Embodiment 1

[0045] The following is an introduction to Embodiment 1 of a planning method for wiring lines of a distribution network provided by the present application, see figure 1 , embodiment one includes:

[0046] Step S101: Perform grid division on the target distribution network area to obtain multiple grids.

[0047] The distribution network is an important part of the power grid system. The distribution network is mainly oriented to user terminals to provide continuous, stable and reliable power supply services to user terminals. In this embodiment, the target distribution network area refers to the area where wiring line planning is to be performed, and the area includes power supply equipment and power consumption equipment. Specifically, the power supply equipment may be a substation.

[0048]The so-called grid division is to decompose and divide the distribution network area into relatively independent and non-overlapping grids according to roads or geographical locations, an...

Embodiment 2

[0057] see figure 2 , embodiment two specifically includes:

[0058] Step S201: Perform grid division on the target distribution network area to obtain a power grid including substations in the area where the grids are located and a load grid not including substations in the area where the grids are located.

[0059] Step S202: Classify the load grids according to the load types, and merge the load grids of the same type and located adjacent to each other.

[0060] As mentioned above, this embodiment subdivides the load grid into multiple types according to the load type, and merges the load grids of the same type and adjacent positions. On the one hand, it saves the calculation amount of the subsequent process, on the other hand , which overcomes the problem in the prior art that only considers the load power and does not consider the importance of the load, and is more suitable for actual scene requirements, where the load type can be industrial, commercial, government age...

Embodiment approach

[0109] As a specific implementation, the device also includes:

[0110] Distance modification module: used to modify the distance between two path nodes whose construction difficulty is greater than the preset threshold to infinity

[0111] A distribution network wiring line planning device in this embodiment is used to implement the aforementioned distribution network wiring line planning method, so the specific implementation of the device can be seen in the previous distribution network wiring line The embodiment part of the planning method, for example, the grid division module 501, the distance determination module 502, and the optimal connection line determination module 503 are respectively used to implement steps S101, S102, and S103 in the above-mentioned method for planning a distribution network connection line . Therefore, for the specific implementation manners thereof, reference may be made to the descriptions of the corresponding partial embodiments, and no fur...

Abstract

The invention discloses a planning method for a power distribution network wiring line. The method comprises the steps: performing the grid division of a target power distribution network region, abstracting the grids as path nodes, further determining the distances between the path nodes and the power distribution loads of the path nodes, and finally determining the optimal wiring line of the path nodes in the target power distribution network region by utilizing an ant colony algorithm according to the power distribution loads of the path nodes, the distances between the path nodes and the maximum load capacity of the line. Therefore, the method utilizes the ant colony algorithm to iteratively optimize and solve the wiring line of the plurality of nodes in the power distribution network.Due to the fact that the ant colony algorithm can summarize the information harvested in the iteration process every time after the iteration process, a reference is provided for the subsequent iteration process, thereby remarkably increasing the planning speed after the ant colony algorithm is used for power distribution network planning, and saving the planning time. In addition, the inventionfurther provides a planning device and equipment for the power distribution network wiring line and a computer readable storage medium, wherein the functions of the device and equipment are corresponding to those of the method.

Description

technical field [0001] The present application relates to the field of power grid planning, and in particular to a planning method, device, equipment and computer-readable storage medium for distribution network wiring lines. Background technique [0002] Most of the traditional distribution network planning adopts a top-down method, divergent planning to the distribution network with the main network as the core, adopts fragmented layout, does not consider long-term and overall planning, and it is difficult to achieve overall reliability and economy best. With the advancement of power system reform, the distribution network needs to efficiently meet the needs of power customers for high-quality power supply services with limited construction investment. Safe and reliable, flexible grid operation. [0003] At present, the country has begun to adopt the concept of grid-based planning for planning and design, breaking the fragmented layout, dividing the grid with the idea of...
