Air power transmission lines (PTL) are widely used for electricity delivery. To prevent possible crashes we should analyze dynamic response of air PTL under different external loads. In this paper the method of modeling dynamics of an air PTL is presented. Metal pylons simulated by reduced finite elements models. These models can be obtained using experimental system identification methods, but in...
In this paper the description of the developed subroutine on the ANSYS Parametric Design Language (APDL) for automatic building of finite-element model of the typical metal pylons (supports) of air power transmission lines is presented. The proposed algorithm of the subroutines and structure of preparation of initial data allows user to edit and create models of typical constructions of pylon according...
