1. 1. Protection Strategies to Mitigate Major Power Systems Breakdowns

   Författare :Mattias Jonsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system protection schemes; transient instability; distance protection; power swing detectors; voltage instability; generator coherency; wide area protection; out-of-step protection;

   Sammanfattning : This thesis deals with new methods to improve the performance of power system protection in the case of voltage- and transient instability. These methods are designed primarily to mitigate power system breakdown. Relay algorithms are proposed where conventional distance protection is combined with additional relay criteria. LÄS MER

3. 2. Design of Time-to-Digital Converter Circuits for 3D Time-of-Flight Measurements

   Sammanfattning : The three-dimensional view of the world is something that we often take for granted, a phenomenon that has proven challenging for machine vision applications in which description of the environment requires the relative position and motion of different objects in the scene. Currently, range imaging (RIM) measurements are based on digital imaging technology and are merged with the ability to measure the distance to the corresponding object point in each pixel. LÄS MER
