Abstract

In the last few decades, the vast majority of world states have faced increased energy consumption using more environmentally friendly production technologies. The use of traditional renewable energies like hydro, wind and solar has been the solution found. Despite this, new technical solutions and strategies are beginning to emerge, of which Floating Solar Photovoltaic (FSPV) systems are part. In this framework, southern European countries have excellent climate conditions for reinforcing the use of solar energy...READ MORE

Abstract

SyrNemo is a European collaborative research project that deals with the development of a highly integrated air-cooled next generation E-drive (an E-drive consists of E-motor, inverter and controls) based on a Synchronous Reluctance Machine (SYRM). Its salient features are the use of ferrite magnets and a very high efficiency over a large operation range. Ultimately, any new E drive component has to prove its viability in the vehicle where not only energy efficiency but also functional behaviour is checked...READ MORE

Abstract

This paper deals with the mitigation of the influence of electromagnetic conducted emissions in low voltage grids, which can be performed using different filtering methods. Due to the relatively young age of the electromagnetic compatibility domain, the specific terminology is not yet fully consecrated. That is why the specific literature abounds in a bunch of definitions and notions, incomplete, redundant, or worse, even contradictory...READ MORE

Abstract

Power supply reliability is one of the critical elements of power quality. Its improvement in medium voltage distribution systems in urban areas is typically achieved by cabling. Unfortunately, this approach is often too expensive to be applied in rural areas. One of the possible alternative solutions that can be used in rural medium voltage distribution networks is permanent closed-loop operation. It requires the introduction of additional reclosers with properly parametrized protection relays enabling directional protection...READ MORE
