Such systems play an increasingly important role in a large variety of fields, such as manufacturing, health care, environment, transportation, defence, and so on. LÄS MER

3. 7. Oviposition cues as a tool for developing a new malaria control strategy

   Författare :Lynda Eneh; Anna-Karin Borg-Karlson; Willem Takken; KTH; []
   Nyckelord :Anopheles gambiae; Malaria; Oviposition; Volatile compounds; GC-MS; DGGE; Sorption; Fungi; Bacteria; Physicochemical parameters; Nut grass; Bermuda grass; Anopheles gambiae; Malaria; Äggläggning; Flyktiga ämnen; GC-MS; DGGE; Sorptionen; Svampar; Bakterier; Gräs; Kemi; Chemistry;

   Sammanfattning : Anopheles gambiae sensu lato mosquitoes are among the dominant malaria vectors in sub-Saharan Africa. However, not much is known about the oviposition behaviour of these species necessary for the development of malaria vector control strategies. LÄS MER

4. 8. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM

   Författare :Paulo Fischer de Toledo; Hans-Peter Nee; Gustaf Ohlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Keywords : HVDC transmission; LCC – Line-commutated Current-source Converter; STATCOM; VSC – Voltage Source Converter; Space-Vector complex vector ; transfer-function; frequency-domain analysis; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. LÄS MER

5. 9. VSC-HVDC for Industrial Power Systems

   Författare :Cuiqing Du; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage dips; vector controller; VSC-HVDC; outer controller; current limit; industrial power systems.;

   Sammanfattning : The recent developments in semiconductors and control equipment have made the voltage source converter based high voltage direct current (VSC-HVDC) feasible. Due to theuse of VSC technology and pulse width modulation (PWM) the VSC-HVDC has a number of potential advantages as compared with classic HVDC, such as short circuit current reduction, rapid and independent control of active and reactive power, etc. LÄS MER

7. 10. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power

   Författare :Georgios Mademlis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage balancing; Maximum Power Point Tracking MPPT ; Medium Voltage Converters; Multilevel Space-Vector-Modulation; Neutral point clamped converter NPC ; Subsea kite; Tidal power;

   Sammanfattning : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.
