Juliacon 2024

We describe the TU Delft master course EE4375 entitled “Finite Element Method in Electrical Engineering Applications”. The course material is available at github.com/ziolai/finite_element_electrical_engineering . The course is spread over seven weeks. Each week, the students attend two hours of lectures and take part of four hours of lab sessions. The lectures introduce a set of mathematical models for electric and magnetic fields. The lab sessions allow the students to implement these models in Julia. We also discuss two project-based assignments of EE4375 in which we collaborate with industrial partners.

In the first student project, we collaborate with the distribution system operator STEDIN Rotterdam to model the effect of new components in the infrastructure for energy distribution. Examples of such components are solar panels, electrical vehicles and batteries. These new components are expected to generate harmonics at larger frequency than the base frequency of 50 Hz. Without proper counter measures, these higher frequencies are expected to cause damage to the existing infracstructure. The goal of the project is to predict the effect of higher harmonics on the aging of distribution substations. This will allow to design suitable counter-measures.

In the second student project, we join forces with TNO to solve integro-differential equations to describe the magnetic signature of naval ships. This information will allow to design a system of current-carrying coils on board the ship that renders the ship neutral for disturbances in the earth magnetic field.
