Method and device for optimizing tower structure of power distribution network

Abstract

The invention discloses a power distribution network tower structure optimization method and device. The method comprises the steps of obtaining information collection information of a power distribution network; determining the wire model of each feed circuit in the power distribution network; judging the tension property of each rod site in the power distribution network, and generating a tension section of each feed circuit; calculating a representative span of each strain section, and judging whether an isolated span exists in the feed circuit or not according to the representative span; determining the electric pole type of each pole site, calculating the K value of each pole site, and calculating the sag value of the wire between two adjacent pole sites according to the K value; determining the pole tower model of each pole position point according to the sag value; according to the method, the wire model, the tension attribute of the pole site, the K value of the pole site and the like in the power distribution network are designed in sequence, calculation of the pole structure in the power distribution network can be processed and standardized, dependence of design of the power distribution network on knowledge reserve and experience of a designer is reduced, design risks are avoided, and design efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electric power distribution network, and in particular relates to a method and a device for optimizing the structure of a distribution network pole and tower. Background technique [0002] Pole and Tower is an important part of the distribution network. It supports overhead transmission line conductors and overhead ground wires and keeps a certain distance between them and the ground. Line towers around the world adopt steel structure, wood structure and reinforced concrete structure. Usually the rod-shaped structure of wood and reinforced concrete is called a pole, and the tower-shaped steel structure and reinforced concrete chimney-shaped structure are called towers. [0003] In the initial design of the distribution network, it is usually necessary to optimize the tower structure, and in the process of optimizing the tower structure, cross arms and guy wires are usually involved. Usually, the design ...

Problems solved by technology

[0004] However, this type of design method requires the designer to have a wealth of knowledge and experience reserves, otherwise, the design process will often be reworked, resulting in cumbersome design process and prolonging the design cycle of the distribution network.

Moreover, design based on artificial experience will usually produce different design results for different designers, which will lead to some design schemes not rigorous enough, which will easily cause design risks
