Claim Text:
1. A wind turbine self-diagnosis procedure, comprising the steps of: a) identifying potentially defective components of a wind turbine on the basis of signs given by active alarms by using a table which relates the active alarms to the potentially defective components; b) selecting applicable diagnostic tests for said potentially defective components by using a table which relates the potentially defective components with diagnostic tests applicable to them; c) assigning to each applicable diagnostic test a weighted value directly proportionate to the number of potentially defective components to which the test applies and to the failure rate of potentially defective components covered by the test, and inversely proportionate to the duration of the test; d) performing a diagnostic test having the highest weighted value from step c); e) eliminating from the table of step b) the components checked by the diagnostic test completed in step d), recalculating the weighted values for the remaining components, and performing a diagnostic test having the highest weighted value; f) repeating step e) until all components have been checked; and g identifying potentially defective components of the wind turbine on the basis of results of the diagnostic tests performed in steps d)-f).
