Cable Simulation with COMSOL Multiphysics

The shift toward electric vehicles and the integration of renewable energy sources into the electrical grid have led to a considerable increase in the demand for modern cable systems — in particular, cable systems that operate reliably and consistently under varying loads, over a long life cycle. To ensure an efficient, safe, and cost-effective operation over a wide range of power production and power consumption levels, simulation is used to drive the design of cables as well as auxiliary systems such as cable joints and cable termination stations. A multiphysics modeling and simulation approach can play a critical role in meeting design goals and reducing the overall development time, helping to bring innovative solutions to market faster.

The COMSOL Multiphysics^® software includes many capabilities for modeling energy transmission, including functionality for performing quasistatic, transient, and time-harmonic analyses. Additionally, the software offers functionality for coupling thermal and structural effects with electromagnetic fields as well as modeling induction heating, Joule heating, and structural stresses and strains caused by thermal expansion.

In this webinar, we will provide an overview of some of the modeling and simulation functionality in the software for evaluating high-power cables in various environments. We will also discuss the use of simulation apps and digital twins within this field.
