The students will master linear time-invariant systems as well as their mathematical description. They will understand the basic principles of the generation of electrical energy from different primary energy resources as well as their most essential properties, advantages and disadvantages. As a result, the students will develop an awareness of social and ethical responsibility concerning the usage of non-renewable energies. They will have an overview over the relationships between relevant components of the electricity supply and understand the resulting structures. The students will master all of the essential electrical and electromechanical devices and machines based on the physical understanding of the derived models and they will be able to apply them based on appropriate working techniques. This includes the basic mathematical equations which link the physical quantities of the devices and machines. The profound knowledge about electrical devices and machines (ranging from mW to MW), which are relevant to and required in many technical fields, will enable the communication with specialist of different subjects. The imparted technical knowledge about the application of energy is particularly important in view of the current discussion on the energy and climate issues. It enables the students to make reasonable statements in public discussions and represent reliable positions.
Following the lectures of "General Electrical Engineering 1 and 2" this lecture connects with the discussion on linear time-invariant systems. As an introduction to power engineering the lecture gives an overview on the electricity supply, covering the generation, transmission (over long distances), distribution (over short distances) and the use of electrical energy. The mechanisms and operating principle of the most important types of power plants, particularly corresponding to its primary energy source (coal, gas, oil, nuclear power, water, wind, solar, etc.) is shown. In this context, the term of energy and efficiency are defined. The basic principles of the transmission and distribution of electrical energy by means of a three-wired system (“three-phase currents”) as well as essential mathematical concepts (e.g. symmetrical components) are explained. Then, the lecture turns to significant electrical and electromechanical devices and machines, which are relevant to the generation, transmission, distribution and the use of electrical energy. First, the fundamental electromagnetic principles of how machines are operating, will be discussed. A detailed description of the transformer, which is the most important asset for the transmission and distribution of electrical energy, as well as of the DC machine, for which the fundamental electromagnetic principles can be clearly shown, will be given. In this context, the generation of DC voltages from an AC or three-phase voltages is also discussed, for which power electronics components are being applied. In the last lecture sections, the principle of three-phase machines based on a rotating magnetic field are introduced. The operation behavior of the synchronous generator, which plays a significant role in the generation of electrical energy and formation of the power grids, as well as the induction machine with fixed and variable grid frequency are presented.
