  1. 2nd European transformer workshop Rome November, 24 th Polish Super trafo Moje dokumenty/ECI/Prezentacje/supertrafo

  2. Project goals • High visibility demonstration of the distribution transformer energy savings / CO2 reductions together with: • economics related to energy-efficient transformers • technical capability aspects • A basis for communications work to promote EE distribution transformers • A framework for replication Moje dokumenty/ECI/Prezentacje/supertrafo

  3. Project place • Three countries (Paneuropean approach) : • Poland; residential • Wrocław or • Łódź • Netherlands; Utrecht • Italy; Milano Moje dokumenty/ECI/Prezentacje/supertrafo

  4. Project phases September 2000 – September 2001 PROJECT START-UP SITE SELECTION RFQ SUPER TRANSFORMER INSTALLATION & METERING COMMUNICATION UTILITIES / END MARKET TRANSFORMER PRODUCER Moje dokumenty/ECI/Prezentacje/supertrafo

  5. Sites (Poland) • Two utilities in Poland are the candidates: • Wrocław (potential link to building rewiring campaign) • Łódź Both are supporters of energy efficiency policy • 3 to 4 installations 100 – 630 kVA per site Moje dokumenty/ECI/Prezentacje/supertrafo

  6. Wrocław Population: 625.000 (1995) Area: 293 km2 Utility: ZAKŁAD ENERGETYCZNY WROCŁAW Area: 6 287 km2 No of consumers: 446 909 Electric Energy sales: 2 867 613 MWh Lines: HV=926 km, MV=6 034 km, LV=7 909 km Substations: HV/MV=31 pcs, MV/LV=4743 pcs Total power of transformers: 2 523 MVA Moje dokumenty/ECI/Prezentacje/supertrafo

  7. Łódź Population: 838.000 (1995) Area: 294 km2 Utility: ŁÓDZKI ZAKŁAD ENERGETYCZNY Area: 1 523 km2 No of consumers: 508 679 Electric Energy sales: 2 460 043 MWh Lines: HV=378 km, MV=3 860 km, LV=8 607 km Substations: HV/MV=33 pcs3, MV/LV=3225 pcs Total power of transformers: 2 281 MVA Moje dokumenty/ECI/Prezentacje/supertrafo

  8. Polish partners Moje dokumenty/ECI/Prezentacje/supertrafo

  9. Polish figures general • Population: 38,5 mln • Area: 304,5 km2 • Power consumed (1999): 95,156 TWh (max. 128 TWh in 1988) • Peak demand (1999): 22,821 MW Moje dokumenty/ECI/Prezentacje/supertrafo

  10. Polish figures - losses • Losses HV,MV,LV in 1989: 10,7 TWh (8,5%) • Medium transformation / total transmission and distribution losses: 18,2% • Transformer age distribution: Moje dokumenty/ECI/Prezentacje/supertrafo

  11. Transformer selection • Load profile matching • Above CC’ (HD 428) level • The lowest cumulated costs of transformation as the main criteria • Purchase costs • No load and load losses during lifecycle time (including new capacity avoidance) Moje dokumenty/ECI/Prezentacje/supertrafo

  12. Metering • Continuous power, cos Ф, no load and load losses calculated (model and factory data) or measured ( directly by two –in and out - energy counters or indirectly by Uin, Iin and oil temperature measurement) • Comparing the actual losses with replaced trafo losses computation saving Moje dokumenty/ECI/Prezentacje/supertrafo

  13. Communication • Polish specific CO2 /kWh conversion figure • Continuosus computation to CO2 emmision reduction kWh On line Web site communication CO2 Moje dokumenty/ECI/Prezentacje/supertrafo
