COMSOL Day: Electrical Power Systems

See what is possible with multiphysics simulation

Power distribution infrastructure and the grid have been brought into focus lately due to recent catastrophic climate events. COMSOL Day: Electrical Power Systems is an online event focused on these issues, where invited speakers and COMSOL staff will introduce you to and delve into the aspects of simulating such.

Apart from looking at the challenges facing us as we deal with a world with increasingly hostile environmental conditions, the sessions will focus on modeling techniques for applications and components such as coils, inductive heating, electric motors and generators, transformers, and cables.


COMSOL Presentation
Parallel Session
Transformer Design: A Multiphysics Approach

The quality of transformers is characterized by effects covering a wide range of physics: electromagnetic efficiency, electric and magnetic losses, stray fields, heating, and even noise emission. Discover how multiphysics simulation can help you predict the performance of transformers.

Tech Café: Meshing in Low-Frequency Electromagnetics

Generating a mesh that is both fine enough to capture the physical phenomenon and give accurate results and computationally efficient is a compromise and requires different meshing techniques. During this Tech Café, we will discuss how best to generate meshes for typical situations encountered in low-frequency EM models, including boundary layer meshes, infinite elements, rotating domains, and thin layers.

COMSOL Presentation
Tech Café: Magnetic Material Models

Ferromagnetic materials are at the heart of motors, transformers, inductors, and many other electromagnetic devices. A challenge with simulating these applications and devices is to consider the variable and nonlinear properties of ferromagnetic materials, such as magnetic saturation, hysteresis, and anisotropy. Join us in this Tech Café to discuss and ask questions to COMSOL technical staff about techniques for modeling magnetic materials and phenomena, such as iron loss estimation, using Steinmetz or Bertotti loss models for fundamental frequency and harmonics, and explicit hysteresis modeling.

Invited Speaker
Parallel Session
Generators, Switches, and Magnetic Devices

In this session, we will discuss the details of modeling electrical machines and different multiphysics aspects using COMSOL Multiphysics®. We will show you how to model different types of electric motors, such as induction motors, permanent magnet motors, LVDT, generators, electromagnetic switches, magnetic pumps, and magnetic valves. We will discuss how to compute winding and core losses for thermal analysis in order to address the multiphysics aspects of these machines. You will also see how electromagnetic forces can be coupled with different physics, such as structural mechanics and acoustics.
