227-0536-00L | Multiphysics Simulations for Power Systems This course is defined so and planned to be an addition to the module "227-0537-00L Technology of Electric Power System Components". However, the students who are familiar with the fundamentals of electromagnetic fields could attend only this course without its 227-0537-00-complement. | 4 KP | 2V + 2U | J. Smajic | |

Kurzbeschreibung | The goals of this course are a) understanding the fundamentals of the electromagnetic, thermal, mechanical, and coupled field simulations and b) performing effective simulations of primary equipment of electric power systems. The course is understood complementary to 227-0537-00L "Technology of Electric Power System Components", but can also be taken separately. | ||||

Lernziel | The student should learn the fundamentals of the electromagnetic, thermal, mechanical, and coupled fields simulations necessary for modern product development and research based on virtual prototyping. She / he should also learn the theoretical background of the finite element method (FEM) and its application to low- and high-frequency electromagnetic field simulation problems. The practical exercises of the course should be done by using one of the commercially available field simulation software (Infolytica, ANSYS, and / or COMSOL). After completing the course the student should be able to properly and efficiently use the software to simulate practical design problems and to understand and interpret the obtained results. | ||||

Inhalt | 1. Elektromagnetic Fields and Waves: Simulation Aspects (1 lecture, 2 hours) a. Short review of the governing equations b. Boundary conditions c. Initial conditions d. Linear and nonlinear material properties e. Coupled fields (electro-mechanical and electro-thermal coupling) 2. Finite Element Method for elektromagnetic simulations (5 lectures and 3 exercises, 16 hours) a. Scalar-FEM in 2-D (electrostatic, magnetostatic, eddy-currents, etc.) b. Vector-FEM in 3-D (3-D eddy-currents, wave propagation, etc.) c. Numerical aspects of the analysis (convergence, linear solvers, preconditioning, mesh quality, etc.) d. Matlab code for 2-D FEM for learning and experimenting 3. Practical applications (5 lectures and 5 exercises, 20 hours) a. Dielectric analysis of high-voltage equipment b. Nonlinear quasi-electrostatic analysis of surge arresters c. Eddy-currents analysis of power transformers d. Electromagnetic analysis of electric machines e. Very fast transients in gas insulated switchgears (GIS) f. Electromagnetic compatibility (EMC) | ||||
