Student theses
The general procedure of the Studienarbeit (SA, “student research project”) and Diplomarbeit (DA, “diploma thesis”) at the Chair of Components of Intelligent Energy Systems can be found below:
- Preliminary discussion together with the potential supervisor to get to know each other, introduction into the topic and the task assignment.
- Definition of the task assignment by the chair and mutual determination of the submission deadline (depends on the specified time in the study regulations)
- Familiarization with the topic by studying relevant literature and the support of the supervisor.
- Setting of the time schedule (e. g. Gantt chart) to ensure a timely and comprehensive completion of the task assignment.
- Execution of the experiments, model simulations, calculations, construction of test stands, establishment, verification of methods, …
- Evaluation and analysis of the results in consultation with the supervisor
- Writing the thesis
- Presenting the results in a defense (optional for student research projects for the study course Regenerative Energiesysteme RES)
Writing a thesis at our chair offers you the possibility to deepen your individual knowledge by working on theoretical or practical research topics. Your personal interests will be respected when searching or defining a topic for the assignment.
The student research project or diploma thesis will prepare you optimally to autonomously solve engineering problems and will encourage you to choose a scientific approach to problem-solving.
High Voltage
| SA/DA |
A numerical partial discharge model should be developed in order to better understand partial discharges and their influencing factors in solid insulation materials. The choice of the model rests upon a comprehensive literature review of previously implemented models. The model itself should be implemented then in the FEA software COMSOL Multiphysics in combination with MATLAB as programming interface. A parameter study will verify the functionality. An extensive documentation ensures the further use of the model. Fundamental previous knowledge of MATLAB, Python or similar is desirable |

The student research project (Studienarbeit SA) comprises a structured investigation of optimization measures for the mechanical behavior of insulation systems of rotating high-voltage machines. A literature review of existing optimization measures and their functioning principles should be compiled. Then, push-out experiments using a compression-tension machine will be carried out to determine relevant mechanical parameters of the insulation system. Microscopical analyses of the test objects help to characterize the fault mechanism and locate the rupture. The effectiveness of several optimization measures will be discussed, and recommendations formulated. |

| SA | In order to be able to characterize new solid insulating materials with regard to their conductivity at operating temperature and operating field strength, a corresponding test setup is to be developed as part of this study. Relevant standards are to be discussed in a literature review and existing implementations are to be discussed. A temperature-resistant measuring cell is to be designed with the aid of CAD software. In order to enable interference-free measurements, sources of interference are to be identified in tests and reduced using suitable methods. In order to achieve reproducible results, a suitable measurement concept should also be created. Basic knowledge of Python and CAD applications is desirable. |

Electrical contact and connections
| DA/SA | In numerous investigations, the force reduction on bolted connections with busbars was evaluated with the course of the connection force. A new evaluation of the existing and current test results is to be carried out on the course of the mean mechanical stress in the joint. |

High short-time currents generally do not heat up current-carrying connections with surface contacts more than the connected conductor. However, depending on the current intensity, the microcontacts may also heat up to a non-negligible extent. The aim of the work is to investigate the electrical-thermal behavior of current-carrying connections under load with short-circuit current and to correlate it with simple estimates of the contact temperature. |

| DA | The loads acting on an electrical connection are manifold. Up to now, finite element simulations, from which statements on contact behavior can be derived, have usually only examined the mechanics or the electrical or thermal flow field or a coupling of two of these variables. In this work, the interaction of mechanics and the electrical and thermal flow field in a model contact system is to be investigated using modern FE software. |
