Description

Technical field: [0001] The invention relates to the field of transmission lines, and more specifically relates to a method for establishing a finite element model of a transmission line tower line system. Background technique: [0002] In recent years, with the rapid development of the national economy and the continuous advancement of science and technology, the demand for electric energy has continued to increase. In order to meet the development of social needs, my country's power grid construction has developed rapidly, and ultra-high voltage and ultra-high voltage technologies have been widely used. [0003] Large spans and high towers are the prominent features of EHV and UHV. In the design of ordinary transmission towers, the interaction of tower-line coupling is usually ignored. However, due to the characteristics of large spans and high towers of EHV and The interaction model of line coupling is quite different from the actual situation. Therefore, establishing a f...
