6. Extracting Information from Voltage-Dip Monitoring
Sammanfattning : A voltage dip is a short duration reduction in voltage magnitude due to a short duration increase in current magnitude. Causes of dips are, among others, electrical faults, large motor starting, transformer energizing and failure of power-electronic converters. LÄS MER
7. On Control of Grid-connected Voltage Source Converters - Mitigation of Voltage Dips and Subsynchronous Resonances
Sammanfattning : Custom Power and Flexible AC Transmission Systems (FACTS) denote the application of power electronics in distribution and transmission networks, respectively. Custom Power is the application of power electronics to improve the quality of power distribution for sensitive industrial plants. LÄS MER
8. On Deep Machine Learning Based Techniques for Electric Power Systems
Sammanfattning : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. LÄS MER
9. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER
10. Artificial Intelligence-Based Characterization and Classification Methods for Power Quality Data Analytics
Sammanfattning : One of the important developments in the electric power system is the fast increasing amount of data. An example of such data is formed by the voltages and currents coming from power-quality measurements. LÄS MER
