  5. 3. Distributed Signal Processing in Digital Substations : Integrating High Sampling Rate Measurements at the Process-Level

    Author : Fabian Hohn; Lars Nordström; Peter Crossley; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication networks; digital signal processing; digital substation; field-programmable gate array; filter design; IEC 61850; IEC 61869; power system protection; substation automation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. READ MORE

  6. 4. Thermal Study of a Submerged Substation for Wave Power

    Author : Antoine Baudoin; Cecilia Boström; Didier Saury; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; marine substation; heat transfer; natural convection; CFD; FEM; thermal management;

    Abstract : At the Division of Electricity of Uppsala University, a wave power concept is being developed.It relies on wave energy converters, one buoy and one linear generator placed on the seabed, connected together to a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

  7. 5. Mitigation of Power-Frequency Magnetic Fields With Applications to Substations and Other Parts of the Electric Network

    Author : Ener Salinas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation; power-frequency magnetic fields; EMC; FEM; busbars; transformers; field mitigation; eddy currents;

    Abstract : In recent times, electromagnetic emissions from various electrical components have induced more than one debate whether they represent a harmful influence to our health. In addition, interferences caused by power frequency magnetic fields (PFMFs) on electron beam based electronic equipment (e.g. READ MORE
