Fault And Pq Monitoring Using Amr Public

  1. 1. Low voltage network fault management and power quality monitoring using AMR - experiences from first implementation Petri Trygg Reseacher Tampere University of Technology Department of Electrical Energy Engineering TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  2. 2. Concept of LV network fault and Power quality monitoring as part of smart metering TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  3. 3. Low voltage network management • The main idea is to monitor low voltage network to improve customer service • Network alarms: AMR integration to DMS • blown LV fuses • broken LV conductor (line or neutral) • broken MV conductor with or without an earth contact • over- and undervoltages • Power quality: Quality module and integration to QMS->DMS • Phase voltages • Unbalance • Voltage sags and swells • Flicker • Total Harmonic Distortion (THD) TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009

Utility testing: Koillis-Satakunnan Sähkö Project partners Utility: www.ksat.fi DMS: www.abb.fi AMR: www.aidon.fi Quality module: www.electrix.fi QMS: www.powerq.fi Source: Google maps Algorithms and testing: TAMPERE UNIVERSITY OF TECHNOLOGY www.tut.fi/set Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  5. 5. Fault Management – Case: broken zero conductor • Network coloring can show where it can be broken TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  6. 6. ABB - DMS 600 TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  7. 7. Aidon - AMR TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  8. 8. Electrix - Quality Module TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  9. 9. Power Quality – Case: night tarif vs phase voltages • Addition to graphs EN50150 quality reports, comparisons to MV measurements and voltage sags / swells comparisons TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  10. 10. PowerQ - PQNet TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
