[0023] Figure 1 is a flowchart of a CAD platform-based power distribution system design method according to an embodiment of the present application. As shown in Figure 1 , the method comprises the following steps:

[0024] Step S101, reading the grid and power points in CAD, obtaining the grid coordinates and power point information, calculating the optimal bridge position, generating the bridge in the optimal bridge position in CAD, wherein the power point information includes power point coordinates, power and name;

[0025] Specifically, the user boxes the grid and power point tiles of the building. Then the coordinates of the grid, the coordinates, power, name and the like of the power point are read from the inside of the CAD. The appropriate coordinates of each point can be determined according to the grid.

[0026] In step S102, the bridge is read in CAD to obtain bridge information, the load center of the power consumption point is calculated according to the bridge information and the power consumption point information, and the distribution box is generated in CAD according to the load center, wherein the bridge information includes bridge endpoint coordinates and bridge specifications.

[0027] Specifically, the load center of the power consumption point is calculated in batches by using the cluster algorithm and the point regression algorithm, and the distribution box entity is generated on the side of the nearest column.

[0028] In step S103, the bridge is read in CAD, and the bridge is disassembled into point coordinates and line segments, wherein the point coordinates are the coordinates of the bridge nodes, the line segments are the line segments between the bridge nodes, and the bridge nodes are the start point, end point and inflection point of the bridge.

[0029] Specifically, the entity of the bridge is read from CAD, and the arrangement information of the bridge is disassembled into a set of point coordinates and line segments, and the bridge between every two bridge nodes is regarded as a line segment.

[0030] In step S104, the distribution box is read in CAD to obtain distribution box information, and all distribution paths from the distribution box to the power consumption point are generated according to the distribution box information and the power consumption point information, and the length of the distribution path is calculated, wherein the distribution box information includes distribution box coordinates and distribution box name.

[0031] Specifically, the distance between each point and the end point and the last node is calculated point by point, and finally the shortest distance from the start point to the end point is calculated.

[0032] In step S105, a best path is selected from all the distribution paths, and the best path is generated in CAD to obtain the final distribution system diagram, cable length and main material list.

[0033] Specifically, the user can select the best path from all the generated distribution paths, or directly select the shortest distribution path as the best path, or the user can draw it by himself.

[0034] Through the embodiment, the automatic drawing and multiple path selection of the cable path are realized, the workload and time cost of manual drawing are reduced, especially in the complex design of multiple power consumption points, the advantage is more obvious, the connection point coordinates, path selection and information statistics are automatically calculated, the error rate caused by manual operation is reduced, and the design accuracy is improved.

[0035] In an optional embodiment, when the bridge is arranged east-west, and the weighted sum of the distance from each power consumption point to the bridge is the minimum, the best bridge position is determined according to the formula The endpoint coordinates of the best bridge position are And Wherein, is the minimum value of the weighted sum of the distance from each power consumption point to the bridge. is the number of the power consumption point, is the power of the power consumption point, is the ordinate of the power consumption point, is the value of the abscissa of the power consumption point with the minimum abscissa among all the power consumption points, is the value of the abscissa of the power consumption point with the maximum abscissa among all the power consumption points, is the number of the power consumption points; when the bridge is arranged in the east-west direction or the north-south direction, and the weighted sum of the distances from each power consumption point to the bridge is the minimum, the optimal bridge position is determined according to the formula the end point coordinates of the optimal bridge position are and wherein, is the abscissa of the power consumption point, is the value of the ordinate of the power consumption point with the minimum ordinate among all the power consumption points, is the value of the ordinate of the power consumption point with the maximum ordinate among all the power consumption points.

[0036] Specifically, the bridge is arranged in the east-west direction or the north-south direction. The distance between each power consumption point and the bridge is calculated by a linear regression algorithm. Finally, the line with the minimum variance is obtained as the bridge position. The distance from the bridge to the power consumption point is minimized, thereby saving space and materials in actual laying. The laying difficulty of the short-distance cable is lower, and the line loss heating is reduced, thereby reducing the probability of two types of faults and indirectly improving the stability of the power supply system. The cable path is short and direct, and in the later maintenance (such as troubleshooting and cable replacement), there is no need to trace a long detour path, thereby shortening the maintenance time.

[0037] In an alternative embodiment, a preset number of power consumption points are randomly determined as cluster centers, and each power consumption point is divided into the same cluster with the cluster center closest to it.

[0038] Specifically, the division of the cluster can reduce the calculation pressure. In the selection of the load center, each cluster can be selected, and the calculation is more rapid and accurate.

[0039] In an alternative embodiment, the sum of the Euclidean distances from each power consumption point in the cluster to the corresponding cluster center is calculated to obtain the cluster distance. The cluster center corresponding to the minimum cluster distance is determined as the position of the distribution box, and the calculation formula is , is the number of the power consumption points in the cluster, is the abscissa of the power consumption point, is the ordinate of the power consumption point, is the coordinate of the distribution box.

[0040] Specifically, this is through the cluster algorithm to calculate the load center to determine the distribution box coordinates. Distribution box as cluster center, its capacity can be designed according to the total power in the cluster (∑Pi): avoid "big box small use" (such as use 200A distribution box with 50A load, waste equipment cost) or "small box big use" (such as use 100A distribution box with 150A load, overload trip risk); can be targeted configuration protection device (such as leakage protector, overcurrent relay), and protection parameters and cluster load matching (such as high power cluster configuration high rated current circuit breaker), improve the safety of power supply.

[0041] In an alternative embodiment, the Manhattan distance of each power point to the cluster center corresponding to the power point is calculated, and when the bridge position is east-west, the calculation formula is , and when the bridge position is north-south, the calculation formula is , wherein is the Manhattan distance, is the horizontal coordinate of the power point, is the vertical coordinate of the power point, is the horizontal coordinate of the distribution box, is the vertical coordinate of the distribution box, is the horizontal coordinate of the bridge node, is the vertical coordinate of the bridge node; when the weighted sum of the distance from each power point to the bridge is the minimum, the distribution box position corresponding to the Manhattan distance corresponding to the power point is determined as the load center, and the calculation formula is , wherein is the minimum value of the weighted sum of the distance from each power point to the bridge, is the power of the power point.

[0042] Specifically, this is through the point regression algorithm to calculate the load center to determine the distribution box coordinates. The core advantage of this method is to replace the ideal straight-line distance with the Manhattan distance (Di), which is more in line with the actual wiring constraints of building power distribution system. In practical engineering, cables need to be arranged along walls, bridges, floors / ceiling, etc. "right angle path", and the calculation formula of Di (such as under the east-west bridge) exactly simulates the right angle wiring path of "power point→bridge→distribution box", avoiding the deviation of ideal distance and actual path. At the same time, the model is weighted by (power of power point), so that high-power power points (core load) have higher influence weight on the load center. The load center corresponding to the calculation of after weighting can preferentially meet the "short-distance power distribution demand" of core load, and the positioning accuracy is much higher than that of "non-weighted / equal-weighted" calculation method.

[0043] In an alternative embodiment, the neighbor nodes of each distribution box and each bridge node are acquired, wherein the neighbor nodes are the bridge nodes and power consumption point coordinates connected to the distribution box or the bridge node through a line segment; in step S601, one neighbor node of each distribution box and each bridge node is randomly selected until the power distribution path is obtained by connecting to the power consumption point coordinates corresponding to the distribution box; and step S601 is repeatedly executed until all power distribution paths and path lengths are acquired.

[0044] Specifically, the routing algorithm is used to randomly select a neighbor node from the distribution box, and then select a neighbor node through the bridge node until the power consumption point is connected. By repeating the selection, each feasible route can be selected, and finally the best path is confirmed according to the user's demand. In order to avoid waste of computing power, the node connected back should not be selected when selecting the neighbor node.

[0045] The application realizes automatic drawing of cable paths and multiple path selection, reduces the workload and time cost of manual drawing, and the advantage is more obvious especially in complex design of multiple power consumption points. By automatically calculating the connection point coordinates, path selection and information statistics, the error rate caused by manual operation is reduced, and the accuracy of the design is improved. During drawing, a data list and related tables are automatically generated, and appropriate circuit breakers, cables and other specifications can be automatically selected according to electrical information, which provides more scientific and accurate basis for designers and avoids problems caused by improper specification selection.

[0046] The embodiment of the application also provides a power distribution system design device based on a CAD platform. It should be noted that the power distribution system design device based on the CAD platform can be used to execute the power distribution system design method based on the CAD platform.
