Lumped-Parameter Transmission Line Modeling Using MATLAB/Simulink

Accurate modeling of transmission lines is fundamental for predicting their dynamic behavior under various operating and fault conditions. This study presents a comprehensive investigation into the transient performance of a single-phase lumped-parameter transmission line using MATLAB/Simulink. The research investigates the impact of section number (N) in π-section representations on waveform fidelity and propagation characteristics. A systematic simulation framework was developed to analyze voltage and current waveforms at both sending and receiving ends, capturing key phenomena such as energization-induced oscillations, propagation delays, and the progression toward steady-state conditions. Unlike conventional tools such as ATP-EMTP, the proposed modeling approach enables flexible parameter adjustment without manual reconstruction of circuit topology, offering significant advantages in scalability and computational efficiency. The results provide deeper insight into the relationship between model segmentation and transient accuracy, offering practical guidance for both academic studies and engineering applications in power system design, stability assessment, and protection scheme development.
