Problems solved by technology

EHV and UHV transmission lines are long and have a large number of towers. If there is no visual tool that can manage and edit line towers in a unified manner, editing the information of all towers and calculating the equivalent circuit of different types of towers will be inefficient and error-prone

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as figure 1 As shown, the novel tower editor of the present invention adopts object-oriented programming, has a friendly interactive interface, and the construction method includes the following steps:

[0038] 1) Summarize and sort out the types of towers currently used in power system transmission lines, and abstract the common attributes of various towers, including the expression method of structure size, the type of hanging method of the ground wire of the tower, the calculation model of the tower circuit, and the parameters of the insulator string of the tower, based on The common attributes of towers establish a virtual base class, and determine the rules describing the geometric dimensions of towers, the way of hanging ground wires, the circuit model of towers and the parameters of tower insulator strings;

Abstract

The invention discloses an establishing method of a novel two-dimensional tower editor and a tower modeling method. According to the tower editor, objected-oriented programs are adopted, various tower attributes are abstracted, a virtual base class tower description attribute and method are established, different types of tower description files (.XML format) are derived, and the parameters of a tower model can be calculated automatically by visual editing and tower instantiating. The establishing method of the novel two-dimensional tower editor and the tower modeling method are mainly used for lightning protection performance analysis tower modeling work of an electric transmission line so as to improve the lightning protection analysis modeling efficiency of the electric transmission line.

Description

technical field [0001] The invention belongs to the field of lightning protection analysis and modeling of transmission lines, and in particular relates to a construction method of a novel two-dimensional pole tower editor and a pole tower modeling method. Background technique [0002] Lightning strike has always been a hazard factor of great concern to power systems, and is the primary environmental factor causing line trips. In recent years, with the expansion of the grid scale and the increase of the voltage level, the probability of the line being struck by lightning has also increased; The micro-meteorological environment also makes frequent lightning accidents on transmission lines. The China Southern Power Grid is a lightning-prone area, especially in recent years, the lightning activity has shown an obvious growth trend. With the continuous improvement of society's demand for safe power supply and power quality, higher requirements are put forward for the preventio...
