6 The challenge of E2Q: ULYSSES.- INNOVATION 2.- ELECTRICAL CONSIDERATIONS: VERSATILITY 3.- SAFETY OPERATION 4.- 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. FINISHED AT THE END OF 2005 BY AREVA T&D IBERICA (Madrid, Spain) 6

7 7 The challenge of E2Q: ULYSSES 5.- ACCREDITATION E2Q realization of the test with its mobile laboratory LCOE measurement and accreditation ENAC ISO 7025 Joint venture, first certifications expected at the end of March 2006
