    Sammanfattning : This thesis concerns the design of transmitter-receiver chains for widebandradar systems. The transmitter side employs one, or several, highly flexiblesignal generators, which are able to generate signals with a large bandwidth. LÄS MER

  7. 5. On Deep Machine Learning Based Techniques for Electric Power Systems

    Författare :Ebrahim Balouji; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep Learning; Cable faults; phase locked loop; Flicker; Harmonics and Interharmonics; Reinforcement learning; Voltage Dip; Active Power filter; Machine Learning; Voltage fluctuation; Partial Discharges;

    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
