Super Trafo 2001

2nd European transformer workshop

Rome

November, 24 th

Polish Super trafo


Super Trafo 2001

Project goalsHigh 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


Super Trafo 2001

Project place• Three countries (Paneuropean

approach) :• Poland; residential

– Wrocław or

– Łódź

• Netherlands; Utrecht• Italy; Milano

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

Super Trafo 2001

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


Super Trafo 2001

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:

Super Trafo 2001

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)


Super Trafo 2001

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


Super Trafo 2001

Communication• Polish specific CO2 /kWh conversion figure

• Continuosus computation to CO2 emmision reduction
