  2. 1. Dispersion and risk assessment of airborne contaminants in pharmaceutical clean rooms

    Author : Berit Reinmüller; KTH; []
    Keywords : airborne contamination; clean rooms; clean zones; clothing systems; dispersion of contaminants; LR-Method; microbiological risk assessment; risk assessment; source strenth;

    Abstract : In many of today's industries, particularly in the healthcare field, special protection is required against airbornemicrobiological contamination. Clean rooms and clean zones areused to separate the ambient environment from contaminationcontrolled areas. READ MORE

  4. 2. Converter interactions in VSC-based HVDC systems

    Author : Georgios Stamatiou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Symbolic eigenvalue expressions; Frequency Domain Analysis; Droop control; Net damping; VSC; Passivity Analysis; MTDC; Poor damping; HVDC;

    Abstract : The main objective of this thesis is to perform stability and control studies in the area of VSC-HVDC. A major part of the investigation focuses on the explanation of poorly-damped conditions and instability that are linked to dc-side resonances. READ MORE

  5. 3. Analysis of VSC-based HVDC systems

    Author : Georgios Stamatiou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC; MMC; MTDC; Poor damping; Symbolic eigenvalue expressions; Droop control; Passivity Analysis; Net damping; Frequency Domain Analysis; VSC;

    Abstract : The main objective of this thesis is to perform stability and control studies in the area of VSC-HVDC systems. A major part of the investigation focuses on the development of procedures, whose aim is to understand, explain and avoid poorly-damped conditions or instability that may appear due to dc-side resonances, which stem from the interaction of converters and passive elements in such systems.
