Evaluation of simple Fault Location on a MV Feeder with DG, using Fundamental Frequency Components
Marvik, Jorun Irene; Høidalen, Hans Kristian; Petterteig, Astrid (Lecture, 2008)This paper looks into possibilities for locating short circuit faults on a MV feeder with distributed generation (DG). Power frequency measurements of voltages and currents are utilized for estimating the distance to the ... -
Fast protection against islanding and unwanted tripping of distributed generation caused by ground faults
Pandakov, Konstantin; Hoidalen, Hans Kristian; Marvik, Jorun Irene (Chapter, 2017)Ground faults (GF) in a feeder with interconnected distributed generation (DG) might lead to overvoltages in healthy phases even after feeder disconnection from a substation, obstacles for reclosing schemes, and safety ... -
IEC 61850 Goose Managing applications in distribution network protection and automation
Grebla, Maciej; Yellajosula, Jaya; Hoidalen, Hans Kristian; Marvik, Jorun Irene (Journal article; Peer reviewed, 2019)Introducing distributed generators into distribution networks creates problems for protection systems like electric island formations or protection blinding. Possible solutions utilizing communication aided automation in ... -
Misoperation analysis of steady-state and transient methods on earth fault locating in compensated distribution networks
Pandakov, Konstantin; Hoidalen, Hans Kristian; Marvik, Jorun Irene (Journal article; Peer reviewed, 2017)Earth fault detection and location are very important issues in distribution networks. Current methods for faulty feeder selection are based on measurements of steady-state or transient signals. The work presented here ... -
Wind farm voltage dip measurements
Marvik, Jorun Irene; Tande, John Olav Giæver; Uhlen, Kjetil (Journal article; Peer reviewed, 2014)This paper is based on continuous measurements of voltages and currents from three wind farms for a period of 1 year, and the focus is on voltage dips. The purpose is to get an overview of the characteristics and rate of ...
