Transcript

  • 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. 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. 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
  • 4. 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. 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. ABB - DMS 600 TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  • 7. Aidon - AMR TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  • 8. Electrix - Quality Module TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
  • 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. PowerQ - PQNet TAMPERE UNIVERSITY OF TECHNOLOGY Department of Electrical Energy Engineering Petri Trygg, Reseacher 18.6.2009
