1. 1. Detection and location of HVDC commutation faults from PMU data

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Alejandro Belinchon Calderon; [2018]
   Keywords : HVDC-links; HVDC converters; Commutation failures; Phasor measurement units PMUs ; Electric power systems; Wide Area Measurement systems WAMS ; Standard IEEEC 37.118; Single-line to ground faults; Three-Phase faults; Fault detection and location; Nordic 32; DigSilent-PowerFactory; PSCAD; MATLAB-Simulink; Symmetrical components.; Technology and Engineering;

   Abstract : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. READ MORE

3. 2. Utvärdering av förmågan hos Wet Area Mapping (WAM) att beskriva markbärigheten på skogsmark intill vattendrag

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Jon Wikström; [2015]
   Keywords : miljöhänsyn; skogsbruk; Wet Area Mapping; körskador; markbärighet; environmental consideration; forestry; rutting; ground bearing capacity;

   Abstract : Att påverka marker nära vattendrag och sjöar medför en särskilt stor risk att förorena och försämra vattenkvaliteten i vattendragen. Risken att påverka kvaliteten i vattnet är kopplat till markens fukthalt, bl. a. via att ökad fukthalt medför ökad risk för körskador. READ MORE

4. 3. Traffic Modeling and Evaluation of QoSschemes in Wide Area MonitoringSystem

   University essay from KTH/Industriella informations- och styrsystem

   Author : Björn Johanson; [2013]
   Keywords : ;

   Abstract : To prevent a power grid from having disturbances that may, in a worst case scenario, blackout entire countries, Transmission System Operators (TSO) want to be able to see what happens in different parts of the network faster, to have time to do the necessary changes and regulate the power grid. For this reason, a new technology called PMU-based Wide Area Monitoring System (WAMS) has been introduced to allow the real-time monitoring of the power grid. READ MORE

6. 5. Synchronized Phasor Measurement Units : Implementation of PMU Algorithm on HVDC Control Platform

   University essay from KTH/Industriella informations- och styrsystem

   Author : Samarth Deo; [2013]
   Keywords : PMU; PDC; HVDC; WAMS; GPS; IEEE C37.118.2005;

   Abstract : Power Systems most often operate in the margins of stability limits. With power grids becoming even more automated now, Phasor Measurement Units (PMU’s) and Phasor Data Concentrators (PDC’s) become essential for real-time control of the system. READ MORE
