The aim of the Electrical Machines lecture is to acquire knowledge of and apply the fundamentals of the operating behavior of electrical machines. The most important electrical machines - transformers, direct current machines, asynchronous and synchronous machines - are fundamentally developed and modeled using equivalent circuit diagrams. By taking a comparative approach to the various electrical machines, students are able to familiarize themselves with the details of specific electrical machines and apply their knowledge to the development of electrical machines.

Practical course:
Various practical experiments are carried out on transformers, asynchronous and synchronous machines and their operating behavior is understood.

The course consists of the chapters Fundamentals of Electrical Machines, Transformers, Direct Current Machines, Synchronous Machines and Asynchronous Machines. As part of the fundamentals of electrical machines, basic electromagnetic arrangements are worked on, on which the application of the flow law, the law of induction and the continuity conditions in connection with electromagnetic materials are discussed. Parameterized finite element models are used for support. In the transformer chapter, the derivations of the equivalent circuit diagram in connection with non-linear behavior are worked out. The operating behavior is discussed using pointer diagrams. The DC machine is derived classically and the need for additional windings is discussed. In the transition to the synchronous machine, the DC machine is used and the synchronous machine is derived on this basis. The operating behavior is described using current locus curves and pointer diagrams. The same applies to the asynchronous machine.

Practical course:
Classic test set-ups for transformers, asynchronous and synchronous machines: open circuit, short circuit, load. Evaluation of measurement results and presentation of characteristic curves in Excel.

The theoretical knowledge is presented and explained in the lecture. In the exercise, what has been learned is deepened using practical examples.

Practical course:
The theory taught in the lecture is deepened and supplemented by practical experiments. The individual experiments are described in detail in special instructions. It is expected that the student prepares for the practical experiment, i.e. that he/she is familiar with the task and masters the underlying theory. The experiments are carried out independently in a team under professional supervision and documented and discussed in a joint paper.

Students know the structure and function of electronic control units against the background of control and regulation tasks in an overall mechatronic system. They understand the basic principles of model-based development and model-based testing, which they can classify in the context of the development of electronic control units. They are able to use the software tools MATLAB, Simulink and Simscape (MathWorks) to model and simulate software algorithms and electronic components and systems of control units. They are familiar with the difference between mathematical and component-based modeling. As an essential application example, they can also describe the functionality and control of a DC motor and can model and simulate it together with the associated control electronics using the above-mentioned tools and analyze the resulting simulation results.

The lecture provides an introduction to the technology and functionality of electronic control units using practical examples, particularly from the automotive industry. The electronic control unit consisting of hardware and software (HW/ SW) is considered as part of an overall mechatronic system:
- Control unit HW: printed circuit board and electronic components (electronics)
- Control unit SW: Control and regulation technology algorithms (computer science)
- Sensors and actuators, e.g. electromechanical components (mechanics)

Using practical examples from the field of control and regulation of DC motors, the focus is on the development of electronics and, in particular, software algorithms for control units. Model-based methods for development and testing with the professional software tools MATLAB, Simulink and Simscape (MathWorks) are used. A practical introduction to these software tools will be given:
- Possibilities for modeling and simulating dynamic systems
- Examples: RC element, RL element, DC motor (mode of operation and control)

There is also a practical introduction to model-based software development for embedded systems:
- Options for modeling and simulating software algorithms
- Options for generating code for microcontroller development boards
- Practical examples for the control and regulation of DC motors

In the lecture, the contents are presented and discussed in a fundamental way. The connections developed are then deepened in the exercises using the software tools MATLAB, Simulink and Simscape (MathWorks), among others, on the basis of practical examples.

Students should be familiar with the energy industry context of the energy market and understand basic technical, Business Studies, legal and regulatory contexts. Students should be familiar with the status quo for all stages of the value chain (generation, grids, trading and sales) and be able to discuss possible developments with their advantages and disadvantages. They should be familiar with and be able to evaluate the key issues of the energy transition. Among other things, they should be able to economically evaluate simple investments in the energy sector and understand and apply the framework conditions of the energy market. Furthermore, they should be able to independently develop and evaluate energy industry issues.

Economy, ecology and security of supply describe the target triangle of the energy industry. Together, these are  the criteria that energy systems must - at a minimum - fulfill today  Recently, a social component has apparently been added. What the status quo of the energy market looks like in relation to all stages of the value chain, i.e. decentralized/centralized generation, grids (electricity, gas, heat, H2, ...), trading and sales, what advantages and disadvantages there are in the respective future and current forms and how the respective stages of the value chain will change, will be presented and discussed in the course. The subject shows the framework conditions for the energy transition, i.e. a climate gas-neutral energy supply, across all stages of the value chain and in the context of European and international developments. Current developments (e.g. the current energy price brakes) are repeatedly examined and their implications for the energy transition are considered, as well as developments in other areas such as politics (Russia), digitalization (e.g. intelligent measuring systems, iMSys), business administration, economics and law with their effects on an energy system. Particular emphasis is placed on highlighting many practical references, some of which go beyond the energy industry context, e.g. project management, leadership behavior, SAP.

The theoretical specialist and methodological knowledge is presented, explained and discussed in the lecture. In exercises, the methodological knowledge imparted is applied and deepened using practical examples.

- Knowledge of the basic concepts and classifications of simulations
- Knowledge of the procedure for simulation studies
- Overview of the different types of simulation methods and their differentiation
- Evaluate the applicability of simulation methods for the respective task

The lecture Building Simulation introduces the methods of simulation technology. The thematic focus is on the investigation of energy-related issues in buildings. Particular emphasis is placed on the structured approach to simulation tasks. Based on a classification of simulation types, the procedure for selecting and creating suitable simulation models, carrying out simulations and evaluating the results are discussed. Different types of simulation methods are presented. These cover in particular the area of computer-aided tools. Insights are given into the mathematical modeling of the simulation tools. However, neither the lecture nor the exercise will deal with the programming implementation of the models (programming knowledge is therefore not necessary). The aim is rather to learn a structured approach to simulation and, knowing the strengths and weaknesses of the various tools, to select the most suitable one for the specific task and to be able to interpret its results correctly. Using the example of the heat balance of buildings, the procedure as well as the evaluation and interpretation of the results are deepened in the context of lectures and accompanying exercises on the computer.

The lecture provides an overview of terms, fundamentals and various methods of building simulation. In the exercises, these basic concepts are first deepened. Subsequently, based on an example building, calculations of the energy demand are carried out and compared using various methods (analytical calculation, static simulation, dynamic simulation).
