Two global precise times for synchronization

A system for 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, comprising:

• a synchronizer for 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,
• an associator for 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,
• wherein said local clock generation circuitries associated with data processors of a second subset of the data processors have a peak-to-peak tracking jitter less than said predetermined threshold value,
• a first controller for controlling at least one of said system elements at least partly by means of a data processor from said first subset of data processors susceptible to the jitter of the local clock generation circuitry associated with the data processor from the first subset of data processors, and
• a second controller for controlling at least one of said system elements at least partly by means of a data processor from said second subset of data processors on the basis of said at least one reference signal while being susceptible to the jitter of the local clock generation circuitry associated with the data processor from the second subset of data processors,
• thereby utilizing said second subset of data processors for high precision control in the wind power system.
