Tutorial - Study Committee C4 - Modelling and Simulation of Electromagnetic Transients in Lines, Cables, and Gas-Insulated Substations

Presenters: Haoyan Xue (Polytechnique Montréal, Canada), Jean Mahseredjian (Polytechnique Montréal, Canada), Swetha Srinivasan (Mitsubishi Electric Power Products Inc. , USA)

This session presents an in-depth overview of state-of-the-art theories and methodologies for electromagnetic transient (EMT) simulations of transmission lines, cables, and gas-insulated substations (GIS).
It introduces an updated set of modeling guidelines utilizing EMT-type simulation tools alongside advanced numerical electromagnetic techniques, including the finite element method (FEM), method of moments (MoM), and finite-difference time-domain (FDTD) approaches.
The presentation also provides comprehensive guidance on the parameterization, representation, and interfacing of GIS components to ensure consistency and compatibility across different simulation platforms.
In addition, it presents benchmark cases for overhead lines and underground/submarine cables in both AC and DC applications to highlight recent advances in the field.
The field measurements are also incorporated to cross-validate simulation results, reinforcing the accuracy and reliability of the proposed modeling approaches.
