1. 1. Power System Oscillations - Detection, Estimation and Control

   Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER

3. 2. On Parameter Estimation : Applications in Radio Astronomy and Power Networks

   Författare :Jonas Lundbäck; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter estimation; Antenna arrays; FMCW-radar; Polarization estimation; Fault locator;

   Sammanfattning : Signal processing is a common part of the modern society used to obtain high functionality in a vast number of applications. As the development of advanced electronics and powerful computers continue, the limit of the functionality in many systems is increased. LÄS MER

4. 3. Accurate Leakage-Conscious Architecture-Level Power Estimation for SRAM-based Memory Structures

   Författare :Minh Quang Do; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM Power Modeling; Deep Submicron; Power-Performance Estimation Tool; VLSI; Power Estimation; DSP Architecture; CMOS; Cache Power Modeling;

   Sammanfattning : Following Moore’s Law, technology scaling will continue providing integration capacityof billions of transistors for IC industry. As transistors keep shrinking in size, leakagepower dissipation dramatically increases and gradually becomes a first-class design constraint. LÄS MER

5. 4. Measurement, Modeling, and Characterization for Power-Aware Computing

   Författare :Bhavishya Goel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transactional memory; power management; energy characterization; power measurement; power estimation; power-aware scheduling;

   Sammanfattning : Society’s increasing dependence on information technology has resulted in the deployment of vast compute resources. The energy costs of operating these resources coupled with environmental concerns have made power-aware computingone of the primary challenges for the IT sector. LÄS MER

7. 5. Automating Power Quality Analysis

   Författare :Emmanouil Styvaktakis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pattern classification; expert systems; induction motors; power system transients; voltage dips; power system faults; power quality; Kalman filtering; power system monitoring; transformer saturation; short time Fourier transform;

   Sammanfattning : The increased requirements on supervision, control, and performance in modern power systems make power quality monitoring a common practise for utilities. Large databases are created and automatic processing of the data is required for fast and effective use of the available information. LÄS MER
