Title    Research on the method of stress calculation for transmission line based on MATLAB and its general program    implementation
Abstract
With the continuous changes of the global environment, all kinds of extreme weather appear more and more frequently in China. These extreme meteorological often easily lead to the fault of the transmission line of the power grid. The reason of the analysis is that the change of the meteorological parameters caused the great change of the power line. Once the stress occurred great changes, will lead to the break of the transmission line and tower, such as the collapse of a series of serious accidents. In order to explore the effect of these parameters on the stress of transmission line. In this paper, the accurate calculation of the stress of transmission line is calculated. And the model is programmed by MATLAB software, Finally, the graphics interface is produced by GUI. This paper uses a number of examples of this program can calculate various span, analysis of influence of meteorological parameters on transmission line stress. 源`自*六)维[论*文'网www.lwfree.cn
