Detailed Description
For better understanding of the objects, technical solutions and effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples. It is to be noted that the following examples are given for the purpose of illustration only and are not intended to limit the invention
Example one
Fig. 1 is a flowchart of a method for determining a required quantity for building a cable tunnel of a power distribution network according to a first embodiment, and is characterized by including the steps of:
s101, acquiring a road network intersection point and a cable line planning path in a power distribution network functional area; the road network intersection points are intersection position points of different roads in the power distribution network functional area;
the road in the power distribution network functional area is a road capable of being provided with a cable line, such as a main road or a secondary main road. The planned path of the cable line is an actual path determined according to a networking scheme in advance.
Fig. 2 is a schematic diagram of a road network in a functional area of a7 × 7 power distribution network, and for convenience of viewing and understanding of the present embodiment, the road network in the functional area of the 7 × 7 power distribution network in fig. 2 is taken as an example, and the network is drawn in a regular form staggered from a cross. As shown in fig. 2, each point such as "a 1-a 7" or "B1-B7" is a road network intersection, and the path L1 is a cable route planning path.
S102, correcting the planned path into a connecting line of each corresponding road network intersection point according to the distance between the planned path and the road network intersection point to obtain a corrected planned path;
in one embodiment, the distance between each point and the planned path is calculated, a point with the distance from the planned path being less than the preset distance is selected, and a connecting line obtained by connecting the point with the distance being less than the preset distance is the corrected planned path. As shown in fig. 2, the path L2 is the revised planned path, where the points smaller than the preset distance are "B2, C2, C3, C4, D4, E4, E5, D5, D6, E6, F6, and G6" in sequence.
In another embodiment, the planned path L1 may be further simulated by an image algorithm to modify the planned path L2.
S103, determining the number of cables between each two adjacent road network intersections according to the number of times that the revised planning path passes through each road network intersection;
in this embodiment, the planned path may include multiple paths that are the same or different, and the multiple corresponding revised planned paths may pass through any one of the rational network intersections. If n different cable lines exist at the intersection point of two adjacent road networks, the number of the cables is n.
For better understanding of the present embodiment, the following explanation is made by using a7 × 7 distribution network functional area road network shown in fig. 2. Definitions X, Y are transverse and longitudinal length matrices, respectively, where the transverse and longitudinal directions of the 7 × 7 power distribution network functional area road network can be various combinations, such as transverse direction is east direction of the actual functional area, then longitudinal direction can be north direction or south direction of the actual functional area, if transverse direction is north direction of the actual functional area, then longitudinal direction can be east direction or west direction of the actual functional area, and so on. Based on this, the transverse matrix X and the longitudinal matrix Y are respectively:
wherein, Xm、YnRespectively the length vector of the mth transverse axis and the length vector of the nth longitudinal axis, xm,n-1Is the length between the nth road network intersection and the (n-1) th road network intersection on the mth horizontal axis, ym-1,nIs the length between the (m-1) th road network intersection point and the mth road network intersection point on the nth longitudinal axis.
In one embodiment, if two adjacent road network intersections coincide, the length between the two adjacent road network intersections is zero; if the road between two adjacent road network intersections is interrupted, the length between the two adjacent road network intersections is infinite. Y1,1 is 0 if points a1 and a2 coincide, and x7,6 is 0 if points F7 and G7 coincide; further, in the case of a break in the road, such as a break between B4 and B6, y4,2 and y5,2 are all equal to infinity. On the basis, the method is favorable for avoiding roads where cable lines cannot be laid, and improves the practical construction feasibility of the construction demand of the cable tunnel.
In one embodiment, the method for determining the required quantity for building the cable tunnel of the power distribution network further comprises the following steps:
and if the construction demand of the cable tunnel is infinite, correcting and correcting the planned path.
If the construction demand of the cable tunnel is infinite, it indicates that the cable line passes through the interrupted road. Based on this, the revised planned path can be modified by changing the intersection point of the road network through which the revised planned path passes. Optionally, the intersection points of the road network through which the revised planned path passes may be changed one by one until the construction demand of the cable tunnel is not infinite.
By correcting and correcting the planned path, when the planned path of the cable line passes through the interrupted road, the planned path is corrected and corrected in time to obtain a correct corrected planned path, so that the construction demand of the obtained cable tunnel conflicts with the actual road.
Based on the transverse length matrix X and the longitudinal length matrix Y in the functional area road network of the 7 × 7 distribution network of fig. 2, h (a) is defined as a transverse path matrix of the a-th line, and z (a) is defined as a longitudinal path matrix of the a-th line, as follows:
wherein, H (a)m、Z(a)nRespectively, a path vector of the a-th line on the m-th transverse axis and a length vector of the n-th longitudinal axis, h (a)m,n-1The number of times that the a-th line passes through the (n-1) -th grid intersection point and the n-th grid intersection point from left to right on the m-th horizontal axis, z (a)m-1,nThe number of times that the a-th line passes through the intersection point of the m-th grid and the intersection point of the (m-1) -th grid from bottom to top on the nth longitudinal axis is shown.
And S104, determining the construction demand of the cable tunnel by combining the number of the cables and the length between the intersection points of each two adjacent road networks.
The method comprises the following steps of determining the number of cable tunnels between any two adjacent road network intersections according to the number of cables; according to the length between every two adjacent road network intersections, the length of the cable tunnel between any two adjacent road network intersections can be determined. According to the total number of the cable tunnels and the corresponding length, the construction demand of the cable tunnels can be determined. That is, the construction requirement of the cable tunnel includes the number of the cable tunnels and the length of the cable tunnel.
The explanation here is given with reference to the transverse length matrix X and the longitudinal length matrix Y in the road network based on the 7 × 7 power distribution network functional area of fig. 2. Definition of LHAnd LZThe quantity matrixes of the transverse roads and the longitudinal roads passing through the cable lines respectively are that the quantity matrix of the cable lines on each road for the construction of the cable tunnel is as follows:
where a is the total number of lines, ia is the number of cable lines of the a-th line, and ia is generally 1. Wherein the construction demand of the cable tunnel is LHAnd LZAnd (4) summing.
In one embodiment, the method for determining the required quantity for building the cable tunnel of the power distribution network further comprises the following steps:
and correcting the construction demand of the cable tunnel according to the electrical room distribution points.
Considering that a typical design of a cable tunnel cannot cover all areas, not only a tunnel form with a larger scale needs to be revised, but also a certain margin needs to be considered according to practical situations, and a cable tunnel with a proper scale also needs to be reserved for a road without planned lines or optical fibers in a functional area network. Based on this, the construction demand of the cable tunnel is corrected by obtaining the product of the preset correction coefficient and the construction demand of the cable tunnel, and taking the product of the preset correction coefficient and the construction demand of the cable tunnel as the actual construction demand of the cable tunnel.
The method for determining the construction demand of the cable tunnel of the power distribution network according to the embodiment determines the relationship between the planned path of the cable line and the construction demand of the cable tunnel based on the determined planned path of the cable line and by combining with the intersection point of the road network in the functional area of the power distribution network, and accurately counts the construction demand of the cable tunnel so as to guide the actual construction of the cable tunnel in the functional area of the power distribution network.

wherein P is the highest load of the functional area, E is the coincidence rate, and U is the total number of the plots.
After the power load distribution of each independent area is calculated, the electric room distribution can be carried out by combining the power loads of each land.
And S202, planning a cable route planning path according to the electric room distribution points.
The determined electric room distribution points comprehensively consider the power loads of the independent areas, so that the determination of the electric room distribution points restricts the power supply capacity and the networking scheme of the cable line, and the path planning of the cable line is carried out according to the restricted power supply capacity and the networking scheme of the cable line, so that the construction demand of the cable tunnel obtained through subsequent calculation can be more fit with the actual demand of the networking of the power distribution network.
