Title:
METHOD AND SYSTEM FOR CONTROLLING A WIND POWER SYSTEM COMPRISING DATA PROCESSORS SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2010/136041
Kind Code:
A3
Abstract:
Method of controlling a wind power system comprising a plurality of system elements, said wind power system including a plurality of data processors distributed in said system elements, the method comprising the steps of: synchronizing at least a part of said data processors to at least one reference signal distributed to said data processors from a time synchronization arrangement, associating said data processors with local clock generation circuitries, wherein said local clock generation circuitries associated with data processors of a first subset of the data processors have a peak-to-peak tracking jitter higher than or equal to a predetermined threshold value and wherein a second subset of the data processors have a peak-to-peak tracking jitter less than said predetermined threshold value, controlling at least one of said system elements at least partly by means of a data processor from said first or second subset of data processors.
