distribution transformer is used to supply power to the multiple load points in the target power distribution area. When the load exceeds the set load threshold when the initial distribution transformer supplies power to multiple load points in the target power distribution area, for example, the set load threshold is 80%, in order to avoid damage to the initial distribution transformer or unstable power supply, it is necessary to add a new distribution transformer in the target power distribution area to share the load of the initial distribution transformer.

[0033] In the embodiments of the present invention, in order to select a location for the newly added distribution transformer, first, it is necessary to obtain the location information and load information of the load points in the target power distribution area associated with the initial distribution transformer. Specifically, the location information of the load points in all branches downstream of the initial distribution transformer can be obtained by calling the Geographic Information Service (GIS for short). Among them, the Geographic Information Service is used to provide any spatial information at any time and any place for users, and the location information of the load points is stored corresponding to the identifiers of the load points in the Geographic Information Service.

[0034] Furthermore, according to the identifier of each load point, call the data service to obtain the load information of each load point. Among them, the data service is used to provide the operation data in the power system for users, including the load information of each load point, etc.

[0035] S120. Determine the load center according to the location information and load information of the load points in the target power distribution area.

[0036] The load center is the concentrated area of power consumption. In order to enable the newly added distribution transformer to deliver power to the load points in the target power distribution area with as little transportation loss as possible, in the embodiments of the present invention, it is necessary to first determine the load center to determine the address of the newly added distribution transformer according to the load center.

[0037] Determine the load center according to the location information and load information of the load points in the target power distribution area obtained in S110. Specifically, first, according to the load information of each load point in the target power distribution area, determine the load weight of each load point. Among them, the greater the load of the load point, the higher the corresponding load weight. Furthermore, based on the load weight, perform a weighted sum of the location information of the load points in the target power distribution area to obtain the load center. By considering the load weight, determining the load center as the basis for the location selection of the newly added distribution transformer can reduce power transportation loss and improve power supply stability.

[0038] It is also possible to select at least one load point to be migrated in the target power distribution area, and then determine the weights of the load points to be migrated according to the load information of the load points to be migrated. Among them, the larger the load of the load point to be migrated, the higher the corresponding load weight. Further, based on the load weights, the position information of at least one load point to be migrated is weighted and summed to obtain the load center.

[0039] In a specific example, the target power distribution area includes n load points, and the position information of each load point is in the form of longitude and latitude. First, calculate the sum of the loads of the n load points, and use the ratio of the load of each load point to the sum of the loads as the load weight of the load point. Further, based on the load weights, the longitudes of the load points are weighted and summed to obtain the longitude of the load center; the latitudes of the load points are weighted and summed to obtain the latitude of the load center.

[0040] S130. Based on the load center, select a location for the newly added distribution transformer; the newly added distribution transformer is used to share the load of the initial distribution transformer.

[0041] In the embodiment of the present invention, after determining the load center, based on the load center, select a location for the newly added distribution transformer to enable the newly added distribution transformer to share part of the load of the initial distribution transformer. Specifically, a circular area can be generated with the load center as the center and a set length as the radius. Then, the unavailable areas are removed from the circular area to obtain the candidate area. Among them, the unavailable areas can be water systems, highways, railways, farmland areas, and land use under regulatory planning, etc.

[0042] Further, determine at least one plot in the candidate area that can accommodate the newly added distribution transformer, and randomly select one of the available plots as the construction address of the newly added distribution transformer.

[0043] It is also possible to calculate the distance between each plot and the load center after determining at least one plot in the candidate area that can accommodate the newly added distribution transformer, and select the available plot with the shortest distance to the load center as the construction address of the newly added distribution transformer.

[0044] The technical solution of the embodiment of the present invention obtains the position information and load information of the load points in the target power distribution area associated with the initial distribution transformer, and then determines the load center according to the position information and load information of the load points in the target power distribution area. Finally, based on the load center, select a location for the newly added distribution transformer to share the load of the initial distribution transformer. By determining the load center and selecting a location for the newly added distribution transformer based on the load center, it is not necessary to visit manually, which can reduce the workload of location selection and improve the efficiency of location selection.

[0045] Embodiment 2

[0046] Figure 2The flowchart of a distribution transformer site selection method provided in the second embodiment of the present invention. This embodiment is further refined on the basis of the above embodiment, and provides specific steps for determining the load center according to the position information and load information of load points in the target substation area, and specific steps for site selection of a newly added distribution transformer based on the load center. As Figure 2 shown, the method includes:

[0047] S210. Obtain the position information and load information of load points in the target substation area associated with the initial distribution transformer.

[0048] S220. Determine the load weight of each load point according to the load information of load points in the target substation area.

[0049] If the load center is calculated only based on the position information of load points in the target substation area, the load center can only represent the central position of multiple load points in the target substation area. It may occur that the distance between the load center and the load point with a large load is far, and the distance between the load center and the load point with a small load is close.

[0050] In order to enable the load center to be located in the area where power consumption is concentrated, in the embodiment of the present invention, the load weight of each load point is determined according to the load information of load points in the target substation area. Among them, the greater the load of the load point, the higher the load weight.

[0051] For example, calculate the proportion of the load of each load point in the total load of the target substation area as the load weight of the load point. Another example is that the weight of the load point can be determined by using the softmax normalization algorithm based on the load information of each load point.

[0052] Optionally, determining the load weight of each load point according to the load information of load points in the target substation area includes:

[0053] Determine the total load of the target substation area according to the load information of load points in the target substation area;

[0054] Determine the load weight of each load point according to the load information and total load of each load point.

[0055] In this optional embodiment, a specific method for determining the load weight of each load point according to the load information of the load points in the target substation area is provided: First, according to the load information of the load points in the target substation area, the total load of the target substation area is determined. Furthermore, according to the load information and the total load of each load point, the load weight of each load point is determined. Specifically, the proportion of the load of each load point in the total load is calculated as the load weight of this load point. By calculating the proportion of the load in the total load to determine the load weight, when there are many load points in the target substation area, the weight can be calculated with a small amount of calculation, so as to accurately locate the load concentration area as the load center, and then improve the rationality of the newly added distribution transformer.

[0056] S230. Determine the load center according to the location information and load weight of the load points in the target substation area.

[0057] In the embodiment of the present invention, after calculating the load weight of each load point, the load center is determined according to the location information and load weight of the load points in the target substation area. The specific calculation formula is as follows:

[0058] Longitude of the load center = (J1 * P1 + J2 * P2 +... + Jn * Pn) / Ps

[0059] Latitude of the load center = (W1 * P1 + W2 * P2 +... + Wn * Pn) / Ps

[0060] Wherein, Jn is the longitude of the nth load point, Wn is the latitude of the nth load point, Pn is the load information of the nth load point, and Ps is the total load of the load points in the target substation area.

[0061] The load center calculated by the above formula can better represent the load concentration area in the target substation area compared with the geographical center calculated only based on the positions of each load point, and can be used as important auxiliary information for site selection.

[0062] S240. Take the load center as the center of a circle and a set length as the radius to generate a first candidate area; the set length is determined according to the floor area of the target substation area, the complexity of the power network, and the capacity of the initial distribution transformer.

[0063] In the embodiments of the present invention, in order to enable the newly added distribution transformer to provide reliable power transmission to each load point and reduce power transmission losses, a circular area is generated as the first candidate area with the load as the center and a set length as the radius, so as to continue searching for plots available for building a new distribution transformer in the first candidate area. Among them, the set length is determined according to the floor area of the target substation area, the complexity of the power network, and the capacity of the initial distribution transformer. Specifically, the set length is positively correlated with the floor area of the target substation area, negatively correlated with the complexity of the power network, and positively correlated with the capacity of the initial distribution transformer.

[0064] S250. In the first candidate area, remove the unavailable areas to obtain the second candidate area.

[0065] In the embodiments of the present invention, in the first candidate area, there will be many areas that cannot be used to build a distribution transformer, which are called unavailable areas. For example, the unavailable areas are water systems, highways, railways, farmland areas, land under regulatory planning, etc. Therefore, it is necessary to remove the unavailable areas in the first candidate area to obtain the second candidate area.

[0066] In a specific example, GIS can be called to obtain the first type of unavailable areas such as water systems, highways, railways, and farmland areas included in the first candidate area. Further, by accessing the spatio-temporal big data platform and using the control specification layer in the platform, at least one land under regulatory planning included in the first candidate area is determined as the second type of unavailable area. Finally, the first type of unavailable area and the second type of unavailable area are removed from the first candidate area to obtain the second candidate area. Among them, the control specification layer contains information such as water systems, highways, railways, farmland areas, and land under regulatory planning.

[0067] S260. According to the floor area of the newly added distribution transformer, determine at least one available plot in the second candidate area.

[0068] In the embodiments of the present invention, after removing the unavailable areas in the first candidate area, the remaining second candidate area will contain many irregularly shaped areas. And building a distribution transformer requires a certain floor area. Therefore, it is necessary to determine the plots that can be used to place the newly added distribution transformer, that is, the available plots, in the second candidate area according to the floor area of the newly added distribution transformer.

[0069] S270. Determine the address of the newly added distribution transformer among the available plots.

[0070] In the embodiments of the present invention, if there are multiple available plots in the second candidate area, one can be randomly selected from the available plots as the address for the newly added distribution transformer. It is also possible to calculate the positions of each available plot and the load center, and select the one closest to the load center as the address for the newly added distribution transformer. It is also possible to calculate the distances between each available plot and the initial distribution transformer, and select the one closest to the initial distribution transformer as the address for the newly added distribution transformer, which can reduce the workload of load point migration.

[0071] Optionally, determining the address of the newly added distribution transformer among the available plots includes:

[0072] Calculating the power supply distance between each available plot and the load center;

[0073] Determining the address of the newly added distribution transformer according to the power supply distance.

[0074] In this optional embodiment, a specific method for determining the address of the newly added distribution transformer among the available plots is provided: determining the center of each available plot, and calculating the power supply distance between the center of each available plot and the load center. The available plot with the closest power supply distance is determined as the address of the newly added distribution transformer.

[0075] The technical solution of the embodiments of the present invention determines the load weight of each load point according to the load information of the load points in the target substation area, and determines the load center according to the position information and load weight of the load points in the target substation area. Finally, with the load center as the center and a set length as the radius, a first candidate area is generated. The unavailable areas are removed from the first candidate area to generate a second candidate area. An available plot is selected from the second candidate area, and the address of the newly added distribution transformer is determined among the available plots, which can keep the distance between the location of the newly added distribution transformer and the load center within the set range, ensure the power transmission efficiency and reliability of the newly added distribution transformer, and control the power transmission loss.

As Figure 3 shown, the method includes:

[0079] S320. Extract at least one load point to be migrated from the load points in the target substation area according to the position information of the load points in the target substation area.

[0080] In an embodiment of the present invention, at least one load point to be migrated can be determined in the load points of the target distribution area in advance according to the position information of the load points in the target distribution area. Among them, the load point to be migrated is the load point planned to be migrated from the initial distribution transformer to the newly added distribution transformer.

[0081] Specifically, the distances between each load point in the target distribution area and the initial distribution transformer can be calculated, and the load points can be sorted in descending order of the distances to obtain a load point queue. Finally, the first set number n of load points are selected from the load point queue as the load points to be migrated.

[0082] It can also be to cluster the load points in the target distribution area according to the position information of the load points in the target distribution area to obtain a plurality of clustering clusters. Furthermore, the clustering cluster with the largest number of load points or the largest total load of the load points is selected from the plurality of clustering clusters as the target clustering cluster. Finally, the load points in the target clustering cluster are used as the load points to be migrated.

[0083] Optionally, extracting at least one load point to be migrated from the load points in the target distribution area according to the position information of the load points in the target distribution area includes:

[0084] Calculating the distance between each load point and the initial distribution transformer according to the position information of the load points in the target distribution area;

[0085] Extracting at least one load point to be migrated from the load points in the target distribution area according to the distance.

[0086] In this optional embodiment, a specific method for extracting at least one load point to be migrated from the load points in the target distribution area according to the position information of the load points in the target distribution area is provided: First, calculate the distance between each load point and the initial distribution transformer according to the position information of the load points in the target distribution area. Then, sort the load points in the target distribution area in descending order of the distances to obtain a load point queue. Finally, the first set number n of load points are selected from the load point queue as the load points to be migrated. By selecting the load points farther from the initial distribution transformer as the load points to be migrated. Furthermore, based on the positions of the load points to be migrated, the newly added distribution transformer can be selected, and the load points farther from the initial distribution transformer can be allocated to the newly added distribution transformer, reducing power transmission losses and improving power supply reliability.

[0087] S330. Determine the load weight of each load point to be migrated according to the load information of the load point to be migrated.

[0088] In an embodiment of the present invention, the load weight of each load point to be migrated is determined according to the load information of the load point to be migrated. Among them, the greater the load of the load point to be migrated, the higher the corresponding load weight.

[0089] For example, calculate the proportion of the load of each load point to be migrated in the total load of all load points to be migrated as the load weight of this load point to be migrated.

[0090] S340. Determine the load center according to the location information and load weight of the load points to be migrated.

[0091] In the embodiment of the present invention, after calculating the load weights of each load point to be migrated, the load center is determined according to the location information and load weights of all load points to be migrated. Specifically, based on the load weights, the location information of the load points to be migrated is weighted and summed to obtain the load center.

[0092] S350. Locate the new distribution transformer based on the load center; the new distribution transformer is used to share the load of the initial distribution transformer.

[0093] The technical solution of the embodiment of the present invention extracts at least one load point to be migrated from the load points in the target substation area according to the location information of the load points in the target substation area, and then determines the load weight of each load point to be migrated according to the load information of the load points to be migrated, and determines the load center according to the location information and load weight of the load points to be migrated. Finally, based on the load center, the new distribution transformer is located, which can make the new distribution transformer close to the load center of the load points to be migrated, share the load of the initial distribution transformer, and ensure the transmission efficiency and reliability of the new distribution transformer.
