Simulation of Redial Thermal and Temperature Distribution of ACSR Conductors Implementing Finite Element Method of Events in Power plants

Produced heat in overhead transmission lines is resulted from its current and so the distribution of current in these conductors is very important. In prototype models of overhead transmission lines, due to small cross section of conductors, besides produced heat, total cross section of conductor is supposed to be isotherm, but in new thermal analysis of conductors this assumption is invalid. Moreover implementing some of particular methods like thermal loss (Joule effect) for de-icing of power transmission lines requires precise thermal and temperature analysis of overhead lines conductors. In this paper at first we obtain thermal distribution of ACSR conductors then the thermal distribution of lynx conductors is analyzed by Using MATLAB software. In this analysis lynx conductor is supposed to be uniform and without strand effects, afterward by using ANSYS software which solves problems on the base of FEM method, we assess effects of strands.
