Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] In the embodiment of the present invention, the connection mode of the equal-height transmission line when it is static is: according to the position coordinates of the tower and the catenary equation, the position coordinates of the 31 equally divided nodes of the catenary segment are calculated, and the suspension point, the equal division The nodes are connected sequentially to generate a static model of the transmission line. In the case of a typhoon, th...

Abstract

The embodiment of the invention discloses a method and a system for simulating a power transmission line. The method comprises the steps of obtaining the position coordinates of equant nodes when the power transmission line is in a static state; obtaining the position coordinates of the equant nodes according to a wind deflection angle when the power transmission line is in a dynamic state; sequentially connecting suspension points with the equant nodes to generate a power transmission line dynamic model. In the embodiment of the invention, a static model and a dynamic model of the power transmission line are generated; a connecting situation of the power transmission line in a zero wind environment and a waving situation of the power transmission line in a typhoon environment can be vividly showed, thus the waving of the power transmission line can be simulated, and the effect of the power transmission line in the typhoon environment can be vividly showed.

Description

technical field [0001] The invention relates to the technical field of power lines, in particular to a simulation method and system for power transmission lines. Background technique [0002] With the development of information technology, the use of virtual reality and other technical means to realize the digital simulation of power equipment is of great significance to the real-time monitoring and simulation training of power equipment. General power system simulation refers to the use of virtual reality technology to virtualize real-world industrial plants and equipment in the computer, and use database technology, data acquisition and monitoring control technology to transmit the operating status parameters of production equipment back to the virtual power station system in real time In , the query management of equipment can be realized in the three-dimensional virtual scene. [0003] At present, most of the simulations about transmission lines are carried out in stati...
