Increased proliferation of the renewable energy sources (RES) brings more power electronic devices to the power distribution. Modularity on the converter level is one of the key concepts enabling flexibility, scalability and high availability of the new solutions for the distribution networks(e.g. for low voltage DC). To understand the trends and performance trade-offs it is important to describe...
The increasing amount of distributed energy resources requires significant changes to today's power systems. Most of the distributed resources are dc inherently or have a dc link. Therefore, connecting them with a dc distribution system seems beneficial. This paper presents the opportunities and challenges of dc distribution systems, starting with the requirements of future power systems. It will...
This paper summarizes development and implementation of innovative education approach based on remote education resources. The main field of concern is power electronics. Presented results are based on three representative education initiatives running in succession since year 2007. First initiative is EDIPE project (E-learning Distance Interactive Practical Education), year 2007. The remote education...
On-load tap changing (OLTC) transformers are widely used for voltage control in the distribution network. The paper provides a comparative analysis of different OLTC topologies for the design of a power electronic (assisted) tap changer. Eleven different topologies are compared on the basis of voltage and current rating of the transformer windings and tap switches, using a p.u. methodology. The topologies...
This paper describes distance laboratory for automotive electrical engineering. Designed system allows system identification and parameter tuning Learning objectives are clearly defined and their verification is included too. Designed distance laboratory provides the user with a practical experience in Power Electronic and Motion Control education.
Virtual and distance laboratories extend the application area of the Web, which leads to an openly integrated environment for sharing teaching and learning materials and hardware and software resources. In this paper distance learning and in particular the experiments are investigated. DelftWebLab for a practical experience in power electronic education is designed as a project with leading idea and...
This paper brings some practical results of research devoted to the new generation of mobile electrical power sources, based on the VSCF technology (variable speed-constant frequency). In this generation of mobile electrical power sources the driving motor and generator speed is optimally controlled in accordance with the load power thus decreasing the fuel consumption. The output voltage and frequency...
Design of an electromechanical system is multidisciplinary and so is its simulation. In this paper the three different types of co-simulation are compared and the output waveforms are presented. The co-simulation is realized between two different programs (power electronic circuit simulator - control part and finite element analysis - magnetic and mechanic model part). The simulations were realized...
