Introduction E2Q

Energy to Quality, S.L.is created from Ingepower S.L. and Barlovento Recursos NaturalesS.L. to offer type certification of wind turbines.

OBJECTIFS:

1. CERTIFICATION OF WIND TURBINES ACCORDING TO NEW GRID CODES (Spain, Germany, Denmark, Ireland, UK, United States, etc…)

2. “EMT” MODELING OF WIND TURBINES (PowerFactory of DigSilent)

3. MODEL VALIDATION

4. CERTIFICATION OF WIND PARK

5. CERTIFICATION OF POWER QUALITY ACCORDING TO IEC 61400-21 and MEASNET

The challenge of E2Q: ULYSSES

FINISHED AT THE END OF 2005BY AREVA T&D IBERICA (Madrid, Spain)

1.- INNOVATION2.- ELECTRICAL CONSIDERATIONS: VERSATILITY3.- SAFETY OPERATION4.- CONSTRUCTION Testing whether a wind turbine rides through faults is not easy: A voltage sag generator able to perform short circuits of the desired residual voltage and the required duration is needed.

5.- ACCREDITATIONE2Q realization of the test with its mobile laboratory

LCOE measurement and accreditation ENAC ISO 17025

Joint venture, first certifications expected at the end of March 2006

The challenge of E2Q: ULYSSES

The real-life tests on Wind Turbines

Previous studies of the impact on the protection system: Site specific,

wind park or isolated site

Previous studies of the impact on the protection system of the MV and HV NETWORK: Utility

The mobile laboratory meets the requirements to test WT according to the P.O.12.3 R.E.E. and ISO 17025
