MATLAB Program for 3D Electromagnetic Field Calculation of 1000kV High-Voltage Transmission Lines

This MATLAB program calculates the three-dimensional electromagnetic field distribution for 1000kV high-voltage transmission lines. The implementation employs the finite element method (FEM) where the transmission line is modeled as a 3D geometric structure that gets discretized into multiple small elements. The core algorithm solves electric and magnetic field equations for each individual element, then assembles the results to obtain the complete electromagnetic field distribution across the entire transmission line system. The program incorporates material properties and cross-sectional geometry parameters of transmission lines, allowing for accurate consideration of how these factors influence electromagnetic field characteristics. This approach enhances the physical realism of the simulation results. Key functions likely include mesh generation routines, matrix solvers for partial differential equations, and field calculation modules that handle boundary conditions specific to high-voltage applications. Additionally, the program features comprehensive visualization capabilities that generate graphical representations of the computed electromagnetic field distributions. These visualization tools enable users to intuitively analyze field intensity patterns, identify hotspots, and understand spatial variations through contour plots, 3D surface plots, and vector field displays, making the results accessible for both technical analysis and presentation purposes.
