How to model an Electric Variable Transmission in Simulink?

How can we extensively model the physics and working of an Electric Variable Transmission which can be used for Hybrid Electric Vehicle. It is some times also referred to as Dual mechanical port machine or a Double Rotor Machine.

Hi @Divyakumar,

I understand you are looking to model underground transmission lines in MATLAB/Simulink. This can be done using blocks available in Simscape Electrical.

Few of the blocks that can be used are:

1. PI Section Line – models a short cable segment with lumped R, L, and C parameters.

2. Distributed Parameters Line (Frequency-Dependent) – Implements an N-phase distributed parameter line model with lumped losses and provides a more accurate representation for long underground cables.

3. AC Cable (Three-Phase) Block – specifically designed for power cables, including sheath modeling and bonding configurations.

For detailed MATLAB examples, refer to the below documentation links:

• AC Cable with Bonded Sheaths: https://www.mathworks.com/help/sps/ug/ac-cable-with-bonded-sheaths.html
• Four Coupled 66-kV Cables: https://www.mathworks.com/help/sps/ug/computation-of-r-l-and-c-cable-parameters.html

I hope this is helpful!
