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 credits | 2V + 2U | J. Smajic | |

Abstract | 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. | ||||

Learning objective | 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. | ||||

Content | 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) | ||||

227-2037-00L | Physical Modelling and Simulation | 6 credits | 4G | J. Smajic | |

Abstract | This module consists of (a) an introduction to fundamental equations of electromagnetics, mechanics and heat transfer, (b) a detailed overview of numerical methods for field simulations, and (c) practical examples solved in form of small projects. | ||||

Learning objective | Basic knowledge of the fundamental equations and effects of electromagnetics, mechanics, and heat transfer. Knowledge of the main concepts of numerical methods for physical modelling and simulation. Ability (a) to develop own simple field simulation programs, (b) to select an appropriate field solver for a given problem, (c) to perform field simulations, (d) to evaluate the obtained results, and (e) to interactively improve the models until sufficiently accurate results are obtained. | ||||

Content | The module begins with an introduction to the fundamental equations and effects of electromagnetics, mechanics, and heat transfer. After the introduction follows a detailed overview of the available numerical methods for solving electromagnetic, thermal and mechanical boundary value problems. This part of the course contains a general introduction into numerical methods, differential and integral forms, linear equation systems, Finite Difference Method (FDM), Boundary Element Method (BEM), Method of Moments (MoM), Multiple Multipole Program (MMP) and Finite Element Method (FEM). The theoretical part of the course finishes with a presentation of multiphysics simulations through several practical examples of HF-engineering such as coupled electromagnetic-mechanical and electromagnetic-thermal analysis of MEMS. In the second part of the course the students will work in small groups on practical simulation problems. For solving practical problems the students can develop and use own simulation programs or chose an appropriate commercial field solver for their specific problem. This practical simulation work of the students is supervised by the lecturers. | ||||
