    • Event Detection and its Signal Characterization in PMU Data Stream 

      Negi, Sanjay Singh; Kishor, Nand; Uhlen, Kjetil; Negi, Richa (Journal article; Peer reviewed, 2017)
      The potential application of signal processing techniques is not only to detect the event but also to characterize them according to physical disturbance. In this paper, event detection and its characterization algorithm ...

    • Event signal characterization for disturbance interpretation in power grid 

      Negi, Sanjay S.; Kishor, Nand; Negi, Richa; Uhlen, Kjetil (Chapter, 2018)
      This paper presents the signal processing approach to detect and characterize the physical events that occur in power system using PMUs signals. A small window is applied so that the extracted spectral features belong to ...

    • Post-processing algorithmfor damped and step-change events detection in PMU signals 

      Negi, Sanjay Singh; Kishor, Nand; Uhlen, Kjetil; Negi, Richa (Chapter, 2017)
      The study presents an algorithm using signal processing techniques to screen PMUs data for events. The algorithm can be applied on multiple PMUs data for possible events detection and their display. The algorithm analyze ...
