Potential und Chancen der Photovoltaik aus industrieller Sicht

Photovoltaic (PV) energy production is an established and reliable technology. From the cost perspective, PV installations today are mainly operated economically in non-grid connected applications. In order to improve the cost situation, the present silicon wafer technology will be further developed for ultrathin tricrystalline cells. In the next step the follow-up generation of chalkopyrite-based CIS thin film solar cells aims at low-cost mass production.     

Schlüsseltechnik Mikroelektronik: Chancen und Herausforderungen

Microelectronics is omnipresent in everyday life, whether as pocket calculators, chip cards for monetary transactions, or as data carriers, machine controllers, telecommunication systems with various services, etc. Integrated circuits contribute in manifold ways to facilitate and accelerate work and to improve comfort and environmental compatibility. Within the next 20 years, semiconductor technology will provide a further enormous expansion of integration density of electronic functions on an IC, as well as a dramatic increase in data processing speed.     

Internet und Intranet sind mehr als Hilfen bei der Ausbildung

The earlier CBT (Computer Based Training) has turned into WBT (Web Based Training). The initial attempts to use the WWW for educational purposes by just offering a sequence of WWW pages with some email or chat support have not turned out to be overly successful. It has become clear in the meantime that much more is needed, something that we call a GEneral Networked Training and Learning Environment with the nice acronym GENTLE. A system of this kind has been developed at the speaker’s institute, see http://wbt.iicm.edu. However, even such general environments can only be properly understood and can only develop their full potential if they are seen as pieces of a more general concept called “Knowledge Management”: part of general Knowledge Management (KM) is Knowledge Transfer (KT) and this is exactly what WBT is all about. In this talk we will first explain KM and its relation to KT, and how systems such as GENTLE fit into this general picture.     

Dissipativitäts- und passivitätsbasierte Regelung nichtlinearer mechatronischer Systeme

The socalled dissipativity- and passivity-based control strategies take advantage of the physical nature of the nonlinear plant to be controlled, in particular the internal and external energy flows. Consequently, this enables a unifying analysis and synthesis of coupled mechatronic systems for the purpose of the controller design. The feasibility of these design strategies will be shown by means of two different applications in the field of electromechanical and hydraulic systems.     

Das Tor-Konzept für die Modellierung und Regelung komplexer dynamischer Systeme

The generalization of Hamiltonian systems with dissipation in combination with the port-concept leads directly to the class of port-controlled Hamiltonian systems with dissipation, or PCHD-systems for short, which are appropriate for modeling and control of nonlinear mechatronic systems. By the help of the structural properties of PCHD-systems it is in general possible to show passivity and to prove stability of the closed loop, if the closed loop system is represented by a PCHD-system. Combining passive systems with ideas from the flatness-based feedforward control, one is able to achieve excellent tracking performance and disturbance rejection at the same time.     

Prognose und Simulation von Flickererscheinungen in öffentlichen Netzen und in Industrieanlagen

Today prediction and limitation planning of flicker is of increasing importance. In medium voltage networks for example the number of wind generators is rapidly increasing, which show high power fluctuations resulting in flicker problems. In the low voltage networks of industrial installations especially spot welding machines necessitate prediction and planning of power quality. It has been found that classical load flow simulations are time-consuming and lead to unrealistic results. In future new fast simulation methods are necessary, enabling to predict flicker, which is caused either by stochastic load behavior or by stochastic generation by wind turbines or photovoltaic.     

Sicherheit und rechtliche Herausforderungen in Bezug auf Cloud Computing und Kritische Infrastruktur-IT

The prevalence of machine-to-machine (M2M) will continue to increase because of the connection and interlinking of services in the domain of critical infrastructures (e.g. “smart grids”, traffic management or surveillance systems). This is leading to a constant rise of required computational and storage resources. As field systems typically offer only limited computing and storage capabilities and as many applications require a global view to integrated data from various devices, a natural location to store data and perform analysis tasks is in the Cloud, where an abundance of flexible resources can be used. However, this results in a number of security and privacy challenges in combination with some legal and technical considerations that need to be addressed. In this paper, we will investigate and categorize the above challenges associated with using the Cloud in a critical infrastructure and M2M context.     

Investitionsbedarf und zukünftige Bedeutung der Versorgungssicherheit in Europa und Österreich

Europe urgently needs an investment boom in the fields of power generation, transmission, and distribution. Until 2030 the current generation portfolio will de facto have to be replaced. Especially in the liberalized market environment, investors rely on a clear and uncompromising regulatory environment, which is still lacking today. The investments required will only happen, if political commitment results in easier and fast-track licensing procedures. Clearly formulated energy targets for Europe and uncompromising free market approaches at EU and national level are the key to guarantee trust in a sufficiently stable regulatory environment. They are also a prerequisite for ensuring that market signals for investments will be acted upon.

Produktionsmanagement in kleinen und mittleren Unternehmen

Production organisations are confronted above all with the problem to adjust products according to continuously changing market demands. Highest priority must be given to the orientation to customer specifications. In an environment of Intelligent Manufacturing it is possible to implement appropriate strategies in computer systems whereas efficiency of production flows and business results will increase sufficiently.     

Monitoring und Diagnostik in der Hochspannungstechnik

To use electrical resources economically, it is useful to know the available remaining service life of used resources. With the use of technical diagnostic systems significant variables can be recorded. On the basis of these variables (temperatures, optical, electrical and mechanical variables etc.), conclusions concerning the future behaviour of the technical resources will be made. Based on the received data information, modifications in the operation behaviour can be diagnosed; tendencies can be detected and suitable counter measures can be set. The so-called “partial discharge measuring technique” can be regarded as a subsection and an important diagnostic equipment. For the detection of partial discharges different methods can be used.
